This study investigated the common practice in infant research of eliminating from reported data large numbers of subjects who prove uncooperative (sleepy, fatigued, fussy) during the experiment. It was suggested that these excluded infants constitute a special class of subjects and that the inclusion of their data would greatly alter the research…

The span of apprehension (a measure of the amount of information processed simultaneously from a brief visual display) was studied in two experiments involving 40 normal and learning disabled boys (ages 6-11 years). (Author/DLS)

Goals of a learning center for the severely handicapped should include individualized instruction (both academic and nonacademic); student independence; and increased self-control, attention span, and concentration. An aide should supervise the center, while the teacher provides individualized instruction. (JC)

The spans of apprehension (the amount of information processed simultaneously from a brief visual display) of 19 hyperactive and 19 normal boys (6-10 years old) were compared with a forced-choice letter-recognition task developed by W. Estes. (Author/CL)

Three groups of three boys (6-12 years old) referred to a hospital study unit for evaluation of hyperactive behavior were tested on a classification task involving selective attention while on either dextroamphetamine or placebo. (Author/CL)

Interviewed about their child's infancy and early childhood were parents of 327 elementary school children classified as low achieving, poorly adjusted, hyperactive, or control Ss. (CL)

The study of use of the drug fenfluramine with four autistic children (7-20 years old) indicated no significant side effects, a reduction in some deviant behaviors, and an improvement in activity level/attention span. (Author/DB)

The sustained attention of 23 young adults with mild mental retardation and nonretarded subjects was assessed. Findings suggested that the sustained attention of the retarded differs from that of the nonretarded on those vigilance tasks that place demands on memory abilities. (Author/DB)

Examined stability of activity and attention in 48 boys, originally evaluated as outpatients in a child psychiatry clinic. Measures of gross and fine motor activity, sustained attention, and self-vocalization showed significant stability over the two years for both free play and restricted academic settings. (Author/BL)

The study investigated the efficacy of a package of cognitive self-control procedures for ameliorating the attentional deficits of 12-year-old learning disabled children. Performance on measures of reading, attention, an inhibitory control was improved as a function of the cognitive self-instructional training. The improvement continued to sustain…

The authors comment on an article by C. Conners et al which reports the findings of a study to examine the relationship between food additives and hyperkinesis in children (6-12 years old). (SBH)
