Q

Idiographic assessment

A

Data collection that evaluates a person’s unique abilities, experiences, and behaviors

21
Q

Informed consent (in research)

A

An ethical requirement for all research studies; involves making sure that participants are aware of the purpose and nature of the study, agree to participate freely, and know that they can withdraw at any time

22
Q

Internal validity

A

The degree to which we can conclude that the manipulation of the independent variable in a study (e.g., treatment) caused a corresponding change in the dependent variable (e.g., outcome)

23
Q

Longitudinal study

A

A type of research design that examines the association between variables at different points in time; specifies the temporal relationship between the variables

24
Q

Magnetic resonance imaging (MRI)

A

A neuroimaging method in which a strong magnetic field is used to create a static, detailed image of the body

25
Q

Mediator (variable)

A

A variable that can help explain how two other variables are related; usually a continuous variable

26
Q

Meta-analysis

A

A statistical technique that is used to combine the results of multiple research studies into a single, overall numerical result called an effect size

27
Q

Moderator (variable)

A

A variable that affects the direction or strength of two other variables; usually a categorical variable

28
Q

Nomothetic assessment

A

Data collection that evaluates how groups of people typically think, feel, or act

29
Q

Nonequivalent groups study

A

A type of quasi-experimental study in which researchers compare treatment and control groups, but participants are not randomly assigned to these groups

30
Q

Nonmaleficence

A

An ethical principle that means avoiding harm or inflicting the least discomfort possible to reach a beneficial outcome

31
Q

Open-label study

A

A research design in which participants and researchers know which participants are receiving treatment and which are serving as controls

32
Q

Operational definition

A

A precise description of how a variable in a research study will be measured

33
Q

Parsimony

A

A scientific principle that dictates that simpler explanations should be selected over more complex explanations

34
Q

Placebo effect

A

People’s tendency to alter their behavior simply because they know they are receiving treatment; a threat to the internal validity of a study

35
Q

Precision

A

Care in the manner in which scientists collect data and draw conclusions from their observations

36
Q

Pretest-posttest study

A

A type of quasi-experimental study in which the same group of participants is assessed before and after treatment

37
Q

Pseudoscience

A

Statements, beliefs, and practices that people claim to be evidence based but are incompatible with scientific thinking; based largely on biases, opinions, and appeals to authority

38
Q

Quasi-experimental research

A

A research design that involves the manipulation of an independent variable without the random assignment of participants to groups

39
Q

Random assignment

A

A research method in which each participant has an equal chance of being part of each experimental condition; an essential feature of an experiment

40
Q

Random selection

A

A manner of recruiting participants for a research study in which each person in a given population has an equal chance of being included

41
Q

Randomized controlled trial

A

A special type of experiment used to test the efficacy of treatment; participants are randomly assigned to treatment or control groups

42
Q

Replication crisis

A

Refers to the finding that the results of many scientific studies are difficult or impossible to reproduce

43
Q

Reproducibility

A

Scientific principle that the results of research studies must be replicated before they are accepted

44
Q

Science

A

A set of principles and procedures that are used to guard against biased thinking; relies on the careful, systematic collection of data to understand ourselves and the world

45
Q

Selection bias

A

A systematic difference between participants in the treatment and control groups that can emerge when participants are not randomly assigned; a problem often seen in nonequivalent group studies

46
Q

Single subject study

A

A type of quasi-experimental study in which one participant’s behavior is assessed over time, usually with and without treatment

47
Q

Theory

A

An integrated set of ideas that explain and predict broad aspects of behavior or development

48
Q

Threats to internal validity

A

Characteristics of research studies that limit our ability to make causal inferences: maturation, environmental factors, repeated testing, attrition, and selection bias

49
Q

Treatment as usual (TAU)

A

The most stringent type of control group in which participants are referred to practitioners in the community and receive whatever treatment they provide
