Abstract

We examined the ability of children (mean age: 10.4 years) and adults (mean age: 20.7 years) to prepare finger keypress responses in an anticue paradigm by presenting left and right spatial cues, which specified right and left hand finger responses, respectively. Four time intervals separated cue onset from target onset: 200 ms, 600 ms, 1000 ms, and 2000 ms. Results showed that, overall, children responded slower and less accurately than did adults; nevertheless they were equally effective in using anticue information to reduce reaction time with preparation intervals of 600 ms and longer. This outcome is discussed in terms of a slow, voluntary, top-down executive process that redirects motor preparation from the ipsi-to the contralateral hand. The absence of an age effect suggests an early maturation of the underlying neural mechanisms.
