Quasi-Experimental Designs and Longitudinal & Cross-Sectional Designs

These flashcards cover key vocabulary and concepts around quasi-experimental designs, longitudinal and cross-sectional studies, and other related topics.

Quasi-experimental designs

Research designs having both experimental and control groups but the participants are not randomly assigned.

Nonexperimental vs. Experimental

Nonexperimental designs involve no random assignment or manipulation, while experimental designs involve both.

Non-equivalent control group design

Quasi-experimental designs that employ nonequivalent control groups to compare results without random assignment.

Causal interpretation

Interpretation of results based on whether observed patterns can be attributed to differences between groups or other factors.

Delayed control group design

A design in which the testing of one group is deferred and done separately from another group.

Mixed factorial designs

Research designs that involve both between-subject and within-subject variables.

Interrupted time-series design

A design that compares the same group over time by analyzing trends before and after treatment.

Multiple time-series design

A time-series design that includes both control and experimental groups to rule out rival hypotheses.

Repeated treatment design

A quasi-experimental design that compares responses from the same group before and after treatments.

Longitudinal designs

Research designs that study the same cohort over an extended period, allowing for temporal sequencing.

Cross-sectional designs

Research designs that involve different cohorts being tested at the same point in time.

Selective survival

The phenomenon where individuals who are less competent or adjusted drop out of a study, altering the sample composition.

Practice/retesting effects

Improvement in participant performance due to repeated exposure to the same psychological test over time.

Cohort effect

An effect in research caused by the shared characteristics of a cohort, impacting the independent variable.

Generation

A group of individuals born around the same time, typically affected by similar social and cultural trends.
