Fig. 1.

Schematic drawing of the events shown in Exps. 1 and 2. In Exp. 1, the can and box were either self-propelled and agentive (A) or neither self-propelled nor agentive (B). In Exp. 2, the can and box were self-propelled and agentive (A), self-propelled but nonagentive (C), or nonself-propelled but agentive (D). Whether the can trial or the box trial was shown first in the familiarization (A–D), pretest (E), and test (F) trials was counterbalanced across infants in each condition; whether the can or the box was hollow in the test trials was also counterbalanced across infants in each condition.
