Very long term memory for abstract materials was examined by recalling subjects who had served in a synthetic grammar learning experiment two years earlier. In that study (Reber & Allen, 1978) we differentiated among several cognitive modes of acquisition, their resultant memorial representations, and their associated decision processes. Two years later and without any opportunity for rehearsal or relearning, subjects still retain knowledge of these grammars to a remarkable degree. Although some differences have become blurred with the passage of time, the form and structure of that knowledge and the manner in which it is put to use remain strikingly similar to the original. That is, differences traceable to acquisition mode and conditions of initial training can still be observed. As in the original study, these results are discussed within the general context of a functionalist approach to complex cognitive processes. 相似文献

Fifty students from each of the grades 2, 4, 6, 8, 10, and 12 were asked to complete a questionnaire containing the following three questions: 1) What is stuttering? 2) What is stammering? 3) How did you know that? Analysis of their responses indicated students were more familiar with stuttering as opposed to the term stammering. From grade 6 onward, we can expect at least three-fourths of the students to define stuttering as a disruption of speech consisting chiefly of sound or syllable repetitions. Only about one-fourth of students in grade 6 and above defined stammering as a speech disruption. This disruption was characterized chiefly by repetitions, injections, and pauses. Most of the students were unable to specify how they learned the definitions. The few who did identified family and friends as their chief source of knowledge. 相似文献

The performances of 22 adult stutterers and 22 adult nonstutterers on motor tasks requiring the graphic reproduction of a sequence of alternating figures following the production of a series of nonalternating figures were studied. The finding that there were no differences in the performance of the two groups on the alternating motor tasks was interpreted as challenging the validity of previous observations that motor perseverative behavior exists in stutterers and is indicative of a central neurological deficit in that population. 相似文献

Alpha hemispheric asymmetries of nonstuttering males, nonstuttering females, and stuttering males were explored with electroencephalographic procedures during exposure to two lists of one-syllable words which the subjects were required to recall following presentation. One word list contained low-imagery words while the other contained high-imagery words. Stuttering males were found to have significantly less alpha in their right hemispheres, suggesting right hemispheric processing strategies. This finding was interpreted as supporting the “segmentation dysfunction” explanation of stuttering suggested by Moore and Haynes (1979b). Nonstuttering males showed less left than right alpha while nonstuttering females revealed no difference between their right and left hemispheres. Differences between nonstuttering males and females are discussed as being task and stimuli dependent relative to the segmental/nonsegmental nature of both task and stimuli. Differential hemispheric asymmetries for words of high or low-imagery were not observed. 相似文献

This paper outlines portions of the writer's therapeutics in the field of stuttering with emphasis upon use of masking the hearing of stutterers as a part of a total therapeutic approach. Commencing with devices providing continuous noise to override the voice of the stutterer so that he cannot hear himself and, thus, eliciting fluency. Described is the use of the voice actuated Edinburgh Auditory Masker within an intensive stuttering program in a prison setting since September 1978. It is concluded that the use of masking and the Edinburgh device has been helpful and productive with severe stutterers. 相似文献

Do cognitive abilities in early childhood relate genetically and/or environmentally to isomorphic abilities in adulthood? Are specific cognitive abilities diffentiated in early childhood in terms of their prediction of adult cognitive abilities? The present study, the first behavioral genetic analysis of specific cognitive abilities in early childhood, explored these questions using parent-offspring data for 186 adopted children and 151 nonadopted children tested in the longitudinal Colorado Adoption Project at 3 years of age and 162 adopted children and 138 nonadopted children tested at 4 years. The children's Stanford-Binet IQ and scores for four specific cognitive abilities (verbal, spatial, perceptual speed, and memory) were correlated with corresponding measures for their parents—the biological and adoptive parents of the adopted children and the natural parents of the nonadopted children. Significant correlations were found between biological mothers' IQ and the IQ of their adopted away offspring at 3 and 4 years of age, suggesting genetic influence for IQ. However, specific cognitive abilities yielded no significant correlations between biological mothers and their adopted-away offspring. These results suggest that substantial genetic continuity exists for IQ from early childhood to adulthood, but not for specific cognitive abilities. 相似文献

The method of vibrotactile mangitude production scaling was used to determine the tactile sensory-perceptual integrity for the dorsum of the tongue and thenar eminence of the right hand for 10 fluent speakers and 10 stutterers. It was discovered that both groups performed the task in a similar manner for the thenar eminence of the hand (a nonoral structure) but in a dissimilar manner for the tongue (an oral structure). From these data, it is suggested that the stutterers may maintain a different internal sensory-perceptual process for the tactile system involved in the speech process. The possibility exists that stuttering, for some, may be an “internal disorder” of the tactile-proprioceptive feedback mechanism that is directly involved in speech production. 相似文献

The ultimate test of the adequacy of linguistic models of fluency breakdown is the degree to which they may account for patterns of dysfluency in the speech of a stutterer who is fluent in more than one language. We present the case of an adult bilingual stutterer (Spanish-English), whose spontaneous language in both Spanish and English was structurally analyzed to assess the relationships of phonological and syntactic structure to the frequency and location of fluency breakdown. Our findings suggest that syntax is probably a greater determinant of stuttered moments than is phonology. Additionally, similarities and differences between English and Spanish sentence structure were associated with similarities and differences in the loci of dysfluencies across the two languages. The need for crosslinguistic research utilizing monolingual and bilingual speakers of languages other than English is emphasized. 相似文献
