On each trial, subjects were played a dichotic pair of syllables differing in the consonant (/ba/, /da/, /ga/) or in the vowel (/ba/, /b?/, /bi/). The pair of syllables was preceded by a melody, or a sentence, and followed by the same or a different melody, or sentence. Subjects either had to retain the first piece of additional material or were free to ignore it. The different combinations of phonemic contrast, additional material, and instruction concerning the additional material were used in different sessions. In each case, the main task of the subjects was to respond to the presence or the absence of the target /ba/ on the ear previously indicated. There was no effect of context on relative ear accuracy, but the right-ear advantage observed for consonants in response latency when subjects retained a sentence gave way to a small nonsignificant left-ear advantage when subjects retained a melody. Right-ear advantage in response latencies was also observed for vowels in the verbal context, but the contextual effect, although in the same direction as for consonants, was very slight. The implications of contextual effects for a theory of the determinants of the auditory laterality effects are discussed. 相似文献

Three patients are described who displayed syntactic writing errors in combination with a motor speech disturbance and impaired motor limb function. Two of the patients had bulbar amyotrophic lateral sclerosis (ALS). Agraphia appeared when verbal communication was no longer possible. Autopsy in one patient disclosed only lesions consistent with ALS. The third patient had palilalia and chorea and, although not aphasic, his written language showed persistent syntactic errors. We hypothesize that the agraphia in these patients occurred because of the combination of disordered feedback from the motor speech apparatus and limbs. 相似文献

Four mentally retarded adolescents who showed little or no expressive or receptive language were given a series of tests to determine if they could respond to meaningful nonlinguistic sounds. The tests required the subjects to respond to sounds on the basis of meaning by classifying the sounds according to the objects which produced them, i.e., the sound sources. The results show that the subject could not classify the sounds on the basis of their source although they could discriminate between them. These results are in contrast to the near perfect classification by another retarded subject who lacked speech due to a motor disorder but, nevertheless, showed good understanding of language. The finding that some nonverbal children have difficulty in responding to the meaning of nonlinguistic sounds suggests the possibility that the failure of these children to develop language may have been due to an agnosia not unlike that found in adult stroke patients. 相似文献

Different groups of rats received different numbers of compound CS (light/noise) conditioning trials in the CER procedure. The amount of suppression evident to the single elements of the compound decreased as a function of the number of previous compound trials. This loss of CR strength was interpreted as a configuring effect. Further experimental comparisons indicated that the configuring effect could not be readily explained in terms of a generalization decrement or a stimulus novelty hypothesis. 相似文献

The language development of three 9- and 10-year-old children possessing only a right or a left hemisphere was studied. Surgical removal of one brain half antedated the beginning of speech, so each child has acquired speech and language with only one hemisphere. Different configurations of language skill have developed in the two isolated hemispheres: phonemic and semantic abilities are similarly developed but syntactic competence has been asymmetrically acquired. In relation to the left, the right brain half is deficient in understanding auditory language, especially when meaning is conveyed by syntactic diversity; detecting and correcting errors of surface syntactic structure; repeating stylistically permuted sentences; producing tag questions which match the grammatical features of a heard statement; determining sentence implication; integrating semantic and syntactic information to replace missing pronouns; and performing judgments of word interrelationships in sentences. Language development in an isolated right hemisphere, even under seizure-free conditions, results in incomplete language acquisition. 相似文献

Following a rise in the life expectancy of cystic fibrosis (CF) patients, many adults with CF form couple relationships. Yet, dyadic coping has not been previously examined in people with CF. This study examined how adults with CF and their partners cope as a couple with the illness, and what meanings each partner and the couple as a unit attribute to the experience. Seventeen adult CF patients and their partners participated in separate semi‐structured in‐depth interviews. Two main patterns of dyadic coping with CF were identified as follows: cooperation and tension. For couples in cooperation, the marital relationship served as a resource for adaptive coping. These couples were characterized by similarities in their perception of the place of CF in their lives and of their roles in the marital relationship. Couples in tension described the couple relationship as strained by difficulty of accepting the disease, proliferation of negative emotions, and a sense of burden and loneliness in the process of coping. Findings point to the importance of mutual empathy, clear and accepted division of roles between the partners, and open communication for facilitating coping as a couple. 相似文献
