Collaborative inhibition persists following social processing

Abstract

In this experiment, participants read target words that were presented in the context of a social sentence “Willow towered over Meadow” or a nonsocial sentence “The willow towered over the meadow.” Subsequently, they received a surprise cued recall test for the target nouns/names and completed the test either alone or in a group of two. Despite the fact that the stimulus materials were held constant across conditions, participants showed a social processing advantage in memory—that is, they remembered the social (name) versions of the target words significantly better than the nonsocial (noun) versions. Further, the social benefit was not strong enough to neutralise the inhibitory effects of collaboration as collaborative groups (two people working together) recalled significantly fewer words than did nominal groups (combined, nonredundant, output of two individuals working separately). The present study also demonstrated robust collaborative inhibition with cued recall, a task previously assumed to eliminate such inhibition.
