Collaboration and prospective memory: comparing nominal and collaborative group performance in strangers and couples.

Area of Science:

• Cognitive Psychology
• Social Psychology

Background:

• Prospective memory (PM) is crucial for daily functioning.
• The impact of collaboration on PM performance remains largely unexplored.

Purpose of the Study:

• To investigate the effects of collaboration on prospective memory tasks.
• To compare collaboration effects between stranger dyads and intimate couples.

Main Methods:

• Utilized the "collaborative recall paradigm" methodology.
• Participants completed a "Virtual Week" task, either collaboratively or individually.
• Experiment 1 involved stranger dyads; Experiment 2 involved intimate couples.

Main Results:

• Stranger dyads exhibited "collaborative inhibition," performing below pooled individual potential, particularly on easier PM tasks.
• Collaborative inhibition in strangers was linked to both retrospective and prospective memory components.
• Intimate couples showed no significant difference in performance whether collaborating or working separately.

Conclusions:

• Collaboration can incur costs to prospective memory performance.
• Intimate relationships may mitigate the negative effects of collaboration on PM.
• Findings have implications for intervention programs supporting individuals needing PM assistance.
