Abstract: The Role of Familiarity in Segmentation of Human Action Jessica Kosie University of Oregon Dare Baldwin University of Oregon Abstract: Adults process others’ actions with apparent ease, despite the complexity involved. Expertise seems key, yet lit- tle is known about how expertise alters action processing. Perhaps expertise reshapes how attention is allocated as actions unfold. We investigated this possibility using Hard, Recchia, & Tversky’s (2011) “dwell-time paradigm:” viewers advance through slideshows extracted from a digitized video of an activity sequence, typically displaying a “boundary advantage” (longer dwelling at segment boundaries than mid-segment action) that predicts memory. Participants in our study advanced through slideshows varying in familiarity of action depicted (high, moderate, low) but equated on other dimensions. Systematic dwell-time differences emerged in relation to familiarity: a stronger boundary advantage arose when action was moderately fa- miliar relative to either highly familiar or unfamiliar, pointing to specific expertise-driven changes in how attention is allocated as action unfolds. A theoretical account of these changes offers new insight into fundamental processes subserving fluent action processing.
