For January Mock Exam Flashcards
`Who was William Wundt?
William Wundt was the first person to call himself a psychologist. He caused psychological experimentation under experimental conditions to become the preferred method of studying human behavior. His approach was referred to as structuralism and his technique as introspection. This is because he aimed to study structure of the mind, and he did so by investigating sensation and perception (introspection).
What is introspection?
The process and manner by which a person gains knowledge about his or her own mental and emotional states.
How did Wundt use introspection?
Wundt would try and figure out mental process by asking an individuals perception on something. For instance
describe naturalistic observation
observing a situation without changing the situation at all. An example of this is David Attenborough observations of animals. This approach has high ecological validity.
describe controlled observation
The observer/researcher change/controls the situation he is observing. An example of this is Bandura’s bobo doll study, researching social learning theory. However, experiments using this approach can lack internal validity (as in demand characteristics or population validity).
describe covert observation
When the participants are unaware that they are being observed. Often reduces demand characteristics. Can cause ethical issues as it could be classed as deception or lack consent. However, according to the BPS code of ethics, they would have to be debriefed of the study, assured of confidentiality and if they were unhappy or upset by the observation, extra procedures would have to take place.
describe overt observation
Participants are aware they are being watched. Can cause the hawthorne or the F.U. effect.
describe participant observation
When the researcher/observer is part of the group they are observing (overt), or if the observer is a confederate pretending to be a part of the group (covert). Examples of this could be if an observer went to live with a special group of people (e.g. a indigenous tribe) temporarily, and recorded their interactions with them. An example of the covert kind of participant observation would be if, for example, a group of individuals pretended to be ill, so they could be admitted to hospital, so they could observe how doctors interact with patients.
describe non-participant observation
If the observer watches from a distance, or observers the actions of other’s interactions with other people. An example of this could be watching people through a one-way mirror or watching how two different people interact as a third party.
What does the mnemonic NOIR mean in terms of data?
N- Nominal Data O - Ordinal Data I - Interval Data R - Ratio Data These data forms go up in accuracy (ratio data is often more accurate or reliable than nominal data)
Describe Nominal Data
Data that relies on named categories e.g. results from a survey asking whether you prefer the sun or the daily telegraph, often presented in bar or pie charts.
Describe Ordinal Data
The levels/conditions of a data can be put in an order, e.g. highest to lowest, but are not necessarily numerical. For example what grades people got at GCSE, it goes from order A-F, but it doesn’t really have a numerical value.
Describe Interval Data
Data that is measured on a scale, ordered categories that are subdivided, so it is not just numbers, but uses numerical intervals. Examples of this include centimetres or litres ( like how many litres of water different people in a sample drink a day).
Describe Ratio Data
Continuous data with no categories. There can be no negative numerical data in ratio data, and though it is similar to interval data, the intervals between readings can be split into ratios, e.g. percentages or degrees celcius.
Describe parametric testing
The data in parametric testing must be either interval or ratio data. The sample data must also show normal distribution and must have homogeneity of variance (e.g. it mustn’t have any random spikes or anomylous results).
Describe non-parametric testing
Used when the sample data does not fill the conditions for parametric tests. Often regarded as less sensitive and powerful to specifics. This is because, unlike parametric tests, they require transformation of data.
What are Heuristics?
Heuristics are how your brain copes with making decisions and avoiding decisions and avoiding decision fatigue by not having to deliberate our choices. It is like a schema we apply instead of deliberating or making a hard decision, e.g. having a staple outfit we repeat instead of choosing one in the morning or ordering something we know we’ve liked before in the at a restaurant rather than having to choose something new from the menu.
Describe Availability heuristics
When the brain naturally determines that the likelihood of something is related to its availability. i.e. believing plane crashes are very likely, because we see them a lot on the news and television, when in fact they are incredibly unlikely. This can be used in marketing.
Describe representative heuristics
The brain’s tendency to focus on the individual rather than the bigger picture i.e. being afraid f being struck by lightning in a thunderstorm, even though there is only a 1 in 700 000 chance, or buying lottery tickets/ being disappointed by losing the lottery, despite there only being about a 1 in 14 million chance of winning.
What is framing?
The way information is presented to determine its effect on whether it is successful or not within consumers, for instance framing it in a positive light so more people are likely to buy it.
Describe how the psychological “foot in the door” technique is used in marketing
The target is given “low stakes” or obvious-answer/emotive questions ( such as “You don’t like burning down rainforests” or “Do you care that most rainforests will be depleted in 12 years?”)
They will then be asked to buy the product, and will be more likely to say yes due to coherence heuristics (the idea that once we agree with something once, it’s difficult to change our mind, even if the information changes).
How do genetics relate to the biological approach in psychology?
Certain mental disorders can be indicated genetically. This means they are inherited. For example, the COMT and SERT may be indications of an individual having OCD or Anorexia Nervosa disorder.
