Illiteracy remains a world-wide problem not only for children but also for adults. Phonological processing has been defined as a crucial factor for the acquisition of written language, which usually occurs in childhood. However, it is unclear to what extent phonological processing is necessary in order for adults to acquire written language skills. We tested 47 illiterate adults before and afte...

The phonological loop system of Baddeley and colleagues' Working Memory model is a major accomplishment of the modern era of cognitive psychology. It was one of the first information processing models to make an explicit attempt to accommodate both traditional behavioral data and the results of neuropsychological case studies in an integrated theoretical framework. In the early and middle 1990s...

The performance ofm...

Working memory has been consistently associated with mathematics achievement, although the etiology of these relations remains poorly understood. The present study examined the genetic and environmental underpinnings of math story problem solving, timed calculation, and untimed calculation alongside working memory components in 12-year-old monozygotic (n = 105) and same-sex dizygotic (n = 143) ...

Phonological short-term memory capacity is generally measured with a word span task or a digit span task. Another way to measure it is to use a nonword repetition task. Gathercole and Adams (1993) claimed that this procedure can be used with children as young as two-years old. It seems that in normally developing children the quality of nonword repetition is influenced both by the nonwords leng...

The aim of our study was to analyze the functioning of various aspects of memory in adults with developmental dys lexia, as compared to adults without developmental dyslexia. Our research involved a total of 180 adults, mostly students and university graduates from the Tri-City metropolitan region in north central Poland. The criterion group consisted of 93 adults with developmental dyslexia, w...

Recent evidence suggests that phonological short-term memory (STM) tasks are influenced by both lexical and sublexical factors inherent in the selection and construction of the stimuli to be recalled. This study examined whether long-term memory (LTM) influences STM at a sublexical level by investigating whether the frequency with which one-syllable nonwords occur in polysyllabic words influenc...

This study investigates whether working memory skills of children are related to teacher ratings of their progress towards learning goals at the timeof school entry, at 4 or5 yearsof age. A sample of 194 children was tested on measures of working memory, phonological awareness, and non-verbal ability, in addition to the school-based baseline assessments in the areas of reading, writing, mathema...

In order to explore verbal-nonverbal integration, we investigated the influence of cognitive and linguistic ability on gaze behavior during spoken language conversation between children with mild-to-moderate hearing impairment (HI) and normal-hearing (NH) peers. Ten HI-NH and 10 NH-NH dyads performed a referential communication task requiring description of faces. During task performance, eye m...

Patients with Alzheimer's disease (AD) have been found to exhibit lower levels of false recognition of semantic associates compared with healthy older adults. Because these patients may show impaired performance of episodic and semantic memory tasks, this finding could be explained by deficits in episodic memory, semantic memory, or both. The authors adapted a paradigm for comparison of semanti...
