Age and sex-related differences in automaticity for mental addition

Research output: Contribution to journalArticlepeer-review


With age, children process information more rapidly, thus increasing access to and retrieval of information from memory. This speed of information processing is often explained in terms of automaticity. The present study explores this suggestion with respect to primary schoolchildren; 173 pupils aged between 7 and 11 years were tested using a chronometric paradigm. Analysis indicated a highly significant maturational trend towards greater automaticity across all age-groups. However, the results failed to provide evidence for sex differences in automaticity, nor was there evidence of an interaction between age and sex.
