What a Relief! Successful Threat Avoidance Is Similar to Receiving a Reward

Cues representing monetary values/electrical stimuli of different magnitudes were presented. Successful responses to them engendered monetary gains (reward)/electrical stimulation omissions (relief). For reward and relief similarly, higher magnitudes elicited more successful responses, higher pleasantness ratings, and higher physiological arousal. Differential reward/relief response patterns predicted decisions when choosing between them.
