25
Laboratory observation
Watching behavior without interfering in a lab setting
26
Case study
In depth study of an individual or group (usually rare)
27
Meta-analysis
Reviews results of other studies to gain a more accurate understanding
28
Survey
Non experimental research methods; asks people questions about their behavior/attitude
29
Social desirability effect
Tendency to put a more favorable answer than the truth
30
Framing (“wording effects”)
Way a question strongly influences an answer
31
Scatterplot
Identifies possible relationships between changes observed in 2 different sets of variables
32
Line of regression
Line of best fit-shows the direction in a group of points
33
Correlation coefficient
a # represented by “r” that ranges from -1.0 to +1.0
34
r
Correlation coefficient
35
Positive correlation
Two variables will increase or decrease together
36
Negative correlation
As one variable increases the other will decrease
37
Hypothesis
A testable prediction usually using “if, then” statement
38
Experimental design
Describes the way things/info is distributed
39
Independent variable
Variable that the scientist controls/changes
40
Dependent variable
Variable being tested/measured due to exposure of the IV
41
Operational definition
Describes precise procedures and measures
42
Cofounding variable (“third variable problem”)
Extra factor that interferes with the dependent variable
43
Directionality problem
When its already known that the two variables are related, but not which one is the cause versus which one is the effect
44
Validity
Did the test measure what it needed/aimed to measure
45
Experimental group
Group exposed to the IV
46
Control group
Group that gets no treatment or a placebo
47
Sample
A small portion of something that represents a whole
48
Representative sample
The sample that most accurately represents the whole group/population
49
Population
All the cases in a group being studied that can be sampled
50
Random selection
Form of sampling that ensures everything has an equal chance of being picked – – limits bias
51
Random assignment
Each participant has an equal chance of being placed into any group (limits effects of cofounding variables)
52
Sampling bias
Sample selected that doesn’t represent the population being studied
53
Quasi-experimental design
Differences between experimental and control group is predetermined because of variable being studied already exist
54
Qualitative measures
Non-numerical data
55
Quantitative measures
Numerical data
56
Placebo effect
When a person believes they’re experiencing changes, even though they’re only taking a placebo
57
Single-blind study
Do not let participant know if they are in the experiment or control group
58
Experimenter bias
Expectations of the researcher, may influence perception of results by giving clues on how to respond
59
Double-blind study
Participant and researchers don’t know who has received the IV
60
Likert scale
How strongly you feel about something
61
Histogram
A bar graph depicting a frequency distribution
62
Descriptive statistics
They describe data: Measure Of Central Tendency (MOCT) and Measure of Variation (MOV)
63
Normal curve
Bell-shaped curve that describes the distribution of many types of data
64
Measure of Central Tendency
A single score that represents a whole set of scores
65
Mode
They most frequently occurring score(s) in a distribution
66
Mean
The average of a distribution, obtained by adding the scores and then dividing by the number of scores
67
Median
The middle score in a distribution
68
Positively skewed distribution
When a few outliers are much higher than the mean
69
Negatively skewed distribution
When a few outliers are much lower than the mean
70
Multimodal distribution (bimodal distribution)
Multiple modes; two or more scores appear most frequently
71
Measures of variability
Shows you how similar or diverse your score are: range, standard deviation
72
Range
Subtract the lowest score from the highest score to see how far apart they are
73
Standard deviation
Calculates how far apart scores are and determines how far each individual score varies from the mean
74
Z-score
Indicates how far away that score is from the mean
75
Inferential statistics
Used to determine if thee results from the sample can be applied to the population
76
p value
A number describing how likely it is that results were due to chance
77
Statistical significance
Proof beyond reasonable doubt that the results were NOT due to chance, but rather due to the IV
78
American Psychology Association (APA)
Organization that represents psychologist in the United States
79
Institutional Review Board
Federally-mandated, locally-administered groups charged with evaluating risks and benefits of human participant research at their institution
80
Informed consent
The participant is given enough info on the study to make a decision on his/her participation
81
Debriefing
When an experimenter tells the subject more info about the studies purpose and procedures after the study is completed
82
Research confederates
Individuals who seem to be participants but in reality are part of the research team
83
Institutional Animal Care and Use Committee (IACUC)
Federally mandated committee – – that oversee its institutions animal care and use program, facilities, and procedures
84
Wilhelm Wundt
Father of psychology -started first psych lab
85
Sigmund Freud
Founded dynamic/psychoanalytic perspective. Believed behavior is driven by our “unconscious“ mind
86
John B. Watson
Founded behavioral perspective. Wanted psychology to be a real scientific discipline. We’re conditioned to make associations
87
Carl Rogers
Founded humanistic perspective. Unconscious mind/rewards and punishments argued we have free will
88
Charles Darwin
Adopted evolutionarily perspective. Says human behavior is due to our adaptations from ancestors that has led to success— in the past
