The attention controls of 30 learning disabled and 30 normal males (8-to 11-years-old) were tested by a vigilance task in which vigilance was defined as ability to detect infrequently occurring signals over a prolonged time period when signals were embedded in a background of regularly occurring events. (Author/GW)

Modeling and attention-retention were examined in 20 boys (ages 9- to 14-years-old) attending a residential school for children with learning disabilities. (Author/DB)

Performances of 12 hyperactive learning disabled (LD) boys and 12 non-hyperactive LD boys were compared with two groups of 12 normal control boys (6-11 years old) on a visual search task. Ss were asked to locate a target letter appearing within an array of randomly selected letters during cued and non-cued trials. Results indicated that in the…

This study investigated the classroom attention as well as performance on simple tasks of seriously disturbed, psychotic-type, verbally communicative children under conditions of reduced auditory input (using ear protectors) and under conditions of normal auditory input (using a placebo device). No significant difference was found in either task…

Forty-two educable mentally retarded children (21 boys, 21 girls) performed an oddity learning task in one of three conditions: experimenter not present, experimenter present and providing relevant cues (RC), and experimenter present and providing irrelevant cues (IC). The experiment was designed to test J. Turnure's outerdirectedness hypothesis…

The effect of same sex and cross sex experimenters on the attentive behaviors and learning of 64 educable mentally retarded children were examined under two conditions: experimenter not present; and experimenter present and providing cues relevant to task mastery. Female Ss were found to perform significantly better with male experimenters than…

The effects of musical stimulation on activity and academic performance were studied in 36 retarded children (ages 11-19 years). (Author/DLS)

Compared were the classroom behaviors of 45 first grade children in either low, middle, or high reading ability groups. (DB)

Evaluated with 18 learning disabled boys (from 6 to 12 years of age) was the diagnostic potential of a vigilance task to evaluate the effects of medication on attention span and distractibility. (DB)

Twelve educable or trainable Ss, 14 to 22 years of age, who were institutionalized residents of a state school for the retarded, were examined in a simple vigilance test to determine effects of knowledge-of-results (KR) contingent upon correct responses. Each S in the KR group was instructed to press a switch upon seeing a light signal and to…

Eighteen hyperkinetic boys (ages 5-12) who had a history of successful drug treatment with methylphenidate were compared with a similar group of normal controls on a series of objective measures of activity and attentional problems. (Author/DLS)