How is IQ related to genetics?
It is believed that 60-80% of an individual’s IQ is inherited.
How is Schizophrenia related to genetics?
Schizophrenia is 47% inherited.
How has the use of the biological approach presented weakness?
In the 1961 Sandberg misunderstanding of the XYY chromosome.
How did Sandberg misunderstand the XYY chromosome?
The Y chromosome is associated with the production of Testosterone. Testosterone is associated with aggressive and competitive behavior. Therefore, when a murderer was found with the extra Y chromosome, it was assumed that those with XYY were more aggressive and dangerous. As of this, many men with the gene were hospitalized or even incarcerated. It was later discovered that people with the gene only had 10% more testosterone and were not more aggressive, but rather taller and more susceptible to acne.
Why are genes not always accurate in describing behavior?
As genotype can be affected by environment and other factors, so that the phenotype is not always the same.
What are the four different neurotransmitters often used in the biological approach?
Oxytocin, Serotonin, Dopamine and Cortisol
What is the function of Oxytocin?
Oxytocin causes us to form bonds and relationships. Often caused by skin on skin contact or interactions with babies/baby animals. The chemical makeup of love can often be decoded by having large amounts of serotonin, dopamine and oxytocin.
What is the function of Serotonin?
Serotonin creates relaxation/ satisfaction. People with depression often lack this, as do people with insomnia and people with anxiety disorders. It is often released after we eat, which can also explain why people with binge eating disorder become addicted to eating.
What is the function of Dopamine?
Dopamine causes stress, but this is often pleasurable stress, that can be seen as drive or excitement. There is often an excess of Dopamine in people with anxiety disorders, OCD and anorexia nervosa. If we are born with the COMT gene ( a gene that aids the production of catechol-O-methyltransferase, COMT) you could have an excess of dopamine, as COMT regulates dopamine production.
What is the function of Cortisol?
Cortisol is the main stress hormone in the body. It enters cells (it can enter every type of cell) nad causes a release of sudden energy. It causes fight or flight, fear and anxiety, but because of its depletion of cell’s energy store, it causes aging and stress related illness (can also contribute to alzheimers).
What are four important principles of the BPS code of ethics?
Respect, Competence, Responsibility and Integrity.
What is the content of the principle of Respect in the BPS code of ethics.
It states that researchers must:
Respect the dignity and worth of all participants, which includes standards of privacy, confidentiality and informed consent. Intentional deception (lack of informed consent) is only acceptable when necessary for the integrity of the research and when the deception is revealed at the earliest opportunity. Participants should also be aware of their right to withdraw at any time.
What is the content of the principle of Competence in the BPS code of ethics.
Psychologists should maintain high standards in their professional work and the experiment should be designed well enough to have a good chance of wielding accurate or useful results. The experiment should therefore be designed with conduct validity in mind.
What is the content of the principle of Responsibility in the BPS code of ethics.
The researchers have a responsibility to their clients, general public and the science of psychology. This includes protecting participants from physical and psychological harm as well as debriefing at the end of their participation. Any harm extending beyond the experiment should be compensated for.
What is the content of the principle of Integrity in the BPS code of ethics.
Psychologist should record their findings honestly and accurately. This includes acknowledging any potential limitations. It also also includes bringing instances of misconduct to the attention of the BPS.
Name three key feature of the BPS code of conduct.
Informed Consent, Deception and Protection from harm.
Describe the key features of a laboratory experiment
- Takes place in highly controlled environments
- Researcher controls the independent variable and records/controls the dependant variable
- The experiments often have low mundane realism and ecological validity
Example = the stanford prison experiment
Describe the key features of a field experiment
- These experiments take place in a neutral, everyday setting
- Researcher manipulates the Independent variable and records the effect on the dependant variable (if there is any, the DV is not as controlled as in lab experiments)
-Often has good mundane realism, population validity and ecological validity as the experiment is usually with the general public or in a public place.
Example = That experiment where different races gender and minorities/stereotypes of people were lying in a town square, pretending to be in pain, and they observed how many (unknowing) participants helped the different confederates.
Describe the key features of a Quasi experiment
- can be considered not a true experiment
- The independent variable is based on an existing difference between the participants (e.g. age/gender), so therefor no one manipulates the independent variable, as having different ages and genders etc. in a sample occurs naturally
- Very common, an example would be the numerous studies completed to try and decipher whether men or women are more intelligent.
