- W184416929 abstract "A screening study was carried out in normal elderly volunteers to determine 1. their scores in measures of memory and information processing 2. how the measures correlate with sample characteristics 3. how the measures correlate with each other and with the EEG. We report here on 111 subjects, 56 women and 55 men aged 53-77 years (63.9 +/- 6.8) with average intelligence (Coloured Progressive Matrices CPM 26.7 +/- 5.1). In the C-normed measures of the word list from the Nuremberg Geriatric Inventory (NGI) our sample scored better than average (immediate recall of words C = 7.5, delayed recall of words C = 8.2; mean C = 5). The sample even attained ceiling scores in the test of recognition. The sample likewise had a better than average speed in a color-word test (CWT) of focused attention similar to the Stroop test (e.g., reading C = 7.5, color-naming C = 6.7, interference task C = 6.3) and in the ZVT trail-making test (C = 7.0). In contrast, speed-free focused attention was only average (C = 5.2 and C = 5.5). The following sample characteristics correlated with test measures of memory and information processing (p less than 0.01): age negatively with immediate recall, trail making, incidental episodic memory, focused attention, speed in the CWT; intelligence correlated positively with 10-min adding which relies on working memory (Pauli test) and immediate recall; education correlated positively with delayed recall, visual memory performance in a figures test, immediate recall, and reading speed in the CWT; occupation correlated positively with figures test performance; exercise of profession correlated positively with incidental episodic memory and immediate recall. Age and occupation correlated more with motor measures than with cognitive measures (pegboard, 1 min tapping at maximal speed). Sex had no bearing on memory characteristics, but did on tracking (men better) and color-naming performance in the CWT (women better). Of the semiluxuries, only regular alcohol consumption showed a relationship with the test measures (negatively with color-naming speed, immediate recall, and pegboard performance). Analysis of memory and information processing measures revealed no correlations (r greater than or equal to 0.40) between memory measures from the word list, Pauli test, figures test, and learning. Measures of the CWT correlated with Pauli test and pegboard. ZVT score was the variable with the most correlations (CWT, Pauli test, pegboard). A factor analysis with a reduced set of variables should further clarify the inner structure of our subject's performance.(ABSTRACT TRUNCATED AT 400 WORDS)" @default.
