Q

Critical Thinking

A
  • making reasoned judgements (people’s judgements should be logical and well thought out)
  • the ability to ask and seek answers for critical questions at the right time
  • can help avoid false beliefs that may lead to poor decisions or prove dangerous to our mental and physical health

Q

4 Basic Criteria for Critical Thinking

A

1) there are very few “truths” that do not need to be subjected to testing (only religious/personal beliefs/values can be accepted without proof)
2) all evidence is not equal in quality
3) just because someone is considered to be an authority or to have a lot of expertise does not make everything that person claims automatically true
4) critical thinking requires an open mind (balance of skepticism and willingness to consider possibilities)

Q

Correlation Coefficient

A
  • represents the direction of the relationship and its strength
  • represented by “r”
  • if positive –> the 2 variables increase in the same direction
  • if negative –> inverse relationship
  • number always ranges between +1.00 and -1.00
  • number closer to +1.00 is strong positive correlation
  • number closer to -1.00 is strong negative correlation
  • if number is closer to zero it is weaker

Q

Placebo

A

harmless substitute which has no medical effect

33
Q

Experimenter Effect

A

when researcher is measuring dependent variable, they could unintentionally give participants clues about how they’re supposed to respond

34
Q

Single-Blind Study

A

participants are “blind” to treatment they receive

35
Q

Double-Blind Study

A

participants and experimenters are “blind” to treatment participants receive

A

set of characteristics that people believe is shared by all members of a particular social category

Q

A

research for knowledge

38
Q

Q

Ethnocentrism

A

being biases based on your own ethnicity

40
Q

Ethical Treatment

A

people who volunteer for a study will be able to expect that no physical or psychological harm should come to them

41
Q

Institutional Review Boards (IRBS)

A
  • groups of psychologists or other professionals who look ever each proposed study and judge it according to its safety and consideration for research participants
  • usually at universities because that is where most psychological research is done
  • they look at all aspects of projected study (written material that explains the research, potential subjects, equipment used in study)
42
Q

Common Ethical Guidelines

A

1) rights and well-being of participants must be weighed against study’s value to science
2) participants must be allows to make an informed decision about participation
3) deception must be justified
4) participants may withdraw from study at any time
5) participants must be protected from risks or told explicitly of risks
6) investigators must debrief participants
7) data must remain confidential
8) if for any reason study results in undesirable consequences for participant, researcher is responsible for detecting and removing, or correcting, these consequences

43
Q

Informed Consent

A

researchers using participants under 18 have to have their parents informed and have them give consent

44
Q

Debriefing

A

participants have to be told after study the true nature of the study, expectation of results, and if deception was used why it was necessary

45
Q

Animal Research Pros

A
  • animals have shorter life-span –> looking at long-term effect is easier
  • animals are easier to control (diet, living arrangement, genetic relatedness)
  • animals engage in simpler behavior –> easier to see effects of manipulations
  • animals can be used in ways that researchers can’t use people (researchers avoid exposing animals to unnecessary pain and suffering)
46
Q

White Laboratory Rats

A

recognized species different from ordinary rats because it was bred with its own kind so that each white rat is a genetic “twin” of all the others

47
Q

Experiment

A

only way to determine cause of behavior by manipulating variable
PROS: can find causal relationship, researcher controls everything
CONS: might be artificial behavior

48
Q

Statistics

A

branch of math that’s concerned with the collection and interpretation of data from samples

49
Q

Descriptive Statistics

A

way of organizing numbers and summarizing them so that they can be understood

50
Q

Measures of Central Tendency

A

number that best represents central part of frequency distribution

51
Q

Measures of Variability

A

used to indicate how spread out data are (tightly packed or widely dispersed)

52
Q

Frequency Distribution

A

table or graph that shows how often different numbers, or scores, appear in a particular set of scores

53
Q

Histogram

A

bar graph

54
Q

Polygon

A

line graph; allows researchers to see shape of a set of data easily

55
Q

Central Tendency

A

data points in area with highest frequency

56
Q

Variability

A

data points in area with lower frequency

57
Q

Normal Curve/Bell Curve

A

used as a model for standard deviation

58
Q

Skewed

A

distribution is not even; scores are concentrated toward one side of the distribution

59
Q

Negatively Skewed

A

tail to the left

60
Q

Positively Skewed

A

tail to the right

61
Q

Bimodal Distribution

A

frequency polygon shows 2 high points rather than 1; mean, median, and mode are useless

62
Q

3 Measures of Central Tendency

A
  • mean
  • median
  • mode
63
Q

Mean

A

average

64
Q

Median

A

score that falls in the middle of an ordered distribution of scores

65
Q

Mode

A

most frequent score is taken as central measure

66
Q

Outliers

A

values that are extreme; distort accuracy

67
Q

When Distribution is Skewed

A
  • mean is pulled to direction of tail of direction
  • mode is highest point
  • median is between mean and mode
68
Q

2 Measures of Variability

A

range and standard deviation

69
Q

Range

A

difference between highest and lowest scores in the set of scores

70
Q

Standard Deviation

A

can’t be negative; how similar your data is together (clumped or spread out); the smaller the better (mean is useful indication of data)

71
Q

Z Score

A

how many standard deviations you are away from the mean

72
Q

Inferential Statistics

A

allow researchers to draw conclusions/inferences about results of research and about whether those are only true for specific group in study or if results can be generalized to larger population

73
Q

Statistic Significance

A

way to test differences to see how likely differences are to be real

74
Q

Significant Difference

A

not due to chance because it’s too important

75
Q

T-Test

A

testing if results are statistically significant

76
Q

p is less than or equal to 0.05

A

the data is significant and you can draw conclusions that your independent variable caused your dependent variable

77
Q

F-Test / Analysis of Variance

determines if 3+ means are different from each other; can also evaluate more than 1 independent variable at a time

78
Q

Chi-Square
