Negative Priming in a Joint Selection Task 1 2 Timothy N. Welsh *, Laura M. McDougall 1 Faculty of Kinesiology and Physical Education, University of Toronto, Toronto, Ontario, Canada, 2 Faculty of Kinesiology, University of Calgary, Calgary, Alberta, Canada Abstract Recent studies have suggested that the observation of another individual executing a movement activates representations of the observed movement in the observer. These representations are thought to be used by other systems to facilitate a variety of social cognitive processes, such as social searches. Previous research on social searches has primarily involved contexts where targets were presented in isolation. Typical environments, however, contain targets and non-targets and one must select the correct information for task completion. To gain insight into the processes underlying social searches, participants completed negative priming tasks alone and in pairs. Results indicated that there were no differences in the negative priming effects resulting from the participants observed or performed the preceding selection task. Further, the correlations between individual and joint negative priming suggest that similar processes were activated on these tasks. The findings support the co-representation hypothesis and provide insight into the processes underlying selection in individual and social settings.
