During infancy

Early researchers studying the development of the frontal cortex thought that it was functionally silent during the first year of life. Similarly, early research suggested that infants aged one year or younger are completely passive in the allocation of their attention, and have no capacity to choose what they pay attention to and what they ignore. This is shown, for example, in the phenomenon of 'sticky fixation', whereby infants are incapable of disengaging their attention from a particularly salient

 target. Other research has suggested, however, that even very young infants do have some capacity to exercise control over their allocation of attention, albeit in a much more limited sense.

During childhood

As the frontal lobes mature, childrens' capacity to exercise attentional control increases, although attentional control abilities remain much poorer in children than they do in adults. Some children show impaired development of attentional control abilities, thought to arise from the relatively slower development of frontal areas of the brain, which sometimes results in a diagnosis of Attention Deficit Hyperactivity Disorder (ADHD).

Disrupted development of attentional control in abnormal development

Disrupted attentional control have been noted not just in the early development of conditions for which the core deficit is related to attention such as ADHD, but also in conditions such as autism

 approaches to development, particular importance has been attached to attentional control, since it is thought to be a domain-general process that may influence the subsequent acquisition of other skills in other areas.
