As adults, we know that others' mental states, such as beliefs, guide their behavior and that these mental states can deviate from reality. Researchers have examined whether young children possess adult-like theory of mind by focusing on their understanding about others' false beliefs. The present research revealed that 10-month-old infants seemed…

We present an introduction to Bayesian inference as it is used in probabilistic models of cognitive development. Our goal is to provide an intuitive and accessible guide to the "what", the "how", and the "why" of the Bayesian approach: what sorts of problems and data the framework is most relevant for, and how and why it may be useful for…

Research suggests that concepts are distributed across brain regions specialized for processing information from different sensorimotor modalities. Multimodal semantic models fall into one of two broad classes differentiated by the assumed hierarchy of convergence zones over which information is integrated. In shallow models, communication within-…

A recent study by Apperly et al. (2006) found evidence that adults do not automatically infer false beliefs while watching videos that afford such inferences. This method was extended to examine true beliefs, which are sometimes thought to be ascribed by "default" (e.g., Leslie & Thaiss, 1992). Sequences of pictures were presented in which the…

Humans are adept at inferring the mental states underlying other agents' actions, such as goals, beliefs, desires, emotions and other thoughts. We propose a computational framework based on Bayesian inverse planning for modeling human action understanding. The framework represents an intuitive theory of intentional agents' behavior based on the…

Reorientation tasks, in which disoriented participants attempt to relocate objects using different visual cues, have previously been understood to depend on representing aspects of the global organisation of the space, for example its major axis for judgements based on geometry. Careful analysis of the visual information available for these tasks…

Examined reasoning about physics principles within and across ontological kinds among 5- and 7-year-olds and adults. Found that all age groups tended to appropriately generalize what they learned across ontological kinds. Children assumed that principles learned with reference to one ontological kind were more likely to apply within that kind than…

Suggests that in learning and development, the process of comparison can act as a bridge between similarity-based and rule-based processing. A structure-sensitive comparison process, triggered by experiential or symbolic juxtapositions can: (1) facilitate understanding of structural commonalities and the abstraction of rules; and (2) facilitate…

Two experiments examined preschoolers' performance on test relying on the uniqueness principle for using evidence from a miscount in inferring a counterfactual cardinal number, with subtests probing associated number-skills. All the 5-year-olds and half the preschoolers passed the test. Results suggest that a crucial preschool step is to start…

Examined preschoolers' inductive inferences across biological and non-biological kinds. Found support for gradual-enrichment model of conceptual change. Four-year-olds had a limited, coherent, independent biological theory which may form the basis of mature understanding of biological kinds. Explored results in terms of multiple explanatory…

Children ages 3 to 5 years old are observed in a series of 3 experiments assessing their use of counterfactual thinking in causal reasoning. Results suggest that young children readily interpret the cause of an outcome in terms of a contrast between the observed sequence of events, and a counterfactual alternative in which the outcome did not…

Three experiments explored the conditions under which inductive inferences about people were made by children and adults. Results indicated that children often predicted that people would behave differently in the future than they did in the past. Younger children limited predictions of consistency to non-psychological events. Older children…
