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)
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)
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)
Electroencephalography (EEG) has been used as a method of diagnosis and observation for patients with seizure disorders. However, it is often difficult to collect reliable and accurate data due to the relatively sensitive nature of most EEG hardware. This research is to construct an EEG acquisition system and interface it with a Wireless Sensor Network. The(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)
Atkinson (Reports, 15 April 2011, p. 346) argues that the phonological complexity of languages reflects the loss of phonemic distinctions due to successive founder events during human migration (the serial founder hypothesis). Statistical simulations show that the type I error rate of Atkinson's analysis is hugely inflated. The data at best support only a(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)
