Representations in working memory are a subset of the representations in long... Working memory is organized in two embedded levels... the chunks in working memory act as retrieval cues that point to the digits that they contain... with a capacity of only seven chunks our working memory would be full after a few sentences... Working memory is generally considered to have limited capacity... term or working memory to a number of chunks... has proposed that working memory has a capacity of about four chunks in young adults... Working memory capacity can be tested by a variety of tasks... have to qualify as a good measure of working memory capacity is a topic of ongoing research... that working memory capacity reflects the efficiency of executive functions... Others have argued that the capacity of working memory is better characterized as the ability to mentally form relations between elements... It has been suggested that working memory capacity can be measured as the capacity C of... The idea that working memory capacity is underlying general intelligence and can be measured in terms of bits has been... who demonstrated that working memory capacity depends on the number of chunks... Why is working memory capacity limited at all... Another hypothesis is that memory traces in working memory decay within a few seconds... Yet another idea is that representations held in working memory capacity interfere with each other... or other item in working memory is represented as a bundle of features... This theory assumes that representations in working memory decay unless they are refreshed... Recent studies suggest that working memory can be improved by training in ADHD patients through the Cogmed computerized program developed by... controlled study has found that a period of working memory training increases a range of cognitive abilities and increases IQ test scores... this study supports previous findings suggesting that working memory underlies general intelligence... measured brain activity related to working memory increased in the prefrontal cortex... further study has shown that training with a working memory task improves performance on a task of fluid intelligence in healthy young adults... s working memory ability may prove to be a reliable method for increasing a person... Working memory in the brain... Working memory in the brain... The first insights into the neuronal basis of working memory came from animal research... that the dorsolateral areas are responsible for spatial working memory and the ventrolateral areas for non... Brain imaging has also revealed that working memory functions are by far not limited to the PFC... shows areas of activation during working memory tasks scattered over a large part of the cortex... and for verbal and object working memory to recruit more left... The activation during verbal working memory tasks can be broken down into one component reflecting maintenance... There is an emerging consensus that most working memory tasks recruit a network of PFC and parietal areas... has shown that during a working memory task the connectivity between these areas increases... to argue that the role of PFC in working memory is in controlling attention... Most brain imaging studies of working memory have used recognition tasks such as delayed recognition of one or several stimuli... last two decades on where in the brain working memory functions are carried out... of certain neurons in the delay period of working memory tasks shows that the brain has a mechanism of keeping representations active without external input... there is no direct evidence that working memory uses this binding mechanism... speculated that synchronous firing of neurons involved in working memory oscillate with frequencies in the... There is now extensive evidence that working memory is linked to key learning outcomes in literacy and numeracy... This suggests that working memory impairments are associated with low learning outcomes and constitute a high risk factor for educational...
