Q

Falsifiability

A

the principle that a proposition or theory could only be considered scientific if in principle it was possible to establish it as false. (ex. Freuds theory of the unconscious mind lacks falsifiability

17
Q

Convenience Sample (Qualitative Measures-Sample)

A

when a researcher picks participants based on ease of accessibility to finding them (ex. surveying only people that live in your neighborhood)

18
Q

Survey (Qualitative Measures)

A

obtaining self reported attitudes and behaviors by asking questions

19
Q

Social Desirability Bias (Qualitative Measures-Survey)

A

people lie to look good when asked things about themselves or their beliefs

20
Q

Self Report Bias (Qualitative Measures-Survey)

A

people may misreport their own behavior, thoughts or feelings perhaps because they don’t know or don’t remember the accurate answer

21
Q

Framing (Qualitative Measures-Survey)

A

how you frame the question can impact others answers (ex. are you in favor of socialized medicine or free healthcare for all?)

22
Q

Naturalistic Observation (Qualitative Measures)

A

research conducted in the natural setting of animals or humans; no interaction is done with the subjects

23
Q

Case Study (Qualitative Measures)

A

study one person/group in depth in hopes to reveal things true of us all. (ex. Phineas Gage.) Disadvantage is that you may be able to generalize to larger population

24
Q

Correlational Study (Qualitative Measures)

A

measures the relationship between two variables WITHOUT manipulating a variable

25
Q

Correlation (Correlational Study)

A

measures the relationship between two variables (CORRELATING DOES NOT SHOW CAUSATION)

26
Q

Positive Correlation (Correlational Study)

A

both variables increase or decrease together

27
Q

Negative Correlation (Correlational Study)

A

as one variable increases the other decreases

28
Q

Illusionary Correlations (Correlational Study)

A

the perception of a relationship between variables where none exist

29
Q

3rd Variable Problem (Correlational Study)

A

a 3rd factor that can be the real relationship (ex. heat and shark attacks)

30
Q

Directionality Problem (Correlational Study)

A

it can be difficult to know which variable is the cause and which is the effect in a correlational study (ex. stress and mental health)

31
Q

Experiment

A

a research method in which an investigator manipulates one or more factors (IV) to observe/measure the effect on some behavior or mental process (DV). Seeks to identify cause and effect relationships. Disadvantage is that it can be hard to generalize tot he real world.

32
Q

Experimental Condition/Group (Experiment)

A

exposes a participant to treatment

33
Q

Control Condition/Group (Experiment)

A

contrast to the experimental conditions; acts as a comparison because participant does not receive treatment OR receive a placebo

34
Q

Random Assignment (Experiment)

A

(ONLY USED IN EXPERIMENTAL METHOD) the process in which subjects are placed into a experimental or control group without bias

35
Q

Placebo Effect (Experiment)

A

results caused by expectations alone; you think that you will experience an effect, therefore you perceive that there is an effect

36
Q

Single Blind (Experiment)

A

only researchers (not participants) know who is in the placebo and treatment group

37
Q

Double Blind (Experiment)

A

participants and research staff are ignorant about the treatment/placebo group given to each subject, used so researchers’ expectations can’t influence the result

38
Q

Peer Review

A

evaluating the quality of research by one’s peers int he scientific community

39
Q

Replication

A

repeating an experiment or study to see if a similar result happens again

40
Q

Meta-Analysis

A

systematic review of multiple, already published/completed studies
