The online-VAAST: A short and online tool to measure spontaneous approach and avoidance tendencies.

Among the great variety of approach/avoidance tasks, the Visual Approach/Avoidance by the Self Task (VAAST, Rougier et al., 2018) appears to be a promising tool. Previous work showed that the VAAST leads to large and replicable compatibility effects (e.g., faster response time to approach positive stimuli and avoid negative stimuli than the reverse). In the present contribution, we provide an online and easy-to-use version of the VAAST (namely, the online-VAAST). Across four experiments, we show that the online-VAAST produces effects that are of similar magnitude to those of the lab version of this task. Specifically, we obtained compatibility effects when using positive/negative words (Experiment 1), positive/negative images (Experiment 2), French/North-African first names (Experiment 3), and European American/African American first names (Experiment 4). Moreover, these effects emerged with culturally different populations (i.e., Americans in Experiments 1, 2, and 4, French in Experiment 3). Overall, the online-VAAST could be of great interest for all researchers interested in measuring approach/avoidance tendencies: Its specificities allow reaching large samples both offline and online with no accessibility constraints regarding programming abilities or program copyright.
