In this pain study, conducted after approval by our Institutional Review Board, we induced placebo analgesia to test whether this also reduces empathy for pain. Additionally, we evaluated how individual differences in personality traits measured by the revised Reinforcement Sensitivity Theory-Personality Questionnaire (RST-PQ, Corr and Cooper, 2016) modulate pain perception and placebo analgesia during a first-hand experience of pain and empathy for pain. Subjective and electrocortical measures of pain and empathy for pain were collected using self-report and event-related potentials (ERPs) while participants experienced painful electrical stimulation or witnessed that another person was experiencing such stimulation. Although our data supported a significant placebo effect on pain perception, they did not support a reduction on empathy for pain. Higher N1 amplitude was associated with higher Goal Drive Persistence and Reward Interest measures. Higher P2 amplitude was associated with lower Impulsiveness levels in the central region of the scalp and with higher Behavioral Inhibition System levels in the frontal lobe.

Abstract
In this pain study, conducted after approval by our Institutional Review Board, we induced placebo analgesia to test whether this also reduces empathy for pain. Additionally, we evaluated how individual differences in personality traits measured by the revised Reinforcement Sensitivity Theory-Personality Questionnaire (RST-PQ, Corr and Cooper, 2016) modulate pain perception and placebo analgesia during a first-hand experience of pain and empathy for pain. Subjective and electrocortical measures of pain and empathy for pain were collected using self-report and event-related potentials (ERPs) while participants experienced painful electrical stimulation or witnessed that another person was experiencing such stimulation. Although our data supported a significant placebo effect on pain perception, they did not support a reduction on empathy for pain. Higher N1 amplitude was associated with higher Goal Drive Persistence and Reward Interest measures. Higher P2 amplitude was associated with lower Impulsiveness levels in the central region of the scalp and with higher Behavioral Inhibition System levels in the frontal lobe.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
