Examined which of the attentional operations underlying exogenous orienting (disengaging, shifting, and/or engaging) improves with age in children from 6 to 14 years old. Found that disengaging attention alone distinguished between younger and older children's performance, regardless of whether attention alone or attention and associated sensory and motor systems were involved. Found that even younger children could use the predictability of a cue to enhance their performance. (JPB)
