title: Hemisphere specialization as an aid in early infancy.
abstract: In order that different directions of attention can be organized, they have to be labeled and assessed. A statement of a general problem can be regarded as a label for a general direction of attention. Hope about it, as the perceived probability of sufficient success, on the basis of work done, can be regarded as an assessment. It can be argued that a young infant meets an impasse arising from the work on 2 incompatible general problems, (1) that of raising hope of certainty about the environment (linked to the arousal system because repeated stimulation has less effect), and (2) that of raising hope of producing effects (linked to the activation system because here some effect must be produced before activity can cease). A certainty-right hypothesis, that the right hemisphere deals with the certainty problem and the left deals with the producing-effects problem, and hence keeps work on the two problems apart in early infancy while the corpus callosum is undeveloped, and that a matching specialization continues in later life, is supported.
