Age, attention, expertise, and time-sharing performance

Article Abstract:

An experiment was undertaken to analyze the relationship of time-sharing task performance with aging. Two aspects of time-sharing performance were examined, namely, time-sharing efficiency and resource allocation. The experiment's participants were expert pilots and nonpilots aged 20 to 79 years old. Results showed that time-sharing efficiency diminished with increased age and that expertise reduced the adverse effects of age. Time-sharing performance through attentional resources was influenced by age, expertise and structural similarity.

Perceived problems for self and others: self-protection by social downgrading throughout adulthood

Article Abstract:

A study was conducted to assess and identify social downgrading as reflected in the difference between perceptions about the self and a given domain. Results indicate that with regard to all domains, younger, middle-aged and older adults believed other people's problem to be more serious than their own problems in these domains. Social downgrading was evident for those domains in which a given respondent experienced his or her own problems. The self-protection tendency under threat was prevalent among older adults.

The moderating influence of physical fitness on age gradients in vigilance and serial choice responding tasks

Article Abstract:

Physical fitness influences the relationship between age and signal sensitivity, and processing speed. Fitness attenuates age-related performance deficits related to vigilance, and serial choice responding tasks. A study with postal workers reveals that less fit older individuals exhibit performance decrement in signal sensitivity and processing speed, compared to older fitter individuals and younger people. Task duration influences the difference between older and younger subjects in performance.
