Q

What are the steps to the scientific method

A
  • scientific theories generate hypotheses, which are specific and testable predictions
  • if the hypothesis is confirmed: a new hypothesis stems from it, and the original theory receives added support
  • if hypothesis is rejected: the original hypothesis may be modified and retested, or it may be modified or rejected

63
Q

Social desirability

A

64
Q

Validity

A

The degree to which an instrument or procedure actually measures what it claims to measure

65
Q

Variable

A

The object, concept, or event being measured

66
Q

What are the five characteristics of quality research?

A
  1. measurements are objective, valid, and reliable
  2. the research can be generalized
  3. it uses techniques that reduce bias
  4. the findings are made public
  5. Results can be replicated
67
Q

How can bias might influence the outcome of the study?

A
  • demand characteristics affect how participants respond in research studies (they attempt to portray themselves in a positive light,
  • researchers can influence the outcomes of their own studies, even unintentionally
68
Q

Between subject design

A

An experimental design in which we compare the performance of participants who are in different groups

69
Q

Case study

A

An in depth report about the details of a specific case

70
Q

Confounding Variable

A

A variable outside the researcher’s control that might affect or provide an alternative explanation for the results

71
Q

Control group

A

The group that does not receive the treatment or stimuli targeting a specific behaviour; this group therefore serves as a baseline to which the experimental group is compared

72
Q

Correlational research

A

Involves measuring the degree of association between two or more variables

73
Q

Dependent variable

A

The observation or measurement that is recorded during the experiment and subsequently compared across all groups

74
Q

Experimental group

A

The group in the experiment that receives the treatment or the stimuli targeting a specific behavior

75
Q

Illusory correlations

A

Relationships that really exist in the mind, rather than in reality

76
Q

Naturalistic observation

A

Observations that unobtrusively observe and record behaviour as it occurs in the subject’s natural environment

77
Q

Qualitative research

A

Examining an issue or behavior without performing numerical measurements of the variables

78
Q

Quantitative research

A

Examining an issue or behavior by using numerical measurements and/or statistics

79
Q

Quasi-experimental research

A

A research technique in which the two or more groups that are compared are selected based in predetermined characteristics

80
Q

Random assignment

A

A sampling technique in which every individual of a population has an equal chance of being included

81
Q

Research Design

A

A set of methods that allows a hypothesis to be tested

82
Q

Self-reporting

A

A method in which responses are provided directly by the people who are being studied, typically through face to face interviews, phone surveys, paper and pencil tests and web based questionnaires

83
Q

Third variable problem

A

The possibility that a third, unmeasured variable is actually responsible for a well established correlation between two variables

84
Q

Within-subject design

A

An experimental design in which the same participants respond to all types of stimuli or experience all experimental conditions

85
Q

What does it mean when variables are positively or negatively correlated?

A
  • when two or more variables are positively correlated, they increase or decrease
    ex) income and education level are positively correlated
  • negatively correlated, if one increases the other decreases
    ex) substance abuse may be inversely related to cognitive performance- higher levels of substance abuse are often associated with lower cognitive function
86
Q

How do experiments help demonstrate cause and effect relationships

A
  • experiments rely on randomization and the manipulation of an independent variable to show cause and effect
  • at the beginning of an experiment, two or more groups are randomly assigned-a process that helps ensure that the two groups are about equivalent
  • researchers manipulate an independent variable. At the end of the study, if one group turns out to be different, that difference is most likely due to the effects of the independent variable
87
Q

What are the pros and cons of descriptive research designs?

A
  • naturally occurring behaviour and providing detailed observations of individuals
88
Q

What are the pros and cons of the correlational research design

A
  • when they are used in descriptive research, we can see how key variables are related
89
Q

What are the pros and cons of experimental research design?

A
  • they can be used to test for cause and effect relationships..
  • the laboratory experiments might not generalize to real world situations
90
Q

Debriefing

A

When researchers explain the true nature of the study, especially the nature of and reason for any deception

91
Q

Deception

A

misleading or only partially informing participants of the true topic or hypothesis under investigation

92
Q

Informed consent

A

A potential volunteer must be informed and give consent without pressure

93
Q

Research ethics board (REB)

A

A committee of researchers and officials at an institution charged with the protection of research participants

94
Q

Why are animals often used in scientific research

A
  • many research questions that affect medical and public health cannot be answered without animal testing
  • obvious ethical considerations may not allow such research to be conducted on human subjects
  • by working with animal models, scientists can control genetic and environmental variables that cannot be controlled with humans
95
Q

What is the role of using deception in psychological

A
  • often the case that fully disclosing the purpose of a study before people participate in it would render the results useless
  • specific details of the study are not provided during informed consent
  • when deception is used, researchers must justify that the benefits of doing so outweigh the costs
96
Q

Central tendency

A

A measure of the central point of a distribution

97
Q

Descriptive Statistics

A

A set of techniques used to organize, summarize and interpret data

98
Q

The number of observations that fall within a certain category or range of scores

99
Q

100
Q

Mean

A

The arithmetic average of a set of numbers

101
Q

Median

A

The point on the horizontal axis at which 50% of all observations are lower and 50% of all observations are higher

Q

Mode

A

The category with the highest frequency (that is, the category with the most observations)

103
Q

107
Q

Standard deviation

A

A measure of variability around the mean

108
Q

Statistical significance

A

The means of the group are farther apart than you would expect them to be by random chance alone

109
Q

Variability

A

The degree to which scores are dispersed in a distribution

110
Q

How and why do psychologists use significance tests?

A
  • help tell us whether differences between groups or distributions are meaningful
  • how much variability there is among individuals within each of the groups will determine whether the averages are the significantly different
  • to test whether groups really are different
