This paper summarizes new experiments on compliance discrimination in
which work cues were eliminated and force cues were minimized. The
average JNDs for compliance ranged from 15% to 99% and were much
larger than the average JND (8%, see Tan, Pang & Durlach, 1992)
obtained from previous compliance discrimination experiments in which
both work and terminal force cues, as well as compliance cues, were
available to the subject. By converting results to corresponding JNDs
in terminal force, we obtained a force JND of 5.2% (s.d.  0.8%); this
value was found to be consistent with force JNDs (6-8%, see Pang, Tan
& Durlach, 1991; Tan et al., 1992) we had obtained earlier from force
discrimination experiments. We conclude from these compliance
experiments and our previous experiments on force and compliance
perception that manual resolution of compliance deteriorates when
force and/or work cues are reduced or eliminated.
