Based on previous findings regarding the effects of grammatical aspect on intentionality and temporal dynamics (e.g., Eerland et al., 2016; Madden & Zwaan, 2003; Magliano & Schleich, 2000; Sherrill et al., 2015), we hypothesize that
1) participants who read the imperfective aspect vignette will judge Mark to be more to blame for the scuffle than participants who read the perfective aspect vignette.
2) participants who read the imperfective aspect vignette will judge Mark to be more to blame for the injury than participants who read the perfective aspect vignette.
3) participants who read the imperfective aspect vignette will think that Mark punched John more times than participants who read the perfective aspect vignette.
4) effects of grammatical aspect on blame judgments will be mediated by the effect of temporal dynamics. This prediction is consistent with Sherrill et al. (2015).
