Seventy-one families from a low socio-economic background, each with a son at risk of developing psychosocial problems at the onset of the study, were observed three times over a six-year period while solving a combinatorial task presented on a microcomputer. The permutations task was used to gather information with regard to cognitive functioning and cognitive self-regulation of the families, which were observed as a developmental unit. Cognitive functioning was assessed according to three variables: cognitive strategies, performance, and completion of the task. Six self-regulatory activities were assessed: task definition, planning, supervision, evaluation, parental support, and sharing of responsibilities. Although inefficient strategies were mainly used across the six years, the cognitive level of functioning improved over the years. Cognitive self-regulatory activities most often used across time were supervision and parental support. Differences were observed in the three time periods for supervision, task definition, parental support, and individual involvement. Results indicated a link between cognitive strategies used by the families to solve the task and their self-regulatory activities. Results are interpreted within both the Piagetian and Vygotskian perspectives. Families' cognitive self-regulatory activities observed in this study are an example of parental disengagement and children's growing involvement in a joint activity. 相似文献

A case of acquired phonological dyslexia is described (P.M.). The patient was encouraged to read nonwords by analogy with real words, i.e., by changing phonemes in real words to produce pronounceable nonwords. P.M. was able to perform this task suggesting that he retained some ability to use grapheme-phoneme conversion rules. On the basis of P.M.'s performance an additional connection in Morton's logogen model is postulated. 相似文献

A model of sentence comprehension postulating that Subject-Verb-Object relations are specified prior to Noun-Adjective relations received support from a study of the speed at which sentences with various kinds of violations could be rejected. Compatible with the sequential model was the finding that Noun-Verb and Adjective-Noun double violations did not result in shorter RTs than Noun-Verb single violations — even though sentences with double violations were judged to be less acceptable. 相似文献

The purpose of this experiment, carried out on 27 subjects with intense and circumscribed fears, was to test one main hypothesis and several subsidiary predictions. The prediction that a high-demand in vivo treatment condition produces desynchronous changes and a low-demand treatment condition synchronous changes, was supported by some inter-session findings but not by the intra-session findings. The clear linear relation between heart-rate and reported fear was confirmed, as was the rapid habituation of the heart-rate response to phobic stimulation.The fear-reactions and fear-reductions of psychiatric and non-psychiatric were indistinguishable. High heart-rate responders and low heart-rate responders showed similar patterns of improvement. The constrained laboratory ‘treatment’ procedure used in the experiment produced large and rapid reductions in fear. 相似文献

Children, ranging in ages from 7.3 to 9.6 years, were identified according to the type of schemata structure they used to recall picture sequence events. These children were then required to recall several written text passages representing four different conditions: (1) theme first paragraphs, (2) theme final paragraphs, (3) paragraphs with no theme but having thematic structure, and (4) paragraphs with no theme and no thematic structure. It was found that the manner and the amount of the child's recall were a function of how the child's schemata structure interacted with a given paragraph structure. The implications of these findings are discussed in terms of the generally unquestioned assumption that only one “ideal” text grammar is needed to describe children's schemata for processing test. 相似文献

In three experiments analyzing determinants of the easy-to-hard effect, pigeons acquired a hard discrimination after training on other problems. Intradimensional pretraining resulted in immediate transfer to the hard discrimination. Extradimensional pretraining consistently did not produce immediate transfer but did facilitate learning rate. In Experiment 1, the compounding of cues from an easy extradimentsional discrimination with those from the hard discrimination resulted in the former overshadowing the latter. When different types of extradimensional discriminations were introduced in Experiments 2 and 3, the degree of transfer was not proportional to the similarity in incidental background cues across problems. The findings indicate that in the easy-to-hard effect: (a) intra- and extradimensional mechanisms jointly contribute to the development of stimulus control, (b) intradimensional transfer is more consistent with the gradient-interaction model than the selective attention model, and (c) extradimensional transfer is better accounted for by the construct of general attentiveness rather than by the neutralization of background cues. 相似文献

Although rats preferentially associate gustatory stimuli with illness, this does not imply that other types of stimuli cannot be associated with illness. In Experiment 1, rats consuming tap water in a distinctive environment prior to illness subsequently suppressed ingestion in that environment, whereas rats poisoned or injected with saline 10 hr later did not. It was also found that rats poisoned after drinking saccharin in the environment paired with illness developed weaker saccharin aversions than identically trained rats which drank saccharin in a different location. In Experiment 2, degrading the correlation between injection-related cues and illness by interpolating saline injections between LiCl preexposures attenuated the decremental effects of illness preexposure. The strength of the exteroceptive cue-illness associations observed in these studies suggests that theories based on evolutionary arguments are not the most appropriate frame of reference for analyzing stimulus selection in poison-induced avoidance. 相似文献

A phoneme discrimination test based upon CCVC (consonant-consonant-vowel-consonant) syllables was administered to 36 aphasics, 91 brain-damaged subjects, and 42 normal controls, in normal listening conditions. Errors in the discrimination of voice and place contrasts were determined, and the scores (voice-minus-place errors) obtained by the four experimental groups were compared statistically. Aphasic patients, when compared with the other groups, show a greater difficulty in discriminating place than voice contrasts. Some implications of these findings are discussed. 相似文献
