Developmental changes in inhibition of return from 3 to 6 months of age

The development of inhibition of return was examined in 3–6-month-olds using varied stimulus onset asynchronies. The 300 ms SOA condition revealed particularly interesting findings as it elicited facilitation in 4.5-month-olds, but inhibition in 6-month-olds. Implications for understanding the development of IOR are discussed.
