In industrialized societies, adults exhibit stable preferences for the types of people, animals, and entities they feel moral concern for (Crimston et al., 2016). Only one published study to date has utilized the moral circles paradigm to examine these preferences in children, finding that as children age, their preferences shift to become more…

Although stories for children often feature supernatural and fantastical events, children themselves often prefer realistic events when choosing what should happen in a story. In two experiments, we investigated whether 3- to 5-year-olds (total N = 240 from diverse backgrounds) might be more likely to include fantastical events in stories about…

When making decisions, the amount of time remaining matters. When time horizons are long, exploring unknown options can inform later decisions, but when time horizons are short, exploiting known options should be prioritized. While adults and adolescents adapt their exploration in this way, it is unclear when such adaptation emerges and how…

This study examined preschoolers' social inclusion--the active involvement of new partners into social interactions--in different intergroup contexts. Using an interactive paradigm, 3- to 5-year-old German children played a ball-tossing game with 2 puppets in which 1 puppet initiated the game with the child and another approached the game. In…

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…

Perceptual narrowing occurs in human infants for other-race faces. A paired-comparison task measuring infant looking time was used to investigate the hypothesis that adding emotional expressiveness to other-race faces would help infants break through narrowing and reinstate other-race face recognition. Experiment 1 demonstrated narrowing for White…

Language and accent strongly influence the formation of social groups. By five years of age, children already show strong social preferences for peers who speak their native language with a familiar accent (Kinzler, Shutts, DeJesus, & Spelke, 2009). However, little is known about the factors that modulate the strength and direction of…

Correct counting respects the stable order principle whereby the count terms are recited in a fixed order every time. The 4 experiments reported here tested whether precounting infants recognize and prefer correct stable-ordered counting. The authors introduced a novel preference paradigm in which infants could freely press two buttons to activate…

Preschoolers, as a group, are highly attuned to causality, and this attunement is known to facilitate memory, learning, and problem solving. However, recent work reveals substantial individual variability in the strength of children's "causal stance," as demonstrated by their curiosity about and preference for new causal information. In…

Research has demonstrated that children use different strategies to infer a referent. One of these strategies is to use inflectional morphology. We present evidence that toddlers learning Spanish are capable of using gender word inflections to infer word reference. Thirty-month-olds were tested in a preferential looking experiment. Participants…
