DESCRIPTION:Is gaze a window into the cognitive landscape of a viewer? Whi
 le it is well established that visual features of the external environment
  guide attention\, the extent to which gaze reflects our endogenous cognit
 ive priorities remains less clear. Naturalistic contexts are ideal for stu
 dying these endogenous factors\, as individuals must draw on their own con
 ceptual knowledge bases and priorities during active visual selection. In 
 this talk\, I will present two ongoing eye-tracking studies that leverage 
 computational language models to uncover the cognitive priorities guiding 
 gaze in individuals with and without autism in naturalistic contexts. Firs
 t\, in immersive\, real-world environments\, eye-tracking reveals idiosync
 ratic\, trait-like “gaze fingerprints” in individuals with and without
  autism\, which are partly explained by the conceptual feature space of a 
 large language model\, capturing unique variance beyond spatial and vision
 -based models. Second\, in dyadic conversations\, mobile eye-tracking show
 s that gaze to the conversation partner’s face is modulated by the ongoi
 ng semantic context of the exchange\, including linguistic surprisal - wit
 h differences between individuals with and without autism. Together\, thes
 e findings position gaze as a window into the semantic and predictive proc
 esses that shape attention\, providing new leverage for modeling individua
 l differences in natural contexts.
