Research Article Can a Self-Propelled Box Have a Goal? Psychological Reasoning in 5-Month-Old Infants

ABSTRACT—Some researchers have suggested that infants’ ability to reason about goals develops as a result of their experiences with human agents and is then gradually ex-tended to other agents. Other researchers have proposed that goal attribution is rooted in a specialized system of reasoning that is activated whenever infants encounter en-tities with appropriate features (e.g., self-propulsion). The first view predicts that young infants should attribute goals to human but not other agents; the second viewpredicts that young infants should attribute goals to both human and nonhuman agents. The present research revealed that 5-month-old infants (the youngest found thus far to attribute goals to human agents) also attribute goals to nonhuman agents. Intwoexperiments, infants interpretedtheactionsof a self-propelled box as goal-directed. These results provid
