Abstract
The issue of whether aging affects the feeling-of-knowing (FOK) function of episodic memory has been controversial. Methodological drawbacks, such as inadequate FOK measures and confounding variables of the demographical data might account for such inconsistent findings. In order to clarify this debatable issue, the author made an attempt to minimize these pitfalls in the present study. Furthermore, the literature regarding neuropsychological mechanism of FOK in Taiwanse aging has been lacking. Thus, the primary objectives of this study were to explore episodic memory FOK function in normal aging and its possible neuropsychological mechanism. Thirty-four normal older adults and thirty-five normal young controls matched for sex, education level and VIQ of the WAIS-R were participated in the study. Each participant received a series of neuropsychological test batteries and RJR paradigm. The results revealed: (1) that FOK accuracy did not vary by age, and (2) FOK judgment task performance in normal aging was significantly correlated with certain frontal neuropsychological measures, while normal young participants’ judgment performance was remarkably correlated with episodic memory function tests. On the basis of the results, it appeared that the underlying neuropsychological mechanisms for FOK judgment of episodic memory between normal aging and their normal young counterparts were different. However, since this conclusion was merely based on neuropsychological measure correlates rather than on the structural or functional neuroimaging findings, further investigation thus is merited.
