Introduction Short-term memory Short term memory is part of the memory storage system which is capable of storing material for a brief period of time and to some extent it determines how well the rest of your intelligences are utilized. At any one time short term memory can contain seven, plus or minus two, "chunks" of information. If short term memory tries to acquire more items than it can handle, the middle items will often be displaced. Items remain in short term memory around twenty seconds. Substantial evidence exists to support a general dependency of reasoning upon short term memory capacity. The longer information is stored in short term memory the easier it is to manipulate information needed in the execution of complex cognitive tasks (e.g. short term memory has been shown to be correlated with problem solving, learning, reasoning, and reading comprehension). One of the models that attempts to explain how working memory functions is the multi component model of working memory. The articulator loop and the visuo-spatial sketch pad are responsible for short term maintenance of information and the central executive is responsible for coordinating these two systems. The articulatory loop stores phonetic information, for example numbers that we repeat to ourselves as soon as we learn them and the visual-spatial sketch pad stores visual and spatial information. The central executive is responsible for processing the information gathered by the other two components and determining which information is relevant. Another model proposed by Graeme Halford suggests that short term memory can be better defined as the ability to create or distinguish relationships between items or elements. For example in the following sentence "In metropolitan areas budget hotels charge excessively for internet access whereas expensive hotels in seaside resorts charge more
