UNLABELLED Two types of serial word recall tasks (full verbal recall and probed recall) were administered to 11 children with language impairment and 22 language-normal children matched for productive language or chronological age. The methods were designed to take into account age-related differences in the use of subvocal rehearsal, as measured by the word length effect. The word length effec...

SWETWOL is implemented in the framework of Koskenniemi’s (1983) two-level model. It contains a 48,000 item lexicon and a full inflectional description. Special attention was paid to the design of a computational analysis of productive Swedish compounds. Recall (coverage) and precision of SWETWOL meet high standards. SWETWOL has been extensively tested on various types of texts.

This research examines changes in word retrieval and naming during a developmental period in which there is a substantial increase in productive vocabulary. That increase generally occurs when children have between 50 to 150 words in productive vocabulary. We examined children's naming errors in two studies for what these errors could tell us about the emerging lexicon. The method we used for e...

A coloured male, aged i6 years, whose occupation was a metal grinder, was first seen in the Eye Out-Patients' Department at Groote Schuur Hospital on July I6, I97I. He gave a 3-day history of a sudden onset of pain in the left eye followed by swelling of the lids and proptosis. He could not recall sustaining trauma to the left eye nor could he recall being injured by a foreign body entering the...

Cognitive function of patients on monotherapy specific for their epileptic syndrome has been studied infrequently. We evaluated 7 patients with symptomatic localised epilepsies (SEL) on phenytoin aged 30 +/- 12 (mean +/- standard deviation) years, 8 with idiopathic generalised epilepsies on sodium valproate aged 18 +/- 4 years, 16 with SEL on carbamazepine aged 28 +/- 11 years, and 35 healthy c...

This quasi-experimental study investigated the effect of bottom-up and top-down instructional approaches on English as a foreign language (EFL) vocabulary recall and retention. To this end, 44 high school students from two intact classes were assigned to bottom-up (n = 21) and top-down (n = 23) groups. The participants were exposed to 20 hours of explicit vocabulary instruction during 10 weeks ...

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...
