Bisensory augmentation: A speechreading advantage when speech is clearly audible and intact

Reisberg, McLean, and Goldfield (1987) have shown that vision plays a part in the perception of speech even when the auditory signal is clearly audible and intact. Using an alternative method the present study replicated their finding. Clearly audible spoken messages were presented in audio-only and audio-visual conditions, and the adult participants' resulting comprehension was measured. Stories were presented in French (Expt 1), in a Glaswegian accent (Expt 2), and by presenting spoken information that was semantically and syntactically complex (Experiment 3). Three separate groups of 16 adult female participants aged 19-21 participated in the three experiments. In all three experiments, comprehension improved significantly when the speaker's face was visible.     

Analysis of Live Modeling Plus Prompting and Video Modeling for Teaching Imitation to Children with Autism

Previous researchers have demonstrated that training in imitation can significantly improve the learning capabilities of children diagnosed with autism spectrum disorder (ASD) and that children within this population show a preference for video presentations. Video‐based instruction has been used to teach a variety of behaviors to individuals with ASD. However, only a small number of studies have examined the use of video modeling to teach initial imitation. Furthermore, there are limited and conflicting data on the effectiveness of a video modeling procedure that does not incorporate prompting when used to teach imitation to young children with ASD. Thus, the purpose of this study was to evaluate a video‐modeling‐alone procedure and a live‐modeling‐with‐prompting procedure for teaching imitation to young children with ASD. The results suggest that the live modeling with prompting procedure was more effective, and implications related to this finding are discussed. Copyright © 2015 John Wiley & Sons, Ltd.
