Forsberg, Alicia; Adams, Eryn J.; Cowan, Nelson – Developmental Science, 2023
We investigated how visual working memory (WM) develops with age across the early elementary school period (6-7 years), early adolescence (11-13 years), and early adulthood (18-25 years). The work focuses on changes in two parameters: the number of objects retained at least in part, and the amount of feature-detail remembered for such objects.…

Gilchrist, Amanda L.; Cowan, Nelson; Naveh-Benjamin, Moshe – Journal of Experimental Child Psychology, 2009
Child development is accompanied by a robust increase in immediate memory. This may be due to either an increase in the number of items (chunks) that can be maintained in working memory or an increase in the size of those chunks. We tested these hypotheses by presenting younger and older children (7 and 12 years of age) and adults with different…

Cowan, Nelson – Journal of Experimental Child Psychology, 1999
Established the differential maturation of rapid-speaking durations and the durations of interword pauses in the memory-span-task responses of first, third and fifth graders. Found that a particular memory span is accompanied by different profiles of processing rates in children of different ages. (Author)

Cowan, Nelson; Nugent, Lara D.; Elliott, Emily M.; Ponomarev, Igor; Saults, J. Scott – Child Development, 1999
This study examined ability of first and fourth graders and adults to recall digits they heard while they were carrying out a visual task. Results suggested that each individual has a core memory capacity limit that can be observed in circumstances in which it cannot be supplemented by mnemonic strategies. The capacity limit increases with age…

Cowan, Nelson; And Others – Child Development, 1982
Investigates preperceptual auditory storage among eight 9-week-old infants in three experiments using a modification of an adult masking paradigm and a nonnutritive sucking discrimination procedure. Results suggest that echoic storage contributes to auditory perception in infancy and, for infants compared to adults, echoic traces have a longer…
