Word frequency is one of the strongest determiners of reaction time (RT) in word recognition tasks; it is an important theoretical and methodological variable. The Ku?era and Francis (1967) word frequency count (derived from the 1-million-word Brown corpus) is used by most investigators concerned with the issue of word frequency. Word frequency estimates from the Brown corpus were compared with those from a 131-million-word corpus (the HAL corpus; conversational text gathered from Usenet) in a standard word naming task with 32 subjects. RT was predicted equally well by both corpora for high-frequency words, but the larger corpus provided better predictors for low- and medium-frequency words. Furthermore, the larger corpus provides estimates for 97,261 lexical items; the smaller corpus, for 50,406 items. 相似文献

Forty college students were taught facilitated communication via a commercially available training videotape. They were then asked to facilitate the communication of a confederate, who was described as developmentally disabled and unable to speak. All 40 participants produced responses that they attributed at least partially to the confederate, and most attributed all of the communication entirely to her. Eighty-nine percent produced responses corresponding to information they had received, most of which was unknown to the confederate. Responding was significantly correlated with simple ideomotor responses with a pendulum and was not affected by information about the controversy surrounding facilitated communication. These data support the hypothesis that facilitated communication is an instance of automatic writing, akin to that observed in hypothesis and with Ouija boards, and that the ability to produce automatic writing is more common than previously thought. 相似文献

The effectiveness of matching the conceptual structure of participants in educational training and psychotherapy experiences has been demonstrated in previous research. This paper describes an attempt to test the effectiveness of this model in a school desegregation workshop designed to promote a mandatory bussing proposal by a local school board. Differentiation matching had little effect on participants' global judgments of satisfaction with workshop goals but was significantly and inversely related to the decision to voluntarily bus a child, especially among blacks. Abstractness of topics discussed affected participant endorsement of workshop goals but did not affect bussing decision. The findings suggest that how such workshops are organized is dependent on whether the workshop success is to be evaluated on the basis of community public relations or actual decisions to bus children. 相似文献

Immediate echolalia, a common language disorder in psychotic children, was studied in a series of replicated single-subject designs across six schizophrenic and five normal children. In Experiment 1, each child was presented with several questions and commands, some of which set the occasion for specific, appropriate responses and some of which did not. The former were referred to as discriminative stimuli and the latter, as neutral stimuli. The psychotic children tended to echo the neutral stimuli while responding appropriately to the discriminative stimuli; the normal children, in contrast, typically echoed neither type of stimulus. In Experiment 2, three psychotic children were taught appropriate responses to each of several neutral stimuli. Following this training, the children generally responded appropriately to these stimuli without echoing. A plausible interpretation of these results is that the neutral stimuli were initially incomprehensible or meaningless to the children (whereas the discriminative stimuli were comprehensible or meaningful) and that verbal incomprehensibility may be one important determinant of immediate echolalia. Finally, the results are noteworthy in that they isolate a sufficient treatment variable (i.e., the reinforcement of alternative, nonecholalic responses) for eliminating instances of this language anomaly. 相似文献

Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular condition with degeneration of the anterior horn cells in the spinal column. Five SMA subtypes exist with classification dependent upon the motor milestones achieved. Study of the SMN1 (survival motor neuron) and SMN2 genes as well as the concepts of the “2?+?0” carriers, gene conversion, de novo mutations and intragenic mutations allow for a better understanding of SMA. Detailing the carrier and diagnostic testing options further deepens the genetic counselor’s knowledge of SMA. A review of care guidelines and research options is included as this information gives a patient a well-rounded view of SMA. Although SMA is most commonly associated with the SMN1 gene, a number of spinal muscular atrophies not caused by genetic changes in this gene may be included as differential diagnoses until confirmatory testing can be completed. SMA is a complex condition requiring a detailed knowledge on the genetic counselor’s part in order to explain the disorder to the patient with clarity thus facilitating increased communication and decision making guidance with the patient. 相似文献

Evidence for the effectiveness of family therapy and family-based interventions from critical literature reviews and controlled trials is considered for families with children and adolescents who present with various difficulties. The evidence supports the effectiveness of family therapy as an effective treatment either alone or as part of a multimodal or multisystemic treatment programme for child abuse and neglect, conduct problems, emotional problems and psychosomatic problems. Implications for practice, training and continuing professional development in the field of family therapy are discussed. 相似文献

To assess the sensitivity and specificity of clinical rating scales from the Beavers, McMaster and Circumplex models of family functioning videotapes of sixty families engaging in a standardized family task interview were rated using the three rating scales. The sixty families included twenty containing a child with an emotional disorder, twenty containing a child with a mixed disorder of emotions and conduct, and twenty in which none of the children presented with clinically significant difficulties. The three rating scales accurately classified 85-90% of normal controls, 70-90% of cases containing a child with a mixed disorder of emotions and conduct, and 55-65% of families containing a child with an emotional disorder. On the rating scales, the Beavers and McMaster models showed particularly high levels of sensitivity in detecting clinical cases, whereas the Circumplex rating scale was particularly good at classifying non-clinical cases accurately. 相似文献
