Approach-avoidance conflict is observed in the competing motivations towards the benefits and away from the costs of a decision. The current study employs the action dynamics of response motion, via mouse-tracking, in an attempt to characterize the continuous dynamic resolution of such conflicts. Approach-avoidance conflict (AAC) was generated by varying the appetitive consequences of a decision (i.e., point rewards and shorter participation time) in the presence of a simultaneous aversive consequence (i.e., shock probability). In two experiments, we found that AAC differentially affected response trajectories. Overall, approach trajectories were less complex than avoidance trajectories. As approach and avoidance motivations neared equipotentiality, response trajectories were more deflected from the shortest route to the eventual choice. Consistency in the location of approach and avoidance response options reduced variability in performance enabling more sensitive estimates of dynamic conflict. The time course of competing influences on response trajectories including trial-to-trial effects and conflict between approach and avoidance were estimated using regression analyses. We discuss these findings in terms of a dynamic theory of approach-avoidance that we hope will lead to insights of practical relevance in the field of maladaptive avoidance.

A fundamental study on the mechanism of the s-BuLi/chiral diamine-mediated asymmetric lithiation-trapping of N-thiopivaloyl azetidine and pyrrolidine has revealed that the asymmetric induction is due to a dynamic resolution of configurationally unstable organolithiums.
