Eighteen 15-week-old, normal full-term infants were presented with photographic slides of a human facial expression. The infant's heart rate, body movement, and visual attention were recorded simultaneously. The results showed that heart rate and body movement were significantly correlated during visual attention but not during inattention. Both heart rate and body movement decelerated significantly when the infants visually attended to the target stimulus. The results are discussed with reference to cardiac-somatic integration in early infancy and its implication as a possible index of attention. 相似文献

The predictions of cognitive theory of depression with regard to personality modes have not been consistently supported. One explanation is that theoretical attention has been unduly centered on maladaptive aspects of personality. The content validity of the Sociotropy-Autonomy Scale (SAS) was explored with regard to the external correlates of positively and negatively self-evaluative items. One hundred twenty-four undergraduates completed the SAS and several criterion measures. Positively and negatively toned SAS items exhibited different external correlates, with only negatively toned items being associated with symptom and negative cognition measures. Moreover, the pattern of mood correlates reported by Clark and Beck (1991) for three subscales of a revised SAS Autonomy scale corresponded to the valence of each subscale's items, as determined by content analysis. Whereas sociotropy and autonomy are conceptually defined in terms of placing a high value on certain goals or experiences, the SAS may be overbalanced by expressions of self-criticism or insecurity about these values. 相似文献

The saccadic reaction times (SRTs) in the overlap, no-overlap, and gap conditions of 2.5- to 12-month-old infants and adults were measured. In the overlap condition, the SRTs of younger infants were over 600 ms longer than those of older infants, whereas the SRTs in the gap condition of the younger infants were 300–350 ms, much faster than reported hitherto, and were shortened only by about 100 ms. The results indicate that the oculo-motor system and attention process for disengagement in the gap condition mature earlier than the attention process for disengagement in the overlap condition. 相似文献

The Student Guided Functional Assessment Interview: An Analysis of Student and Teacher Agreement 总被引:1,自引:0,他引:1

Functional assessment strategies are used to guide the treatment of problem behavior with individuals who have severe disabilities. Also, researchers have extended functional assessment applications to individuals with emotional and behavioral disabilities. One such extension is the use of students as informants in the functional assessment process. The present study assessed an interview tool designed to elicit information directly from students regarding their problem behaviors. We examined agreement between students and their teachers. Results showed high agreement on the causes and functions of problem behavior with mixed agreement on support plan recommendations. 相似文献

We conducted reinforcer assessments for 3 boys with a diagnosis of attention deficit hyperactivity disorder who alternately received either placebo or previously prescribed methylphenidate. Our purpose was to evaluate whether methylphenidate altered the relative reinforcing effectiveness of various stimuli that are often used in classroom-based behavioral treatment programs (e.g., activities, tangible items). Results showed clear differences for some stimuli between reinforcer assessments conducted when participants had received methylphenidate compared to placebo. Results suggest that methylphenidate might act as an establishing operation for some common classroom reinforcers. Implications for the development and evaluation of behavioral treatments are discussed. 相似文献

Individualized assessments of the effects of three doses of methylphenidate (MPH) were conducted for 2 students with attention deficit hyperactivity disorder within each child's classroom using behavioral, academic, and social measures. A double-blind, placebo-controlled, multielement design was used to evaluate the results. Results suggested that at least one or more dosages of MPH were associated with some degree of improvement for both children in each area of functioning as compared to placebo. However, the degree of improvement at times varied substantially across dosage and area of functioning. Results suggest that MPH dosage and area of child functioning are critical assessment parameters and that controlled clinical trials are necessary to optimize the effectiveness of treatment with MPH for the individual child. 相似文献

We examined the effects of a behavioral intervention and methylphenidate (MPH) on inappropriate behavior and sleep disturbance displayed by a 6-year-old boy who had been diagnosed with attention deficit hyperactivity disorder. Results showed that the behavioral intervention was effective in reducing inappropriate behaviors to near-zero levels regardless of the presence or absence of MPH. 相似文献

A Bayesian framework for making mastery/nonmastery decisions based on multivariate test data is described in this study. Overall, mastery is granted (or denied) if the posterior expected loss associated with such action is smaller than the one incurred by the denial (or grant) of mastery. An explicit form for the cutting contour which separates mastery and nonmastery states in the test score space is given for multivariate normal test scores and for a constant loss ratio. For multiple cutting scores in the true ability space, the test score cutting contour will resemble the boundary defined by multiple test cutting scores when the test reliabilities are reasonably close to unity. For tests with low reliabilities, decisions may very well be based simply on a suitably chosen composite score.This work was performed pursuant to Grant NIE-G-78-0087 with the National Institute of Education, Department of Health, Education, and Welfare, Huynh Huynh, Principal Investigator.
