      abstract     = {AbstractBackground: Humans form almost instantaneous
                      impressions of everyone they encounter. These impressions
                      set the first tone for how they approach and interact with
                      others. Research on impression formation unveiled that
                      impressions formed by autistic and non-autistic people are
                      often less favourable when rating an autistic person. This
                      effect is partly explainable by differences in motion
                      dynamics.Methods: In this preregistered study, we
                      systematically assessed impressions formed by 27 autistic
                      and 36 non-autistic comparison observers when watching
                      videos showing silent interactions between either two
                      non-autistic or between an autistic and a non-autistic
                      person. We used an eye tracker to capture their gaze
                      patterns while observing these interactions. Of each dyadic
                      interaction, video vignettes with high and vignettes with
                      low interpersonal synchrony of movement (IPSmov) were
                      extracted using Motion Energy Analysis so that we could
                      investigate the effects of interpersonal synchrony and
                      diagnosis, respectively.Results: Interactions were rated
                      less favourably when the observed dyad included an autistic
                      adult. Additionally, interactions showing low IPSmov were
                      rated less favourably than interactions showing high IPSmov,
                      regardless of dyad type. Both autistic and comparison
                      observers rated interactions of non-autistic dyads and high
                      IPSmov interactions more favourably. Gaze patterns revealed
                      differences between autistic and comparison observers, but
                      no differences due to IPSmov or dyad type. Furthermore,
                      dwell times to hands predicted ratings.Limitations: In this
                      study, we investigated specific influences on impression
                      formation, specifically interpersonal synchrony of movement
                      and autism. There are many more potentially interesting
                      aspects of individuals that impact impression formation,
                      such as facial expressiveness, gaze behaviour and linguistic
                      content of conversations, which should be investigated
                      systematically and in a controlled fashion in future
                      research.Conclusions: Extending research on autism and
                      impression formation to dyadic interactions, this study
                      reveals that motion dynamics play a role in how pleasant
                      interactions are perceived. Autistic-involved interactions
                      were rated lower, despite observers being unaware of the
                      dyad type and only watching people's outlines. Future
                      research should identify conversational aspects driving
                      lower ratings of mixed dyads, potentially considering the
                      effect of hand dwell times on ratings. Autistic and
                      comparison observers showed different gaze patterns despite
                      similar ratings, confirming distinct social information
                      processing.Keywords: Autism spectrum disorder; Behavioural
