Subjective Rating
To test whether different kinds of tactile stimulations impacted the
perceived pleasantness, subjective ratings were analyzed by means of a
2-way repeated-measures ANOVA with Touch type (CT-optimal vs.
CT-suboptimal) and Hand type (Human vs. Artificial) as within subject
factors. Post-hoc analyses following significant main effects and
interactions were performed by running two-tailed pairwise t-tests, and
multiple comparisons were corrected by means of FDR. All p values
< 0.05 were considered significant.
