Any mature field of research in psychology—such as short-term/working memory—is
characterized by a wealth of empirical findings. It is currently unrealistic to expect a theory to …

The most replicated result in the field of intelligence is the positive manifold, which refers to
an all-positive pattern of correlations among diverse cognitive tests. The positive manifold is …

Sequential sampling models assume that people make speeded decisions by gradually
accumulating noisy information until a threshold of evidence is reached. In cognitive …

Several theories have been put forth to explain the relation between working memory (WM)
and gF. Unfortunately, no single factor has been shown to fully account for the relation …

Working memory, including central executive functions (inhibition, shifting and updating) are
factors thought to play a central role in mathematical skill development. However, results …

We review the evidence for the 3 principal theoretical contenders that vie to explain why and
how working memory (WM) capacity is limited. We examine the possibility that capacity …

A latent variable study examined whether different classes of working-memory tasks
measure the same general construct of working-memory capacity (WMC). Data from 270 …

Working memory (WM) span tasks—and in particular, counting span, operation span, and
reading span tasks—are widely used measures of WM capacity. Despite their popularity …

The question whether being bilingual yields cognitive benefits is highly controversial with
prior studies providing inconsistent results. Failures to replicate the bilingual advantage …
