Conditions
Brief summary
Participants will be randomly allocated to one of two experimental conditions: social exclusion or social inclusion. Participants, but not experimenters will be blind to the assignment. Pre- and post-tests will be administered. Participants will be offered 7 euros in compensation for participating.

SINGLE (Subject)
Masking description
Only participants will be masked to the assigned condition. The researcher has to be aware of the assigned condition to prepare the experimental task accordingly.
Intervention model description
The two conditions, based on the experimental task called Cyberball, will be: social inclusion and social exclusion.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Anger State from baseline to end of the experiment | The STAXI-2 will be administered twice: at Baseline and at the same day of Baseline assessment just after the experimental task (end of study) | The STAXI-2 includes a measure of anger state (15 items) with responses ranging from 1=Absolutely not to 3=A lot |
| Trait Injustice | This measure will be administered at Baseline | The Trait Injustice Experiences Questionnaire is a measure of perceived trait injustice beliefs that has 12 items, with responses ranging from 0=never to 4=always. This measure will be used as moderator of the effects of the experiment on anger |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Frustration Discomfort Scale | This measure will be administered at Baseline | This is a measure of frustration intolerance. The scale has 28 items that are gouped in 4 subscales. Items have a 1-to-5 response scale ranging from nothing to a lot. In addition to trait injustice, this measure will also be used in secondary analyses as a moderator of the effects of the experiment on anger |
| Change in State Injustice from baseline to end of the experiment | This measure will be administered twice: at Baseline and at the same day of Baseline assessment just after the experimental task (end of study) | The State Injustice Experiences Questionnaire is a measure of perceived state injustice beliefs that has 12 items, with responses ranging from 0=never to 4=always. This measure will be used as an experimental check (whether exclusion in the experiment effectively increased the sense of injustice in the short term) |
| Change in State Anxiety from baseline to end of the experiment | This measure will be administered twice: at Baseline and at the same day of Baseline assessment just after the experimental task (end of study) | The STAI-S is a measure of perceived state anxiety that has 20 items, with responses ranging from 0=not at all to 3=a lot. This measure will be used as an experimental check (whether exclusion in the experiment effectively increased anxiety in the short term) |
| Cyberball Experiences post-experimental check Questionnaire | This measure will be administered at the same day of Baseline assessment just after the experimental task (end of study) | In addition to exploring the effects of the experimental task on anxiety and anger, the Cyberball includes a measure of impact of the task on perceived inclusion and related concepts (isolation, belonging, perceived number of passes received, etc.). This will also be used as an experimental check |
