In successful communication, it is critical to have the ability to identify what a speaker is referring to from previously mentioned information. This ability requires the identification of the topic initially introduced by lexical forms and its continuity in discourse expressed by anaphora such as null and pronominal forms in the subsequent…

A large body of research suggests that spoken language processing is heavily influenced by social characteristics of the speaker, and conversely, that socio-cognitive processing is influenced by the language spoken by our interlocutors. However, little is known about the extent to which this interaction that is observed in adulthood has its roots…

Children who rapidly recognize and interpret familiar words typically have accelerated lexical growth, providing indirect evidence that lexical processing efficiency (LPE) is related to word-learning ability. Here we directly tested whether children with better LPE are better able to learn novel words. In Experiment 1, 17- and 30-month-olds were…

Word learning depends critically on the use of linguistic context to constrain the likely meanings of words. However, the mechanisms by which children infer word meaning from linguistic context are still poorly understood. In this study, we asked whether adults (n = 58) and 2- to 6-year-old children (n = 180) use discourse coherence relations…

Children's lexical processing speed at 18 to 25 months of age has been linked to concurrent and later language abilities. In the current study, we extend this finding to children aged 36 months. Children (N = 126) participated in a lexical processing task in which they viewed two static images on noun trials (e.g., an ear of corn and a hat), or…

The goal of the current study was to statistically evaluate the reliable scalability of a set of tasks designed to assess Theory of Mind (ToM) without language as a confounding variable. This tool might be useful to study ToM in populations where language is impaired or to study links between language and ToM. Low verbal versions of the ToM tasks…

To what extent do toddlers have shared vocabularies? We examined CDI data collected from 14,607 infants and toddlers in five countries and measured the amount of variability between individual lexicons during development for both comprehension and production. Early lexicons are highly overlapping. However, beyond 100 words, toddlers share more…

Across a diverse range of languages, children proceed through similar stages in their production of causal language: their initial verbs lack internal causal structure, followed by a period during which they produce causative overgeneralizations, indicating knowledge of a productive causative rule. We asked in this study whether a child not…

Structural priming is a useful laboratory-based technique for investigating how children respond to temporary changes in the distribution of structures in their input. In the current study we investigated whether increasing the number of object relative clauses (RCs) in German-speaking children's input changes their processing preferences for…

To explore how being at high risk for autism spectrum disorder (ASD), based on having an older sibling diagnosed with ASD, affects word comprehension and language processing speed, 18-, 24- and 36-month-old children, at high and low risk for ASD were tested in a cross-sectional study, on an eye gaze measure of receptive language that measured how…

Background: Understanding lexical abilities in infants and toddlers is important, yet no single tool can be used. Aims: To perform a validation of a new tool (known as the Picture Naming Game, or "PiNG") for assessing lexical comprehension and production in toddlers and to obtain developmental trends for Italian children. Methods &…

Two experiments investigated the development of fluency in interpreting adjective-noun phrases in 30- and 36-month-old English-learning children. Using online processing measures, children's gaze patterns were monitored as they heard the familiar adjective-noun phrases (e.g. "blue car") in visual contexts where the adjective was either informative…

The theory of syntactic bootstrapping proposes that children can use syntax to infer the meanings of words. This paper presents experimental evidence that children are also able to use word inflections to infer word reference. Twenty-four- and 30-month-olds were tested in a preferential looking experiment. Children were shown a pair of novel…

Methods used to assess children's speech perception and recognition in the clinical setting are out of step with current methods used to investigate these experimentally. Traditional methods of assessing speech discrimination, such as picture pointing, yield accuracy scores which may fail to detect subtle perceptual difficulties. This paper will…

Three studies examined children's learning of second labels for objects. Found that, at 24 months, subjects learned both labels equally well but had difficulty with the second label if a third word was introduced. Results suggest that, from six months on, mutual exclusivity helps children interpret novel words. (WP)
