Simple versus complex feedback displays in the training of digital temperature.

Trained 15 male volunteers for 2 days to increase their hand temperature; 8 Ss received analog meter feedback and 7 received analog meter feedback plus binary feedback by both lights and tones. All Ss were paid $.25/.1Deg.C change from baseline on each day. As previously reported, it appeared difficult to train digital temperature increases above baseline using feedback and reward.
