Title: The concurrent validity of the N-back task as a working memory
measure.

Abstract
The N-back task is used extensively in literature as a working memory
(WM) paradigm and it is increasingly used as a measure of individual
differences. However, not much is known about the psychometric
properties of this task and the current study aims to shed more light
on this issue. We first review the current literature on the
psychometric properties of the N-back task. With three experiments
using task variants with different stimuli and load levels, we then
investigate the nature of the N-back task by investigating its
relationship to WM, and its role as an inter-individual difference
measure. Consistent with previous literature, our data suggest that
the N-back task is not a useful measure of individual differences in
WM, partly because of its insufficient reliability. Nevertheless, the
task seems to be useful for experimental research in WM and also well
predicts inter-individual differences in other higher cognitive
functions, such as fluid intelligence, especially when used at higher
levels of load.

Comment singled out =3D  "predicts inter-individual differences in other
higher cognitive functions, such as fluid intelligence, especially
when used at higher levels of load."
