Reinforcing Effects of Speech Attributes in Autistic and Mentally Retarded Children.
Frankel, Fred; And Others
The reinforcing properties of language were examined with four autistic and five mentally retarded children matched for mean nonverbal mental age (32-37 months). Ss were shaped to pull a lever which produced 2 seconds of a tape recorded story. The story was read with the following conditions: little pitch variance from word to word, but with normal syllable durations (atonal); each syllable of equal duration, but normal pitch variance (arhythmic); each syllable of equal duration and little pitch variance (flat); and normal syllable duration and pitch variance (normal). Differences in the relative reward values for each of the four conditions confirmed the hypothesis that abnormalities in autistic children's speech result from sources of reinforcement arising in speech production rather than in misperception of speech attributes.
