“…For the 25-Hz data (Figure 3), the standard errors of the mean (Alf & Grossberg, 1979) for the younger group ranged from .01 to 7.0; for the older group, they ranged from .01 to 6.9. For the 250-Hz data (Figure 4), the standard errors for the younger group ranged from .02 to 3.37; for the older group, they ranged from .02 to 2.34.…”

The psychophysical responses to vibration of two age groups (22 or 25 and 66 years) were compared for two tasks using suprathreshold levels of vibrotactile stimulation. At a vibration frequency of 25 Hz, the two age groups gave similar curves of subjective magnitude determined by the method of absolute magnitude estimation. At 250 Hz, the curve of the older group showed no recruitment over low levels of intensity. Instead, their magnitude estimates were depressed over the entire range of intensities. Sensory persistence, measured by a matching procedure, was more marked in the older group.The effect of aging upon the absolute detection threshold for vibration has been reported in a number of publications (
