‘Motionese’ can be defined as an exaggerated and repetitive action. It induces preference and learning in infants. However, which action component of motionese promotes infants’ preference and learning remains largely unknown. In this study, we focused on inefficiency and toward-ness of action. Our study demonstrates that observing an inefficient holding out action can induce a visual preference in 4-month-old infants and learning in 10-month-old infants through eight experiments (N = 192). We found that when infants observe inefficient holding out action, the action attracts their attention and facilitates learning about the identity of the toy object accompanying it, especially when people direct inefficient actions towards them. Our findings indicate that both action efficiency and toward-ness may be key factors in infant learning.

观察低效的行为可以诱导婴儿的偏好和学习

“Motionese”可以定义为夸张和重复的动作。它引起婴儿的偏好和学习。然而，motionese 的哪个动作成分促进了婴儿的偏好和学习仍然很大程度上未知。在这项研究中，我们关注的是低效率和行动的倾向性。我们的研究表明，通过 8 次实验（N = 192)。我们发现，当婴儿观察到低效的坚持动作时，该动作会吸引他们的注意力并有助于了解伴随它的玩具物体的身份，尤其是当人们将低效的动作指向他们时。我们的研究结果表明，行动效率和倾向性可能是婴儿学习的关键因素。
