The effects of frontal lobe functioning and age on veridical and false recall.
Older adults' heightened susceptibility to false memories has been linked to compromised frontal lobe functioning as estimated by Glisky and colleagues' (Glisky, Polster, & Routhieaux, 1995) neuropsychological battery (e.g., Butler, McDaniel, Domburg, Price, & Roediger, 2004). This conclusion, however, rests on the untested assumption that young adults have uniformly high frontal functioning. We tested this assumption, and we correlated younger and older adults' frontal scores with veridical and false recall probabilities with prose materials. Substantial variability in scores on the Glisky battery occurred for younger (and older) adults. However, frontal scores and age were independent contributors to recall probabilities. Frontal functioning is not the sole cause of older adults' heightened susceptibility to false memories.
