Deficits in verbal long-term memory and learning in children with poor phonological short-term memory skills.
Possible links between phonological short-term memory and both longer term memory and learning in 8-year-old children were investigated in this study. Performance on a range of tests of long-term memory and learning was compared for a group of 16 children with poor phonological short-term memory skills and a comparison group of children of the same age with matched nonverbal reasoning abilities...
متن کاملSpeech timing and verbal short-term memory: Evidence for contrasting deficits in Down syndrome and Williams syndrome
This study explored the degree of verbal short-term memory deficit among individuals with Down syndrome and Williams syndrome, and the extent to which any such impairment could be accounted for by a relative slowing of rehearsal and output processes. Measures of serial recall and detailed assessments of speeded articulation for short and long words were assessed among these two populations, and...
متن کاملDown syndrome and the phonological loop: the evidence for, and importance of, a specific verbal short-term memory deficit.
Individuals with Down syndrome are thought to perform poorly on tests of verbal short-term memory, such as measures of word span or digit span. This review critically examines the evidence for a specific deficit in verbal short-term memory in Down syndrome, and outlines a range of possible explanations for such a deficit. The potential implications of a verbal short-term memory impairment for b...
متن کاملAn investigation of verbal short-term memory and phonological processing in four children with Williams syndrome.
Abstract Although phonological processing is generally considered to be a proficiency in Williams syndrome (WS), there are very few studies which have extensively explored phonological processing abilities in WS. In this study, we re-assessed phonological processing in WS by exploring verbal STM and phonological awareness abilities in 4 children with WS (CA: 10-12 years) and two control groups,...
متن کاملSemantic Networks and Order Recall in Verbal Short-Term Memory
In a recent paper, Acheson, MacDonald, and Postle (2011) made an important but controversial suggestion: They hypothesised that a) semantic information has an effect on order information in short-term memory (STM) and b) that order recall in STM is based on the level of activation of items within the relevant long-term memory (LTM) network. However, verbal STM research typically has led to the ...
