How does one assess developmental change when the measures themselves change with development? Most developmental studies of word learning use either looking (infants) or pointing (preschoolers and older). With little empirical evidence of the relationship between the two measures, developmental change is difficult to assess. This paper analyzes…

In many domains, learners extract recurring units from continuous sequences. For example, in unknown languages, fluent speech is perceived as a continuous signal. Learners need to extract the underlying words from this continuous signal and then memorize them. One prominent candidate mechanism is statistical learning, whereby learners track how…

It is widely accepted that associative recognition can be supported by familiarity through integrating more than two stimuli into a unit, but there are still three unsolved questions: (1) how unitization affects recollection-based associative recognition; (2) whether it is necessary to match the level of unitization (LOU) between original and…

In this series of experiments, we tested the limits of young infants' word learning and generalization abilities in light of recent findings reporting sophisticated word learning abilities in the first year of life. Ten-month-old infants were trained with two word-object pairs and tested with either the same or different members of the…

This study investigates the relationship between depth of academic vocabulary knowledge and academic success among Saudi English-as-a-foreign-language university students. Fifty fourth-year university students majoring in English completed a vocabulary depth test, the Word Associates Test (WAT), based on the Academic Word List (AWL). Then,…

Language can alter our mental conceptions of space, time, and categories. While there is compelling evidence that thought can be shaped by syntactic, morphological, and lexical features of a language, less is known about the impact of phonology on thought. This dissertation uses novel objects (alien cartoon figures) and pseudoword names in three…

Background: We adopted a theoretical framework that the acquisition of a scientific concept comprises the development of connections among conceptual elements associated with a scientific term within a mental semantic network. Given this framework, the hypothesis that the surrounding words connected with a scientific term are relevant to the…

This study investigated the constructs underlying second language (L2) word association (WA) with regard to three dimensions of lexical competence--size, organization, and accessibility--and the lexical performance of speech. One-hundred and thirteen Japanese learners of English completed a computer-delivered oral WA task along with three…

When toddlers hear a novel word, they quickly and independently link it with a novel object rather than known-name objects. However, they are less proficient in retaining multiple novel words. Sleep and even short naps can enhance declarative memory in adults and children and this study investigates the effect of napping on children's memory for…

This study examined the simultaneous effects of L2 individual difference (ID) variables (aptitude, motivation, strategy use, language processing experience, and gender) on English as a foreign language (EFL) breadth and depth of L2 vocabulary knowledge of 492 Korean university-level learners. Independent variable measures included the: (1) Korean…

It is well documented in the cognitive literature that visual stimuli create strong memory connections (Shapiro & Waters, 2005). In L2 research, mnemonic devices have been found to be a relevant factor in the development of vocabulary learning (Sagarra & Alba, 2006). However, the extent to which visual cues are needed in the association of…

This study investigates the correlations between the three measures of written receptive vocabulary size and second language (L2) depth of vocabulary knowledge to find the most reliable test of vocabulary size. Moreover, the corresponding relationship is examined for the higher and lower word-frequency bands of the three tests to find whether the…

The purpose of the study was to investigate the relationship between Chinese MA students' depth of vocabulary knowledge, their use of L2 vocabulary learning strategy (VLS), and the types of L2 contact they encountered while studying abroad. 165 Chinese MA students from a British university participated in the study by filling out the questionnaire…

The present study was conducted in the context of learning English as a Foreign Language (EFL) with the purpose of assessing the roles of breadth and depth of vocabulary knowledge in academic listening comprehension. The Vocabulary Size Test (VST, Nation & Beglar, 2007) and the Word Associates Test (WAT, Read, 2004) were administered to…

In this study, word knowledge and its relation to text comprehension was examined with 50 Chinese- and 20 Korean-speaking second language (L2) learners and 40 first language (L1) speakers of Japanese. Breadth and depth of word knowledge were assessed by a word-definition matching test and a word-associates selection test, respectively. Text…
