Message therapy is a clinical procedure designed to be used as a carry-over technique with school-age stutterers or as a sole technique with the preschooler. The focus of therapy is on a unit of communication rather than on the moment or place of stuttering. One of the basic assumptions of the procedure is that the child is beginning to monitor how he/she is speaking rather than what is being communicated (i.e., the “message”)—each task requiring a different cognitive process. The emphasis of the therapy is to redirect the child's attention to “what he/she is saying.” The clinical procedures are discussed as they relate to the specific population.  相似文献

The accuracy and response latency of absolute frequency judgments were measured as a function of test lag (the number of intervening items between presentations of a test item) in a continuous memory task. Frequency was varied from one to three presentations in Experiments 1 and 2 and from one to five presentations in Experiment 3. The proportion of correct responses decreased as frequency increased, and correct mean response time tended to increase with frequency. Both accuracy and correct mean response time were found to be largely a function of the most recent test lag. The lag-latency functions were best described by piecewise linear functions, with the breakpoint occurring between lags 1 and 2. Continuous frequency estimation was also shown to improve with extended practice. The implications of the results are discussed with reference to trace strength, numerical-inference, and multiple-trace theories of frequency discrimination.  相似文献

The performance of poor and normal sixth-grade readers was compared on an auditory short-term memory task in two studies. In the first study, the effects of distraction, list length, and speed of stimulus presentation were investigated to test the hypothesis that the performance of the poor readers is affected by deficits in selective attention. Group differences in performance, however, were obtained for both distraction and no-distraction conditions. The second experiment examined the hypothesis that group differences may reflect differences in the use of rehearsal. In the second experiment, half the reading-disabled children and half the controls were provided with rehearsal training prior to completing the same short-term memory task a second time. Rehearsal training resulted in improved performance relative to children who were not trained; however, there was no rehearsal training x reading group interaction. The poor readers continued to show deficits in performance relative to the performance of control children. The results of these two studies suggest that deficits observed for poor readers on short-term memory tasks may reflect processing difficulties in some area that precedes rehearsal and affects performance under both distraction and no-distraction conditions.The authors wish to express their thanks to the Sachem School District and Betty Gould, Nicholas Opinanate, and Guy Barber for their unlimited cooperation, and to John Neale for very helpful discussions of a number of issues in this paper.  相似文献

A schedule-induced behavior paradigm was used to investigate the activity patterns of hyperactive children in a standardized situation. In Experiment I, 10 hyperactive and 10 normal control children matched for age, sex, and IQ were observed under conditions of baseline and schedule. Measures of a number of categorized activities were taken on a time-sampling basis. Hyperactive children were more active than controls in baseline and did not respond to the schedule, unlike the controls who became significantly more active in schedule conditions. In Experiment II, 12 hyperactive and 6 normal children were again subjected to the same experimental paradigm, but in two of the four experimental sessions the stimulant drug methylphenidate was administered in an attempt to reduce the amount of baseline activity. Results were substantially similar to those of Experiment I, with hyperactive children more active than controls in baseline and insensitive to the schedule. There was no overall effect of drug administration on the behavior of either group. There were some ratedependent effects of both drug and schedule conditions.  相似文献

The purpose of this paper is to provide a rationale for making broader educational use of peer learning principles as explicated in developmental theory and research. The paper argues that peer learning brings with it unique motivational and cognitive benefits for participating peers. Research has shown that peer learning can bolster children's self-esteem, awaken their interest in challenging tasks, enhance scholarly achievement, and foster prosocial behavior. In particular, it is an effective means of enabling children to grasp basic concepts that underlie school curricula.Two different forms of peer learning, “peer tutoring” and “peer collaboration,” are distinguished. Each has its potential use: peer tutoring for transmitting information and drilling special skills; peer collaboration for facilitating intellectual discovery and the acquisition of basic knowledge.Some general guidelines for the integration of peer tutoring and peer collaboration in the classroom are offered. It is recognized that specific curriculum plans implementing these guidelines must be formulated with a view to the overall cultural context of the school system. Such plans must be molded in context to suit the needs of each particular site. It is concluded, however, that the general principles of peer education set forth in this position paper would enhance all varieties of schooling. As explicated in this article, peer education complements rather than supplants adult teaching, freeing up teachers' time and attention and enabling them to focus more directly and effectively on individual children's learning needs.  相似文献

