  • Title: The development of non-spatial working memory capacity during childhood and adolescence and the role of interference control: an N-Back task study.
    Author: Schleepen TM, Jonkman LM.
    Journal: Dev Neuropsychol; 2010; 35(1):37-56. PubMed ID: 20390591.
    Abstract:
    To investigate the role of interference control on the development of working memory (WM) capacity, 6-12-year-old children and adults performed an N-Back task with differing WM-load and interference control demands. Correlation analyses between flanker interference scores and WM-load levels showed that interference control was only required in the 2-back condition. While WM maintenance (1-back task) reached adult accuracy levels at age 10-12, the ability to maintain information in WM during distraction (2-back-task) displayed protracted maturation into adolescence. This is suggested to reflect yet immature connections between prefrontal and posterior association areas, respectively involved in interference control and WM storage.
