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.

为了可以组织不同方向的注意力，必须对它们进行标记和评估。对一般问题的陈述可以视为一般注意方向的标签。对它的希望，因为根据完成的工作而获得的足够成功的感知概率，可以视为一种评估。可以争辩说，婴儿由于在2个不相容的普遍问题上的研究而陷入僵局，（1）提高对环境的确定性的希望（与反复刺激作用较小的唤醒系统有关），和（2 ）提高产生效果的希望（与激活系统相关，因为此处必须在停止活动之前产生某种效果）。确定性假设
