Vocabulary

Conceptual replication

A replication that investigates the relationship between the same conceptual variables that were studied in previous research but tests the hypothesis using different operational definitions of the independent variable and/or the dependent variable.

Constructive replication

A replication that investigates the same hypothesis as the original experiment (either in the form of an exact or a conceptual replication) but also adds new conditions to the original experiment to assess the specific variables that might change the previously observed relationship.

Exact replication

Research that repeats a previous research design as exactly as possible, keeping al most everything about the research the same as it was the first time around.

External validity

The extent to which the results of a research design can be generalized beyond the specific settings and participants used in the experiment to other places, people, and times.

Field experiments

Experimental research designs that are conducted in a natural environment such as a library, a factory, or a school rather than in a research laboratory.

Generalization

The extent to which relationships among conceptual variables can be demonstrated in a wide variety of people and with a wide variety of manipulated or measured variables.

Inclusion criteria

The rules that determine whether a study is to be included in a meta analysis.

Meta-analysis

A statistical technique that uses the results of existing studies to integrate and draw conclusions about those studies.

Moderator variable

A variable that produces an interaction of the relationship between two other variables such that the relationship between them is different at different levels of the moderator variable.

Participant replication

A replication that tests whether the findings of an existing study will hold up in a different population of research participants.

Replication

The repeating of research, either exactly or with modifications.

Research programs

Collections of experiments in which a topic of interest is systematically studied through conceptual and constructive replications over a period of time.

Review paper

A document that discusses the re search in a given area with the goals of summarizing the existing findings, drawing conclusions about the conditions under which relationships may or may not occur, linking the research findings to other areas of research, and making suggestions for further research.
