Children’s exploration distinguishes necessary and merely possible outcomes.
Preschoolers often fail tasks that require that they select between a necessary and a merely possible outcome. Prior work has interpreted these failures as evidence that children hold a minimal representation of possibility or as reflecting performance factors. However, all previous paradigms have operationalized children's modal understanding as a discrete choice or outcome, making it difficult to distinguish between these accounts. We introduce…
Can Childhood be Used as a Model to Understand the Effects of Psychedelics?
Psychedelic drugs have shown promise as a novel therapeutic for a variety of health conditions, yet the mechanisms underlying their clinical benefits remain unclear. A leading hypothesis suggests that psychedelics may enhance cognitive flexibility, a trait impaired in many of these conditions. While existing data from self‐report and qualitative‐interview studies support this hypothesis, data from experimental studies are limited and inconsistent…
Active navigation enhances children’s spatial but not episodic memory
This paper uses a Yoked experimental design to investigate the selective advantage of active spatial navigation in 4- to 10-year-old children. Participants were presented with a map game in which they were asked to find the shortest way for a monster to get across town while collecting its five monster friends on the way. Active control was associated with better recall for path length and the area between paths, whereas no differences were obser…
Schema drift
Analogical reasoning is one of the most common ways individuals bring previous experience to bear on unfamiliar situations. Most theories describe this process as a structured comparison that involves mapping the relational properties between a familiar source and unfamiliar target. This both allows the transfer of useful inferences from the source to the target and highlights the common structure shared by both analogs, represented by an abstrac…
Children’s developing ability to predict novel outcomes from variability information
Making abstract inferences from specific instances is a critical cognitive ability. Here, we examine children's capacity to use these inferences to reason beyond the evidence they observe. In three experiments, participants ( N = 161, 46% female, 43% White) observed various colored balls randomly drawn from two opaque boxes and were asked to choose which box was more likely to contain a novel-colored ball. Younger preschoolers ( M age = 40.12 mon…
Children’s recognition of causal system categories across superficially distinct events
A deep understanding of any phenomenon requires knowing how its causal elements are related to one another. Here, we examine whether children treat causal structure as a metric for assessing similarity across superficially distinct events. In two experiments, we presented 156 4-7-year-olds (approximately 55% of participants identified as White, 29% as multiracial, and 12% as Asian) with three-variable narratives in which story events unfold accor…
Learners’ causal intuitions explain behavior in control of variables tasks
Self-directed learners are described as "intuitive scientists," yet they often struggle in assessments of their scientific reasoning skills. We investigate a novel explanation for this apparent gap between formal and informal scientific inquiry behavior. Specifically, we consider whether learners' documented failure to correctly apply the control of variables strategy might stem from a mismatch between task presentation and their intuitions as ca…
Thinking Structurally
To make accurate causal inferences about social-group inequalities, people must consider structural causes. Structural causes are a distinct type of extrinsic cause—they are stable, interconnected societal forces that systematically advantage some social groups and disadvantage others. We propose a new cognitive framework to specify how people attribute inequality to structural causes. This framework is rooted in counterfactual theories of causal…
Visual explanations prioritize functional properties at the expense of visual fidelity
Explanation impacts hypothesis generation, but not evaluation, during learning
A large body of research has shown that engaging in self-explanation improves learning across a range of tasks. It has been proposed that the act of explaining draws attention and cognitive resources towards evidence that supports good explanations-information that is broad, abstract, and consistent with prior knowledge-which in turn aids discovery and promotes generalization. However, it remains unclear whether explanation impacts the learning p…
You can’t change the past
This study explored children's causal reasoning about the past and future. U.S. adults (n = 60) and 3-to-6-year-olds (n = 228) from an urban, middle-class population (49% female; ~45% white) participated between 2017 and 2019. Participants were told three-step causal stories and asked about the effects of a change to the second event. Given direct interventions on the second event, children of all ages judged that the past event still occurred, s…
Children acknowledge physical constraints less when actors behave stereotypically
A fundamental part of understanding structural inequality is recognizing that constrained choices, particularly those that align with societal stereotypes, are poor indicators of a person's desires. This study examined whether children (N = 246 U.S. children, 53% female; 61% White, 24% Latinx; 5–10 years) acknowledge constraints in this way when reasoning about gender-stereotypical choices, relative to gender-neutral and gender-counterstereotypic…
Children’s Developing Ability to Resolve Disagreements by Integrating Perspectives
Children live in a world where disagreement is commonplace. Although disagreement can sometimes be explained by differences in people’s reliability, disagreement may also indicate that the referent elicits multiple perspectives. The present studies (total N = 129, 5- to 12-year-old ethnically diverse U.S. children, 42% girls) examined children’s ability to resolve disagreement among two individuals by identifying referents that integrated the per…
Thinking Counterfactually Supports Children’s Evidence Evaluation in Causal Learning
Often, the evidence we observe is consistent with more than one explanation. How do learners discriminate among candidate causes? The current studies examine whether counterfactuals help 5-year olds (N = 120) select between competing hypotheses and compares the effectiveness of these prompts to a related scaffold. In Experiment 1, counterfactuals support evidence evaluation, leading children to privilege and extend the cause that accounted for mo…
Toddlers learn and flexibly apply multiple possibilities
The ability to consider multiple possibilities forms the basis for a wide variety of human-unique cognitive capacities. When does this skill develop? Previous studies have narrowly focused on children's ability to prepare for incompatible future outcomes. Here, we investigate this capacity in a causal learning context. Adults (N = 109) and 18- to 30-month olds (N = 104) observed evidence that was consistent with two hypotheses, each occupying a d…
Informative experimentation in intuitive science
Achieving abstraction
Analogical reasoning is essential for transfer by supporting recognition of relational similarity. However, not all analogies are created equal. The source and target can be similar (near), or quite different (far). Previous research suggests that close comparisons facilitate children's relational abstraction. On the other hand, evidence from adults indicates that the process of solving far analogies may be a more effective scaffold for transfer …
Pretense and possibility—A theoretical proposal about the effects of pretend play on development
The review by Lillard et al. (2013) highlighted the need for additional research to better clarify the nature of the relationship between pretend play and development. However, the authors did not provide a proposal for how to structure the direction of this future work. Here, we provide a possible framework for generating additional research. This theoretical proposal is based on recent computational approaches to cognition, in which counterfact…
The role of symbol-based experience in early learning and transfer from pictures
Extensive exposure to representational media is common for infants in Western culture, and previous research has shown that soon after their 1st birthday, infants can acquire and extend new information from pictures to real objects. Here we explore the extent to which lack of exposure to pictures during infancy affects children's learning from pictures. Infants were recruited from a rural village in Tanzania and had no prior experience with pictu…
Engagement in philosophical dialogue facilitates children’s reasoning about subjectivity
Theories of learning have long emphasized the essential role of social factors in the development of early reasoning abilities. More recently, it has been proposed that the presentation of conflicting perspectives may facilitate young children's understanding of knowledge claims as potentially subjective-one of many possible representations of the world. This development in epistemological understanding has been proposed to be an important determ…
