Q

What are philosophers interested in, when it comes to psychology?

A

They are interested in the mind, asking questions like “are the mind and body one” or “are we born with knowledge or do we acquire it as we grow up?”

Q

What is dualism?

A

The theory that the mind and body are two separate entities, and that the mind/soul is immaterial (meaning it cannot be measured or observed). The body is material, including memory, and perception, which can be measured.

Q

What is philosophical realism?

A

Realists believe that perceptions of the physical world are produced entirely by information from the sensory organs. When you look at something, the brain is using ONLY that information to produce your perception of the book in front of you. Essentially, the brain is like a camera.

Q

What is philosophical idealism?

A

Idealists believe that perceptions of the physical world are made from the brains interpretation from sensory organs. According to idealists, light is bouncing off the page, hitting your eye, and your brain is using that information, PLUS all the information it has about the world to produce perception. Essentially, the brain is painting a picture of what it believes is out there.

Q

What is radical behaviourism and who founded it?

A

Radical behaviourism was founded by B.F. Skinner. Skinner believed that internal events do exist, but there is no need to study them. He thought you could predict behaviour externally, completely dismissing internal events.

  1. He believed in the principal of reinforcement: we repeat behaviours that lead to positive outcomes, and do not repeat behaviours that lead to negative or neutral outcomes.
  2. He also thought that free will was an illusion, since internal thoughts do not influence us.

Q

What is empirical evidence?

A

Empirical evidence can be defined as information received by the means of the senses, particularly by observation, and documentation of patterns and behaviour through experimentation.

54
Q

What is a theory?

A

Theories can be denoted as hypothetical explanations of natural phenomena.

55
Q

What is a hypothesis?

A

A hypothesis is a specific falsifiable prediction made by a theory. Also can be denoted as a tentative statement about the relationship between two or more variables.

56
Q

What is falsifiability?

A

Falsifiability is not about whether certain ideas are false, rather it is about whether data can reveal if they are false.

57
Q

Can a hypothesis be proven right?

A

Observations that are consistent with a hypothesis can increase our confidence that the hypothesis is correct, but they can never make us absolutely sure if it is right.

58
Q

What are the steps within the scientific method?

A
  1. Develop a theory
  2. Derive a falsifiable hypothesis
  3. Gather empirical evidence
  4. Evaluate your research
59
Q

Why is empirical research hard sometimes?

A

Empirical research is difficult because humans are highly complex, variable and reactive. No one person has the same feelings, thoughts and beliefs.

60
Q

What does complexity, variability, and reactivity refer to?

A

variability - people react differently in the same situations (eg. you scream in a horror movie, I cry)

complexity - people are complex and there are not always easy answers to questions (eg. there are a lot of different potential reasons behind depression)

reactivity - people react differently when they know they are being observed (eg. if you litter normally, you probably won’t litter if you’re being watched)

61
Q

What does measurement refer to?

A

How we define what we wish to measure, and then how we choose to detect it.

62
Q

What is an operational definition?

A

An operational definition is a description of how a concept will be measured. Turning a concept into a quantity. Ex: Happiness can be measured by facial expression, how many times they smile in an hour, brain activity, or even a survey.

63
Q

What do we use for “detection?”

A

Now that we have defined what we want to measure, we need a way to detect it. A detector is an instrument, device, or rater which can detect the property that we have defined.

64
Q

What determines a good operational definition?

A

Construct validity defines how well a test or experiment measures up to its claims. It refers to whether the operational definition of a variable actually reflect the true theoretical meaning of a concept.

65
Q

What is internal validity?

A

Internal validity is the extent to which you can be confident that a cause-and-effect relationship established in a study cannot be explained by other factors.

66
Q

What is external validity?

A

External validity is the validity of applying the conclusions of a scientific study outside the context of that study. In other words, it is the extent to which the results of a study can be generalized.

67
Q

What makes a good detector?

A

Power and reliability.

68
Q

What does power refer to?

A

Statistical power is the likelihood that a test will be able to to detect an effect (during a research study) when one truly exists.

69
Q

What does reliability refer to?

A

In statistical terms, reliability refers to the reproducibility and consistency of a measure.

70
Q

Reliability vs. validity?

A

Reliability refers to the consistency of the measurements, whereas validity refers to the accuracy.

71
Q

Types of ways to measure reliability?

A 
Inter-rater reliability score, test-retest (take the test multiple times), and internal consistency. 
Internal consistency (i.e. split test reliability, split 50% of items and compare with the other 50% to see if there is consistency)
72
Q

What can we use test re-test on?

A

We can use retest reliability on something that is consistent over time like IQ, but not happiness because that fluctuates

73
Q

If something is reliable, it does not guarantee_____?