Describe the key features of a natural experiment
- The researcher takes advantage of a pre-existing independent variable
- Therefore, the independent variable is not controlled, it occurs naturally
- Often used when manipulating the independent variable is unethical
Describe or draw the table you use to remember whether the IV and/or DV are controlled in an experiment
IV DV

describe Pavlov’s experimental research
Pavlov is credited with discovering Classical Conditioning. He did this through experimentation involving dogs and their salivary reflex. He discovered how to turn a neutral stimulus into an cs by encouraging an conditioned response that was originally an unconditioned response to a priorly unconditioned response to and unconditioned stimulus. In this case, the neutral stimulus was the ringing of a bell, the unconditioned response was the dog salivating and the unconditioned stimulus being food. The neutral stimulus originally produced no salivation, while the food (UCS) did produce salivation. Pavlov then rung the bell every time he bought the animal food. The dog then began to salivate at the sound of the bell, meaning it became a conditioned stimulus.
describe Skinner’s experimental research
Skinner tested and theorised operant conditioning, using a lab experiment, testing on rats and using a special apparatus he created called Skinner’s box. This box was similar to a normal cage, with the defining factor being that it had a lever that revealed food when pushed. Skinner wanted to test whether or not and animal repeats behavior depending on whether the said behavior is reinforced or not. Skinner found that, once the rat discovered the lever led to food, it pushed it more and more often, until Skinner ran out. This showed how the food, being positive reinforcement, caused the rat to associate the behavior of pushing the lever with the positive sensation of eating (and the serotonin release that came after) so therefore caused the rat to repeat the behavior.
describe Bandura’s experimental research
Bandura conducted a lab experiment on children where he observed how social learning theory and imitation effected aggressive behavior. The study involved opportunity sampling and used an independent group design. In the experiment, the children were split into three groups, and every group was shown a video of an adult model behaving aggressively towards a popular kids doll (bobo doll). Each one-third group was either shown the model being rewarded, told off, or just walking away. Bandura then put each child individually in a room with a similar bobo doll and covertly observed which children showed the most aggression to the dool (the group who saw the model being rewarded). This was a follow up study, from when Bandura conducted the same method, but split the sample into two and showed half of the kids a model being-non aggressive and affectionate towards the doll. He then observed that hardly any of the children who saw their model’s non aggressive behavior - rather than the children who saw their model being aggressive to the doll- behaved aggressively to the doll.
What is an opportunity sample? What are its strengths and weaknesses?
An opportunity sample is a sample using the most convenient or available participant sample, i.e. the nearest group of participants who fit he criteria, or people who walk past you on the street. This is good as it is easy and takes considerably less time than other sampling methods. However, the sample is very susceptible to population bias.
What is a Random Sample? What are its strengths and weaknesses?
A sample gathered either through the lottery method (drawing names out of a hat) or random number table (blindly selecting numbered participants from a table) or a random number generator. The positives of this are that it is unbiased, however it takes time as it needs to have a list of the population being tested and the selection methods can also be time consuming.
What is a stratified Sample? What are its strengths and weaknesses?
When sampling, you split the population into relevant subgroups (strata) (e.g. boys or girls, or age groups) and participants are obtained from each of the different strata in proportion to their occurrence in the population. Selection from the strata is done using a random technique.
What is a Systematic Sample? What are its strengths and weaknesses?
When you use a predetermined system to select participants, such as selecting every nth person from a phonebook (where n = any number). This could be considered unbiased, but also be considered not truly unbiased as it is not truly random unless you use a randomized method to select the starting number/starting participant.
What is a Volunteer Sample? What are its strengths and weaknesses?
Usually advertised in a newspaper or on a noticeboard, often advertised in university campus with small compensation. Can cause volunteer bias.
Name three types of self report techniques
Questionnaires, A structured interview and an unstructured interview.
What is a structured interview?
A structured interview has pre-determined questions, it is essentially a questionnaire that is delivered face to face with no deviation from the original questions.
What is an unstructured interview?
Similar to a structured interview, except new questions are developed during the course of the interview, as well as the pre-determined questions. These additional questions are usually developed based on the answers given by the participant.
What are the three guiding principals when writing questions for questionnaires?
Clarity, Bias and Analysis (CBA 🤦♀️)
What does good clarity look like in a question on a questionnaire?
Questions need to be easy to understand. This means not asking questions that could have two meanings, uses of double negatives and double barrelled questions (questions that ask for two separate answer in one sentence).
What does Bias mean when referring to a good/bad question in a questionnaire?
A biased question might make the respondent more likely to give a particular answer. An example of specific bias that commonly occurs when answering questionnaires would be social desirability bias. This would involve the respondents giving answers in order to look more attractive, generous or generally nice, rather than being truthful. A well designed question would avoid this.
What does analysis mean in the context of creating a good or bad question for a questionnaire?
Questions need to be written so that the answers are easy to analyse. For instance, closed questions can be used to make the questionnaire easier to analyse. These involve only giving a few set answers that the respondent could give to a question, rather than an open question (I.e.what do you like most about your job?), which could give different answers from each participant and therefore give results that are hard to analyse and make inferences from. However, closed questions might give answers that don’t truly represent the respondents real thoughts and behavior.
What are four important factors for writing a good questionnaire?
Filler questions, Sequence for the questions, Sampling Technique and Pilot Study.
