We evaluated a simple computational model of productive vocabulary acquisition, applied to simulating two case studies of 7-year-old children with developmental word-finding difficulties across four core behavioural tasks. Developmental models were created, which captured the deficits of each child. In order to predict the effects of intervention, we exposed the computational models to simulate...

In the study influences on the productive vocabulary are examined regarding 16 month old children with, or with no siblings at home (n = 121). A parental report form, CDI, was used as instrument.Hypotheses regarding effects of different interaction environments were derived from the literature, and significant effects on the productive vocabulary were found; The first effect was that the produc...

Vocabulary acquisition is one of the most challenging obstacles language learners must overcome. This is especially true for students wishing to study in overseas universities, where comprehension of academic texts is required. This dissertation evaluates the vocabulary teaching component of an intensive English teaching programme for students intending to enter universities in the U.S. It firs...

a growing body of research has indicated that students of esl/efl are reticent and unwilling to be engaged in oral activities in english lessons. communicative language ability includes speaking ability, so vocabulary knowledge plays an integral role in speaking a language. however, there have been few studies examining the degree to which vocabulary knowledge affects speaking ability. the pres...

This study investigated the receptive and productive vocabulary command of learners based on their willingness to communicate (WTC) and critical thinking skill. The study also aimed to compare gifted and non-gifted learners in terms of the above-mentioned variables. To this end, 112 gifted and non-gifted Iranian EFL learners were picked out and given four instruments (W...

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 semantical...

This paper describes phonological development in children with Down syndrome paying particular attention to underlying deficits and intervention strategies. The first section provides an overview of factors believed to influence phonological development in this population. The second section describes four aspects of Down syndrome phonology: (1) the prelinguistic stage; (2) the transition to sp...

This paper reports evidence from a longitudinal study in which children's attention to shape in a laboratory task of artificial noun learning was correlated with a rate shift in noun acquisitions. Eight children were tested in the laboratory at 3-week intervals beginning when they had less than 25 nouns in their productive vocabulary (M age=17 months). Children were presented with a novel word ...
