Average behavior results in comparison between SF or NF.(a) accuracy and (b) response time. Position: discriminating electrotactile position, and its accuracy is given by A C _p . Type: discriminating the electrotactile type, and its accuracy is given by A C _t . Strength: discriminating the electrotactile strength, and its accuracy is given by A C _s . All: discriminating all the three electrotactile patterns, and its accuracy is given by A C _a . The symbol ∗ between two bars * indicates statistical significance at the p=0.05 level. Error bars depict the standard deviation.
