Motor Effects

Perceptual-motor effects of imipramine and methylphenidate were evaluated in a double-blind study of 47 hyperactive children. No effects were found for imipramine, although methylphenidate improved performance on several tests. Improvement due to methylphenidate was not related to baseline scores. A discriminant function was computed to compare baseline perceptual-motor scores of the hyperactive and 41 normal children. Only half of the hyperactive children were clearly discriminated from normal children by the discriminant function. The digit-span test, which was not sensitive to methylphenidate, effectively discriminated hyperactive from normal children.

Performance Under Pressure

In two experiments, we examined whether training with anxiety can prevent choking in experts performing perceptual–motor tasks. In Experiment 1, 17 expert basketball players practised free throws over a 5-week period with or without induced anxiety. Only after training with anxiety did performance no longer deteriorate during the anxiety posttest. In Experiment 2, 17 expert dart players practised dart throwing from a position high or low on a climbing wall, thus with or without anxiety. Again, only after training with anxiety was performance maintained during the anxiety posttest, despite higher levels of anxiety, heart rate, and perceived effort. It is concluded that practising under anxiety can prevent choking in expert perceptual–motor performance, as one acclimatizes to the specific processes accompanying anxiety.
