Factor analysis of three standardized tests of memory in a clinical population (pages 169-180)

Objectives. The aim of this study was to determine the factor structure of three standardized memory tests: Wechsler Memory Scale‐Revised (WMS‐R), Warrington Recognition Memory Test (WRMT), Doors and People Test (D&P). We investigated whether these different standardized tests of memory are consistent in their evaluation of memory function, and the extent to which these tests} discriminate between different memory functions (e.g. recall/recognition and verbal/non‐verbal memory).

Design. Fifty patients with selective memory impairment were tested on the WMS‐R, WRMT and D&P.

Methods. Age‐scaled scores from selective measures of these tests (WMS‐R‐verbal, WMS‐R‐visual, WMS‐R‐delay, WRMT‐words, WRMT‐faces, D&P‐people, D&P‐doors, D&P‐shapes, D&P‐names) were used as input to a factor analysis.

Results. Maximum likelihood factor analysis yielded a three‐factor solution consistent with a theoretically motivated fractionation of memory function into recall and recognition components. Recognition performance, but not recall performance, showed dissociation into visual and verbal components.

Conclusions. The WMS‐R, WRMT and D&P are highly consistent in their assessment of memory function. The results of the factor analysis are consistent with a theoretically motivated fractionation of recall and recognition memory. They are also partially consistent with a dissociation between visual and verbal memory function.
