Note. The sample consisted of 78 young adults (28 men, 50 women; range: 18-25) and 77 older adults (14 men, 63 women; range: 60-92). Means are given for trackable participants only (see Method). Standard deviations are noted within parentheses. The following tests were used: self-reported age, estimated years of education ranging from 10 (some high school) to 18 (graduate school) based on self-reported levels of education, self-reported current health, ranging from 1 (poor) to 5 (excellent), Pelli-Robson contrast sensitivity chart (Pelli, Robson & Wilkins, 1988), Rosenbaum pocket vision screener for near vision (Rosenbaum, 1984), Snellen chart for visual acuity, Brief Skin Cancer Risk Assessment Tool (BRAT; Glanz et al., 2003) and Thorough Skin Self-Examination (TSSE; Weinstock et al., 2004). Missing responses are due to technical failures or participants not complying with task instructions for proper assessment. Significance notation indicates significance of the age difference