Why are filler questions important for writing a good questionnaire?
Filler questions can be used to include irrelevant topics to distract the respondent from the main purpose of the survey, therefore reducing the chances of demand characteristics (the Hawthorne and F.U. effect).
Why is the sequence of questions important in making a good survey?
It is best, during the questionnaire, to start with the easiest, saving the questions that are more pressing, so might cause feelings anxiety or a defensive attitude until the respondent has got used to the questioning and feels more comfortable.
Why is sampling technique important in creating a good questionnaire?
The sample used to select respondents, as different sub-groups, such as age and gender, could cause different results.
How would using a pilot study help in the creation if a good questionnaire?
By first testing a draft questionnaire on a smaller sample group, the questions can later be refined in response to any errors or difficulties observed in the pilot study.
What is the ethical issue of informed consent?
4 answers
+ Means the researchers have revealed the true aims of the study and the subject still participates.
+ Has drawbacks, knowing the hypothesis/aims can change the participants behavior
+ Considered a basic human right
+ Also involves researchers revealing any risks or benefits the study might cause (though these can be hard or impossible to predict)
What is the ethical issue of deception?
4 answers
+ Deception can be necessary in research studies when the participant knowing all details of the experiment could change their behavior, therefore affecting the results
+ Considered more reasonable to withhold some of the specifics of the study rather than deliberately giving the participant false information.
+ Can prevent the participant from giving informed consent.
+Could put people off future participation in studies or even psychologists altogether
What is the ethical issue involving the right to withdraw?
3 answers
+ Meaning that Participants know they can, and sometimes do, leave the study at any time
+ Can caused a biased sample for those remaining in the study as they are more likely to be obedient or to conform
+ can be compromised by paid experiments, as participants feel it is less acceptable to withdraw.
What is the ethical issue of protection from harm?
4 answers
+ More important studies tend to have higher risk of distress
+ Often difficult to predict any harm that may be caused, so protection can not be guaranteed.
+ Considered acceptable if the risk of harm is no higher than the risk of ordinary life
+ Also considered acceptable if the individual has been informed and agreed to the risk, or if they leave in roughly the study the same state they came in.
What does the ethical issue of confidentiality entail?
4 answers
+ May be compromised if the researcher wishes to publish the findings.
+ Can be supported by guarantee and use of anonymity, but a smaller target group could mean that the results can still be easily tracked back to individual participants.
+ The Data Protection Act (DPA) makes confidentiality a legal right
+ Recording of personal data is only acceptable if the data is not available in a form that could identify participants.
What does the ethical issue of privacy involve?
2 answers
+ Can be difficult to not invade privacy when studying participants without their awareness, i.e. in a field experiment
+Normal privacy should ideally be withheld (like having privacy in your own home) t maintain mundane realism.
How can you help to deal with issues of Informed Consent in an experiment?
3 answers
+Obtaining formal consent to the experiment and conformation of knowing the nature of, purpose of and their role in the experiment.
+ Could ask presumptive consent
+ Offering and exposing the right to withdraw
What is presumptive consent?
When a researcher asks a group of people who are similar to a participant if they would take part in this study, after revealing the aims and conditions fully. If the answer is yes, it is presumed the participant would give consent. This is useful if the study requires deception to obtain the required results or reduce demand characteristics.
How can a researcher deal with the ethical issue of deception in a study?
3 answers
+ The need for deception should be reviewed and approved by an ethics committee
+ Participants should be fully debriefed after the study, which involves revealing the studies true nature and allowing the participant to discuss any concerns this raises.
+ Participants should also be offered the option to withhold their data from the study
How can a researcher factor in the right to withdraw in their design of a study?
+ Participants should be informed of this right at the start of the study
How can researchers improve protection from harm within a study?
2 answers
+ Avoid any risks greater than those experienced in everyday life
+ Stop the study if harm is suspected
How can researchers factor in a participants privacy in an experimental study?
name one limitation to this
+ Not studying anyone without their consent unless it is public behavior performed in a public place (i.e. PDA in a park)
+ However, there is no universal agreement of what makes a public place
What is meta-analysis?
A researcher looking at all the findings and results from similar studies investigating similar aims and producing a statistic to represent the overall effect/result (i.e. saying a specific weight-loss programme causes on average 30kg weight loss, based on the effect in multiple individuals)
What is one strength of meta-analysis?
Can increase population validity, as the result is from a larger group of participants.
What is an unstructured observation like?
Include example
When the researcher records ALL relevant information, without much specification or system. This can be problematic, as it can lead to the researcher only recording easily visible or eye-catching information. These may not be the most necessary or relevant behaviors. An example o this might be recording everything a person with anxiety disorder disorder does in a day, in order to try and analyse anxiety disorders.
What is a structured observation like?
It is considered the preferable method of observation, as it uses various systems to organise observations. Two main ways to structure observations are to use Behavioral Categories and Sampling Procedures.
