Several recent studies have reported that cognitive training in adults does not lead to generalized performance improvements [1Owen A.M. Hampshire A. Grahn J.A. Stenton R. Dajani S. Burns A.S.

This is consistent with convergent evidence [5Stiles J. Reilly J. Paul B. Moses P. Cognitive development following early brain injury: Evidence for neural adaptation.Trends Cogn. Sci. (Regul.

We used gaze-contingent paradigms to train 11-month-old infants on a battery of attentional control tasks. Relative to an active control group, and following only a relatively short training period, posttraining assessments revealed improvements in cognitive control and sustained attention, reduced saccadic reaction times, and reduced latencies to disengage visual attention. Trend changes were also observed in spontaneous looking behavior during free play, but no change was found in working memory. The amount of training correlated with the degree of improvement on some measures. These findings are to our knowledge the first demonstration of distal transfer following attentional control training in infancy. Given the longitudinal relationships identified between early attentional control and learning in academic settings [9Razza R.A. Martin A. Brooks-Gunn J.
