SHORT TERM MEMORY
Otherwise known as working memory, this is for data that is used and forgotten almost instantly. The capacity of the working memory is limited to 5 plus/minus 2 items (7 plus/minus 2 accrding to the old syllabus), which can be stored for an average period of 15 to 20 seconds. Some information can last in short-term memory for up to a minute if rehearsal strategies are used. The information in short-term memory is also highly susceptible to interference. Any new information that enters short-term memory will quickly displace old information. Similar items in the environment can also interfere with short-term memories.

• To avoid forgetting working memory contents, information must be transferred to the long-term memory. Chunking is one memorization technique that can facilitate the transfer of information into long-term memory. Chunking consists in grouping data for the working memory to recognize them as one item only. Easily remembered mnemnic phrases, abbreviations, or rhymes can also help move short-term memories into long-term storage.
