Abstract
ROC curves were obtained by the rating-scale method for the detection of brief mechanical pulses presented to the finger and dorsal forearm to study differences in detection processes at the two sites. An adaptive psychophysical procedure was successful in equating detectability at the two sites when data were averaged across sessions. Criteria adopted by the Os appeared to depend on locus of stimulation, since fewer false alarms were given at the arm than at the finger. These findings were discussed with respect to continuous and multistate detection models.
