Swanson, H. Lee – Developmental Psychology, 2017
This study investigates whether age-related changes in the structure of 5 complex working memory (WM) tasks (a) reflect a general or domain specific system, (b) follows a similar trajectory across different age spans, and (c) contribute domain general or domain specific resources to achievement measures. The study parsed the sample (N = 2,471)…

Petersen, Anders; Andersen, Tobias S. – Journal of Experimental Psychology: Human Perception and Performance, 2012
The psychometric function of single-letter identification is typically described as a function of stimulus intensity. However, the effect of stimulus exposure duration on letter identification remains poorly described. This is surprising because the effect of exposure duration has played a central role in modeling performance in whole and partial…

Mammarella, Irene C.; Pazzaglia, Francesca; Cornoldi, Cesare – British Journal of Developmental Psychology, 2008
There are a large number of studies demonstrating that visuospatial working memory (VSWM) involves different subcomponents, but there is no agreement on the identity of these dimensions. The present study attempts to combine different theoretical accounts by measuring VSWM. A battery composed of 13 tests was used to assess working memory and, in…

Yuan, Kun; Steedle, Jeffrey; Shavelson, Richard; Alonzo, Alicia; Oppezzo, Marily – Educational Research Review, 2006
A review of the history of working memory (WM) studies finds that the concept of WM evolved from short-term memory to a multi-component system. Comparison between contemporary WM models reveals: (1) consensus that the content of WM includes not only task-relevant information, but also task-irrelevant information; (2) consensus that WM consists of…
