The recognition of familiar words was evaluated in 20-month-old children raised in a rhotic accent environment to parents that had either rhotic or non-rhotic accents. Using an Intermodal Preferential Looking task children were presented with familiar objects (e.g. "bird") named in their rhotic or non-rhotic form. Children were only able to…

This dissertation studies how people describe emotions with language and how computers can simulate this descriptive behavior. Although many non-human animals can express their current emotions as social signals, only humans can communicate about emotions symbolically. This symbolic communication of emotion allows us to talk about emotions that we…

Pronouns seem to be acquired in an asymmetrical way, where children confuse the meaning of pronouns with reflexives up to the age of six, but not vice versa. Children's production of the same referential expressions is appropriate at the age of four. However, response-based tasks, the usual means to investigate child language comprehension, are…

Purpose: In this study, the authors used cued shadowing to examine children's phonological word-form representations by studying the effects of onset and rhyme primes on lexical access. Method: Twenty-five preschoolers with specific language impairment (SLI; hereafter known as the SLI group), 24 age- and gender-matched children (AM group), and 20…

Using online measures of familiar word recognition in the looking-while-listening procedure, this prospective longitudinal study revealed robust links between processing efficiency and vocabulary growth from 18 to 30 months in children classified as typically developing (n = 46) and as "late talkers" (n = 36) at 18 months. Those late talkers who…

This dissertation tests a new account of rapid word learning and vocabulary growth that these processes develop as the result of attentional biases to the features of a category that are relevant to labeling/categorization, built as the result of word-learning experience within each category. Study 1 demonstrated that children's vocabulary size…

Rules, and exceptions to such rules, are ubiquitous in many domains, including language. Here we used simple artificial grammars to investigate the influence of 2 factors on the acquisition of rules and their exceptions, namely type frequency (the relative numbers of different exceptions to different regular items) and token frequency (the number…

There is much debate over the degree to which language learning is governed by innate language-specific biases, or acquired through cognition-general principles. Here we examine the probabilistic language acquisition hypothesis on three levels: We outline a novel theoretical result showing that it is possible to learn the exact "generative model"…

A persistent mystery in language acquisition is how speakers are able to learn seemingly arbitrary distributional restrictions. This article investigates one such case: the fact that speakers resist using certain adjectives prenominally (e.g. ??"the asleep man"). Experiment 1 indicates that speakers tentatively generalize or "categorize" the…

This Special Issue on Morphological Processing is based on the sixth MOrphological PROcessing Conference (MOPROC), which was kept in June 2009 in Turku, Finland. The issue contains 13 articles by leading scholars in the field of morphological processing. These articles investigate the role morphemes play in language comprehension, production and…

Healthy adults can identify spoken words at a remarkable speed, by incrementally analyzing word-onset information. It is currently unknown how this adult-level speed of spoken-word processing emerges during children's native-language acquisition. In a picture-word mismatch paradigm, we manipulated the semantic congruency between picture contexts…

Idiomatic expressions pose substantial learning difficulties for learners across languages and tend to be acquired later in the course of language development both in L1 and L2. A number of factors have been identified as contributing to this difficulty. However, cross-linguistic studies on figurative language acquisition are still rare. The…

Function words support many aspects of language acquisition. This study investigated whether toddlers understand the number feature of determiners and use it for noun comprehension. French offers an ideal "test case" as number is phonetically marked in determiners but not in nouns. Twenty French-learning 24-month-olds completed a split-screen…

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 &…

Are there individual differences in children's prediction of upcoming linguistic input and what do these differences reflect? Using a variant of the preferential looking paradigm (Golinkoff, Hirsh-Pasek, Cauley, & Gordon, 1987), we found that, upon hearing a sentence like, "The boy eats a big cake," 2-year-olds fixate edible objects…
