Is inclusion a valid control for ostracism?

Area of Science:

• Psychology
• Social Psychology
• Human-Computer Interaction

Background:

• Cyberball, an online game, is widely used to study social ostracism.
• The standard Cyberball inclusion condition serves as a control for ostracism.
• The adequacy of this control is questioned without a true no-inclusion baseline.

Purpose of the Study:

• To introduce and validate Cybertree, a novel control condition for social exclusion research.
• To compare Cybertree with the standard Cyberball inclusion and ostracism conditions.
• To clarify the effects of inclusion versus ostracism on psychological states.

Main Methods:

• Development of Cybertree, a control paradigm simulating Cyberball's experience without social inclusion.
• Experimental comparison of participant experiences across three conditions: Cyberball ostracism, Cyberball inclusion, and Cybertree.
• Measurement of ostracism perception, need satisfaction, and mood.

Main Results:

• Participants in the Cybertree condition reported similar levels of ostracism, need satisfaction, and mood as those in the Cyberball inclusion condition.
• Both Cyberball inclusion and Cybertree conditions showed significantly different outcomes compared to the Cyberball ostracism condition.
• No significant differences were found between Cyberball inclusion and Cybertree in key psychological measures.

Conclusions:

• The standard Cyberball inclusion condition is a reasonable and effective control for Cyberball-induced social ostracism.
• Cybertree offers a valuable alternative control, particularly for research questions requiring a distinct no-inclusion baseline.
• The findings refine our understanding of control conditions in social exclusion research and their impact on need satisfaction.
