Comprehension and Imitation of Sentences by Mongoloid Children as a Function of Transformational Complexity. Studies in Language and Language Behavior, Progress Report Number VII.
Semmel, Melvyn; Greenough, Diane
The effect of sentence complexity on the ability of 40 trainable mentally retarded mongoloids (median IQ 34.3) to comprehend and imitate verbally presented strings was examined in two studies. Comprehension ability was tested by asking each subject to indicate which of two pictures was being described in the sentence spoken by the examiner. Eight stimulus sentences were given for each pair of pictures, simple declarative or kernel, negative, passive, and negative passive. Kernel sentences were comprehended significantly more often than chance expectancy (p .08) but negative sentences less often than chance (p .02). Imitation of kernel sentences (obligatory transformations only) was significantly better than imitation of sentences in which optional transformations had been applied (p .05). No significant differences in accuracy of imitation were observed among the strings with optional transformations. Competence and performance variables were considered to affect the ability of trainables to deal with verbal stimuli and further studies emphasizing the negative marker are recommended. (Author)
