The ability to decide whether, when and how to try is central to human learning. We investigated whether infants can make rational inferences about when and how to try on a novel problem-solving task. After learning from an adult that the task was either easy, difficult or impossible to solve, infants varied in whether, when and how they tried based on the type of social evidence that they received and on their own ongoing experience with the task. Specifically, infants formed expectations about...

Abstract Infants’ persistence in the face of challenges predicts their learning across domains. In older children, linguistic input is an important predictor of persistence: when children are praised for their efforts, as opposed to fixed traits, they try harder on future endeavors. Yet, little is known about the impact of linguistic input as individual differences in persistence are first emerging, during infancy. Based on a preliminary investigation of the CHILDES database, which revealed that...

Abstract Infants’ pointing gestures are clear and salient markers of their interest. As a result, they afford infants with a targeted and precise way of eliciting information from others. The current study investigated whether, similar to older children’s question asking, infants’ pointing gestures are produced to obtain information. Specifically, in a single experimental study, we examined whether 18-month-olds ( N = 36) point to request specific types of information and how this translates int...

Persistence is central to outcomes across a range of domains: the harder you try, the further you get. Yet relatively little is known about the developmental origins of persistence. Here, we highlight key reasons for a surge of interest in persistence in infancy and early childhood.

Abstract Cost-benefit analyses are central to mature decision-making and behavior across a range of contexts. Given debates regarding the nature of infants’ prosociality, we investigated whether 18-month-old infants’ (N = 160) prosocial behavior is impacted by anticipated costs and benefits. Infants participated in a helping task in which they could carry either a heavy or light block across a room to help an experimenter. Infants’ helping behavior was attenuated when the anticipated physical co...

Infants’ early gaze alternations are one of their first steps towards a sophisticated understanding of the social world. This ability, to gaze alternate between an object of interest and another individual also attending to that object, has been considered foundational to the development of many complex social-cognitive abilities, such as theory of mind and language. However, to understand the evolution of these abilities, it is important to identify whether and how gaze alternations are used an...

Infants' pointing gestures are a critical predictor of early vocabulary size. However, it remains unknown precisely how pointing relates to word learning. The current study addressed this question in a sample of 108 infants, testing one mechanism by which infants' pointing may influence their learning. In Study 1, 18-month-olds, but not 12-month-olds, more readily mapped labels to objects if they had first pointed toward those objects than if they had referenced those objects via other communica...
