title: Performance on the Hayling and Brixton tests in older adults: norms and correlates.
abstract: The individualized nature of the aging process underlines the need to have neuropsychological tests that are sensitive enough to distinguish normal changes associated with aging from those that are pathological. However, these measures are only useful if adequate normative data are available. Normative data are presented for two new executive functioning tasks, the Hayling and Brixton tests, which were administered as part of a neuropsychological battery to 457 typically aging older adults (53-90 years). Advancing age was associated with poorer performance on both the Hayling and Brixton tests. Results showed that fluid intelligence accounts for some but not all of the age-related variance on these tasks.
