“…Although the percentage of boys selected is similar to those expected from regular schools, the number of hyperactive girls is somewhat higher than the range reported for girls (i.e., 3.2% to 7.5%, Miller, Palkes, & Stewart, 1973;Trites, Dugas, Lynch, & Ferguson, 1979;Zentall & Barack, 1979).…”

Added stimulation, both biochemical and environmental, has been used to improve the sustained attention but less frequently the search-attention performance of hyperactive children. In the present study a search task was used that differed from sustained-attention tasks only in an additional requirement for visual scanning. The performance of hyperactive and control children on a noncolored version of this task was compared with a version to which color stimulation had been presented that reduced the area to be scanned or that required a wide area to be scanned in a mixed design counterbalanced for stimulation order and level of search. Findings were that hyperactive children omitted more signals than controls on most of the noncolored search task. In the color condition, only during the last third of performance did the hyperactive children crossover with a greater increase in errors than controls. This increase, however, was attributed to the narrow-focus search condition that reduced overall visual access to task and color stimuli, effectively making that color condition less stimulating. Conclusions were that performance on search-attentional tasks, like sustained attentional performance, is normalized for hyperactive children by added color, especially during early task performance; but that the performance gains produced by color wear off more rapidly for hyperactive children, especially when a narrow focus of attention is required.

The effects of head injury in children on neuropsychological and behavioural functioning

et al. 1991

In a prospective study 76 children were divided into three groups on the basis of severity of head injury as defined by the Glasgow Coma Scale and duration of increased intracranial pressure. The children were administered a neuropsychological test battery and behavioural ratings were made by parents and teachers at three intervals: time of hospital discharge and 3 and 9 months post-initial testing. There were cognitive deficits related to severity of injury with the greatest difference in abilities observed between the severe and the other two groups. The greatest differences in skills were on the Performance IQ and timed tests of visual-motor speed and co-ordination. The greatest improvement in skills occurred in the first 3 months post-injury. Several children in coma for up to 4 weeks were able to obtain normal IQ scores. In the mild and moderate injury groups very few had behavioural change while in the severe group approximately 90% had one learning or adjustment difficulty and 40% had three or more problems.

“…Attention deficit disorder with hyperactivity (ADD-H) is among the most frequent and debilitating of childhood disorders (Barkley, 1981; Trites, Dugas, Lynch, I& Ferguson, 1979). Two of the most frequently used methods of treatment for children with attention deficit disorders are behavioral parent training (e.g., Barkley, 1981;Forehand, 1977;Patterson, 1974) and instruction in self-control techniques and problem solving (e.g., Kendall & Braswell, 1985;Meichenbaum, 1977).…”
