Studies on teaching tacts to individuals with autism spectrum disorder (ASD) have primarily focused on visual stimuli, despite published clinical recommendations to teach tacts of stimuli in other sensory domains as well. In the current study, two children with ASD were taught to tact auditory stimuli under two stimulus-presentation arrangements:…

The function of consciousness was explored in two contexts of audio-visual speech, cross-modal visual attention guidance and McGurk cross-modal integration. Experiments 1, 2, and 3 utilized a novel cueing paradigm in which two different flash suppressed lip-streams cooccured with speech sounds matching one of these streams. A visual target was…

A series of studies on newborns' abilities for recognizing speaking faces has been performed in order to identify the fundamental cues of social cognition. We used audiovisual dynamic faces rather than photographs or patterns of faces. Direct eye gaze and speech addressed to newborns, in interactive situations, appear to be two good candidates for…

Environmental events produce many sensory cues for identifying the action that evoked the event, the agent that performed the action, and the object targeted by the action. The cues for identifying environmental events are usually distributed across multiple sensory systems. Thus, to understand how environmental events are recognized requires an…

This study investigates the role of perception and sensory motor learning on speech production in L2. Compared to natural language learning, acoustic input in formal adult instruction is deprived of multiple sensory motor cues and lacks the imitation component. Consequently, it is possible that inaccurate pronunciation results from training.…

We live in a multisensory world and one of the challenges the brain is faced with is deciding what information belongs together. Our ability to make assumptions about the relatedness of multisensory stimuli is partly based on their temporal and spatial relationships. Stimuli that are proximal in time and space are likely to be bound together by…

Normal and learning disabled children were presented with visual and auditory items for free and cued recall. Deficits in semantically cued recall for children with one impaired modality originated at presentation time, perhaps because of separate pathways linking the auditory and visual modalities to the semantic system.

Visual speech cues presented in synchrony with discrepant auditory speech cues are usually combined to a surprisingly clear unitary percept that corresponds with neither of the two sensory inputs (the McGurk illusion). This audiovisual integration process is commonly believed to be highly autonomous and robust to cognitive intervention, unlike the…

We report four experiments designed to determine whether visual information affects judgments of acoustically-specified nonspeech events as well as speech events (the "McGurk effect"). Previous findings have shown only weak McGurk effects for nonspeech stimuli, whereas strong effects are found for consonants. We used click sounds that…
