説明
<jats:title>Significance</jats:title> <jats:p>When we see a person act (e.g., reach for a cup), we observe physical movements but infer underlying goals. Many have proposed that this ability depends on having produced motor actions oneself. We investigated the relationship between action understanding and production by giving young infants novel experience producing actions. Consistent with prior research, infants exhibited understanding of others’ actions only when they had produced similar actions themselves. However, infants exhibited expectations about action efficiency that went beyond what could be learned from the training, suggesting that some knowledge of goal-directed action precedes this first-person motoric experience.</jats:p>
