66
what are basic ideas/principles of the code of ethics regarding human experimentation?
- must not create pain/discomfort/stress/anxiety
- participant must give consent voluntarily
- must inform participants enough to give consent
- must debrief & give results to participant after study
- must keep participant info confidential
- participant may back out at anytime
- research must be culturally sensitive
67
What are the major drawbacks of hindsight bias understanding?
causes/spreads misinformation, leads to overconfidence, overestimate intuition
68
What approach to understanding do scientists prefer & why?
scientific method/scientific attitude (?)
69
describe the characteristics of a good theory
- effectively organizes range of self-reports & observations
- leads to a clear hypothesis that anyone can use to check theory
- often stimulates research that leads to a revised theory
70
Why are operational definitions important?
allow for replication of experiment
71
What is a reliable measurement?
data is consistent
72
list the five ethical principles in the American Psychological Association (APA) code of ethics
beneficence & nonmaleficence, fidelity & responsibility, integrity, justice, respect
73
list the primary ethical principles for conducting research with humans
- obtain informed consent
- protect participants from physical/emotional harm/discomfort
- keep participant's info confidential
- fully debrief after research
74
what are the justifications & criticisms for research using animals
justification: leads to development of human technology, learn about humans
criticism: animal rights & welfare
75
What is a case study? identify advantages & drawbacks
studying one person to observe phenomena; case studies only need 1 person and gen done when it is unethical to perform experiment on others but can be misleading bc it only uses one person
76
How can the findings of case studies mislead us in everyday life?
uncontrolled variables, data can be incorrect if individual is atypical, lead to mistaken judgments/false conclusions
77
what is the greatest advantage of naturalistic observation
can be done when not ethical to manipulate variables
78
what biases can occur when conducting naturalistic observation
experimenter expectancy effect
79
what are some advantages & disadvantages of survey research?
advantages: quick & inexpensive
disadvantage: word choice & sampling bias
80
Why do researchers rely on random sampling
to rule out lurking variables
81
What is the main goal of correlational research and how is it achieved
goal: see how two values relate to other
achieved: create scatter plot
82
Why are we unable to draw casual conclusions from correlational findings
correlation does not equal causation, correlational relationships do not prove that it is the cause/directly related to something
83
how can correlational research predict behavior
show likelihood/possibility of something happening based on the value of another factor
84
Describe the logic of experimentation
- start w/equivalent groups of participants
- treat equally in all respects except for independent variable which is isolated & manipulated
- measure how groups respond
85
how does random assignment differ from random sampling
- random assignment = dividing participants by chance into experimental & control groups
- random sampling = sample that represents population for survey
86
describe Rosenzweig's experiment
male rats were separated into enriched & deprived environments for period of time before they were euthanized & their brain was measured for thickness, heaviness, synapses, and acetylcholine receptors
87
why do researches manipulate two independent variables in the same experiment?
allows study of possible relationship of independent variables to each other
88
why does experimenter expectancy effects lower the internal validity of experiments
causes bias in the way experimenter may treat participants
89
How do researchers minimize experimenter expectancy effects?
double blind procedure
90
as a critical thinker, what questions should you ask when someone makes a claim or assertion?
- How do they know?
- What is their agenda/
- is the conclusion based on anecdote/intuition or evidence?
- Does the evidence justify cause-effect conclusion?
- Alternative explanations?
91
Contrasts descriptive & inferential statistics
- descriptive = data to measure & describe
- inferential = how variables relate to each other
92
in a normal curve, what % of cases should fall within 1 standard deviation on either side of mean
68%
93
what are the benefits of correlational research
works w/large groups, can be done where experiment isn't ethical/possible
94
what are the benefits of experimental research
specifies cause & effect, variables controlled
95
what are the cons of experimental research
sometimes not feasible, results may not generalize to other contexts, sometimes unethical to manipulate
