Abstract
The effects of feedback and instructions on increase of peripheral skin temperature were examined. Sixteen male undergraduate students were assigned to one of four groups: response-specific instructions with feedback (RI-F), response specific instructions without feedback (RI-NF), instructions to rest with simulation feedback (Rest-SF), and instructions to rest without feedback (Rest-NF). All subjects participated in 12 training sessions. Skin temperature on training periods was lower than on rest periods in many subjects. Feedback had interference effects on the performance. That is, temperature in the RI-F group decreased more than in the other three groups during the early sessions. Effects of instructions did not show any clear differences on the control of skin temperature. However, instructions in the RI-F group decreased skin temperature more than in the Rest SF group. Amount of change in skin temperature on the first trial was highly correlated with formance. These results were discussed in terms of the probability of skin temperature control the over-all perwith biofeedback.
