Measuring Cognitive Ability

Abstract

The assessment of cognitive abilities is critical in large-scale survey studies that aim at elucidating the longitudinal interplay between the individual’s cognitive potential and socio-economic variables. The format of such studies calls for assessment methods that not only can be efficiently administered, but also show a high level of (psychometric) measurement quality. In consideration of recent theoretical and empirical advances in intelligence research, we recommend the implementation of tests drawing on working memory in large-scale survey studies. Working memory is a limited-capacity system for the temporary storage and processing of information that is currently considered to be the key cognitive system underlying intellectual abilities. Examples of four types of working memory tests are described and critically evaluated with regard to their psychometric quality and the need for further evaluation.
