Detection and Attention for Auditory, Visual, and Audiovisual Speech in Children with Hearing Loss.

Objectives: Efficient multisensory speech detection is critical for children who must quickly detect/encode a rapid stream of speech to participate in conversations and have access to the audiovisual cues that underpin speech and language development, yet multisensory speech detection remains understudied in children with hearing loss (CHL). This research assessed detection, along with vigilant/goal-directed attention, for multisensory versus unisensory speech in CHL versus children with normal hearing (CNH).

Design: Participants were 60 CHL who used hearing aids and communicated successfully aurally/orally and 60 age-matched CNH.

Developmental Shifts in Detection and Attention for Auditory, Visual, and Audiovisual Speech.

Purpose: Successful speech processing depends on our ability to detect and integrate multisensory cues, yet there is minimal research on multisensory speech detection and integration by children. To address this need, we studied the development of speech detection for auditory (A), visual (V), and audiovisual (AV) input.

Method: Participants were 115 typically developing children clustered into age groups between 4 and 14 years.
