[Developmental continuity of working memory from infancy to preschool age]

The objective of the paper was to study the developmental continuity of working memory function from infancy to preschool age. At the age of 10 to 11 months 44 participants completed delayed response task (A-not-B) that measures working memory function. Between 5 and 7 years of age the same participants performed three tasks assessing working memory for temporal order in auditory and visual modalities and a control task measuring short-term visuospatial memory. The dependence of temporal-order memory at preschool age on individual level of infant working memory was found for all methods of measurement despite the differences in way of presentation and reproducing of the stimuli order. Results indicate direct continuity in the development of working memory function from infancy to preschool age.
