Smooth pursuit eye movements in normal and dyslexic children 总被引:1,自引:0,他引:1
This paper describes a detailed study of horizontal eye movements associated with visual tracking of a smoothly moving target. Essentially all children, even at target velocities as low as 5 degrees/sec., show some saccadic eye movements superimposed on smooth tracking movements. Detailed analysis of pursuit eye-movements from a group of 26 poor readers and 34 normal controls (8 to 13 yr.) showed that about 25% of poor readers have an abnormally raised saccadic component in smooth pursuit. This suggests that studies of eye movements during tracking of smoothly moving targets at low velocity, combined with a quantitative approach to data analysis, may be useful for early detection of a significant proportion of poor-reading children. 相似文献

In a study examining children's social competence in elementary school settings, the authors had the opportunity to compare children who received parental permission to participate to children who did not receive permission. Results indicated that children who were not involved in the study were more likely to be viewed by teachers as having unsatisfactory relationships with peers than children who were in the study. The present results suggest that investigators begin reporting the number of children who do not participate in a given study and begin examining whether minors who receive parental permission differ on important dimensions from minors who do not receive such permission. Ethical considerations of the present study are discussed. 相似文献

Hyperactive boys on methlyphenidate (Ritalin), hyperactive boys on placebo, and comparison boys were observed in quasi-naturalistic classroom settings. Ambient stimulation (quiet versus noisy conditions) and source of regulation (self-paced versus other-paced activities) were varied in a 2 × 2 design. Compared to their peers, hyperactive boys on placebo showed lower rates of task attention and higher rates of gross motor movement, regular and negative verbalization, noise-making, physical contact, social initiation, disruption, and acts that were perceived as energetic, inappropriate, or unexpected. Self-paced activities resulted in increased rates of verbalization, social initiation, and high-energy episodes. High ambient noise levels reduced task attention and increased the rates of many other behaviors including verbalization, physical contact, gross motor movement, and high-energy acts. Medication-by-situation interactions emerged for both classroom dimensions, with hyperactive boys on placebo being readily distinguishable from their peers under some classroom conditions and indistinguishable under other conditions. Moderate relationships were found between teacher ratings and many individual behavior categories. Discussion focused on (a) the merits and limitations of a social ecological research perspective, and (b) the implications of these findings for the design of intervention strategies. 相似文献

This paper describes the neurological, language, and speech status of seven brain-damaged patients with symptoms of cortical stuttering. We compare data from our seven patients to data presented on other brain-damaged stutterers, review theories of cortical stuttering's etiology, advance alternative hypotheses about mechanisms underlying such dy sfluencies, and compare cortical stuttering to stuttering in childhood. 相似文献

The efficacy of a treatment intervention for head pain is typically evaluated by self-reported data. Self-monitoring schedules used to collect these data vary extensively across studies. The present article reviews conceptual and methodological problems with these self-report inventories. In addition, the most promising procedure was implemented in a study designed to measure the reliability of self-reported headache pain levels. One-hundred twenty-four college students self-monitored headache pain over an 8-week period. Three objective procedures were used to detect inaccurate recording. Subjects were also asked, in a post-experimental questionnaire, to subjectively rate the degree to which they complied with the experimenters' instructions regarding the self-monitoring procedures. Forty percent of the subjects were found to be noncompliant based on the detection techniques. However, responses to the postexperimental questionnaire indicated this to be a conservative estimation of noncompliance. There was no consistent difference between the postexperimental questionnaire for the subjects detected and those not detected. Results are discussed with relation to the need for researchers to adopt a standard methodology for (1) measuring self-reported headache pain and (2) reporting reliability data.Portions of these data were presented at the meeting of the Association for Advancement of Behavior Therapy, Chicago, November 1978. 相似文献

The purpose of this paper is to document the often discussed (e.g., Goldman, 1973) and recently initiated expansion of women's role in the U.S. Army and to present evidence regarding one aspect of soldiers' probable reaction to this expansion — viz., the extent to which soldiers believe certain military jobs are appropriate for women and, in particular, the extent to which these beliefs are related to respondent sex, rank, and expectation of leaving the Army before retirement. 相似文献

This investigation assessed the effects of presenting non-target stimuli in the antecedent and consequent events on the future learning of responses to those stimuli. A 4-s constant time delay procedure was implemented to teach students with mild to moderate disabilities to read sight words. Future target stimuli (i.e., stimuli that were presented during instructional sessions of initial target stimuli, but were not directly instructed or targeted) were presented in one of two conditions; (a) in the antecedent event, or (b) in the consequent event portion of each instructional trial. Future target stimuli consisted of sight words that were unrelated to the target stimuli. An adapted alternating treatments design was used to assess and compare the two instructional conditions. Also, after students achieved criterion for reading target sight words, constant time delay was implemented to teach the future target stimuli. The number of sessions and the number and percentage of errors through criterion for teaching target and future target stimuli were assessed to measure the efficiency of the two conditions. All students reached criterion on the target stimuli and then acquired the future target stimuli when taught. Students required fewer sessions to achieve criterion on future target stimuli compared to initial target stimuli. There were minimal differences between the two conditions (i.e., antecedent versus consequent). 相似文献

Previous studies on skill acquisition have taught targets in stimulus sets composed of different numbers of stimuli. Although the rationale for selection of a stimulus set size is not clear, the number of target stimuli trained within a set is a treatment decision for which there is limited empirical support. The current investigation compared the efficiency of tact training in 4 stimulus set sizes, each of which included 12 stimuli grouped into (a) 4 sets of 3 stimuli, (b) 3 sets of 4 stimuli, (c) 2 sets of 6 stimuli, and (d) 1 set of 12 stimuli. Results of all 4 participants with autism spectrum disorder show tact training with larger (i.e., 6 and 12) stimulus set sizes was more efficient than training with smaller (i.e., 3 and 4) stimulus set sizes. 相似文献

Visual analysis is integral to the analysis of single-case experimental design (SCED) data. Previous studies have shown that many factors may influence the interrater agreement (IRA) of visual analysis. One factor that has received little direct attention is the impact of contextual information. In the current study, authors of recently published SCED studies were asked to make judgments regarding functional relations based on published datasets that met criteria for design quality. Respondents were randomly assigned to view graphs with or without contextual information and the degree of interrater agreement was compared. Results revealed that contextual information had no impact on IRA for decisions of a functional relation. IRA was high across both groups for 6 of the 7 datasets examined. Implications and recommendations based on these results are discussed. 相似文献
