- Figure 1.
Time line of one test trial of the wheel of fortune game. The green line in the outcome interval indicates pain relief as the outcome of the game, the red line indicates pain increase as the outcome of the game, and the black line indicates no change as the outcome of the game. Thermal stimulation followed the same temperature time course in both the test and the control trials. Instead of playing the game by choosing a color in the button-press interval in the test trials, participants had to press a black button after which the wheel stopped at a random position with no pointer in the control trials. max., Maximum.
- Figure 2.
Means and 95% confidence intervals of behaviorally assessed pain perception for test and control trials in the pain relief, pain increase, and no-change outcomes. Negative values indicate pain sensitization relative to the beginning of each trial, and positive values indicate habituation. post hoc comparisons: *p < 0.017, significant after Bonferroni correction for multiple testing.
- Figure 3.
Means and 95% confidence intervals of perceived pain intensity for test and control trials in the pain relief, pain increase, and no-change outcomes. post hoc comparisons: **p < 0.003, *p < 0.017, significant after Bonferroni correction for multiple testing.
- Figure 4.
Correlation of participants’ scores on the novelty-seeking subscale of the TCI and pain modulation by pain relief obtained by winning, which was calculated as the difference between intensity ratings in the test minus the control trials of the pain relief outcome.
- Figure 5.
Mean amplitudes and 95% confidence intervals of skin conductance responses in the test and control trials in the pain relief, pain increase, and no-change outcomes. post hoc comparisons: t*p < 0.10; **p < 0.003 after Bonferroni correction for multiple testing.
