Computerized Measures of Verbal Working Memory Performance in Healthy Elderly Participants

ABSTRACT: Purpose: Computerized measures of working memory offer advantages of precision, efficiency, and examiner control and are therefore reported more frequently. However, the influence of computer stimulus parameters is still unclear, primarily because they are not uniformly used or reported in published research. Method: Twenty-four individuals with no reported neurological or serious medical conditions completed a computerized battery of 0-, 1-, and 2-back tasks presented in 2 modalities and 3 levels of interstimulus intervals (ISIs). Results: Response time (RT) lengthened and accuracy decreased in a 2-back compared to a 1-back task of working memory. Visual or auditory presentation of stimuli generally did not influence RT or accuracy. RT lengthened A Computerized Measures of Verbal Working Memory Performance in Healthy Elderly Participants
