Familiar Object Salience Affects Novel Word Learning

Abstract: Children use the presence of familiar objects with known names to identify the correct referents of novel words. In natural environments, objects vary widely in salience. The presence of familiar objects may sometimes hinder rather than help word learning. To test this hypothesis, 3-year-olds (N = 36) were shown novel objects paired with familiar objects that varied in their visual salience. When the novel objects were labeled, children were slower and less accurate at fixating them in the presence of highly salient familiar objects than in the presence of less salient familiar objects. They were also less successful in retaining these word-referent pairings. While familiar objects may facilitate novel word learning in ambiguous situations, the properties of familiar objects matter.

Comparing Automatic Eye Tracking and Manual Gaze Coding Methods in Young Children with Autism Spectrum Disorder.

Abstract: Eye-gaze methods offer numerous advantages for studying cognitive processes in children with autism spectrum disorder (ASD), but data loss may threaten the validity and generalizability of results. Some eye-gaze systems may be more vulnerable to data loss than others, but to our knowledge, this issue has not been empirically investigated. In the current study, we asked whether automatic eye-tracking and manual gaze coding produce different rates of data loss or different results in a group of 51 toddlers with ASD. Data from both systems were gathered (from the same children) simultaneously, during the same experimental sessions. As predicted, manual gaze coding produced significantly less data loss than automatic eye tracking, as indicated by the number of usable trials and the proportion of looks to the images per trial. In addition, automatic eye-tracking and manual gaze coding produced different patterns of results, suggesting that the eye-gaze system used to address a particular research question could alter a study's findings and the scientific conclusions that follow. It is our hope that the information from this and future methodological studies will help researchers to select the eye-gaze measurement system that best fits their research questions and target population, as well as help consumers of autism research to interpret the findings from studies that utilize eye-gaze methods with children with ASD. Autism Res 2020, 13: 271-283. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: The current study found that automatic eye-tracking and manual gaze coding produced different rates of data loss and different overall patterns of results in young children with ASD. These findings show that the choice of eye-gaze system may impact the findings of a study-important information for both researchers and consumers of autism research.

Specificity of Phonological Representations for Children with Autism Spectrum Disorder

Abstract: This study investigated whether children with autism spectrum disorder (ASD) are sensitive to mispronunciations of familiar words and compared their sensitivity to children with typical-development. Sixty-four toddlers with ASD and 31 younger, typical controls participated in a looking-while-listening task that measured their accuracy in fixating the correct object when it was labelled with a correct pronunciation versus mispronunciation. A cognitive style that prioritizes processing local, rather than global features, as claimed by the weak central coherence theory, predicts that children with ASD should be more sensitive to mispronunciations than typical controls. The results, however, reveal no differences in the effect of mispronunciations on lexical processing between groups, even when matched for receptive language or non-verbal cognitive skills.

Roses Are Red, Socks Are Blue: Switching Dimensions Disrupts Young Children's Language Comprehension.

Abstract: Language is used to identify objects in many different ways. An apple can be identified using its name, color, and other attributes. Skilled language comprehension requires listeners to flexibly shift between different dimensions. We asked whether this shifting would be difficult for 3-year-olds, who have relatively immature executive function skills and struggle to switch between dimensions in card sorting tasks. In the current experiment, children first heard a series of sentences identifying objects using a single dimension (either names or colors). In the second half of the experiment, the labeling dimension was switched. Children were significantly less accurate in fixating the correct object following the dimensional switch. This disruption, however, was temporary; recognition accuracy recovered with increased exposure to the new labeling dimension. These findings provide the first evidence that children’s difficulty in shifting between dimensions impacts their ability to comprehend speech. This limitation may affect children’s ability to form rich, multi-dimensional representations when learning new words.

How Children Learn the Meanings of Words

Abstract: How Children Learn the Meanings of Words by Paul Bloom. Cambridge, Massachusetts: MIT Press, 2000, xii+300 pp. Reviewed by Masahiko Minami San Francisco State University How do children learn the meanings of words? In his new book, Paul Bloom examines a variety of issues associated with children's word learning, a process intricately connected with other aspects of language acquisition. Bloom claims that children learn words via cognitive abilities that already exist for other pur- poses, such as the ability to infer others' intentions, the ability to acquire concepts, and an appreciation of syntactic In structure. Bloom's book provides a series of el- egant and convincing arguments concerning how children learn words. briefly Chapter First Words, Bloom lays out the plan for the book and describes issues surrounding the overall topic. In Chapter 2 the author explores fast mapping, in which children make a quick guess about a word's denotation on the basis of limited experience. Chapter 3, Theory of Mind, deals with a wide range of topics, including the listener's ability to determine the references made by his or her interlocutor's choice of words; here also, Bloom investigates children's appreciation of the mental states of others, through which children acquire lexical items (and syntax as well) by means of associative acquire are nouns, learning. Because the majority of words that children initially Bloom gives special treatment to nouns and pronouns: Common nouns are discussed in Chapter 4, and pronouns and proper names are dealt with in Chapter 5. In Chapter 6, Concepts and Categories, Bloom extends his analysis to the conceptual foundations of word learning. In Chapter Naming Representations, he discusses a case study important to any theory of concepts and naming visual representations. From here, Bloom moves to other parts of speech: In Chapter 8, Learning Words through Linguistic Context, he offers an account of how chil- dren learn verbs and adjectives, as the development of syntactic abilities cannot be dissociated from the development of lexical abilities. Chapter 9 deals with learn the how we numbers and Chapter 10 with how the words we learn affect our mental life. In Chapter 11, Final Words, Bloom provides a brief summary and some general remarks. Throughout the book, the author weaves in ideas pro- posed by such linguists, psychologists, and philosophers as B. F. Skinner, Noam Chomsky, and Jean Piaget, who, through different lenses, have closely observed words for and analyzed how human beings develop and around them. issue long relevant to how they conceptualize the world As with most language acquisition texts, Bloom makes early reference to an human development: the nature/nurture debate.

Prediction during language processing is a piece of cake – but only for skilled producers

Abstract: 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 in a visual scene (a cake) soon after they hear the semantically constraining verb eats and prior to hearing the word cake. Importantly, children’s prediction skills were significantly correlated with their productive vocabulary size—skilled producers (i.e., children with large production vocabularies) showed evidence of predicting upcoming linguistic input, while low producers did not. Furthermore, we found that children’s prediction ability is tied specifically to their production skills and not to their comprehension skills. Prediction is really a piece of cake, but only for skilled producers.

Behavioural methods for investigating morphological and syntactic processing in children. Developmental psycholinguistics: On-line methods in children's language processing.

Abstract: While most first language acquisition research to date has focused on the development of children's linguistic competence, a number of research teams have also investigated the mechanisms children employ to process sentence-level and word-level information in real time, by applying experimental techniques familiar from the adult processing literature to children. This chapter presents an overview of different kinds of behavioral tasks for investigating both morphological and syntactic processing in children focusing on three techniques that we have explored in our own research on children's on-line language processing: self-paced listening, cross-modal priming, and speeded production.
