Forsberg, Alicia; Guitard, Dominic; Adams, Eryn J.; Pattanakul, Duangporn; Cowan, Nelson – Developmental Science, 2022
We explored the causal role of individual and age-related differences in working memory (WM) capacity in long-term memory (LTM) retrieval. Our sample of 160 participants included 120 children (6-13-years old) and 40 young adults (18-24 years). Participants performed a WM task with images of unique everyday items, presented at varying set sizes.…

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.…

Cowan, Nelson; AuBuchon, Angela M.; Gilchrist, Amanda L.; Blume, Christopher L.; Boone, Alexander P.; Saults, J. Scott – Developmental Psychology, 2021
Younger children have more difficulty in sharing attention between two concurrent tasks than do older participants, but in addition to this developmental change, we documented changes in the nature of attention sharing. We studied children 6-8 and 10-14 years old and college students (in all, 104 women and 76 men; 3% Hispanic, 3% Black or African…

Forsberg, Alicia; Blume, Christopher L.; Cowan, Nelson – Developmental Psychology, 2021
Growth in working memory capacity, the number of items kept active in mind, is thought to be an important aspect of childhood cognitive development. Here, we focused on participants' awareness of the contents of their working memory, or "meta-working memory," which seems important because people can put cognitive abilities to best use…

Erikson, Jessie A.; Alt, Mary; Gray, Shelley; Green, Samuel; Hogan, Tiffany P.; Cowan, Nelson – International Journal of Bilingual Education and Bilingualism, 2021
This study examined accuracy on syllable-final (coda) consonants in newly-learned English-like nonwords to determine whether school-aged bilingual children may be more vulnerable to making errors on English-only codas than their monolingual, English-speaking peers, even at a stage in development when phonological accuracy in productions of…