What are Behavioral Categories and how are they useful?
helps us to compartmentalise actions into small, specific behaviors. For example, when recording a baby, instead of just observing an entire day with them, observing categories such as smiling, crying, sleeping, making fists, drooling, screaming etc. Behavioral categories should be objective and explicit enough that the observer should not have to make inferences from it, cover all possible behaviors in that situation/action and be mutually exclusive, meaning only one occurs at a time.
What are sampling Behaviors?
What are 2 examples?
Used in an unstructured observation, when there is too much information to record every piece of continuous data observed.
Event sampling- counting the number of times a target action or behavior occurs in an individual or group.
Time Sampling- Recording behaviors in a given time frame (i.e. level 2 obvs at Highfield)
What is the difference between PET and fMRI scans?
PET scans give more information as it has colours. It involves putting radioactive dyes in the body, that allow different tissues to show up on camera. It costs around £2000 per brain scan.
fMRI scans are similar, but only cost £500 per scan , and are less informative.
How are Correlations useful in psychology?
Used to analyse two co-variables and their relationship with each other, used when it would be unethical to do an experiment and it wuld be impractical and/or impossible to control the variables.
What is the correlation coefficient?
A measurement of the strength and the direction of a correlation.
What is the figure for a Perfect negative correlation Coefficient?
-1.0
What is the figure for a Negative correlation Coefficient?
-0.5
What is the figure for no correlation Coefficient? (no correlation or relation)
0.0
What is the figure for a Positive correlation Coefficient?
+0.5
What is the figure for a Perfect correlation Coefficient?
+1.0
What are two examples of direct investigator effects?
+ when the researcher uses extraneous or confounding variable that change the behaviors/DV of the participants
+ If, during observation or an interview, an investigator shows enthusiasm for specific enthusiasm or delivers questions with varying enthusiasm
What are examples of Indirect Investigator Effects?
+ operationalizing variables in a way that makes the desired result more likely
+ limiting the duration of the study to make it easier to get the determined result
+ Keeping the standardised procedure not specific, leaving more room for the investigator to influence the results.
Name two ways to reduce investigator effects
+The single blind design- Keeping the participant unaware of research aims
+ The double blind design- both participant and investigator are kept unaware of aims.
What is a schema?
It is part of mediational processing. It helps us make decisions and process our surroundings, it is usually derived from past experiences.
Name the three types of experimental design
Repeated measures design, independent group design and matched pairs design
Describe independent group design
Participants allocated into two or more groups, one condition/IV tested on each group. Allocation usually done using random technique.
Describe matched pairs design
Participants are paired up based on matching or similar key variables. One person from each pair then completes the method with a different IV/condition.
Describe Matched Pairs Design
Each participant takes part in each condition sequentially.
What are the two features of the central nervous system?
The brain and the Spinal Chord.
What does the Peripheral Nervous System control?
It is responsible for receiving and sending sensory signals.
For example emotional responses and unconscious sensory experiences such as sleeping and digestion.
What are the two features of the Peripheral Nervous System?
The Somatic Nervous System and the Autonomic Nervous System.
What are the two features of the Autonomic Nervous System?
The Sympathetic and the Parasympathetic Nervous System.
Name 5 features of the Sympathetic Nervous System
+ Associated with fight or flight
+ Involves releasing Cortisol, Adrenaline and Noradrenaline
+ Increases Heart rate
+ Inhibits saliva Production (dry mouth)
+ Stimulates glucose production and urination
Name 5 features of the Parasympathetic Nervous System
+ Associated with sleep, digestion and unconscious responses
+ Increases rate of digestion
+ Increases saliva production
+ Decreases Heart rate
+ Antagonistic with the Somatic Nervous System, meaning they can’t work at the same time as they can’t work at the same time.
What is the role of Adrenaline?
Causes the fight or flight response, only affects muscles.
What is the role of Noradrenaline?
Causes concentration, also released in fight or flight (like before an exam), main difference from adrenaline being that it affects the brain and not muscles.
What is the role of Gaba?
Neurotransmitter responsible for calming brain function and emotion. Does this by cutting of neurons, it is the neurotransmitter that benzodiazepines triggers to relieve stress and anxiety.
What is the role of Acetylcholine?
The learning neurotransmitter, it stimulates new growth in the brain. Often too high in people with ADHD.
What is the role of Glutamate?
The neurotransmitter responsible for memory. Often released with dopamine to create happy memories.
What is the role of Endorphins?
Creates a feeling of euphoria, also reduces perception of pain. Often released during exercise.
What are the neurotransmitter imbalances associated with Parkinson’s disorder?
Very low dopamine levels.
What are the neurotransmitter imbalances associated with Anxiety disorders?
Overly high noradrenaline and dopamine, with uncontrolled or low serotonin. Often similar to the imbalances characterised in major depression.
What are the neurotransmitter imbalances associated with Aggression (IED)?
