Construct Validity

There is some question about the construct validity of n-back task. While the task has strong face validity[1] and is now in widespread use as a measure of working memory in clinical and experimental settings, there are few studies which explore the convergent validity of the n-back task with other measures of working memory [1]. Those studies have largely revealed weak or modest correlations between individuals' performance on the n-back task and performance on other standard, accepted assessments of working memory. [1][2]

There are two main hypotheses for this weak correlation between the n-back task and other working memory assessments. One proposal is that the n-back task assesses different "sub-components" of working memory than do other assessments. A more critical explanation is that rather than primarily assessing working memory, performance on the n-back task depends on "familiarity- and recognition-based discrimination processes," whereas valid assessments of working memory demand "active recall."[2] Whatever the cause of the performance differences between the n-back and other assessments of working memory, some researchers stress the need for its further exploration.[1]

Furthermore, performance on the n-back task seems to be more closely correlated with performance on measures of fluid intelligence than it is to performance on other measures of working memory (which is also correlated with performance on measures of fluid intelligence). [2] In the same vein, training on the n-back task appears to improve performance on subsequent fluid intelligence assessments, especially when the training is at a higher n-value. [2]
