The memory allows us to retain, organize and recall recorded information. As a rule, this is not a uniform construct but rather different subsystems which can exhibit specific dysfunctions as a result of brain damage. This can concern, for example, the duration of the retention interval (short-term, long-term or working memory) or the type of presentation (verbal or figural) of the information, which is why it is important to record the memory performance with different time intervals and materials in order to obtain the most precise picture of the disorder.
Why memory is an important criterion for neuropsychology?
Memory is the ability to retain, organize and later retrieve perceived information. Memory involves various function areas and processes that can be specifically impaired as a result of brain injury (Schuri, 2009). Since memory impairments can be mode-specific and can depend on the length of the retention interval (short-term or long-term), assessment needs to involve both different time intervals and different material (verbal, figural). Memory is thus not a homogeneous construct but consists rather of various subsystems (Thöne-Otto, 2009).
A well-known model of working memory is that of Baddeley (2000). The model distinguishes between the storage functions and the executive functions of working memory. The storage function of working memory is usually measured by quoting its capacity limit – i.e. the largest quantity or maximum amount of information that can be stored in it.
This is also termed short-term memory. Viewed thus, it can be seen that the model of working memory that goes back to Baddeley includes the concept of short-term memory (Schellig, 2011). The central executive is regarded as playing a key part in working memory, the main function of which is the maintenance and manipulation of information (Müller & Münte, 2009).
