Purpose: We examined the neurocognitive bases of lexical morphology in children of varied reading abilities to understand the role of meaning-based skills in learning to read with dyslexia. Method: Children completed auditory morphological and phonological awareness tasks during functional near-infrared spectroscopy neuroimaging. We first examined…

Recent years have seen a flourishing of Natural Language Processing models that can mimic many aspects of human language fluency. These models harness a simple, decades-old idea: It is possible to learn a lot about word meanings just from exposure to language, because words similar in meaning are used in language in similar ways. The successes of…

Accumulating information and knowledge is a major task of development. A common assumption is that we build our storehouse of world knowledge, our semantic memory, through direct experience. Although direct experience is involved, to explain fully how we know all that we know, we also must consider processes that allow for integration of…

Despite receiving scant attention, the evolution of categorization in early childhood is of central importance, not only in clarifying the child's understanding of the world but in terms of refining cognitive organization and augmenting the development of semantic memory. In this review, we outline how categorization develops and is made manifest…

This study investigates the influence of semantic maturation on early lexical development by examining the impact of contextual diversity--known to influence semantic development--on word promotion from receptive to productive vocabularies (i.e., comprehension-expression gap). Study 1 compares the vocabularies of 3685 American-English-speaking…

Cognitive tasks are seldom evaluated on their ability to provide valid and reliable measurements of the construct they intend to measure. This scarcity of psychometric evaluations makes it challenging to evaluate replications of experimental effects and to relate performance in cognitive tasks to other constructs of interest. In developmental…

The present study investigates the relation between language environment and language delay in 63 British-English speaking children (19 typical talkers (TT), 22 late talkers (LT), and 22 late bloomers (LB) aged 13 to 18 months. Families audio recorded daily routines and marked the new words their child produced over a period of 6 months. To…

With development knowledge becomes organized according to semantic links, including early-developing associative (e.g., juicy-apple) and gradually developing taxonomic links (e.g., apple-pear). Word co-occurrence regularities may foster these links: Associative links may form from direct co-occurrence (e.g., juicy-apple), and taxonomic links from…

Organized semantic representations encoding across- and within-domain distinctions are a hallmark of mature cognition, and understanding how they change with experience and learning is a key endeavor in developmental science. Existing computational modeling studies provide a mechanistic framework for understanding how structured semantic…

Associative anaphora refers to a discourse operation that links a definite determiner phrase (DP) to an antecedent that acts as an indirect referent of the definite DP. For example, in the sequence 'I bought a laptop. The keyboard was black', the definite DP 'the keyboard' is linked to 'a laptop', meaning 'the keyboard of the laptop'. The…

Language is the basis of human communication and is the most important key to complete mental development and thinking. Therefore, children must learn to communicate using appropriate language. For this to happen, the development of language in the child must be understood as a biological process, complete with internal laws and with marked stages…

Toddlerhood is marked by advances in several lexico-semantic skills, including improvements in the size and structure of the lexicon and increased efficiency in lexical processing. This project seeks to delineate how early changes in vocabulary size and vocabulary structure support lexical processing (Experiment 1), and how these three skills…

Verbs are often uttered before the events they describe. By 2 years of age, toddlers can learn from such an encounter. Hearing a novel verb in transitive sentences (e.g. "The boy lorped the cat"), even with no visual referent present, they later map it to a causative meaning (e.g. "feed") (e.g. Yuan & Fisher, [Yuan, S.,…

Research on the early lexical-semantic system has described how toddlers organize word representations based on semantic and phonological features. This study is a longitudinal investigation of the development of this organization during infancy. Middle-high socioeconomic status Mexican toddlers (n = 28, 15 female) were presented with a…

This research aimed to explore the conversations between Aboriginal children and their educators in early childhood contexts. The research particularly focused on the relevance of these conversations for developing children's identity. Participants were Aboriginal and non-Aboriginal children and educators, who participated in conversations in…
