“…In line with this interpretation, the effect of predictability on cardiac deceleration decreased linearly with the participants' depressive symptoms. This echoes recent findings on the blunted cardiovascular reactivity in depression (Salomon et al, 2013, Messerotti Benvenuti et al, 2015, accompanying diminished social motivation (Grèzes et al, 2023).…”

“…Consistent with our previous studies (Grèzes et al, 2021(Grèzes et al, , 2023Mennella et al, 2020;Vilarem et al, 2020), participants spontaneously chose to enter the elevator without the angry avatar more often than by chance. This confirms that our virtual environment was capable of motivating avoidance behavior, despite its increased complexity compared to previous tasks.…”

“…These avoidance decisions followed a rapid value-comparison process, sourced in the ventromedial prefrontal cortex and orbitofrontal cortex, which are involved in value-based decision-making (Mennella et al, 2020). Furthermore, avoidance decisions were influenced by the individual's affective and motivational state (Grèzes et al, 2021(Grèzes et al, , 2023. However, although these results are consistent with the idea that emotional displays orient behavior by modifying the value of action opportunities (rather than eliciting a fixed response pattern), they do not rule out the possibility that GD processes intervene later to refine an initial SR tendency.…”

Adaptative action selection in threatening social contexts, for example when facing aggressive individuals, is core to social behavior. It is debated whether, when facing threat, initial action opportunities are mostly determined by automatic action tendencies – i.e., reactive stimulus-response (SR) associations – or by rapid and implicit goal-directed (GD) processes, which depend on the predicted consequences of available actions. To investigate the balance between SR and GD, we conducted three experiments manipulating the predictability of action-outcomes associations, in a novel approach-avoidance decision task in virtual reality. Participants presented a greater avoidance rate from angry individuals when the action-outcome association was predictable. Computationally, this was subtended by more efficient evidence accumulation, as indicated by an increased drift rate. Furthermore, cardiac deceleration around the time of choice was greater in the predictable condition and allowed the value attributed to the outcome to be better integrated into the decision. Finally, while most participants avoided angry individuals only under predictability, supporting a predominant role of GD processes, a minority of them avoided regardless of predictability. Overall, our results shed light on the computational architecture of social avoidance, opening interesting new research and clinical perspectives.
