Working memory updating

A succession of photographs appears in the frame; the photos have different subject matter (animals, landscapes, colors etc.).

The client’s task is to decide whether the current photograph matches the one that was shown one, two or three places back (the number of places varies with the level). If it does not match, the red button must be pressed.

Working-memory maintenance involves frontoparietal regions and distributed representational areas, and can be based on persistent activity in reentrant loops, synchronous oscillations, or changes in synaptic strength.

Manipulation of content of working memory depends on the dorsofrontal cortex, and updating is realized by a frontostriatal ‘“gating” function.

Many diseases such as Alzheimer’s disease, Huntington's chorea, Parkinson's disease or attention deficit hyperactivity disorder are associated with impairments of working memory and consequent difficulties in coping with everyday tasks.

Recent scientific findings indicate that the capacity of working memory can be improved through regular training.

Access to society journal content varies across our titles.Yet, little is known about the constituent processes of WMU.We suggest that operations required in a typical WMU task can be decomposed into 3 major component processes: retrieval, transformation, and substitution.The client receives feedback on his performance at regular intervals (approx. The aim of this feedback is to maintain the client’s motivation at an optimal level.Working memory is of key importance in dealing with the demands of everyday life, especially when information that has been briefly presented must be retained and cognitively processed, or when a task needs to be performed or a goal achieved.
