OBJECTIVE This study tested the hypothesis that impaired working memory is a core deficit underlying multiple neuropsychological deficits in schizophrenia patients. METHOD The subjects were 27 men with stable chronic schizophrenia treated with atypical antipsychotics and 38 normal participants. They were assessed with a battery of neuropsychological tests. Verbal working memory was measured w...

This study describes  working  memory and developing and validating of an  L1 Persian reading span test for the measurement of working  memory of L1 Persian EFL learners. The test, which included  64  Persian  sentences,  was  developed  based  on  Daneman  and Carpenter’s (1980) reading  span  test.  The  shortcomings  of  the  test  were  identified  and  removed  over  three  pilot studies  ...

Working-memory capacity is conceptually differentiated according to functions and contents. The resulting two-faceted structure parallels the structure of intellectual abilities in the Berlin Intelligence Structure Model (BIS) [Diagnostica 28 (1982) 195.]. A battery of 17 working-memory tasks, chosen to represent the proposed facet structure of working memory, was administered together with a t...

The current study examined memory and executive functioning in a sample of children who were hospital ized in a neonatal intensive care unit (NICU) after birth. Thirty-two children born prematurely and/or with medical complications (NICU children) and 25 control children born at term were assessed with the Cambridge Neuropsychological Testing Automated Battery (CANTAB), a multi-dimensional comp...

Background: Learning disabilities (LDs) are diagnosed in children impaired in the academic skills of reading, writing, and/or mathematics. Children with LDs usually exhibit a slower resting-state electroencephalogram (EEG), corresponding to a neurodevelopmental lag. The present study aimed to investigate the effectiveness of neurofeedback treatment on working memory and processing speed among g...

although investigating the factors that influence test scores is important, a majority of stakeholders show a paucity of attention towards individual learner differences due to having large classes of l2 learners. this study sought to explore the possible effect of working memory and cognitive style on l2 learners’ metaphorical test performance. the study was conducted in 2 phases. the first ph...

PURPOSE Controversy exists regarding the relation between visual memory and academic achievement. METHODS A masked investigation of the relation between visual memory and academics was performed in 155 second-through fourth-grade children (mean age = 8.83 years). Visual memory ability was assessed with the Test of Visual Perceptual Skills visual memory subtest. The school administered the Oti...

Several recent studies have suggested that deaf children perform more poorly on working memory tasks compared to hearing children, but these studies have not been able to determine whether this poorer performance arises directly from deafness itself or from deaf children's reduced language exposure. The issue remains unresolved because findings come mostly from (1) tasks that are verbal as oppo...

OBJECTIVE Prospective memory (PM) is the ability to remember to carry out an intended action. Working memory is the ability to store information in mind while processing potentially distracting information. The few previous studies of PM in autism spectrum disorder (ASD) have yielded inconsistent findings. Studies of working memory ability in ASD have suggested a selective impairment of "visual...
