TLDR

Detecting animate entities, especially those exhibiting self‑propelled motion, has been crucial for human survival throughout evolution. The study tests whether animate motion attracts visual attention. Researchers compared detection times for targets moving predictably due to collisions (inanimate) versus unpredictably (animate) across experiments. Targets with animate motion were detected faster than inanimate ones, and this effect was attributed to perceived animacy rather than display uniqueness or top‑down strategies.

Abstract

Across humans’ evolutionary history, detecting animate entities in the visual field (such as prey and predators) has been critical for survival. One of the defining features of animals is their motion—self-propelled and self-directed. Does such animate motion capture visual attention? To answer this question, we compared the time to detect targets involving objects that were moving predictably as a result of collisions (inanimate motion) with the time to detect targets involving objects that were moving unpredictably, having been in no such collisions (animate motion). Across six experiments, we consistently found that targets involving objects that underwent animate motion were responded to more quickly than targets involving objects that underwent inanimate motion. Moreover, these speeded responses appeared to be due to the perceived animacy of the objects, rather than due to their uniqueness in the display or involvement of a top-down strategy. We conclude that animate motion does indeed capture visual attention.
