Environmental Learning of Social Cues: Evidence From Enhanced Gaze Cueing in Deaf Children.

The susceptibility to gaze cueing in deaf children aged 7-14 years old (N = 16) was tested using a nonlinguistic task. Participants performed a peripheral shape-discrimination task, whereas uninformative central gaze cues validly or invalidly cued the location of the target. To assess the role of sign language experience and bilingualism in deaf participants, three groups of age-matched hearing children were recruited: bimodal bilinguals (vocal and sign-language, N = 19), unimodal bilinguals (two vocal languages, N = 17), and monolinguals (N = 14).

Multisensory Interference in Early Deaf Adults.

Multisensory interactions in deaf cognition are largely unexplored. Unisensory studies suggest that behavioral/neural changes may be more prominent for visual compared to tactile processing in early deaf adults. Here we test whether such an asymmetry results in increased saliency of vision over touch during visuo-tactile interactions.

Spatial and non-spatial multisensory cueing in unilateral cochlear implant users.

In the present study we examined the integrity of spatial and non-spatial multisensory cueing (MSC) mechanisms in unilateral CI users. We tested 17 unilateral CI users and 17 age-matched normal hearing (NH) controls in an elevation-discrimination task for visual targets delivered at peripheral locations. Visual targets were presented alone (visual-only condition) or together with abrupt sounds that matched or did not match the location of the visual targets (audio-visual conditions).
