Memory aging as a general phenomenon: Episodic recall of older adults is a function of episodic recall of young adults.

The focus of this study was on the relationship between young and older adults' performance on tasks of deliberate recall from episodic memory. A meta-analysis on 91 relevant studies (comprising a total of 154 conditions) was conducted. It was found that 83% of the variance in older adults' recall probability was accounted for by a quadratic function using young adults' recall probabilities as predictors. No significant interaction with age of older adults was found. Interaction with task type was, however, significant, resulting in separate functions for list recall, prose recall, and paired-associate recall. Results point at the importance of the main effect of age in studies on memory aging. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
