Interaction of Blood Pressure and Adult Age in Memory Search and Visual Search Performance

Journal Article

According to one model of the interaction between blood pressure and adult age, chronically elevated blood pressure accelerates age-related decline in fluid intelligence. To test this model, 48 unmedicated individuals with high blood pressure (HBP) and 48 individuals with normal blood pressure (NBP), comprising three categories of adult age (20-39, 40-59, and 60-79 years), performed memory search and visual search tasks. In contrast to the prediction, performance slowing related to HBP was evident for middle-aged adults, but not for the older adults, perhaps as a result of survival and selective attrition effects. There were specific age-related changes associated with memory search and visual search, in addition to generalized slowing, whereas the HBP-related changes were not task-specific.
