Distraction and body-focused hand movements.
The hypothesis that apparently irrelevant self- or object-manipulatory hand movements may act as a means of coping with distraction was tested by experimentally manipulating the amount and type of distraction experienced by 10-year-old children while they engaged in the Stroop colour-confusion and colour-naming tasks. If the hypothesis was correct, then increases in distraction were expected to be associated with increases in the frequency of these body-focused movements. The external distractions consisted of either the occurrence of a light signalling the need to perform a reaction time task or listening to distracting sounds through headphones. None of the hand movements increased in frequency with increases in secondary distraction, whether the secondary distractor was visual or auditory.
