We present a theory suggesting that the ability to build category representations that reflect the nuances of category structures in the environment depends upon clustering mechanisms instantiated in an MTL-PFC-based circuit. Because function in this circuit declines with age, we predict that the ability to build category representations will be impaired in older adults. Consistent with this pr...

Age-related Declines in the Fidelity of Newly Acquired Category Representations

Supplementary Materials Methods Subjects Thirty-Seven older adults (Average age = 69.65; Range = 59-82) and 32 younger adults (Average age = 20; Range = 18-26) participated in the experiment for monetary compensation.

However, increased age is seldom associated with lower levels of real-world functioning, and the reasons for this lab-life discrepancy are not well understood. This article briefly reviews research concerned wi...
