However, a blanket inhibition of pain by reward would also impair pain discrimination. In contrast, early counterconditioning experiments implied that reward might actually spare pain discrimination. To test this hypothesis, we investigated whether discriminative performance was enhanced or inhibited by reward. We found in adult human volunteers (N = 25) that pain-based discriminative ability is actually enhanced by reward, especially when reward is directly contingent on discriminative performance. Drift-diffusion modeling shows that this relates to an augmentation of the underlying sensory signal strength and is not merely an effect of decision bias. This enhancement of sensory-discriminative pain-information processing suggests that whereas reward can promote reward-acquiring behavior by inhibition of pain in some circumstances, it can also facilitate important discriminative information of the sensory input when necessary. date: 2020 publisher: Sage (Publ.) id_scheme: DOI id_number: 10.11588/heidok.00029137 official_url: https://doi.org/10.1177/0956797620939588 ppn_swb: 1750442248 own_urn: urn:nbn:de:bsz:16-heidok-291375 language: eng bibsort: BECKERSUSAREWARDENHA2020 full_text_status: public publication: Psychological Science volume: 31 number: 9 place_of_pub: Thousand Oaks, Calif. ; London pagerange: 1191-1199 issn: 0956-7976 (Druck-Ausg.), 1467-9280 (Online-Ausg.) edition: Zweitveröffentlichung citation: Becker, Susanne ; Löffler, Martin ; Seymour, Ben (2020) Reward Enhances Pain Discrimination in Humans.
