Laboratory eyetrackers, constrained to a fixed display and static (or accurately tracked) observer, facilitate automated analysis of fixation data. Development of wearable eyetrackers has extended environments and tasks that can be studied at the expense of automated analysis. Wearable eyetrackers provide 2D point-of-regard (POR) in scene-camera(More)
The realization of prosody varies across speakers, accents, and speech conditions. Listeners must navigate this variability to converge on consistent prosodic interpretations. We investigate whether listeners adapt to speaker-specific realization of prosody based on recent exposure and, if so, whether such adaptation is rapidly integrated with online(More)
We present an eye-tracking experiment investigating the time course with which listeners derive pragmatic inferences from contextual information. We used as a test case the construction " It looks like an X " pronounced either with (a) a nuclear pitch accent on the final noun, or (b) a contrastive L+H* pitch accent and a rising boundary tone, a contour that(More)
A visual world experiment examined the time course for pragmatic inferences derived from visual context and contrastive intonation contours. We used the construction It looks like an X pronounced with either (a) a H(*) pitch accent on the final noun and a low boundary tone, or (b) a contrastive L+H(*) pitch accent and a rising boundary tone, a contour that(More)
In language-mediated visual search, memory and attentional resources must be allocated to simultaneously process verbal instructions while navigating a visual scene to locate linguistically specified targets. We investigate when and how listeners use object names in visual-search strategies across three visual world experiments , varying the presence and(More)