Low serotonin and GABA (characterising a stressed and overactive brain), with high cortisol and dopamine causing a lot of fight or flight and panic. Very similar with the imbalances in those with schizophrenia, often why people with schizophrenia show signs of are more susceptible to, or are associated with aggression.
Name 5 hormones released by the pituitary gland and their functions
+ Vasopressin- responsible for water retention, often causes the stimulation of urination during fight or flight response
+ Gonadotropin- aids the growth of hair and the production of milk in lactating mothers.
+ Oxytocin- responsible for orgasm, attachment, infatuation and parental bonding.
+ Melanin- aids tanning and complexion
+ Cortisol- responsible for stress.
What are the two parts of the adrenal gland?
The Adrenal Cortex and the Adrenal Medulla
What is the role of the Adrenal Cortex?
It is necessary to live, it triggers the release of cortisol and aldosterone.
What is the role of the Adrenal Cortex?
It is necessary to live, it triggers the release of cortisol and aldosterone.
What is the role of the Aldosterone?
Regulates sodium absorption, therefore regulating salt and water levels. It is considered a steroid, so therefore can be converted into other steroids, such as Progesterone and Testosterone.
What is the role of the Adrenal Medulla?
It is not technically necessary to live. it releases adrenaline and noradrenaline, meaning it controls triggering the fight or flight symptoms.
Where is the Adrenal Gland located in the body?
Just above the kidneys.
What emotional response is triggered by progesterone?
Causes feelings of stress and feelings of threat ( main cause of Premenstrual stress, as that is when progesterone is at its highest).
What emotional response is triggered by Oestrogen?
Causes relaxation and helps production of collagen (often improves complexion).
What emotional response is triggered by Testosterone?
Causes male characteristics ( whatever the fuck those are), sex drive, work drive, muscle growth. Can be associated with aggression or pugnaciousness.
What are the three most important types of neuron?
Sensory, motor and relay neurons
What are 5 features of a Motor Neuron?
- They are part of the Somatic Nervous System (conscious response)
- form synapses with muscles
- when viewed during a dissection, they are part of the pink tissue in the brain ( part of the grey matter)
- Controls muscular contractions (as of the synapses it forms) by releasing certain neuro transmitters (such as nor adrenaline)
- Muscle relaxation is cause by the inhibition of this neuron
What are 5 main features of Sensory Neurons ?
- carry nerve impulses from sensory receptors (e.g. receptors for vision, taste, touch, smell)
- carry impulses from sensory receptors to the brain and spinal chord (the central nervous system)
- Sensory receptors are found all over the body, like in eyes, ears, tongue and skin, so sensory neurons travel all round the body
- Also found in the grey matter (the tissue that looks pink in a dissected brain)
What are 5 features of a Relay Neuron?
- They are mostly found in the spinal chord
- they are characterised for transmitting information
- They help sensory and motor neuron communicate with each other
- They are part of the white, spindly tissue we see in a dissected brain.
- they are part of the autonomic (non conscious) nervous system
What is action potential and what is its role in synaptic transmission?
Action potential is the electrical signal that moves through nerves. It can be detected in an MRI scan. At the synapse, action potential is transmitted into neurotransmitters.
What is a vesicle and what is its role in synaptic transmission?
A vesicle is a bubble like feature carries neurotransmitters and signals through the synapse. Specifically, it encased the neurotransmitters when they are travelling through the postsymaptic cell, but releases the neurotransmitter when it meets the cell membrane before the synaptic gap, as both the vesicles and the membrane are made of similar fats, so they amalgamate and break down the vesicle during contact.
What are the Neurotransmitters and what is their role in synaptic transmission?
Neurotransmitters diffuse across the synaptic gap to bind to the receptors and create a response.
What is the synaptic gap and what is its role in synaptic transmission?
The synaptic gap is the gap between the pre synaptic cell and the post synaptic cell. It is what neurotransmitters diffuse across. They can release multiple neurotransmitters, and is the feature in synaptic transmission, that turns active potential into neurotransmitters
What is a receptor and what is its role in synaptic transmission?
Receptors are found in the post synaptic cell, after the synaptic gap. They are what receptors diffuse to in the reaction. They are where the neurotransmitters are interpreted, and are used to decide how the neurons react (if there is a physical, mental or other response - what neurons are released). They are also important, as they help decide if a excitatory response or inhibitory response is produced via summation. It does this as all receptors are neutral, but will change to have a positive or negative charge, depending on whether they recieve an excitatory or inhibitory response.
What are post synaptic potentials and what are the two types?
Like active potential, but occurs after the synapse and causes a response by causing a neuron to send a signal to the brain, which usually creates a response. It can either be excitatory or inhibitory.
What are excitatory neurotransmitters?
They cause an active response, or a response that encourages a reaction/behavior, rather than reducing it. Examples would be Noradrenaline, adrenaline and acetylcholine. These trigger learning (via new tissue growth in the brain) and fight-or-flight fear responses.
