Research with adults has shown that ambiguous spoken sentences are resolved efficiently, exploiting multiple cues--including referential context--to select the intended meaning. Paradoxically, children appear to be insensitive to referential cues when resolving ambiguous sentences, relying instead on statistical properties intrinsic to the language such as(More)
BACKGROUND Controversy over the measles, mumps, and rubella (MMR) vaccine has reduced uptake, raising concerns of a future disease epidemic. AIMS To explore parents' accounts of decision making relating to the MMR vaccine controversy, identifying uptake determinants and education needs. DESIGN OF STUDY Qualitative interviews analysed using the(More)
Although the acquisition of a novel word is apparently rapid, adult research suggests that integration of novel and existing knowledge (measured by engagement in lexical competition) requires sleep-associated consolidation. We present the first investigation of whether a similar time-course dissociation characterizes word learning across development.(More)
Research suggests that word learning is an extended process, with offline consolidation crucial for the strengthening of new lexical representations and their integration with existing lexical knowledge (as measured by engagement in lexical competition). This supports a dual memory systems account, in which new information is initially sparsely encoded(More)
An auditory sentence comprehension task investigated the extent to which the integration of contextual and structural cues was mediated by verbal memory span with 32 English-speaking six- to eight-year-old children. Spoken relative clause sentences were accompanied by visual context pictures which fully (depicting the actions described within the relative(More)
Previous studies using direct forms of vocabulary instruction have shown that newly learned words are integrated with existing lexical knowledge only after off-line consolidation (as measured by competition between new and existing words during spoken word recognition). However, the bulk of vocabulary acquisition during childhood occurs through incidental(More)
Recent studies of adults have found evidence for consolidation effects in the acquisition of novel words (Dumay & Gaskell, 2007), but little is known about whether such effects are found developmentally. In two experiments we familiarized children with novel nonwords (e.g., biscal) and tested their recognition and recall of these items. In Experiment 1(More)
Lexical competition that occurs as speech unfolds is a hallmark of adult oral language comprehension crucial to rapid incremental speech processing. This study used pause detection to examine whether lexical competition operates similarly at 7-8 years and tested variables that influence "online" lexical activity in adults. Children (n = 20) and adults (n =(More)
The inactivation dynamics of infectious haematopoietic necrosis virus (IHNV) by b-propiolactone (BPL), binary ethylenimine (BEI), formaldehyde or heat and the antigenic and immunogenic properties of the inactivated vaccines were evaluated. Chemical treatment of IHNV with 2.7 mm BPL, 1.5 mm BEI or 50 mm formaldehyde abolished virus infectivity within 48 h(More)
AIMS The present study aims to assess the extent to which attention to UK cigarette warnings is attributable to the graphic nature of the content. DESIGN A visual dot probe task was utilised, with the warnings serving as critical stimuli that were manipulated for the presence of graphic versus neutral image content, and the accompanying text caption.
