Mnemonic similarity and convergence scores. a The increase in mnemonic convergence from pre-conversation to post-conversation was larger in the Bridge Ties First condition (M = 0.22; SD = 0.03) than in the Cluster Ties First condition (M = 0.18; SD = 0.03), t(10) = 2.21, p = 0.052, Cohen’s d = 1.28, confidence interval (CI) [0.00, 0.07]. b The increase in mnemonic similarity from pre- to post-conversation was larger in the Bridge Ties First condition than in the Cluster Ties First condition for participants who were part of the same cluster (MBridgeTies = 0.27, SDBridgeTies = 0.02 vs. MClusterTies = 0.21; SDClusterTies = 0.03; t(10) = 3.43, p = 0.006, Cohen’s d = 2.10, CI [0.02, 0.09]) and marginally significant for participants in neighboring clusters (MBridgeTies = 0.21, SDBridgeTies = 0.04 vs. MClusterTies = 0.17; SDClusterTies = 0.03; t(10) = 2.11, p = 0.061, Cohen’s d = 1.11, CI [0.00, 0.08]), but not for those in distant clusters (p = 0.39). All comparisons involve independent-sample t-tests. In this figure, boxplots show interquartile range (box), mean (black line within interquartile range), and data range (vertical lines)
