Original Article


The present study took advantage of data collected on more than 2100 Italian adult and elderly individuals during the standardization of the WAIS-IV to examine the relationship between working memory (WM) components and intelligence, and how age affects this relationship. Administering the WAIS-IV enabled us to obtain five different measures for assessing different aspects of WM, and a measure of General Ability (GA) strongly loading on the g-factor. The main results were as follows: (1) age-related impairments in WM are substantial, and they are partly similar and partly different for the various WM measures; (2) the relationship between the WM measures and the General Ability Index (GAI) varies, becoming stronger when the active control required by the WM task is higher; (3) comparing the WM–GAI relationships between different age groups reveals some similar patterns, as well as some specific effects that depend on the WM task considered.
