Separate integral responding in children demonstrating attention deficit disorderAmin, Kiran January 1987 (has links)
Integral (holistic) and separable (analytic) processing were studied in ADD-H and normal children using restricted classification tasks composed of separable dimensions and triad/tetrad combinations. In Studies One and Three classifications of ADD-H children and controls were compared on size/brightness and length/density combinations. In Study Two classifications of four age groups of normal subjects (mean ages 5-3, 7-9, 11-1 years and adults) were compared on size-brightness combinations. ADD-H children demonstrated significantly fewer separable responses than normal controls only on the tetrads. Normal subjects showed a developmental trend towards differential separable responding to size as compared to brightness. ADD-H children appear to show a lag of about two years on this developmental trend. Results suggest that ADD-H children resort more readily than normals to integral responding under increased processing load. Results are discussed in terms of the cognitive deficits of ADD-H children and current theories of perceptual differentiation.

Examination of the implementation of a job-related social skills program in high school classes for students categorized as cognitively impaired: a case study approachHarris, Carolyn DeMeyer January 1989 (has links)
A job-related social skills program for high school students with mild cognitive impairments, using a range of media materials has been implemented in several school districts in Virginia. The program, developed under the auspices of the U.S. Office of Special Education Programs, will be examined in this study for issues of implementation and adoption in public high schools. The use of traditional experimental designs in program evaluation is seriously questioned when complex issues of implementation are involved. These issues are magnified in special education settings where subject assignment, sample size, individualized instruction, and teacher choice of materials are uniquely present. Consequently, a case study approach of four classrooms following the techniques of Miles and Huberman and Yin was used to examine the implementation process.
Three major factors were used to organize data collection: teacher understanding of existing curriculum and goals and teaching style, congruence between the existing and new content and decision making related to implementation, and instructional delivery and the way program use actually looked. While all teachers appeared to like and accept the program, they did not want it to alter their existing classroom plans, teaching styles, and personal interaction approaches. Each teacher showed a unique defense of his or her existing educational style, and the new program was adapted to the ongoing classroom situation, rather than vice versa. If faced with decisions between using the new program and fulfilling existing requirements, these teachers chose to reject the program. The great variation in implementation and modification of the program across these sites supports the need for more careful descriptive site by site studies that allow for differences that cannot easily be identified in quasi-experimental designs. / Ph.

Organization of Narrative Discourse in Children and Adolescents with Acute Traumatic Brain InjuryThomas, Kathy Lee 05 1900 (has links)
Children with a recent history of TBI often demonstrate impaired memory, which can be affected by impaired attention, processing speed or impaired verbal information processing. The purpose of this study was to determine if qualitative differences exist among the narrative recall of TBI patients that is not adequately accounted for by standard scoring methods. Sixty-six TBI subjects ranging in age from 6 to 16 were given the Wide Range and Memory and Learning (WRAML) Story Memory subtest and selected subtests from the Wechsler Intelligence Scale for Children - Third Edition (WISC-III). Mean elapsed time since injury was 53 days. Recall of the story on the WRAML subtest was hand-recorded by the examiner. A supplemental scoring method accounted for differences in length, errors, and disorganization. Comparisons were made to a randomly selected control group consisting of 16 hospitalized subjects between 7 and 15 years with no history of head injury, neurological condition or event. Findings suggest the WRAML Story Memory subtest is relatively robust in providing information regarding the quality of recall, with the exception of not accounting for the addition of erroneous details. Subjects with both cortical and subcortical injuries were more likely to add superfluous details to their stories. Results also demonstrated significant differences between the TBI subjects and control group in how well the stories were recalled, primarily in the order of details recalled and in retention after a 30 minute delay. Location was not a significant predictor of narrative organization. Although using this comprehensive supplemental scoring system a regular basis has practical limitations, hand-recording the narrative takes relatively little time and does appear to provide useful additional information concerning the nature of the child's verbal memory difficulties. Furthermore, the more knowledgeable the child, parents and teacher are about these difficulties and about remediation strategies, the more likely the child will have a successful learning experience upon return to the classroom.
