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. 相似文献

Developmental differences among the effectiveness of three spoken reinforcers were evaluated by measuring rate and accuracy of performance on a vowel recognition task. Eighty-seven males were selected from grades 1 to 3, 6 to 7, and 11 to 12 of a predominantly urban, Black, parochial school. The effectiveness of approval and affirmation of correctness was related to grade level for accuracy of performance, but not for rate. For accuracy of performance a decreasing linear trend was found when approval effectiveness was evaluated across grades. For correctness, an increasing linear trend was found. The results were discussed in terms of a developmental hierarchy of reinforcers and information processing. 相似文献
