Motivational Biases of Behaviour: Role of Serotonin versus Dopamine

When we see a threat, we tend to hold back. When we see a reward, we have a strong urge to approach. Reward or punishment cues bias action, eliciting appetitive activation and/or aversive inhibition, respectively. Such motivational biases of behavior are often considered to reflect cue-based, ‘Pavlovian’ effects, which arise as hardwired responses to learned stimulus-associated outcome predictions. We study the role of catecholamine as well as serotonin transmission in these motivational action biases, which we have shown can in fact arise also from biases in instrumental learning (Swart et al., 2019). Specifically we have tested the motivational opponency hypothesis, according to which serotonin and dopamine play key roles in linking so-called Pavlovian aversive and appetitive predictions with behavioral inhibition and activation, respectively. Moreover, we study the degree to which such motivational biases can transfer to more cognitive learning systems (Piray et al. 2019).
