The present study examines the hypothesis that motor responses added into rote tasks would modulate the sensation-seeking activity and impulsive errors of hyperactive (ADD-H) children. To this purpose 22 ADD-H and 25 comparison children were administered two repetitive tasks (word decoding and an auditory vigilance task) under both an active response and a passive response condition. Findings were that the impulsive errors, talking/noise-making, and activity of ADD-H children was normalized (i.e., did not differ from comparison children) only in the high stimulation active response conditions. Behavioral improvements for ADD-H children were documented in both tasks in the active condition, but performance gains were found only in the vigilance task. The findings supported predictions derived from the optimal stimulation theory that the excessive activity and attraction to novel stimuli of ADD-H children can be channeled into appropriate instrumental motor and attention responses.We thank Anne Dwyer for her help with data collection, and Phyllis Kikendall, Sylvia Kottler, Joe Boggs, and Cheryl Wieczorek for their assistance at various stages of this project. We are also most grateful to Martha Eger and to the teachers, Sally Schnieder and Denise Oliver, of West Central Joint Special Services, to Pat Welch of the Catholic Social Services, and to the teachers of St. Ann's School and St. Philip Neri School for their cooperation with this research. 相似文献

This study assessed the applicability of Cues-Pause-Point language training procedures in teaching students to obtain information from the statements of others. Two mentally retarded subjects, one of whom was echolalic, received training on one set of stimuli but not on another. During training the subjects were encouraged to remain quiet before, during, and briefly after the presentation of statements and then verbalize (i.e., answer a question) using the verbal cue(s) that had been presented in the statement. Correct responding reached 100% to the trained stimuli and both subjects' responding improved to the untrained stimuli. Posttests revealed that subjects used the trainer's statements to answer novel questions. The results suggest that Cues-Pause-Point procedures may be useful in teaching severely retarded individuals the functional use of observing and listening to others' verbal behavior. 相似文献

The cross-modal matching techniques that have produced scales of sensory magnitude for a variety of perceptual continua in adults were used to construct similar scales in children. Subjects were adults and children 4, 6, 8, and 12 years old. Their task was, first, to match the loudness of a 1000-Hz tone to various visual lengths, and, second, to match the length of a white tape to various loudnesses of the tone. Almost all subjects were able to perform the matching tasks; the average precision of older subjects (12 and Adult) was somewhat greater, but in each of the younger age groups a majority of subjects performed with a precision that equaled that of older subjects. The exponent of the power function that relates length and loudness does not change with age. The scale factor does change, in a way that suggests either that a given sound intensity seems softer, or, more probable, that a given length seems longer, to younger children. The success of cross-modal matching with subjects as young as 4 years means that it is possible to investigate not only single perceptual scales but also intermodal organization in young children. 相似文献

This study of hyperactive boys evaluated the effects of three modes of treatment in relation to an untreated group. The treatments were administered over a 3-month period and included cognitive training, stimulant drug therapy (methylphenidate), and the two treatments combined. A follow-up assessment was conducted approximately 3 months after contact between the training staff and the child had ceased. Analyses of attentional deployment and cognitive style measures, tests of academic achievement, and behavioral ratings showed that only those children in the two medication treatment conditions demonstrated improvement in attentional deployment and behavioral ratings. In the cognitive therapy condition, there were changes only on measures of attentional deployment. The data did not provide evidence indicating that the combined medication and cognitive therapy condition was any more effective than that condition involving medication alone. Discussion provides future guidelines for evaluation of the relative effectiveness of stimulant drug therapy and other psychological treatment modalities. 相似文献

This study was designed to determine if perceptual phonological analysis would reveal distinctions between patients with apraxia of speech and patients with phonemic paraphasic speech. Test findings from 10 Broca's aphasics with apraxia of speech were compared to findings from 10 paraphasic speakers (5 conduction and 5 Wernicke's aphasics). Several marked differences were revealed. Predominant locus of errors and relative difficulty of different classes of phonemic segments were significant discriminators. There was a nonsignificant trend for substituted phonemes to be further from target phonetically in the paraphasic patients. In addition, the two groups showed certain consistent differences in the types of errors they produced. Apraxic patients produced many errors of transitionalization, while sequencing errors were more typical of the patients with phonemic paraphasia. The findings are interpreted in relation to a neuropsychological model of speech. It is suggested that phonemic paraphasia represents a breakdown mainly in the retrieval of phonological word patterns, while apraxia of speech is characterized predominantly by a disturbance in encoding phonological patterns into appropriate speech movements. 相似文献

A survey method was designed to evaluate the effect of shift work on industrial workers and to develop recommendations for 7-day around-the-clock production work systems. A Work-Sleep Survey was then offered to 2,340 hourly and salaried workers at four plants. Each plant was in the rubber and plastic products industry and on 5-day around-the-clock operations using permanent shifts. Of the total workers, 90.38% responded to the survey. The results agree with the findings of a previous survey, offered to workers through their unions, using many of the same survey items. The plants were found to differ in worker demographics, habits, and preferences. This survey method is helpful as an aid for the design and evaluation of shift-work systems tailored to specific worker and plant requirements. 相似文献

Although it is generally assumed that vision is orientation invariant, that is, that shapes can be recognized regardless of viewing angle, there is little evidence that speaks directly to this issue, and what evidence there is fails to support orientation invariance. We propose an explanation for the previous results in terms of the kinds of shape primitives used by the visual system in achieving orientation invariance: Whereas contours are used at stages of vision that ore not orientation invariant, surfaces and/or volumes are used at stages of vision that are orientation invariant. The stimuli in previously reported studies were wire forms, which can represented only in terms of contour. In four experiments, testing both short-term and long-term memory for shape, we replicated the previous failures of orientation invariance using wire forms, but found relatively good or perfect orientation invariance with equivalently shaped surfaces. 相似文献
