L5 STM

• According to Miller, how many items can we hold in our STM?

  7+/- 2 items
• What is the primacy recency effect?

  The primacy recency effect refers to the tendency for people to remember the first and last items in a list more easily than the middle items. Primacy effect reflects the LTM, and recency effect reflects the STM
• What was the case of HM?

  His LTM did not work, but he had normal STM
• What was the case of KF? (Shallice & Warrington)

  Normal LTM but STM impaired: digit span reduced to max 2
• What are the factors in the working memory model (Baddeley & Hitch)

  Central executive: integrates information.

  Visuo-spatial sketch pad: STM store for the manipulation of visual and spatial information

  Phonological loop: STM store for speech based codes
• Baddeley et al 1975: short words better recalled than long words - amount of items correctly recalled is not 7, but whatever can be uttered in about 2 seconds.
