Working memory retains visual details despite distractions
January 20, 2006The ability to retain memory about the details of a natural scene is unaffected by the distraction of another activity and this information is retained in "working memory" according to a study recently published in Journal of Vision, an online, free access publication of the Association for Research in Vision and Ophthalmology (ARVO). These results reinforce the notion that humans maintain useful information about previous fixations in long-term working memory rather than the limited capacity of visual short-term memory (VSTM).
Memory has traditionally been divided into VSTM and long-term memory (LTM). VSTM usually involves the retention of about four objects at a time. This is followed by either information loss or the transfer of this information into LTM. This study provides further evidence that an intermediary "working memory" better describes the nature of information retained while engaged in a particular task.
In the study conducted by Oxford Brookes University Professor David Melcher, participants were asked to view a photograph of a natural scene for 10 seconds. Following the initial viewing, they were asked to silently read a paragraph for 60 seconds, repeating if necessary, or view an image with five colored square for 60 seconds. The participants were then asked questions about the first scene they had viewed. The results show that the addition of the reading task had no measurable influence on the average performance for either color, shape or location questions compared to other trials which involved just a 10-second delay between the viewing and the testing.
According to Melcher, "These results provide further evidence that visual scenes are special and that memory for real scenes involves a system with different properties than that used for words or simple shapes. We are currently examining how this memory system develops in children, how it is affected by aging and how it interacts with attention and disorders of attention."

Iowa State study finds high volume video gamers have more difficulty staying attentive
Parents have long lectured their children about the mind-numbing effects of playing video games all day. And a new Iowa State University study has found that high volume action video game players -- those who play around 40 hours per week -- actually had more difficulty keeping focused on tasks requiring longer, more proactive attention than those who played video games less than a couple of hours a week.

The Overflowing Brain: Information Overload and the Limits of Working Memory by Torkel Klingberg (Author) As the pace of technological change accelerates, we are increasingly experiencing a state of information overload. Statistics show that we are interrupted every three minutes during the course of the work day. Multitasking between email, cell-phone, text messages, and four or five websites while listening to an iPod forces the brain to process more and more informaton at greater and greater speeds. And yet the human brain has hardly changed in the last 40,000 years. Are all these high-tech advances overtaxing our Stone Age brains or is the constant flood of information good for us, giving our brains the daily exercise they seem to crave? In The Overflowing Brain, cognitive scientist Torkel Klingberg takes us on a journey into the limits and possibilities of the brain. He... |

Working Memory, Thought, and Action (Oxford Psychology Series) by Alan Baddeley (Author) The first edition of Working Memory was published in 1986 and was both widely cited and highly influential. The follow-up to this classic book has two aims - to discuss the developments that have occurred within the multicomponent model, since the publication of Working Memory, and secondly, to place the concept of multicomponent working memory in a broader context. The updating section of the book comprises two chapters each on the phonological loop, the visuo-spatial sketchpad, the central executive and the episodic buffer, with further chapters on the relevance to working memory of studies of the recency effect, of work based on individual differences, and of neuroimaging research. The broader implications of the concept of working memory are discussed in chapters on social... |

Working Memory Capacity (Essays in Cognitive Psychology) by Nelson Cowan (Author) The idea of one's memory "filling up" is a humorous misconception of how memory in general is thought to work; it is actually has no capacity limit. However, the idea of a "full brain" makes more sense with reference to working memory, which is the limited amount of information a person can hold temporarily in an especially accessible form for use in the completion of almost any challenging cognitive task. This groundbreaking book explains the evidence supporting Cowan's theoretical proposal about working memory capacity, and compares it to competing perspectives. Cognitive psychologists profoundly disagree on how working memory is limited: whether by the number of units that can be retained (and, if so, what kind of units and how many?), the types of interfering material, the... |

Working Memory and Education (Educational Psychology) by Susan J. Pickering (Editor), Gary D. Phye (Editor) Psychologists have been trying to understand the factors that underpin children's success and failure in different educational domains for many years. One psychological function that has been found to play an important role in educational achievement is 'working memory', the processes involved in the temporary maintenance and manipulation of information. This book provides the reader with an up-to-date review of the research that has identified how working memory relates to academic attainment in: reading, reading comprehension, arithmetic and writing, as well as looking at how children with difficulties relating to hearing impairment and attention deficits differ in terms of their working memory. Other chapters focus on how working memory is called upon in classroom settings, how working... |

Variation in Working Memory by Andrew Conway (Editor), Chris Jarrold (Editor), Michael Kane (Editor), Akira Miyake (Editor), John Towse (Editor) Working memory--the ability to keep important information in mind while comprehending, thinking, and acting--varies considerably from person to person and changes dramatically during each person's life. Understanding such individual and developmental differences is crucial because working memory is a major contributor to general intellectual functioning. This volume offers a state-of-the-art, integrative, and comprehensive approach to understanding variation in working memory by presenting explicit, detailed comparisons of the leading theories. It incorporates views from the different research groups that operate on each side of the Atlantic, and covers working-memory research on a wide variety of populations, including healthy adults, children with and without learning difficulties,... |
