Q

What does the underlying philosophical approach of the BPS code of ethics and conduct mean for psychologists actually carrying out research on human participants?

A
  • Ensure safety of human participants so no harm is done
  • Maintain high standards of confidentiality because if they wouldn’t like it done to themselves, they shouldn’t do it to others

Q

What are the advantages of following ethical guidelines when carrying out psychological research on humans?

A
  • Society’s moral standards are maintained - psychologists must adhere to professional values if society is to see their research as having credibility + status
  • Ps protected from physical harm
  • Maintains reputation of the discipline + profession
  • Ethical problems in study won’t get in the way of research being replicated

Q

What are the disadvantages of following ethical guidelines when carrying out psychological research on humans?

A
  • Understanding of human behaviour is restricted - as can’t do covert observation of private behaviour that’s behind closed doors which reveals darker side of human behaviour
  • Difficult to study extreme behaviours or controversial topics - so credibility of psychological research findings may be lowered
  • Ethical guidelines constrain research in psychology and therefore reduce its validity

Q

What are the reasons why animals should be used in psychological research?

A
  • Research is highly reliable because of well controlled standardised lab experiments which are easily replication - animals are good participants
  • Similar to humans in brain structure + neurotransmitters as humans

Q

What are the Ethical Reasons for Conducting Animal Research in Psychology?

A
  • Many experiments are unethical for human testing, but important enough to be justified for animal testing
  • Van den Oever (2008) - trained rats to self-administer heroin + found that there were changes in their neurones in the prefrontal cortex which made them more likely to seek the drug again - he concluded that the medial PFC could be a potential target for therapeutic drugs to reduce relapse in heroin addicts

Q

What are the Similarities to Humans as a Reason for Conducting Animal Research in Psychology?

A
  • Humans are more complex animals - so, easier to study more simple organisms first then generalise to humans
  • Animals + humans both have brain structure + neurotransmitters are similar
  • But, animals aren’t similar enough to humans - animals have different genetic structure + different balance in senses so perceive world differently
  • Also, human behaviour is more complex + they have different motivations + have superior cognitive abilities (e.g. self-awareness)

Q

What are Animals are Good Participants as a Reason for Conducting Animal Research in Psychology?

A
  • They’re more controllable
  • Research w/ them is highly reliable as they use standardised lab experiments which are easily replicated
  • Faster breeding cycles allow test to be conducted on the influence of heredity + environment on behaviour - providing useful evidence for the ongoing nature nurture debate

Q

What are 2 Reasons Why Animals Shouldn’t be used in Psychological Research?

A
  • Ethical reasons - animals harmed during research, e.g. boredom, pain
  • Practical reasons - Animals aren’t similar enough to humans to ensure research allows valid generalisation to humans = animals have different balance in senses so perceive the world differently + they have different genetic structure to humans

Q

What is the Scientific Method?

A
  • The process of testing hypotheses which have been derived from theories that are tested in objective scientific ways
  • The resulting data is tested for reliability + is used to verify or falsify the original theories
76
Q

What is Empiricism?

A

•An emphasis on those aspects of scientific knowledge that
are gained from direct experience
•All hypotheses + theories must be tested against direct observations of the nature (real) world

77
Q

What is Falsification?

A

•The idea that we can only truly
prove something is not the case
•The act of providing empirical evidence that a theory or hypothesis is false or incorrect

78
Q

What is Science Defined as?

A

The systematic study of the world based on observation, experiment and measurement

79
Q

What are the Characteristics of Science?

A
  • Knowledge should be empirical
  • Knowledge should be falsifiable
  • Knowledge should be replicable + reliable
  • Science also tends to be reductionist
80
Q

What is Reductionism?

A

It’s more useful to study these phenomena by breaking them down into their component parts + study each of their parts separately

81
Q

What is Holism?

A

To study something in its entirety, as a whole is a more meaningful form of research

82
Q

What are the Arguments Supporting Psychology as a Science?

A
  • Psychology uses scientific research methods such as the use of the experimental method
  • Much research in psychology is replicable + reliable due to the use of standardisation, even in non-experimental methods
  • Psychology has falsifiable theories that generate hypotheses which can be tested
  • Scientific reductionism is a widespread viewpoint in psychology
83
Q

What are the Arguments Against the Idea that Psychology is a Science?

