Individual Differences and Age-Related Changes in Time-Sharing Ability of Aviators

Abstract

Performance in single task and dual task configurations was examined across four different age groups to determine the presence of an attention deficit hypothesis with increasing chronological age. Although a general slowing of performance could be shown no interaction between age and dual task loadings could be observed which is interpreted as negative evidence for the attention deficit hypothesis. A separate analysis revealed individual differences in time-sharing ability within age groups to be a significant factor in dual task performance.
