The nonword repetition (NWR) test has been shown to be a good predictor of children's vocabulary size. NWR performance has been explained using phonological working memory, which is seen as a critical component in the learning of new words. However, no detailed specification of the link between phonological working memory and long-term memory (LTM) has been proposed. In this paper, we present a...

The present thesis investigated cognitive ability in children with severe to profound hearing impairment who have received cochlear implants (CIs). The auditory stimulation from a cochlear implant early in life influences most cognitive functions as a consequence of the plasticity of the brain in the young child. It is important to understand the cognitive consequences of auditory stimulation f...

The aim of this study was to investigate the functional organisation of working memory and related cognitive abilities in young children. A sample of 633 children aged between 4 and 6 years were tested on measures of verbal short-term memory, complex memory span, sentence repetition, phonological awareness, and nonverbal ability. The measurement model that provided the best fit of the data inco...

OBJECTIVE To test the verbal subsystem of Baddeley's working memory model (the phonological loop) in patients with Parkinson's disease. METHODS Fifteen patients with idiopathic Parkinson's disease and 15 controls were tested with a span paradigm to assess the effects reflecting the functioning of the phonological loop: the phonological similarity effect (in verbal and visual presentation), an...

The working memory skills of children with four categories of special educational needs (SEN) were investigated: general learning difficulties, language problems, literacy problems, and attentional and behavioural problems. Children with general learning difficulties performed poorly on measures of all three components of the working memory model: the phonological loop, central executive, and t...

Ten cerebral palsied adolescents and young adults with complex communicative needs who use augmentative and alternative communication were studied. They were classified according to their high versus low working memory capacity and according to their high versus low phonological skills into two groups of participants. These groups were compared on their performance in reading tests –an orthogra...
