Attentional habituation and mental retardation. A theoretical interpretation of MA and IQ differences in problem solving.

A theoretical proposal is offered concerning individual differences in cognitive processes. The focus is on mental retardation and the comparative problem-solving performance of ‘normal’ and ‘retarded’ children. On the basis of Jeffrey’s analysis of attention and cognitive development, it is proposed that IQ and MA differences in problem-solving behavior reflect differences in (a) speed of OR habituation and (b) ability to sufficiently inhibit responding.