A
  • Psychology is not empirical as much of the subject matter that psychology is interested in is not directly observable
  • Psychology often uses research methods that aren’t considered scientific
  • Psychology cannot be an objective research discipline so it cannot be a science
  • Theories + explanations often not falsifiable because of the subject matter of human behaviour
  • Research can often lack reliability as studies can be restricted to specific times in places
84
Q

What is the Test-Retest Method?

A
  • Group of participants complete a test twice at different times
  • The 1st and 2nd scores are correlated + a high positive correlation means that the test produces reliable outcomes
85
Q

What is the Split-Half Method?

A
  • Measures extent to which the different items on the test are measuring consistently
  • Ps take test once, scores on 1 half of the test are compared w/ their scores on the other half of the test
  • High correlation indicates the test items are equivalent + consistent in the way they are measuring the variables of interest
86
Q

What is a Correlational Research?

A

Investigates the extent to which two variables are associated showing a trend or systematic pattern linking them

87
Q

What are Co-Variables?

A

Two variables in a correlational study which have been measured

88
Q

Q

What are Strengths of Correlational Research?

A
  • If a relationship between two variables is indicated this can be a starting point for stimulating future research
  • It allows the identification of relationships between variables when it is difficult for practical reasons or unethical to manipulate the variables the researcher is interested in
  • Correlational research is scientific in that it tends to be objective + easily replicable using quantitative data collection methods
103
Q

What are Weaknesses of Correlational Research?

A
  • There is little control over variables so it doesn’t allow cause-and-effect links to be established
  • Correlations can be misused - it is difficult to make accurate conclusions about the causes of relationship - Scientist + Media make huge claims based on correlational research that sounds convincing to the public but in reality it could mean something different
104
Q

A

Focuses on the observation of a persons freely chosen behaviour

105
Q

What are the 2 Main Types of Observational Research Methods?

A

  • Collecting qualitative data
  • Behaviour is studied in its natural setting + environment left as it normally is
113
Q

What are the Advantages of Naturalistic Observations?

A
  • Useful for the study of behaviour in situations where ethical considerations prevent manipulation of variables
  • High ecological validity as setting is natural, so the results are more generalisable to real life behaviour
  • Data is very rich, detailed + meaningful = validity increased as naturalistic observations can gather data on all that happens in real life situation
114
Q

What are the Disadvantages of Naturalistic Observations?

A
  • Low reliability - replication of naturalistic observations is more difficult
  • Lack of control over extraneous variables means that cause-and-effect relationships between variables cannot be established
  • Threat to validity - People may become aware that they are being studied + alter their behaviour
  • Ethical considerations concerning deception, consent + invasion of privacy + right to withdraw can be serious issues
115
Q

What are the Main Characteristics of Structured Observations?

A
  • Non-participant observations
  • Collecting quantitative data
  • Covert = observer remains discreet (e.g. using screens)
  • Involves recording of spontaneously occurring behaviour (by film/tape)
  • Some of variables (including environment) are controlled
  • Situations may be set up or structured in some way
116
Q

What are the Advantages of Structured Observations?

A
  • Higher reliability - there is greater control which leads to easier replication
  • More control over the environment which leads to more accurate observations as highly standardised procedures put in place
  • Control confounding variables
117
Q

What are the Disadvantages of Structured Observations?

A
  • Cannot attribute causality between IV + DV as there may be problems controlling variables
  • IV hasn’t been manipulated in the same way
  • Low ecological validity - because if in a Lab then non-natural behaviour + recorded in structured categories (artificial)
118
Q

What are the Advantages of Participant Observations?

A
  • High ecological validity - people continue normally

* More meaningful observations as observer has better understanding of events = richer + more detailed data

119
Q

What are the Disadvantages of Participant Observations?

A
  • Ethical issues raised - deception + invasion of privacy is a problem
  • Researchers may get too involved - become less objective - influence natural behaviour of the group which affects validity
  • Difficult to record observations of behaviour at the time it happens - info may be forgotten but can use hidden cameras to help + data is prone to bias as the researcher is interpreting it
120
Q

What are the Disadvantages of Non-Participant Observations?

