We studied English-learning children's ability to learn the meanings of novel words from sentences containing truth-functional negation (Exp1) and to use the semantics of negation to inform word meaning (Exp2). In Exp1, 22-month-olds (n = 21) heard dialogues introducing a novel verb in either negative-transitive "("Mary didn't blick the…

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…

Language, as a tool for people's daily communication, has no gender bias itself. With the development of society, the language has changed correspondingly. Language serve as the mirror of society, inevitably reflecting people's minds or ideology as well as the culture and social conditions of a society. While in English, as the mother tongue of…

Many studies have addressed the question of the relative dominance of nouns over verbs in the productive vocabularies of children in the second year of life. Surprisingly, cross-class (noun-to-verb and verb-to-noun) relations between these two lexical categories have seldom been investigated. The present longitudinal study employed observational…

The purpose of this work is to determine how widely and in which semantic and morphologic categories, word associations are used by children. There is no study about word associations children use in the acquisition of Turkish as their mother tongue. Participants of the current research consisted of a total of 90 kids between 4.0 and 6.0 years of…

Well-developed lexical representations are important for reading comprehension, but there have been no prior attempts to track growth in the depth of knowledge of particular words. This article examines increases in depth of vocabulary knowledge in 4-5-year-old preschool students (n = 240) who participated in a vocabulary intervention that taught…

The purpose of this study was to understand vocabulary characteristics in toddlers who are late talkers (LT) as compared with age-matched (AM) and vocabulary-matched (VM) peers. The semantic categories (e.g., animals, foods, toys) and the percentage of nouns, verbs, and closed-class words in the vocabularies of 36 toddlers (12 LT, 12 AM, 12 VM)…

For sixty-seven children with ASD (age 1;6 to 5;11), mean Total Vocabulary score on the Language Development Survey (LDS) was 65.3 words; twenty-two children had no reported words; and twenty-one children had 1-49 words. When matched for vocabulary size, children with ASD and children in the LDS normative sample did not differ in semantic category…

CHALLENGE is generally perceived as a negative word synonymous with "dispute," "defy," "confrontation," and "contest." However, when resorting to dictionary definitions, CHALLENGE has unexpectedly been found to possess positive senses such as "stimulating" and "arousing competitive…

Cognates have served as a useful tool for investigating the bilingual lexicon in many studies, but very little research has been carried out on different types of cognates, specifically, partial cognates and their role in cross-linguistic effect. The present study examines cognate effect in the speech production and acceptability judgment of two…

Most vocabulary growth during the school-age years occurs incidentally. However, little is understood about the influence of language skills on word knowledge growth during reading. Using a pretest-posttest quasi-experimental design, we examined incidental word learning through reading, considering the presence/absence of supportive context and…

The present study aimed to clarify the spatiotemporal characteristics of memory processing for abstract and concrete words. Neuromagnetic responses to memory encoding and recognition tasks of abstract and concrete nouns were obtained in 18 healthy adults using a whole-head neuromagnetometer. During memory encoding, abstract words elicited larger…

We present two eye-tracking experiments that investigate lexical frequency and semantic context constraints in spoken-word recognition in German. In both experiments, the pivotal words were pairs of nouns overlapping at onset but varying in lexical frequency. In Experiment 1, German listeners showed an expected frequency bias towards…

Investigations into early vocabulary development, including the timing of the acquisition of nouns, verbs and closed-class words, have produced conflicting results, both within and across languages. Studying vocabulary development in Irish can contribute to this area, as it has potentially informative features such as a VSO word order, and…

Word learning is a lifelong activity constrained by cognitive biases that people possess at particular points in development. Age of acquisition (AoA) is a psycholinguistic variable that may prove useful toward gauging the relative weighting of different phonological, semantic, and morphological factors at different phases of language acquisition…
