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.

Abstract

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.