What are inhibitory neurotransmitters (give two examples).
These neurotransmitters decrease the likelihood of electrical impulses (post synaptic responses) firing, so they often calm/slow down brain function. They also often stop a reaction or behavior. Examples of this would be GABA or serotonin (GABA is found in benzodiazepines and slow nearly all brain functions, and serotonin causes us to feel relaxed and happy)
How does summation determine whether a post synaptic potential is positive or negative?
Receptors are neutral, but take in a positive or negative charge if they are effected by a excitatory or inhibitory neurotransmitter. The sum of these receptors controls the response , I.e. if there are more positive receptors the post synaptic potential and response will be excitatory and if there are more negative receptors the post synaptic potential will be inhibitory.
What is the role of dendrites in a neuron?
They recieve signals from other neurons or sensory receptors and then relay impulses to the rest of the neuron. They are connected to the cell body.
What role does the cell body have in a neuron?
The cell body is the control centre of the neuron, it is where the neurons are received before they are projected along the axons.
What role does the myelin sheath play in a neuron?
The myelin sheath encases the axons that are carrying the impulses. It insulates the axons as they are made of fats. They are wrapped around the axons in small sections called schwann’s cells. The break down of the myelin sheath can cause neurological diseases such as Multiple sclerosis.
What role do nodes (of ranviers) play in neurons?
They are the parts of the axons that stick out from between the schwann’s cells. These are what new cell bodies in neuron cells are grown from.
What are terminals in a neuron?
What the impulses are related to via the axon.
What is positive reinforcement?
when the person is presented with a motivating/reinforcing stimulus after the desired behavior is completed. Giving your child £1 if they get a good school report.
What is negative reinforcement?
When an unpleasant (aversive) stimulus is removed after a behavior is exhibited, encouraging the person to repeat the behavior. for example, a boy doing the dishes so his mother doesn’t shout at him.
What is positive punishment?
When an unpleasant/aversive consequence is presented when an undesired consequence is completed. for example, if someone touches a hot stove and feels pain.
What is Negative Punishment?
When a certain reinforcing stimulus is removed after an undesired behavior. A child acts out, and their favourite toy is taken away.
What are the three types conformity?
conformity, internalisation and identification
What are 5 features of Compliance?
- It was identified by Kelman in 1958
- characterised by the individual copying the behavior, despite disagreeing with the basis of said behavior
- often seen in cases of peer pressure/totalitarian or dictatorship countries
- there is no change in the individual’s internal/private attitude or personality, they just imitate the behavior
- compliance is only really expressed in public, or while in a group
Name 5 features of Identification conformity
- discovered by Kelman in 1958
- the individual does not originally agree with the behavior, but is later convinced/cajoled into agreeing with the basis of the behavior by another person/informant
- the person therefore completes their behavior from their own will, but only after being convinced to change their mindset
- often the cause if conformity is that the person conforms to feel part of a group, derived by a desire to fit in
- An example could be a kid starting smoking to fit in with the smokers, or someone becoming a jehovah’s witness after being door-to-door visited.
What are 5 features of internalisation?
- discovered by Kelman in 1958
- it involves copying a behavior as it fits your internalised, subconscious or conscientious viewpoint
- relies on having matching views as others who express this through certain behaviours, so therefore completing similar behaviours as you have similar views
- you usually agree with the behavior (I.e., the behavior does not seem immoral or unjust to you)
- an example would be political campaigns, such as the climate strike
What is conformity?
Conformity is a type of social influence where beliefs and/or behaviours of an individual change to fit with a group. This is usually down to pressure from the group, though group pressure can be real or imagined.
What are the two types of social influence?
Normative social influence and informational social influence.
What is normative social influence?
An influence that causes you to conform ad you wish to be more normal/fit in or be correct. It is often driven by a need for social companionship and a fear of rejection. In order for this to occur, the individual must feel like they are being watched or closely surveyed by the group (expressed public behavior). Compliance is usually caused by Normative Social Influence.
What is informational social influence?
Causes a person to conform to carrying out a behavior, but only after they have been given informational evidence that this behavior is best. It is often driven by a desire to be validated and have your beliefs be correct. Internalisation is an example of informational social influence, as -even though your beliefs and views are never opposed to the behavior- you have to be convinced to complete the behavior with relevant information.
How did Sherif study conformity? (Give method)
- (in a small sample) Sherif told the participants he was testing on that he was studying auto kinetic effect the idea that if you stare at something for long enough, it will appear to be moving
- participants were told a light would travel and that they should guess how far it travelled
- They were then placed in a dark room and observed the said light
- they then stated their estimates in groups of 3. Sherif found that the third participant always estimated the distance between the first and third participants.
What was the purpose of Asch’s experiment?
Designed to show that people do not make their own decisions (debunking the idea of free will).
