Participant Characteristics

Measure Mean (SD) r with age
Education (years) 17.336 (2.429) −0.027
MMSE 29.541 (0.621) 0.004
BDI 2.590 (3.100) 0.145
Vocabulary 58.344 (4.604) 0.007
Color Vision 13.869 (0.499) −0.239
Corrected Visual Acuity −0.010 (0.087) 0.393

Note. n = 61; values are presented as mean (standard deviation, SD); MMSE = score on the Mini-Mental State Exam (Folstein et al., 1975); BDI = score on the Beck Depression Inventory (Beck, 1978); Vocabulary = raw score on the vocabulary subtest of the Wechsler Adult Intelligence (WAIS) Scale III (Wechsler, 1997); Color Vision = score on Dvorine color plates (Dvorine, 1963); Corrected Visual Acuity = logarithm of the minimum angle of resolution (MAR), for the Freiburg Visual Acuity Test (Bach, 1996). A log MAR score of 0 corresponds to Snellen 20/20, with negative values indicating better resolution. Thus, the positive correlation for acuity represents age-related decline in this measure. Significant effects are presented in bold.
