34
What is critical thinking?
The process of: - examining assumptions (how do they know this?) - appraising sources (where did they get this information from?) - discerning hidden biases (what’s this person’s agenda?) - evaluating evidence - and assessing conclusions (what other explanations are there?)
35
How can you evaluate evidence in critical thinking?
By assessing whether the evidence is data-driven or anecdotal and if it justifies a cause-and-effect conclusion.
36
what does an Operational Definition
defining variables in practical, measurable terms
37
what is the point of an Operational Definition?
the purpose is when we want to replicate -- or repeat a study -- we know exactly how to go about it.
38
reliability
the study provides consistent results every time
39
what are the 4 types of reliability?
1) test-retest reliability: consistency of scores when the same test is administered on 2 occasions 2) inter-rater reliability: consistency of scores when different score raters score the same behavior 3) split-half reliability: consistency of scores when a test is split into 2 halves 4) internal consistency reliability: consistency of scores across items within a single test
40
validity
the study tests what its supposed to do
41
content validity
the extent to which a test measures the entire range of behavior/skills it's supposed to measure
42
criterion validity
check IF a test's results match well w/ other imp. measures related to what the test is supposed to measure, including concurrent + predictive validity
43
construct validity
extent to which a test measures the theoretical construct/trait it claims to measure
44
predictive validity
extent to which scores on a test predict future behavior/performance
45
a hypothesis can be tested in several ways, including?
1) descriptive methods 2) correlational methods 3) experimental methods
46
A theory
an explanation using an integrated set of principles that organizes observations and predicts behaviors or events.
47
What do hypotheses specify?
They specify what results (behaviors or events) would support the theory & what results would cast doubt on the theory.
48
descriptive methods
describe behaviors & can be the starting point of any science
49
what are some key considerations for case studies?
1) good representative sample 2) random sample 3) avoid sampling bias 4) bigger sample size 5) less variability
50
what is an advantage of random sampling?
every person in the entire group has an equal chance of participation
51
why should there be a bigger sample size used for case studies?
the bigger the sample size, the better
52
cross-sectional study
research method where data is collected from a group of ppl at a single point in time
53
longitudinal study
research method where data is collected from the same group of ppl repeatedly over a period of time
54
what are 4 kinds of cognitive bias that can influence research?
1) hindsight bias 2) overconfidence 3) illusory correlations 4) wording effects
55
hindsight bias
the tendency to believe that one has foreseen the outcome
56
illusory correlations
thinking there's a relationship when there's none
57
wording effects
the way a study is worded can greatly impact attitudes and behaviours towards it
58
What is the purpose of experimental methods in psychology?
They help investigate psychological phenomena by systematically manipulating variables to measure outcomes, with the goal of establishing cause-and-effect relationships.
59
IV (Independent Variable)
the variable that's manipulated by the researcher
60
DV (Dependent Variable)
the variable that's measured to see the effect of the IV
61
Control Group
doesn't receive the experimental treatment and used for comparison. This will test for the placebo effect.
62
Placebo Effect (also called the Pseudo Treatment)
when people experience real changes in their health or behavior simply because they believe they're receiving treatment, even if it has no active ingredients -- power of belief making them feel better and sometimes people 'feel' better because they think they should
63
Experimental Group
the group that receives the treatment or manipulation
64
Cofounding Variables
uncontrolled variables that could influence the results of an experiment if not controlled
65
Random Assignment
assigning participants to experimental and control groups by chance to minimize pre-existing differences. This controls for the Cofounding Variable.
66
what are the 2 types of experimental designs?
1) between subjects: diff. groups of participants are exposed to diff. levels of the IV 2) within-subjects: some group of participants are exposed to all levels of the IV
67
what does correlation indicate & what doesn't it imply?
it indicates the strength of a relationship between variables it doesn't imply cause-and-effect relationship
68
3 kinds of correlation
positive correlation: as one variable increases, the other variable also increases negative correlation: as one variable increases, the other variable decreases zero correlation: no relationships exists: changes in 1 don't predict changes in the other
69
mean & calculation
the avg. of a set of numbers calculation: sum of all scores and no. of scores
70
median
the middle value in a set of numbers
71
central tendency
the center of a data set -- mean, median and mode
72
mode
the most frequently occurring value in a set of numbers
73
range
the difference between the highest and lowest values in a set
74
percentile rank
the percentage of scores in a distribution that a particular score is above
75
inferential statistics
methods used to make inferences about the population based on sample data
76
t-tests & an example of it
used to determine if there's a significant difference between the means of 2 groups ex: compare the avg. scores of 2 diff. groups on a test or measure
77
chi-square tests
used to determine if there's a significant association between 2 categorical variables - ex: color preference changes depending on another thing like age group
78
what is ANOVA (Analysis of Variance) used to determine?
if there are significant differences between the means of 3 or more groups
79
p-value
the probability of obtaining the observed results, or more extreme results, if the null hypothesis is true
80
null hypothesis
refers to the assumption that there's no effect / difference in the situation being studied
81
statistical significance
indicates the likelihood that the result will happen by chance
82
what p-value indicates statistical significance?
a p-value of the less than 0.05
83
on a positively skewed graph, what is the highest out of range, mode, and median?
mode
84
on a negatively skewed graph, what is the lowest out of range, mode, and median?
mean
85
what kind of tests are the TAT (Thematic Approach Test) and the Rorschach inkblot test?
Projective Tests
86
How should participants be protected in psychological research?
Participants must be protected from physical and emotional harm and should feel safe. They can leave if uncomfortable.
87
Why do people prefer a therapist whose values align with their own?
People feel more comfortable with therapists who share similar values, as it builds trust and avoids discomfort that can arise from differing beliefs.
88
Internal Validity
extent to which changes to the DV can be attributed to the manipulation of the IV
89
List an example of Internal Validity
ensuring that a drug & not other factors, causes improvement in patient symptoms
90
External Validity
the generalizability of the findings to other populations, settings or conditions
