Approach aversion: negative hedonic reactions toward approaching stimuli.

We live in a dynamic world, surrounded by moving stimuli-moving people, moving objects, and moving events. The current research proposes and finds an approach aversion effect-individuals feel less positively (or more negatively) about a stimulus if they perceive it to be approaching rather than receding or static. The effect appears general, occurring whether the stimulus is initially negative or nonnegative and whether it moves in space (toward or away from "here"), in time (toward or away from "now"), or in probability (toward or away from "sure"). This research complements extensive existing research on perceived static distance of stimuli (near vs. far) by exploring perceived dynamic movement of stimuli (approaching vs. receding), showing that the effect of movement is distinct from the effect of distance.
