We systematically compared beliefs about animal (e.g., "lion"), artifactual (e.g., "hammer"), and institutional (e.g., "police officer") categories, aiming to identify whether people draw different inferences about which categories are subjective and which are socially constituted. We conducted two studies with 270…

The lack of research exploring the influence of dynamic visual narratives on inference skills prompted the present study with an aim to profile the inference skills in school children between the ages of 6 years and 9 years 11 months using dynamic visual narratives. A total of 80 participants were considered for the study. An animated story was…

Two studies examined factors that predicted children's tendencies to match objects versus relations across scenes when no instruction was given. Study 1 examined a) age and b) nationality as a proxy for cultural differences in experiences with relations. The results showed that Chinese and U.S. children across ages all showed an initial bias to…

When and how do children develop an understanding of the subjectivity of intentions? Intentions are subjective mental states in many ways. One way concerns their aspectuality: Whether or not a given behavior constitutes an intentional action depends on how, under which aspect, the agent represents it. Oedipus, for example, intended to marry…

Metaphor development in conjunction with verbal intelligence and linguistic competence in middle childhood and at the transition to early adolescence was investigated. 298 individuals between seven and ten years (chronological age) who attended grades two-four (mental age) were tested for metaphor processing by the Metaphoric Triads Task, for…

A story's space or setting often determines and constrains the actions of its characters. We report on an experiment with 106 children of 7-8 years old in which, using a novel enactment task, we measured children's representation of a story character's movement during story listening. We found that children were more likely to enact movements that…

We investigated "scalar implicature" in adolescents and children with autism spectrum disorder (ASD) to test whether theory of mind deficits associated with autism affect pragmatic inferences in language. We tested scalar implicature computation in adolescents with ASD (12-18 years) and asked whether they reason about mental states when…

Three experiments examined children's and adults' abilities to use statistical and temporal information to distinguish between common cause and causal chain structures. In Experiment 1, participants were provided with conditional probability information and/or temporal information and asked to infer the causal structure of a 3-variable mechanical…

Children's epistemic vigilance was examined for their reasoning about the intentions and outcomes of informants' past testimony. In a 2 x 2 factorial design, 5- and 6-year-olds witnessed informants offering advice based on the intent to help or deceive others about the location of hidden prizes, with the advice leading to positive or negative…

This study examined how informants' traits affect how children seek information, trust testimony, and make inferences about informants' knowledge. Eighty-one 3- to 6-year-olds and 26 adults completed tasks where they requested and endorsed information provided by one of two informants with conflicting traits (e.g., honesty vs. dishonesty).…

Objective: The present study examines the ability of children with ADHD to make inferences and monitor ongoing understanding of texts, to shed light on their academic difficulties. Method: A total of 29 boys with ADHD and 41 comparison boys between the ages of 7 and 12 participated. Three tasks measure how boys create and evaluate inferences,…

We describe the nature of the evidential system in Tibetan and consider the challenges that any evidential system presents to language acquisition. We present data from Tibetan-speaking children that shed light on their understanding of the syntactic and semantic properties of evidentials, and their competence in the point-of-view shift required…

The ability to perform relational proposition-based reasoning was assessed in younger and older adults using the transitive inference task in which subjects learned a series of premise pairs (A greater than B, B greater than C, C greater than D, D greater than E, E greater than F) and were asked to make inference judgments (B?D, B?E, C?E).…

Background: Children with language impairments have difficulty in reporting verbal inferences, but it is unclear whether the source of this problem lies in limitations of language comprehension, an inability to access world knowledge, or the integration of information in discourse. Children with pragmatic language impairments (CwPLI) are often…

Three experiments examined the changes in category representation that take place when children use exemplars for tasks other than classification. In Experiments 1 and 2, 6- and 10-year-old children learned to classify exemplars of a novel category and then used the same exemplars in an inferential prediction task. In a subsequent classification…
