    • Research Methods
      • Observation> possible explanation> testable statement> test of explanation> findings
    • Multi Store Model
      • Sensory > Attention > STM > Rehersal > LTM
      • Atkinson and Shiffrin 1968
      • Encoding, storage, retrieval, capacity, duration, LTM + STM
      • Sensory- 1-2s, large capacity        STM- 20s, acoustic   LTM- unlimited, semantic + acoustic
    • Working Memory Model
      • Visual semantics, episodic buffer, phonological loop (articularoty control, phono store) visuo spatial sketchpad
      • Cant pay attention to two things in same store at once

      • IVs- acoustically or semantically similar or dissimilar, results after 15 mins
