Description
Qiwei Zhao and Chenglin Zhou studied how experts predict action from body movement in 2026. The same intent can produce varied movement, which makes prediction hard. Skill often helps people anticipate, but weak movement signals may shrink that help.
They define a measure of how readable a movement is, based on its distance from the best decision edge in feature space. In a table-tennis task, experts beat novices when movements were highly readable. Their internal weights also matched the best encoding direction more closely. When readability was low, the expert edge faded, and experts leaned more on prior expectations. The work shows that skill in prediction depends on the strength of the signal itself.