A

validity.

74
Q

What are demand characteristics?

A

Demand characteristics are those aspects of an observational setting that cause people to behave as they think someone else wants or expects. For example, if a researcher asked, “Do you think it is wrong to cheat on exams?” the participant would feel obligated to say yes because that is the answer they think the researcher is expecting back.

75
Q

How do we avoid demand characteristics?

A

Naturalistic observation, privacy and control, and unawareness.

76
Q

What does naturalistic observation refer to?

A

Naturalistic Observation: a technique used to gather scientific information by unobtrusively observing people in their natural environments.

Unfortunately naturalistic observation is not always practical. First, some events do not just occur naturally. Secondly, some events can only be observed through direct interaction such as by conducting an interview or hooking someone up to a heart rate monitor.

77
Q

What does privacy and control refer to?

A

People are less likely to be influenced by demand characteristics when they can’t be identified as the authors of their actions. Psychologists often take advantage of this by allowing participants to respond privately (i.e., through a questionnaire) or anonymously (not collecting personal information).

78
Q

What does unawareness refer to?

A

Make people unaware of the true purpose of the observation, then they do not feel obliged to act a certain way. This is why psychologists will mislead people by telling them they are studying one thing, when they are really studying another, or by giving people pointless tasks/asking pointless questions simply so that people can’t easily guess the study’s true purpose.

79
Q

What is observer bias?

A

The tendency for observers’ expectations to influence both what they believe they observed, and what they actually observed.

80
Q

How do we avoid observer bias?

A

Using a double-blind experiment.

81
Q

Sample (n) vs. population (N)

A

A partial collection of people or animals or things drawn from a population.

82
Q

How do we graphically represent data?

A

Frequency distribution: graphic representation showing the number of times in which the measurement of a property takes on each of its possible values.

Normal distribution(bell curve): mathematically defined distribution in which the frequency of measurements is highest in the middle and decreases symmetrically in both directions.

83
Q

What are descriptive stats?

A

Brief summary statements that capture the essential information.

84
Q

What are the two common kinds of descriptive stats?

A

Central tendency and the variability.

85
Q

What does the central tendency tell us?

A

The mode (the value of the most frequently observed measurement), the mean (the average value of all the measurements) and the median (the value that is in the middle, 50th percentile).

86
Q

Why do we usually use all three values?

A

If we have a skewed graph, the measure of central tendency changes.

87
Q

What does variability measure?

A

Variability tells us how much the measurements differ from each other, or roughly how wide the distribution is.
Variability can be measured by the range and standard deviation.

88
Q

What does the range refer to?

A

Range: largest value minus the smallest

89
Q

What does the SD refer to?

A

Standard deviation: how each of the measurements in a frequency distribution differ from the mean. Essentially, how far, on average the various measurements are from the centre of the distribution.

90
Q

Central tendency and variability are ______ of each other.

A

Independent.

91
Q

Correlation vs. Causation

A

Correlation - whether two properties are related

Causation - whether one of these properties causes the other

92
Q

What is the correlation coefficient?

A

Is a mathematical measure of both direction and strength of a correlation.

93
Q

What are the values of “r” and their meaning?

A

If r=1, the variables have a perfect, positive correlation
If r=-1, the variables has a perfect, negative correlation
r=0, the variables have no correlation
r>0<1, means there is a correlation but it is not perfect

94
Q

What is the third-variable problem?

A

Refers to the fact that the natural correlation between two variables cannot be taken as evidence of a casual relationship between them because a third variable may causing them both.

95
Q

How do we minimize this issue?

A

Random assignment, or experimentation.

96
Q

What is random assignment?

A

A procedure that assigns participants to a condition by chance. This makes sure that the variable we are looking to investigate is the only one that was manipulated.

97
Q

How do we know if random assignment has failed?

A

If p>0.05.

98
Q

What is a case method?

A

Studying a single individual or small group of people in extreme depth.

99
Q

What does random sampling refer to?

A

Allowing equal chance of all the population to be included in the sample. This random sample allows us to say it is representative of the entire population, and can be generalized.

100
Q

What does replication refer to?

A

A replication is an experiment that uses the same procedures as a previous experiment but with a new sample from the same population

101
Q

Nuremberg Code and the Declaration of Helsinki…….

A

spelled out rules for the ethical treatment of people who participate in experiments.

102
Q

Any studies involving humans or tissue must go through the______?

A

TCPS (tri-council policy statement).

103
Q

What agencies are in the TCPS?

A

the Canadian Institutes of Health Research (CIHR), the National Sciences and Engineering Research Council (NSERC), and the Social Sciences and Humanities Research Council (SSHRC).

104
Q

What are the three main pillars of the TCPS?

