Design outcomes

Primary

MeasureTime frame
The aim of the project is to experimentally investigate how social inclusion, compared to social exclusion (ostracism), affects the degree of empathy. Empathy is operationalized indirectly through prosocial behavior and measured based on the amount of money distributed in an adapted Dictator Game. Endpoints/Outcomes: Prosocial behavior, operationalized via the amount of money allocated in the Dictator Game. Definition: The amount of money (in monetary units) that a participant allocates to another person (external allocation) following the Cyberball manipulation.

Secondary

MeasureTime frame
1. Manipulation Check – Subjectively Perceived Social Exclusion Definition: Perception of exclusion in the Cyberball game. 2. Moderation by Personality Traits (Big Five, NEO-FFI-30) Definition: Interaction between experimental condition (inclusion vs. exclusion) and personality on prosocial behavior. 3. Trait empathy (SPF-IRI) Definition: Participants’ dispositional empathy.