Give a basic outline of the method in Asch’s experiment.
- (of a sample) participants all sit together in one room
- each participant reports, in turn, out of three different length lines, which is closest in length to another line given, that they call the standard line.
- only one of the men was a real participant, the rest were confederates
- the confederates all deliberately gave wrong/verifying answers.
- Asch then recorded how many participants changed their answer in order to conform.
Give a basic outline of the results in Asch’s experiment.
After all his fellow “participants” gave their false answers, 75% of participants gave the wrong answer to conform at least once, and a third of people gave the wrong answer/copied the confederates’ answers for the entire experiment. Asch believed that this was an example of if compliance due to normative social influence.
How big was the sample used in Asch’s experiment?
The sample consisted of 123 Male US undergraduates, which were split into smaller groups for testing.
What is autonomous state in relation to Situational expectations of obedience?
The state you are in when your actions are under your own control, you are in this state in normal everyday freedom.
What is agentic state in relation to Situational expectations of obedience?
The state you are in when you have deferred responsibility to someone else (i.e. following orders)
What is agentic shift in relation to Situational expectations of obedience?
The point at which you lose sense of responsibility (i.e. the point at which you submit to following orders).
What is legitimacy of Authority in relation to Situational expectations of obedience?
Whether or not a person giving orders has features associated with authority that make us obey them.
What was the hypothesis of Milgram’s experiment?
Good natured, everyday civilians are just as likely as anyone else to perform harmful acts, as long as they are told to by a position of authority (when they are in an Agentic State)
What was the operationalised hypothesis of Milgram’s experiment?
Whether or not people will deliver harmful or even lethal electric shocks to another person, if they are told to do so by a person in a position of authority
How many participants were there in Milgram’s first experiment?
40 participants
How many confederates were there in each participant’s individual test in the Milgram experiment?
There were 2 confederates in every condition- an “experimenter” ( a person in a white coat who ordered the participant to administer the electric shocks) and the “participant” who was assigned the role of learner, so therefore answered questions and pretended to receive painful shocks over loudspeaker through vocal acting.
In Milgram’s experiment, what was the ACTUAL participant asked to do?
The participant was asked to ask a fellow participant (who was actually a confederate) a series of questioned over a telephone line, and to shock them if they got the answer wrong. The number of volts increased as the participant continued to ask questions, until the participant was being asked to deliver a lethal dose (and by 300 volts, the confederate would usually verbally object and request for the participant to cease the shocks.)
What were Milgram’s findings?
65% of the 40 participants (26) continued to deliver shocks to the “learner” until they reached the maximum voltage, 450 volts. Only 5 participants stopped at 300 volts, when the confederate would have pretended to object and request the participant to stop the shocks.
What 3 situational factors did Milgram find to affect obedience?
Proximity, Location and The power of uniform
How did Milgram modify his original study to observe the effects of proximity on the results?
The study was repeated with a similar manner, but the learner and the teacher were in the same room. Obedience levels were 30% less than the study before (now only 35% obeyed)
How did Milgram FURTHER modify his original study to observe the effects of proximity on the results, to this time involve direct contact?
The study was repeated, but this time the participant had to hold the confederate’s hand to a “shock plate”, and obedience therefore dropped to only 30% of people obeying.
How did Milgram EVEN FURTHER modify his original study to observe the effects of proximity on the results, to this time involve authority absence?
The study was repeated, but the experimenter confederate giving the order to shock the learner over the phone. This study resulted in the majority defying obedience, with only 21% of participants delivering the maximum shock.
How did Milgram reshape his study to target the limiting factor of location?
The study was originally located in Yale University, which apparently gave participants the idea that the shocks couldn’t be real and/or harmful, or that the study must have been legitimate, which would have increased levels of obedience. Milgram therefore repeated the experiment in a less trusted/prestiegeous location (a ran down office far away from the university). Though obedience levels dropped slightly, 48% of participants still administered the maximum 450 v shock.
How does uniform affect obedience to orders? Briefly outline one study that proves this
Uniforms have been shown to associated with power and authority, so a person wearing a uniform may see to have more legitimacy of authority, so a uniform could increase the chances of obedience. An example of this would be Bushman’s study in 1988, when a confederate dressed in many different uniforms stopped random stranger on the street and asked them for change. When the confederate was in uniform, 72% obeyed, when dressed as a beggar 52% obeyed, and when dressed as a business executive, 48% obeyed.
What historical event inspired Mirams study into situational explanations of Obedience?
Milgram was inspired by the media’s televising of the trials of some German Leaders involved in WW2, specifically a man named Eichman, who was partly responsible for the idea/use of death camps for jews in Auschwitz and Birkenau. Eichman, claimed that the soldiers were “Just following orders” and “didn’t understand what they were doing”. Many of the British public believed that Germans were evil, but Milgram believed they were just subject to unfortunate circumstance and situational pressure, hence the study.
