Recognition and retrieval of proper names: Age differences in the fan effect

Abstract

A spreading activation model was applied, to explain. some aspects of retrieval failure for proper names. The fact that retrieval failures occur more frequently for well-known names than for unfamiliar names, and the increased incidence of name blocking in the elderly, are both interpreted in terms of the fan effect. Fanning is created when multiple far are known about a single person and results in slower and more error-prone retrieval, but the fan effect can be counteracted if the facts form an integrated set. Three groups of subjects—young, middle-aged, and elderly—learned sets of name-attribute statements in three conditions. In the no-fan condition, each name was uniquely paired with a single attribute; in the fan condition, each name was linked with three different attributes; in the crossed-fan condition, different names shared some of the same attributes. Verification RTs and cued recall responses showed that all subjects found the crossed-fan condition most difficult, but, when name-attribute links were not crossed, young and middle-aged subjects were able to counteract the fan effect by integrating the facts into a unified representation. Elderly subjects were less able to integrate effectively and were more susceptible to the fan effect.