A
  1. Respect for persons
  2. Concern for welfare
  3. Justice
105
Q

What does respect for persons refer to?

A

Researchers should show respect for persons, and their right to make informed decisions for and about themselves without influence.

106
Q

What does concern for welfare refer to?

A

This means that it should attempt to maximize benefits and reduce risks to the participant. Potential welfare risks include physical harm (sleep deprivation, administration of alcohol or drugs, unlabeled food products, un-sanitized equipment), stress/distress, or losing privacy and confidentiality.
Concern for welfare in groups - stigmatization and discrimination. This is secondary to welfare for individuals.

107
Q

What does justice refer to?

A

Third, research should be just, which means that it should distribute benefits and risks equally to all participants without prejudice. In addition there also needs to be fair and equitable treatment. No imbalance of power.

108
Q

What does consent refer to?

A

Consent is “informed” when you are able to fully understand the consequences of being in a study and make a decision about your participation

109
Q

What does assent refer to?

A

Assent is the agreement of someone not able to give legal consent to participate in the activity, like potentially someone who is an elder with dementia etc.

110
Q

Studies can only be performed after they have been reviewed by _______?

A

Research and ethics board.

111
Q

Who is on a research and ethics board?

A

Usually composed of experienced researchers, university staff, and laypeople from the community like business leaders or members of the clergy.

112
Q

What are the important rules for conduct of psychological research?
CCCDDHRB

A

Informed consent: participants need to provide a verbal agreement, and they are aware of all the potential or harmful risks. Participants are free to withdraw from the study at any time.

Freedom of coercion: Psychologists cannot coerce participation. Coercion does not only mean physical or psychological coercion, but also monetary coercion.

Protection from harm: Pick the safest method

Risk-benefit analysis: Participants cannot be subjected to large risks only small risks that they would ordinarily face in everyday life. The psychologist must demonstrate that the small risks are outweighed by the social benefits of knowledge gained from the study.

Deception: Researchers cannot deceive participants about any aspect of a study that could cause them physical or psychological harm. Deception may only be used when it is justified by the study’s scientific, educational or applied value.

Debriefing: if a participant was deceived in any way, the psychologist must provide a debriefing, which is a verbal description of the true nature and purpose of the study.

Confidentiality: keep private and personal information obtained confidential

113
Q

Who is responsible for animal ethics?

A

CCAC - The Canadian Council for Animal Care

114
Q

What 3 R’s must be followed for animal research?

A

Replacement (researchers have to prove there is no alternative to using animals for research)

Reduction (use the least amount of animals possible to achieve research)

Refinement (procedures must be modified to minimize discomfort, infection, illness, and pain and maintain animal welfare)

115
Q

What is an experimental group?

A

Receives the treatment.

116
Q

What is a control group?

A

Does not receive treatment.

117
Q

What is non-experimental research?

A

Research that does not involve manipulating any variables.

In this type of research, we describe behaviour, look for relationships and make predictions.

118
Q

Why do we use non-experimental research?

A

Used when we cannot use experimental techniques. This could be because it is not possible to experiment or its unethical.

119
Q

What can non-experimental research not do?

A

Cannot determine cause and effect

120
Q

Examples of non experimental research include____?

A

Naturalistic observation, case studies, and surveys.

121
Q

What is placebo?

A

When you experience something based on expectation, but not by the actual experience.

122
Q

What are some issues with self-reporting?

A
  1. Demand characteristics
  2. Misunderstood questions (vague, two possible answers etc.)
  3. Response set (we watch for patterns like, clicking A,A,A,A)
123
Q

What are heuristics?

A

Mental shortcuts that help us simplify reality. For example, if you need to go to the grocery store, you do not analyze every way to get there, you automatically go the simplest way.

124
Q

What is a representativeness heuristic?

A

“Like goes with like.” Judging the probability of an event by how similar is to some prototype. Ex: a photo of a man ready for work, and a man in a robe yawning. Which guy will be late? Our brain automatically assumes it would be the one in the robe.

Q

What is an availability heuristic?

A

“Off the top of my head.” We estimate the likelihood of something based on how quickly it comes to mind. Ex: Driving or planes, which is more unsafe? People assume flying because of plane crashes, when in reality it is actually cars.

Q

How can a graph be skewed?

A

Right skewed (positively skewed), left skewed (negatively skewed) change the mean (maybe median?)

131
Q

How can lying occur with statistics?

A
  1. Use of misleading axes
  2. Using the wrong measure of central tendency (i.e. like the mean, and the mean is sensitive to outliers so it does not give an accurate representation)
  3. Sampling bias: we need to be critical of how the sample was calculated
  4. Misleading comparisons
  5. Confusing correlation with causation
