Abstract
Orienting of attention was investigated in 6-, 8-, and 10-year-olds and in young adults, in a spatial cueing experiment comparing nonpredictive, predictive, and counterpredictive cues (in different blocks). A larger positive orienting effect (advantage of valid over invalid cues) in the predictive than in the nonpredictive condition occurred in all groups, showing efficient endogenous orienting of attention. However, this effect was larger in 6-year-olds, as if the ability to distribute attention between the different locations (and not only to orient to the most probable location) developed between 6 and 8 years. Moreover, only 10-year-olds and adults showed a significant negative orienting effect (advantage of invalid cues) in the counterpredictive condition, indicating inhibition of attentional capture by goal-irrelevant stimuli. Therefore, our results indicate a large change in the modulation of endogenous orienting between 6 and 10 years.

Notes
1Note that some exogenous component of attention may also be included in the cueing effect when using central cues like arrows (CitationRistic & Kingstone, 2006).
2Only one study in children used a minority of valid trials (33% with 67% invalid trials; CitationBrodeur & Boden, 2000). However, in this study, the cues cannot be considered to be truly counterpredictive, because there were eight target locations overall, and thus seven possible target locations in invalid trials. In fact, Brodeur and Boden considered their study was about the spatial uncertainty effect.
