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.…

Vergauwe, Evie; Cowan, Nelson – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2015
We compared two contrasting hypotheses of how multifeatured objects are stored in visual working memory (vWM); as integrated objects or as independent features. A new procedure was devised to examine vWM representations of several concurrently held objects and their features and our main measure was reaction time (RT), allowing an examination of…

Ricker, Timothy J.; Spiegel, Lauren R.; Cowan, Nelson – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2014
There is no consensus as to why forgetting occurs in short-term memory tasks. In past work, we have shown that forgetting occurs with the passage of time, but there are 2 classes of theories that can explain this effect. In the present work, we investigate the reason for time-based forgetting by contrasting the predictions of temporal…