A
  • Validity lowered - as non-participant observer has little understanding of what is happening
  • Ethical issues (invasion of privacy, consent, right to withdraw) are raised
121
Q

What are the Advantages of Non-Participant Observations?

A
  • Objectivity higher - as the observer has no stake in the activities being observed
  • Accuracy of observations + amount of data collected is high - observer focuses on data collection - so, validity is high
122
Q

What are the Advantages of Covert Observations?

A
  • Higher validity - behaviour more natural
  • Demand characteristics lower as observer can record data without being concerned about the effect it will have on participants
123
Q

What are the Disadvantages of Covert Observations?

A
  • Ethical issues raised - difficult to gain consent, debriefing, deception, no right to withdraw, invasion of privacy
  • Practical problems - not easy to observe behaviour secretly as difficult to find a position where notes are being made
124
Q

What are the Advantages of Overt Observations?

A

Ethical - can gain consent, debrief - a good place to observe can be chosen + discussed

125
Q

What are the Disadvantages of Overt Observations?

A
  • Observer may be distracted, so data recorded may not be that accurate
  • Behaviour may change - increased effects of demand characteristics, social desirability
126
Q

What are the Issues in Observational Research?

A
  • Reliability - researcher effects can lead to low inter-observer reliability
  • Observations lack validity if the coding systems are flawed or vague
  • Validity of observations are affected by researcher bias as the way they record their observations is subjective
  • Subjective interpreters of behaviour by observers must be avoided
  • Ethical issues - no informed consent, no debriefing, invasion of privacy
127
Q

How do you Deal with Threats to Validity in Observational Research?

A
  • The behaviour to be observed must be clearly operationalised
  • Behaviour checklists must be carefully planned + piloted to ensure they measure what was originally intended
  • Using more than one observer + conducting observations in varied settings will reduce observer bias
128
Q

How do you Deal with Threats to Reliability in Observational Research?

A
  • Pilot studies can be used to train observers in the use of the recording systems
  • Eventually their observations should show a high positive correlation when tested + high inter-observer reliability

133
Q

When is Continuous Observation Useful as a Technique for Sampling the Behaviour of Interest in Observational Research?

A

If the behaviour of interest doesn’t occur very often

134
Q

What are the Advantages of Time Sampling as a Technique for Sampling the Behaviour of Interest in Observational Research?

A
  • Reduces the amount of time spent in observing behaviour

* This may reduce boredom + fatigue in observers which increases their accuracy

135
Q

What are the Disadvantages of Time Sampling as a Technique for Sampling the Behaviour of Interest in Observational Research?

A

Certain important instances of the target behaviour may be missed unless sampling is carefully planned

136
Q

What are the Advantages of Event Sampling as a Technique for Sampling the Behaviour of Interest in Observational Research?

A
  • It limits the behaviours that need to be observed so it reduces the chance that the behaviour of interest will be missed
  • Quantitative - quick + easy
  • Objective - not stating any of your own behaviour
137
Q

What are the Disadvantages of Event Sampling as a Technique for Sampling the Behaviour of Interest in Observational Research?

A
  • It may be difficult to observe all events if there are a large number of people to observe or if they are spread over a large area

A

Any psychological research that has ethical implications that go beyond the research situation + affect people or groups in the wider society

150
Q

What are the Strengths of Content Analysis?

A
  • Very useful for analysing historical material
  • Reliability high - replication is easy as the materials + standardise procedures are available for others to use
  • No ethical issues but it may be socially sensitive as some topics have a -ve impact
  • High external validity - you’re investigating something that is actually seen/read/heard by people in the real world which increases the generalisability of the conclusions
  • Summarising qualitative into quantitative data is useful as it is a method of changing the mass of qualitative data + human communication into quantitative data that can be statistically analysed
151
Q

What are the Weaknesses of Content Analysis?

