Summary

The aim of the planned online study is twofold. First, it opts to deliver further evidence for the existence of the construct ego-depletion. Second, it tries to further validate the German version of the word-stem completion task as a measure of implicit aggression. The psychological assessment of aggression is not a trivial aspect, however. In general, explicit measures of aggression have a higher face validity than their implicit counterparts. However, even implicit measures, such as the implicit association test for aggression, have a certain amount of face validity, since participants might be able to infer that the task is related to aggression. Another implicit aggression measure is the word-stem completion task, which asks participants to complement word-stems in order to build words. Lately, we have developed a German version of this task and found some promising first results, i.e., a factor analysis indicated that the word-stem completion task explained unique variance in aggression. The present study aims to further validate the German version of the word-stem completion task by experimentally manipulating aggression through an ego-depletion paradigm, in which cognitive resources are depleted. It is expected that participants in the ego-depletion condition build more aggressive solutions on the word-stem completion task than participants in the control group.

Conditions

  • Aggression

Interventions

BEHAVIORAL

Ego-depletion

The surgery video lasts for 9 minutes and participants are asked to suppress their emotions. After the intervention several implicit aggression tests, as well as a task, measuring cognitive performance in general are assessed.

BEHAVIORAL

Control

The surgery video lasts for 9 minutes and participants in the control group are asked to watch the surgery video without the need to suppress their emotions. Several implicit aggression tests, as well as a task, measuring cognitive performance in general are assessed after the 9 minute video sequence.
