FIG. 1.

JVP Domes and custom probe. (a) The set of 8 domes used in the study. (b) Grid spacing on one dome. (c) Custom holder used to apply pressure. The strain gauges are inside the handle and are not visible. (d) Magnified image of the region marked by the white box in (c).

FIG. 2.

Mean and standard deviation of the proportion correct for each probe averaged across all participants. Chance (0.25) performance (dotted line) was observed for probes with finest grids (#1, #2).

Image of FIG. 3.
FIG. 3.

Proportion correct for every participant and probe (identified by numbers). Most participants had difficulty with probes 1 and 2. All participants were above chance by probe #6. Somatosensory acuity (SAPC) was defined as the best performance (highest proportion correct) across probes for each participant (top open circle in each column). Median split groups are shown in different shades (lighter shade—lower acuity, darker shade—higher acuity).

FIG. 4.

Correlations between standardized contrast distance and somatosensory maximum proportion correct (left), between standardized contrast distance and auditory JND (middle) and between somatosensory maximum proportion correct and auditory JND (right). (-one-tailed, -two-tailed).

Image of FIG. 5.
FIG. 5.

Differences in 3-D contrast distance for said/shed and sid/shid as a function of group based on acuity and vowels (‘eh’ as in said, ‘ih’ as in sid; Groups-b: , ; s: , ; p: , ; n: , ; 1 indicates higher than median, and 0 indicates lower than median).