A
  • Low validity - subjectivity + researcher effects are high as the codes + categories are chosen by the researcher
  • Cannot show cause-and-effect-doesn’t reveal underlying motives for the observed patterns-e.g. doesn’t say why
  • Analysis may be limited by an unrepresentative sample of available materials - catastrophic events receive more coverage than less dramatic occurrences
152
Q

What is Thematic Analysis?

A

A technique used for the analysis of qualitative data-identifying + assessing patterns in qualitative data allowing conclusions to be drawn

153
Q

What are the Strengths of Thematic Analysis?

A
  • Data is rich + qualitative when identifying themes - provides ‘an intimate window onto life worlds of people’
  • Validity remains as data remains qualitative + main meanings in data should be preserved - large qualitative to manageable summery
154
Q

What are the Weaknesses of Thematic Analysis?

  • Results of experimental tasks carried out by the participant
  • Physiological measures - e.g. MRI scans
157
Q

What is the Purpose of a Case Study?

A
  • Gain in-depth highly detailed info

* Unique/valuable examples of human behaviour providing important insights into psychological functions

158
Q

What are the Advantages of Case Studies?

A
  • Collect rich + detailed data - often qualitative data
  • The data case studies provide trigger further research + can sometimes be used to challenge established theories as they deal with usual cases normally
159
Q

What are the Disadvantages of Case Studies?

A
  • Ethical issues are raised - e.g. invasion of privacy
  • Cannot be used to establish cause+effect links between variables due to lack of control over variables
  • Reliability is low - studies are often difficult to replicate as they are unique studies
  • Low validity - if participant’s being asked to remember info from the past which they may not recall correctly
  • Low validity - researcher spend a lot of time interviewing + building up a relationship w/ Ps leading to the researcher interpreting data in a subjective manner
160
Q

What is a Twin Study?

A

Comparing monozygotic twins + dizygotic twins pairs - comparing concordance rates

161
Q

What are the Strengths of Twin Studies?

A

Provide the only ethical way of studying the behaviour of people who are 100% genetically identical to see how much of a role DNA has in our behaviour

162
Q

What are the Weaknesses of Twin Studies?

A
  • No twin study has ever found 100% concordance rates on any characteristic or behaviour in MZ twins - so researchers must take into account the effect of the environment on behaviour - e.g. social class, poverty, etc
  • Low validity - researchers aren’t really measuring genetic similarities alone as MZ twins, being identical, may be treated more alike than DZ twins, so the higher concordance rates in MZs May also be due to the greater similarities in their upbringing than DZ twins
163
Q

What is an Adoption Study?

A
  • Look at the impact of nurture on children who are raised by parents who aren’t their biological parents
  • Compare the concordance rates
164
Q

What are the Strengths of Adoption Studies?

A
  • Allow the study of children where the influence of just the genetic influence of their biological parents can be studied as they have been from the influence of their upbringing
  • This cannot be done ethically in any other way
165
Q

What are the Weaknesses of Adoption Studies?

A
  • Only certain types of family might be accepted to adopt children w/ certain qualities - so results of research are less generalisable to the population
  • Children placed in adoptive families similar to their biological family - so researcher can’t assume that the 2 environments are very different - so, behaviour being studied may be transmitted from 1 generation to the next by social learning or reinforcement of antisocial values rather than genetics
166
Q

What are Concordance Rates in Twin Studies?

A

The degree to which members of a twin pair display the same characteristics, expressed as a percentage

167
Q

What are the Brain Scanning Techniques?

A
  • fMRI Scans
  • CAT Scans
  • PET Scans
168
Q

What does fMRI Scans Stand for as a Brain Scanning Technique?

A

Functional magnetic resonance imaging scans

169
Q

How do fMRI Scans Work as a Brain Scanning Techniques?

A
  • Detects changes in blood oxygenation + flow that occur in response to neural activity
  • Magnetic field produced by passing an electric current through wire coils
  • Magnetic field causes molecules within the body to move in a different way + release radio waves which the scanner detects
  • It detects the rate at which oxyhaemoglobin becomes deoxyhaemoglobin - this technique is called BOLD
170
Q

What is BOLD Contrast Imagine in fMRI Scans?

