the ability to summon up from memory a particular bit of information. Often spoken of as retrieval memory or recall. When one retrieves or recalls bits of information because of casual stimulation, it is referred to as retrieval, but most discussions in a school setting are related to demand retrieval. That is, a demand is placed on the individual to retrieve particular information now (as in a test). It is often the demand aspect (to do it now), a demand imposed by someone else, that causes the trouble for people with retrieval problems. Some people can retrieve stored or remembered information, but they are very slow to do so. This, too, is a retrieval problem.
