Toddlers Prefer Agents Who Help Those Facing Harder Tasks
Capacities to understand and evaluate others’ actions are fundamental to human social life. Infants and toddlers are sensitive to the costs of others’ actions, infer others’ values from the costs of the actions they take, and prefer those who help others to those who hinder them, but it is largely unknown whether and how cost considerations inform early understanding of third-party prosocial actions. In three experiments (N = 94), we asked whethe…
Perceptual and conceptual novelty independently guide infant looking behaviour
An asynchronous, hands-off workflow for looking time experiments with infants
The study of infant gaze has long been a key tool for understanding the developing mind. However, labor-intensive data collection and processing limit the speed at which this understanding can be advanced. Here, we demonstrate an asynchronous workflow for conducting violation-of-expectation (VoE) experiments, which is fully "hands-off" for the experimenter. We first replicate four classic VoE experiments in a synchronous online setting, and show …
Knowing before doing
The relationship between experience and knowledge is one of the oldest and deepest questions in psychology. In developmental science, research on this question has focused on prereaching infants who cannot yet retrieve objects by reaching for and grasping them. Over the past 2 decades, behavioral research in this population has produced two seemingly contradictory findings: After first-person experience with reaching via "sticky mittens" training…
Dangerous Ground
Do infants appreciate that other people’s actions may fail, and that these failures endow risky actions with varying degrees of negative utility (i.e., danger)? Three experiments, including a pre-registered replication, addressed this question by presenting 12- to 15-month-old infants (N = 104, 52 female, majority White) with an animated agent who jumped over trenches of varying depth towards its goals. Infants expected the agent to minimize the …
Ten-month-old infants infer the value of goals from the costs of actions
Ranking valuations on the basis of observed choices Obliged to make a choice between two goals, we evaluate the benefits of achieving the goals compared with the costs of the actions required before deciding what to do. This seems perfectly straightforward, and it is unsurprising to learn that we can also apply this reasoning to others; that is, someone that we see choosing a goal that requires a more costly action must value that goal more highl…
