(A) Detection thresholds (mean ± SE and individual data) for younger and older adults, separately for each digit (D1–D5). The initially obtained stimulus intensities for each digit, representing the tactile detection thresholds, were logarithmically transformed (log100.1mg) before proceeding with further analysis. For the ANOVA with the factors digit and age on tactile detection thresholds, we obtained a main effect of digit (F(4,192)=9.81, p<0.001), a main effect of age (F(1,38)=48.56, p<0.001), and an interaction between age and digit (F(4,192)=5.16, p<0.01). Post hoc tests revealed that the main effect of digit was due to higher detection threshold for D1 compared to D4 (t(88.82) = 2.58, p<0.05), for D1 compared to D5 (t(91.97) = 2.49, p<0.05), for D2 compared to D4 (t(98)=2.42, p<0.05), and for D2 compared to D5 (t(98)=2.33, p<0.05). The main effect of age was due to significantly higher detection thresholds for older compared to younger adults (younger: mean = 0.80 ± 0.04, older: mean = 1.37 ± 0.07, t(35.83) = 6.97, p<0.001). (B) Response amplitudes of the area 3b finger map in response to maximal (and identical) amplitude stimulation to all fingers of the right hand at once. Older adults showed significantly higher response amplitudes compared to younger adults (younger: 1.05 ± 0.01, older: 1.08 ± 0.008, t(34)=-2.10, p<0.05). (C) Correlations between detection thresholds (see A) and response amplitudes (see B) within the groups of younger and older adults were not significant (i.e. p>0.15).
