  1. UNIT 4 – AOS 1 - MEMORY TERM 2 REFRESHER

  2. What we have learnt so far that we must not forget..... • P-VALUES • ENCODING, STORAGE AND RETRIEVAL • MEASURES OF RETENTION • ATKINSON AND SHIFFRIN MODEL OF MEMORY • SENSORY MEMORY: Function/Capacity/Duration • ECHOIC MEMORY • ICONIC MEMORY • SHORT TERM MEMORY: Function/Capacity/Duration • ALLAN BADDELEY’S WORKING MEMORY MODEL

  3. P-VALUES • In scientific research, an alpha level of 0.05 significance is used as a benchmark to gauge whether a difference obtained in the findings is truly due to the influence of the independent variable and not attributed to chance. • Stricter probability values (P) of significance are sometimes employed, such as p< 0.01 (less than 1 in 100); p< 0.001 (less than 1 in 1000). • p< 0.07 p< 0.006 p< 0.049 p< 0.04 p< 0.5 p< 0.001 p< 0.001 p< 0.061

  4. ENCODING, STORAGE AND RETRIEVAL Incoming Sensory I N F O R M A T I O N Encoding Storage Retrieval Information is converted for storage Information is retained in memory Information is recovered from memory when needed

  5. Relative Sensitivity of the Measures of Retention High Sensitivity Relearning Retention Retrieval Recognition Cued Recall Serial Free LowSensitivity Savings score= (original trials) – (trials for relearning) (original trials)

  6. Three Types of Memory – Atkinson and shiffron model Encoding and Storage I N F O R M A T I O N Sensory Memory (SM) Attention Short Term Memory (STM) or Working Memory (WM) Long-Term Memory (LTM) Retrieval Forgotten Forgotten if not encoded or rehearsed. Decay: not being used Displacement: pushed out Lost if not attended to

  7. SENSORY MEMORY: Function/Capacity/Duration ATKINSON AND SHFRIN MODEL OF MEMORY

  8. ECHOIC MEMORY AND ICONIC MEMORY

  9. SHORT TERM MEMORY: Function/Capacity/Duration 7 + 2 Short – Term Memory holds Seven +Two items
