This study examined the ability of 7 learning disabled children to detect and integrate visual features in a complex display. While the learning disabled children performed more poorly over-all than 6 control children, differences between the two groups were most pronounced when subjects were required to conjoin or integrate visual features to make a decision about the presence of a target item. This finding is discussed with reference to automatic and attention-demanding components of visual perception. 相似文献

We conducted two experiments in which moderately mentally retarded persons were trained first to label and then to enter characters into a computer, calculator, or checkbook (label-then-do) within a multiple baseline design. In Experiment 1, 5 young adults were trained to enter statistical programs into computers in an office setting. Following training, all subjects' use of verbal labels and key-entry skills generalized across tasks (programs) and settings (offices and computer terminals). In Experiment 2, 3 junior high school students were trained with self-labeling procedures to complete a key-entry task and to balance a checkbook. The performance of all students generalized across tasks and settings, and the use of labels generalized for 2 of the students. Results are discussed relative to mediated generalization and to establishing verbal control over behavior. 相似文献

Behavioral assessment procedures were used to determine the maintaining conditions of self-injury exhibited by 2 children with severe multiple handicaps. For both children, negative reinforcement (escape from grooming activities) was determined to be the maintaining reinforcer for self-injury (hand/arm biting) within an alternating treatments design. The treatment packages involved the use of negative reinforcement (brief escape from grooming activities) contingent upon a behavior that was incompatible with self-injury (reaching and pressing a microswitch that activated a prerecorded message of “stop”). Treatment was evaluated with a reversal design for 1 child and with a multiple baseline across grooming activities for the 2nd child. The treatment led to a marked decrease in self-injury for both children. At follow-up, high rates of self-injury were reported for the 1st child, but low rates of self-injury and an increase in task-related appropriate behavior were observed for the 2nd child. 相似文献

Calls to a community help line for children were analyzed for developmental and gender trends in support-seeking during middle childhood. Results indicated that between the ages of 10 and 11 the nature of help-seeking by callers changed, with a shift toward more informational support-seeking and concern regarding interpersonal problems. This shift was particularly dramatic for girls. Gender differences in the type of support sought (informational vs. instrumental) were slight. Parallels with other studies of stress and coping in children are drawn. 相似文献

Three experiments were conducted to determine if a representation of the movement environment is functional in the organization and control of limb movements, when direct visual contact with the environment is prevented. In Experiment 1, a visual rearrangement procedure was employed to show that a representation of the environment that provides inaccurate information about the spatial location of a target can disrupt manual target aiming. In Experiment 2, we demonstrated that spatial information about the position of a target can be destroyed by a visual pattern mask, supporting our claim that the representation is visual. A target-cuing procedure was used in Experiment 3 to show that representation of target position can be useful for premovement organization in a target-aiming task. Together our findings suggest that a short-lived visual representation of the movement environment may serve a useful role in the organization and control of limb movements. 相似文献

DSM-IV will benefit from the extensive research and interest in diagnosis generated in large part by DSM-III. The development of DSM-IV is proceeding through three stages of empirical documentation, including literature reviews, analysis of unpublished data sets, and field trials. This paper discusses the rationale, process, and limitations of the literature reviews. The purpose of the literature reviews is to provide and to document a comprehensive review of the clinical and empirical literature to facilitate objective and empirically based decisions. The review process is guided by the explicit and systematic methods developed within meta-analysis. Limitations of the reviews are also discussed.The opinions expressed in this paper are those of the authors and do not necessarily represent the position of the American Psychiatric Association and its Task Force on DSM-IV. 相似文献
