Social Psychology Definitionen

Repeating a scientific study to check whether its results can be obtained again.
 

Replication in which a study is repeated as exactly as possible.
 

Replication in which some change is introduced to the method of the original study.

Different causes may interact with each other to produce changes in a dependent variable (e.g., contact between groups and equality of status between groups interact to predict reductions in prejudice).

When the effect
of one variable (e.g., contact between groups) on an outcome (e.g., prejudice)
is changed by a third variable (e.g., whether groups are equal in status). Moderation is apparent when an interaction effect is observed.

When the effect of one variable (e.g., contact between groups) on an outcome (e.g., prejudice) works through an intermediate variable (e.g., anxiety about interactions with the other group).
