This study showed that 8.5-month-old infants seemed to consider the consistency of an agent's choices in attributing preferences to her. When the agent consistently chose one object over another, three or four times consecutively, infants acted as if they had interpreted her actions as evidence for her preference. In contrast, when the agent inconsistently chose between the two objects, at the ratio of 1:3, infants did not seem to interpret her actions as suggesting her preference. Converging evidence was obtained from infants' responses across a looking-time task and an action task. The results are discussed in terms of how infants might use frequencies of agents' actions directed toward different objects to understand agents' preferences.
这项研究表明，8.5个月大的婴儿在将偏好归因于某个主体时，似乎会考虑该主体选择的一致性。当该主体连续三到四次始终选择某一物体而非另一物体时，婴儿的行为就好像他们把她的行为解读为她偏好的证据。相比之下，当该主体在两个物体之间以1:3的比例做出不一致的选择时，婴儿似乎并没有把她的行为解读为表明她的偏好。通过婴儿在一个注视时间任务和一个动作任务中的反应获得了趋同的证据。研究结果从婴儿如何利用主体针对不同物体的行动频率来理解主体的偏好这一角度进行了讨论。
