Human figure representation by blind children.

The present study examined the extent to which visual experience contributes to children's ability to represent the human figure. Nine congenitally blind children aged 7:11 to 13:7 and nine sighted children aged 7:9 to 13:6 modeled the human figure with plasticene. The controls performed more accurately than the blind children with respect to presence and placement of body parts and significantly (p less than .01) surpassed the latter with respect to proportion of body parts, even when blindfolded. Congenitally blind children did internalize a representation of the human body, but compared to that of sighted children, it was impoverished and systematically distorted. This finding suggests that tactile-kinesthetic information cannot fully compensate for visual experience in the formation of an internalized representation of the human body.

Anticipatory guidance for classroom conduct and learning problems.

Many children have learning and conduct problems due to developmental delays that are long lasting and cannot at present be cured. Within the natural history of these disorders a series of critical junctures normally arises. Informed anticipatory guidance by the physician at those times can forestall serious negative secondary effects on the child's personality development and on the family dynamics.

Effects of methylphenidate (Ritalin) on selective attention in hyperactive children.

This study investigated the effect of methylphenidate (Ritalin) on the selective attention of hyperactive children designated as favorable or adverse responders to stimulant medication. Using a type II incidental learning paradigm, it was found that children in the drug condition recalled more central and less incidental stimuli than those children in the placebo condition. While no differential effects on recall were found for responder type, methylphenidate did affect the spontaneous overt labeling of central stimuli by the favorable responder group. Results were interpreted in terms of the role of methylphenidate in narrowing the focus of attention. Implications for the classification of hyperactive children as favorable and adverse responders were also discussed.

Differences in reaction times and average evoked potentials as a function of direct and indirect neural pathways.

Average evoked potentials and manula response latencies were collected during a simple detection task in which brief visual stimuli were presented to the left and right visual fields. Latencies generated by the ipsilateral stimulus-hand combinations were shorter than contralateral combinations only under certain conditions, impugning the hypothesis that the reaction time difference reflects interhemispheric transfer time. Certain evoked potential components recorded contralateral to the stimulus occurred earlier than their ipsilateral counterparts, but whether this difference can be interpreted as representing interhemispheric transfer time is also questioned.
