Development of Selectivity

This chapter considers the processes that determine what is selected for attention and how changing selection reflects developmental transitions. Although what is selected depends on the developing capacity of the receptors, a number of inhibitory mechanisms also ensure that, after 2 to 3 months, attention is more strongly influenced by experience. Novelty is especially important from 3 to 9 months when the orienting/investigative system is dominant. However, selectivity also changes as a result of emotional and social development, with fear of strangers, for example, and its attentional concomitants, becoming evident around 9 months. With the development of the second, high-level system of attention, the older infant and toddler becomes increasingly sensitive to the others' line of regard and more skilled at directing the attention of others.

Keywords: visual preferences; novelty; habituation; inhibitory mechanisms; social attention