A
  • Blood oxygen level dependent

* Detects the rate at which oxyhaemoglobin becomes deoxyhemoglobin

171
Q

What happens to the Blood Flow of the Brain when a Specific Area is More Active in fMRI Scans?

A

•Increasing bloodflow w/ oxyhaemoglobin to that area •As, this area of the brain will need more oxygen to support the metabolic activity in the neurons

172
Q

How is fMRI Scanning used to Investigate Human Behaviour?

A

Cognitive tasks carried out by participant + brain areas in use are clearly identified in the images

173
Q

What does it mean if a Particular Area in the Brain has a High BOLD Contrast during a Specific Behaviour in fMRI Scans?

A

It can be inferred that the specific area has a role in producing the behaviour

174
Q

What are the Strengths of the Use of fMRI Scanning in Psychological Research?

A
  • Ethical - doesn’t involve exposure to radiation, so it’s safe for participants
  • Valid way of studying normal brain function for psychologists
  • It’s provided new insight to the investigation of how memories are formed, language, pain, learning + emotion and it’s being applied in clinical psychology settings
175
Q

What are the Weaknesses of the Use of fMRI Scanning in Psychological Research?

A
  • Cannot look at the activity of the actual receptors of neurotransmitters
  • Low Validity- images need to be analysed + interpreted, so misinterpretation is possible
  • High quality images are assured only if participants are able to remain perfectly still
  • Implanted medical devices that contain metal may malfunction or cause problems during an MRI exam
176
Q

How can CAT Scans be Used to Investigate Human Behaviour?

A

When investigating abnormal behaviour - CAT scans detect any structural abnormalities which you can associate with the behaviour

177
Q

How do CAT Scans Work as a Brain Scanning Techniques?

A
  • Use x-rays to build up a 3D structural image of the brain
  • Detectors measure amount of radiation being absorbed throughout brain
  • Detectors rotated to give views from a variety of directions
  • Many images combined by computer to give a composite detailed 3D image of the brain
178
Q

How can PET Scans be Used to Investigate Human Behaviour?

A
  • Participants scanned while completing cognitive tasks

* Find out which areas of the brain are active during specific behaviours

179
Q

How do PET Scans Work as a Brain Scanning Techniques?

A
  • Small amount of radioactive material injected into Ps
  • Radioactive material binds to glucose molecules in body, forming a tracer
  • Brain uses glucose as energy, so most active areas of brain absorbs the tracer
  • Radioactive material emits positively charged particles (positrons) which are picked up by the scanner
  • This info allows the computer to produce coloured images of the level of activity occurring throughout the brain
180
Q

What can CAT Scanning of the Head be Used to Detect?

A
  • Brain tumours
  • Enlarged brain cavities in patients with hydrocephalus
  • Diseases or malformations of the skull
  • Bleeding, brain injury + skull fractures in patients w/ head injuries
181
Q

What are the Strengths of the Use of CAT Scanning in Psychological Research?

A
  • Less harmful, not painful + it’s non-invasive
  • Provides very detailed images of the physical structures of the brain which is highly valid data
  • Less sensitive to patient movement
  • Can be performed if you have an implanted medical device of any kind
182
Q

What are the Weaknesses of the Use of CAT Scanning in Psychological Research?

A
  • Always a slight chance of cancer from excessive exposure to radiation but the risk is small
  • The precise details of soft tissue in the brain are less visible
183
Q

What are the Strengths of the Use of PET Scanning in Psychological Research?

A
  • High reliability - as they can be replicated exactly + same results are found
  • Gives valid measures of important functions in the brain such as bloodflow, O2 use + glucose metabolism providing unique data
  • Usually painless
184
Q

What are the Weaknesses of the Use of PET Scanning in Psychological Research?

A
  • Low validity - produce complex images that may be open to bias or error in interpretation
  • Unethical as they result in radiation exposure to the patient
  • Low validity in conclusion - doesn’t tell us exactly which parts of the brain are involved + how as it’s difficult to isolate different areas of brain function precisely - so it lacks important details
185
Q

What are PET Scans Performed to do?

A
  • Map normal human brain function

* Evaluate brain abnormalities - such as tumours, memory disorders, seizures + other central nervous system disorders
