Resumo
The study of attentional deficit in hyperactive children has been approached from traditional attentional theory. Theories on processing capacity limits are studied here by means of a visual and auditory dual task paradigm. The level of difficulty of the secondary task is manipulated and its effect on hyperactive (=28) and control (n=28) groups of children from grades 2-3 and 4-6 is studied. The results show that when the difficulty of the secondary task is increased hyperactive children from grades 4-6 perform worse than controls, while the opposite occurs with subjects from grades 2-3. Hyperactives show greater instability and weakness in the allocation of resources and/or in their processing capacity limits
