Learning activity 6.7 1. Short term memory (STM) is a memory system with a limited storage capacity in which information is stored for a relatively short period of time, unless renewed in some way. 2. The storage capacity of the STM is very limited. It has the capacity to hold 5 to 9 units of information at any one time. 3. The storage duration of the STM is fairly well for the first few seconds. After about 12 seconds recall starts to decline and by about 18 seconds almost all of the information disappears entirely if it has not been renewed in some way. 4. STM is alike to sensory memory in the sense that the information lasts for roughly the same amount of time (short) but is unlike it in the sense of its capacity (STM has a very limited capacity compared to sensory & LTM). 5. F 6. STM is described as working memory because it is used to emphasise the active part of memory where information we are consciously aware of is actively ‘worked on’ in many ways. Working memory enables us to consciously use information from sensory memory and LTM. I think working memory is more appropriate because when we are consciously paying attention to sensory information we are ‘working’ the short term memory. 7. Information might be forgotten if it is not rehearsed to remain in our LTM or if we are distracted by new information which pushes out the information already in our STM. LEARNING ACTIVITY 6.11 1. Chunking is the grouping or packaging of separate bits of information into a larger single unit or ‘chunk’ of information. 2. Maintenance rehearsal involves repeating the information being remembered over and over again so that the information can be retained in STM. Elaborative rehearsal is the process of linking new information in a meaningful way with the other new
