Brief Summary

Research has shown that people with depressive symptoms maintain negative expectations even if they have positive experiences that contradict their expectations. Healthy people, however, change their expectations after unexpected positive experiences. In this experimental study, it will now be examined whether there are also differences between healthy people and people with depressive symptoms in dealing with unexpected negative experiences.

Conditions

Major Depressive Disorder

Outcome Measures

Primary Outcomes (1)

• 2-Item Performance Expectations Scale - generalized

  Changes from baseline to postassessment in generalized performance expectations. Each item is scored from 1 to 7 (1 = very negative expectations, 7 = very positive expectations), yielding a total score between 2 and 14. Higher total scores reflect more positive expectations.

  Immediately before the performance test and immediately after completion of the performance test

Secondary Outcomes (1)

• 2-Item Performance Expectations Scale - task-specific

  Immediately before the performance test and immediately after completion of the performance test

Other Outcomes (1)

• 5-Item Cognitive Immunization after Performance Feedback (CIPF) scale

  Immediately after completion of the performance test

Study Arms (2)

Expectation confirmation

EXPERIMENTAL

The participants in this group receive manipulated feedback indicating that their performance was very good in the test they had previously worked on. This feedback is intended to confirm the previously induced positive expectations of their own performance.

Behavioral: Expectation confirmation

Expectation disconfirmation

EXPERIMENTAL

The participants in this group receive manipulated feedback indicating that their performance was below average in the test they had previously worked on. This feedback is intended to negatively disconfirm the previously induced positive expectations of their own performance.

Behavioral: Expectation disconfirmation

Interventions

Expectation confirmation BEHAVIORAL

Participants receive manipulated feedback indicating that their performance was above average in the test they had previously worked on. This feedback is intended to confirm the previously induced positive expectations of their own performance.

Expectation confirmation

Expectation disconfirmation BEHAVIORAL

Participants receive manipulated feedback indicating that their performance was below average in the test they had previously worked on. This feedback is intended to negatively disconfirm the previously induced positive expectations of their own performance.
