Designing appropriate materials and activities to enhance vocabulary learning is one of the primary goals of language courses. Among the claims about efficient pedagogical tasks is the Involvement Load Hypothesis (Laufer & Hulstijn, 2001) according to which vocabulary development is contingent on the amount of cognitive process a task involves. Building on the previous research on this hypothes...

This longitudinal ERP study investigated changes in children's ability to map novel words to novel objects during the dynamic period of vocabulary growth between 20 and 24 months. During this four-month period the children on average tripled their productive vocabulary, an increase which was coupled with changes in the N400 effect to pseudoword-referent associations. Moreover, productive vocabu...

The purpose of the present study was to provide empirical support for the construct of the involvement load hypothesis (ILH ) in an EFL context. To fulfill the purpose of the study, 4 intact groups consisting of 126 intermediate-level students participated in this experiment. In order to ensure that the participants were at the same level of English language proficiency, the Nelson test was adm...

To investigate the effects of different glossing conventions on vocabulary recognition and recall, 158 participants were given a pre-test to make sure that they did not have any prior knowledge of the target words. Reading passages with four different glossing conventions (interlinear, marginal, pre-text, and post-text) were given to eight groups. Four groups received interlingual glosses and f...

Although it is well documented that children undergo a productive vocabulary spurt late in the second year, it is unclear whether this development is accompanied by equally significant advances in receptive word processing. In the present study, we tested an electrophysiological procedure for assessing receptive word learning in young children, and the impact of productive vocabulary size for p...

The  present  study  investigated  the  effects  of  three  methods  of  vocabulary  presentation,  i.e., picture,  song,  and  the  keyword  method  on  Iranian  EFL  learners'  vocabulary  recognition  and production.  The  participants  were  102  Iranian  lower-intermediate  EFL  learners  in  Zaban  Sara English language institute in Kermanshah. To make sure that they had no previous knowl...

Meara’s new volume primarily focuses on how word association data can be used in second language vocabulary acquisition research, particularly in the areas of the development of vocabulary depth, productive vocabulary skills and lexical organization in second language (L2) speakers. His book also serves as a concise summation of research to date involving word associations and second language v...
