Short Term Memory - created from Mind Map

Capacity 7+/- 2 items of information Miller 1956 -found out that most people could only repeat back between five and nine items Chunking can increase the capacity of short term memory. For example: GCSE

Duration Peterson and Peterson 1959 Aim: Establish the duration of short term memory when Rehearsal is prevented Participants heard a Trigram which was held up to 30 seconds. They were asked to recall it immediately or recall it after a set of retention interval:3,6,9,12,15 or 18 seconds. During the period before recall, they were asked to count backwards in 3's from a specified number to prevent  Maintenance Rehearsal Conclusion: Without Rehearsal, the duration of STM is only a few seconds

Encoding  Encoding :The way the information is put into each store : Acoustic form Conard 1964 Aim: To establish the form in which information is encode into STM Participants were shown a sequence of six letters.They were asked to write them down as the appeared,but the presentation ran to fast for them to keep. Therefore, keeping the information in STM. Participants often made acoustic errors, where the letters that they had seen were replaced by those that sound simular. Even when the information is presented visual,encoding was acoustically
