Due to an error at the Publishers' office Figs 1 and 2 in the article ‘Putative biomarker of working memory systems development during childhood and adolescence' by Hannah A.D. Keage, Christopher R. Clark, Daniel F. Hermens, Leanne M. Williams, Michael R. Kohn, Simon Clarke, Christopher Lamb, David Crewther and Evian Gordon [1], which appeared on pp. 197–201 of Neuroreport Volume 19 issue 2 were published incorrectly.

Fig. 1
Fig. 1:
(a) Mean probabilities of cluster membership relative to 1-year age bands; (b) means (±standard error of mean) for all performance measures for each cluster; and (c) the canconical discriminant functions indicating each cluster centroid.
Fig. 2
Fig. 2:
(a) Grand mean event-related potential (ERP) (microvolts displayed on they-axis and milliseconds displayed on the x-axis) waveforms from frontal (FZ), central (CZ) and pariental (PZ) scalp sites relative to cluster membership, with key components identified and (b) significant change between the clusters for all ERP amplitude and latency measures, with directions of difference indicated by arrows.

The online versions have now been corrected, and appear below. We apologise for the error.
