| Annotation | Time-sharing (performing more than one task simultaneously) is an important component of many daily activities such as driving. This study examined time-sharing efficiency and resource allocation in a group of pilots with expertise in time-sharing and a group of non-pilots (ages 20-79 years). Participants performed five dual tasks representing different degrees of structural similarity as characterised by the structure-specific resource model. Age, expertise, and structural similarity were found to affect time-sharing performance interactively through attentional resources. Age-related deficits (only prominent in the over 60s) in time-sharing were evident under conditions of intense attentional demands, and when precise control was required. Modest expertise modulation of the age effects is likely to increase with more domain-specific time-sharing. The structure-specific resource model provided a useful framework for interpreting the relationship between ageing and time-sharing performance. (RH). |
