The present study tested the hypothesis that verbal labels support category induction by providing compact hypotheses. Ninety-seven 4- to 6-year-old children (M = 63.2 months; 46 female, 51 male; 77% White, 8% more than one race, 4% Asian, and 3% Black; tested 2018) and 90 adults (M = 20.1 years; 70 female, 20 male) in the Midwestern United States…

Previous studies showed that word learning is affected by children's existing knowledge. For instance, knowledge of semantic category aids word learning, whereas a dense phonological neighbourhood impedes learning of similar-sounding words. Here, we examined to what extent children associate similar-sounding words (e.g., rat and cat) with objects…

How do children infer the meaning of a novel verb? One prominent proposal is that children rely on syntactic information in the linguistic context, a phenomenon known as "syntactic bootstrapping". For example, given the sentence "The bunny is gorping the duck," a child could use knowledge of English syntactic roles to infer…

While creativity anxiety has been found to have negative relationships with various creative outcomes, whether creativity anxiety would also negatively influence creative cognitive styles (i.e. idea generation; idea selection) and the mechanisms underlying these impacts are still unknown. Based on the Self-Efficacy Theory (SET) and the Dual…

One cue that may facilitate children's word learning is iconicity, or the correspondence between a word's form and meaning. Some have even proposed that iconicity in the early lexicon may serve to help children learn how to learn words, supporting the acquisition of even noniconic, or "arbitrary," word-referent associations. However,…

Previously rewarding experiences can influence choices in new situations. Past work has demonstrated that existing reward associations can either help or hinder future behaviors and that there is substantial individual variability in the transfer of value across contexts. Developmental changes in reward sensitivity may also modulate the impact of…

Children with autism spectrum disorder often demonstrate difficulty communicating with others, and this may affect the extent to which they can engage in contextually appropriate language during play. This study examined the effects of a social script-training intervention using generic picture cues on the number of contextually appropriate play…

Children learn words in ambiguous situations, where multiple objects can potentially be referents for a new word. Yet, researchers debate whether children maintain a single word-object hypothesis -- and revise it if falsified by later information -- or whether children establish a network of word-object associations whose relative strengths are…

Our ability to perceive our own and other people's bodies is critical to the success of social interactions. Research has shown that adults have a distorted perception of their own body and those of other adults. However, these studies ask perceivers to estimate for adults with a similar bodily make-up. This study explored the developmental…

Children with autism spectrum disorder (ASD) often demonstrate difficulty communicating with others, and this may impact the extent to which they can engage in language during play. Previous researchers have used interventions to increase commenting during play with caregivers, siblings, and adult play partners. In these previous studies,…

The shape bias, a preference for mapping new word labels onto the shape rather than the color or texture of referents, has been postulated as a word-learning mechanism. Previous research has shown deficits in the shape bias in children with autism even though they acquire sizeable lexicons. While previous explanations have suggested the atypical…

Purpose: The purposes of this study were (a) to introduce "language access profiles" as a viable alternative construct to "communication mode" for describing experience with language input during early childhood for deaf and hard-of-hearing (DHH) children; (b) to describe the development of a new tool for measuring DHH…

Purpose: This study examined toddlers' processing of mispronunciations based on their frequency of occurrence in child speech and the speaker who produced them. Method: One hundred twenty 22-month-olds were assigned to 1 of 4 conditions. Using the intermodal preferential looking paradigm, toddlers were shown visual displays containing 1 familiar…

A recent study by Ponari, Norbury, and Vigliocco (2018), showed that emotional valence (i.e. whether a word evokes positive, negative, or no affect) predicts age-of-acquisition ratings and that up to the age of 8-9, children know abstract emotional words better than neutral ones. On the basis of these findings, emotional valence has been argued to…

The goal of this study was to determine if typically developing children could form grammatical categories from distributional information alone. Twenty-seven children aged six to nine listened to an artifcial grammar which contained strategic gaps in its distribution. At test, we compared how children rated novel sentences that ft the grammar to…
