Smaller than expected: Effects of imitative action regulation after experiencing social exclusion. Experimental Psychology, 0, 1-12. doi: Abstract: In two pre-registered studies, we investigated whether processes of imitative action regulation are facilitated after experiencing an episode of social exclusion. We reasoned that imitative action regulation effects should be more pronounced for participants who were socially excluded, providing them with an “automatic means” to socially reconnect with others. Participants played a virtual ball-tossing game to experimentally induce social exclusion or inclusion experiences. Subsequently, pairs of two participants engaged in an observational S-R binding paradigm modeled after Giesen et al. (2014): Participants observed color categorization responses in their interaction partner (trial n-1) and then executed (in-)compatible responses in the subsequent trial (trial n), with observation and responding occurring in alternation. Stimulus relation (repetition vs. change) from trial n-1 to trial n was orthogonally manipulated. In both studies, stimulus-based retrieval effects of observationally acquired SR bindings were descriptively larger in socially excluded (compared with socially included) participants. However, none of the effects were statistically significant. Even a joint analysis of both experiments did not show the expected modulation. Implications for the study of imitative action regulation processes are discussed.