Reports of learning from 119 participants of 18 general psychodynamic groups from the 1981 and 1982 annual meetings of the Canadian Group Psychotherapy Association were investigated. Two main learning factors emerged from a factor analysis of participant ratings, learning about oneself in a small group (factor one) and learning how to be an effective leader with professional skills (factor two). Participants reported moderate to considerable learning for both factors even though the stated task of the groups did not emphasize the learning of professional skills. Relationships between several classes of variables (group, leader, demographic) and reported learning were studied. Results that were consistent with several previous investigations were found. The discovery of a participant, sex-difference finding, i.e., greater reported learning by the women, generated a number of questions that may be addressed in future investigations.This article was derived from a paper presented at the Fourth Annual Meeting of the Canadian Group Psychotherapy Association, October 27, 1983, Banff, Canada.  相似文献

In September 1981, a symposium of distinguished mental health practitioners from various clinical, administrative, research, and legal disciplines was conducted on the topic of “Behavioral Science and the Secret Service,” under the sponsorship of the National Academy of Sciences, Institute of Medicine. The article combines a study of the symposium's written conference summary, the author's experience as legal counsel to a state security hospital, and research into federal cases that have interpreted the so-called “Presidential Threat Statute” (18 USC 871) in order to discuss the role of the Secret Service in protecting elected federal officials from physical harm. The potential for increasing practical cooperation between the Service and state mental health systems is also discussed.  相似文献

The development of the ability to anticipate—as manifested by preparatory actions and neural activation related to the expectation of an upcoming stimulus—may play a key role in the ontogeny of cognitive skills more broadly. This preregistered study examined anticipatory brain potentials and behavioral responses (reaction time; RT) to anticipated target stimuli in relation to individual differences in the ability to use goals to direct action (as indexed by measures of executive function; EF). A cross-sectional investigation was conducted in 40 adults (aged 18–25 years) and 40 children (aged 6–8 years) to examine the association of changes in the amplitude of modality-specific alpha-range rhythms in the electroencephalogram (EEG) during anticipation of lateralized visual, tactile, or auditory stimuli with inter- and intraindividual variation in RT and EF. Children and adults exhibited contralateral anticipatory reductions in the mu rhythm and the visual alpha rhythm for tactile and visual anticipation, respectively, indicating modality and spatially specific attention allocation. Variability in within-subject anticipatory alpha lateralization (the difference between contralateral and ipsilateral alpha power) was related to single-trial RT. This relation was more prominent in adults than in children, and was not apparent for auditory stimuli. Multilevel models indicated that interindividual differences in anticipatory mu rhythm lateralization contributed to the significant association with variability in EF, but this was not the case for visual or auditory alpha rhythms. Exploratory microstate analyses were undertaken to cluster global field power (GFP) into a distribution-free temporal analysis examining developmental differences across samples and in relation to RT and EF. Anticipation is suggested as a developmental bridge construct connecting neuroscience, behavior, and cognition, with anticipatory EEG oscillations being discussed as quantifiable and potentially malleable indicators of stimulus prediction.  相似文献

We investigated the role of implicit and explicit associations between harm and COVID-19 vaccines using a large sample (N = 4668) of online volunteers. The participants completed a brief implicit association test and explicit measures to evaluate the extent to which they associated COVID-19 vaccines with concepts of harmfulness or helpfulness. We examined the relationship between these harmfulness/helpfulness COVID-19 vaccine associations and vaccination status, intentions, beliefs, and behavior. We found that stronger implicit and explicit associations that COVID-19 vaccines are helpful relate to vaccination status and beliefs about the COVID-19 vaccine. That is, stronger pro-helpful COVID-19 vaccine associations, both implicitly and explicitly, related to greater intentions to be vaccinated, more positive beliefs about the vaccine, and greater vaccine uptake.  相似文献
