Bottom Line: Gender differences were also observed, with girls outperforming boys although taking more time to respond.The theoretical implications of these results are discussed.Normative data stratified by age and gender for the three WM load levels are provided.

ABSTRACT
The n-back task is a frequently used measure of working memory (WM) in cognitive neuroscience research contexts, and it has become widely adopted in other areas over the last decade. This study aimed to obtain normative data for the n-back task from a large sample of children and adolescents. To this end, a computerized verbal n-back task with three levels of WM load (1-back, 2-back, and 3-back) was administered to 3722 Spanish school children aged 7-13 years. Results showed an overall age-related increase in performance for the different levels of difficulty. This trend was less pronounced at 1-back than at 2-back when hits were considered. Gender differences were also observed, with girls outperforming boys although taking more time to respond. The theoretical implications of these results are discussed. Normative data stratified by age and gender for the three WM load levels are provided.

Mentions: There was an increase in the percentage of hits in relation to age, although the patterns observed for each n-back load were different (see Figure 1). This was confirmed by the crucial interaction between the linear trend for age and load. A trend analysis for each n-back load indicated a relatively small but significant linear increase in performance with age at the 1-back level and a more pronounced linear increase with age at 2-back.
