Children's cost-benefit analysis about agents who act for the greater good
School-age children are more skeptical of inaccurate robots than adults
Testimony and observation of statistical evidence interact in adults' and children's category-based induction
Rational learners and parochial norms
Parochial norms are narrow in social scope, meaning they apply to certain groups but not to others. Accounts of norm acquisition typically invoke tribal biases: from an early age, people assume a group's behavioral regularities are prescribed and bounded by mere group membership. However, another possibility is rational learning: given the available evidence, people infer the social scope of norms in statistically appropriate ways. With this pape…
Culture moderates the relationship between self-control ability and free will beliefs in childhood
We investigate individual, developmental, and cultural differences in self-control in relation to children's changing belief in "free will" - the possibility of acting against and inhibiting strong desires. In three studies, 4- to 8-year-olds in the U.S., China, Singapore, and Peru (N = 441) answered questions to gauge their belief in free will and completed a series of self-control and inhibitory control tasks. Children across all four cultures …
Leaving a Choice for Others
People value those who act with others in mind even as they pursue their own goals. Across three studies (N = 566; 4- to 6-year-olds), we investigated children’s developing understanding of such considerate, socially-mindful actions. By age 6, both U.S. and Chinese children positively evaluate a character who takes a snack for herself in a way that leaves a snack choice for others over a character who leaves no choice (Study 1), but only when the…
The choice is yours
Our social world is rich with information about other people's choices, which subsequently inform our inferences about their future behavior. For individuals socialized within the American cultural context, which places a high value on autonomy and independence, outcomes that are the result of an agent's own choices may hold more predictive value than similar outcomes that are the result of another person's choices. Across two experiments we test…
Selectivity in toddlers’ behavioral and emotional reactions to prosocial and antisocial others
Whereas some evidence suggests that toddlers consider targets' deservingness when deciding whom to help, other research demonstrates that toddlers help indiscriminately. The present findings shed light on this discrepancy by demonstrating that although toddlers do exhibit selectivity in giving behaviors, their emotional responses are comparatively indiscriminate. Specifically, in Experiment 1, 20-month-olds (N = 64) were more likely to give prefe…
What I don’t know won’t hurt you
Testimony is a valuable source of information for young learners, in particular if children maintain vigilance against errors while still being open to learning from imperfectly knowledgeable sources. We find support for this idea by examining how children evaluate individual speakers who present very different epistemic risks by being previously ignorant or inaccurate. Results across 2 experiments show that children attribute knowledge to (Exper…
Infants Use Statistical Sampling to Understand the Psychological World
Preverbal infants engage in statistical and probabilistic inference to learn about their linguistic and physical worlds. Do they also employ probabilistic information to understand their social world? Do they infer underlying causal mechanisms from statistical data? Here, we show, with looking‐time methods, that 10‐month‐olds attend to statistical information to understand their social–psychological world and plausibly infer underlying causal mec…
When what’s inside counts
This study explores the role of a particular social cue-the sequence of demonstrated actions and events-in preschooler's categorization. A demonstrator sorted objects that varied on both a surface feature (color) and a nonobvious property (sound made when shaken). Children saw a sequence of actions in which the nonobvious property was revealed before (shake-first) or after (shake-last) categorization. Four experiments (N = 150) showed that both 4…
Social context effects in 2- and 4-year-olds’ selective versus faithful imitation
This study asked whether children's tendency to imitate selectively (ignore causally unnecessary actions) versus faithfully (overimitate causally unnecessary actions) varies across ages and social contexts. In the first experiment, 2-year-olds and 4-year-olds were randomly assigned to play 1 of 3 prior games with a demonstrator: a mimicry game, an instrumental game, or a noninteractive control game. They then participated in a puzzle-box imitatio…
Who can help me fix this toy?” The distinction between causal knowledge and word knowledge guides preschoolers' selective requests for information
Preschoolers use outcomes of actions to infer causal properties of objects. We asked whether they also use them to infer others' causal abilities and knowledge. In Experiment 1, preschoolers saw 2 informants, 2 tools, and 2 broken toys. One informant (the labeler) knew the names of the tools, but his actions failed to activate the toys. The other (the fixer) was ignorant about the names of the tools, but his actions succeeded in activating the to…
A self-agency bias in preschoolers' causal inferences
Preschoolers' causal learning from intentional actions--causal interventions--is subject to a self-agency bias. The authors propose that this bias is evidence-based, in other words, that it is responsive to causal uncertainty. In the current studies, two causes (one child controlled, one experimenter controlled) were associated with one or two effects, first independently, then simultaneously. When initial independent effects were probabilistic, …
Conditional probability versus spatial contiguity in causal learning
This study examines preschoolers' causal assumptions about spatial contiguity and how these assumptions interact with new evidence in the form of conditional probabilities. Preschoolers saw a toy that activated in the presence of certain objects. Children were shown evidence for the toy's activation rule in the form of patterns of probability: The toy was more likely to activate either when objects made contact with its surface (on condition) or …
A Theory of Causal Learning in Children
The authors outline a cognitive and computational account of causal learning in children. They propose that children use specialized cognitive systems that allow them to recover an accurate "causal map" of the world: an abstract, coherent, learned representation of the causal relations among events. This kind of knowledge can be perspicuously understood in terms of the formalism of directed graphical causal models, or Bayes nets. Children's causa…
