Q

Trace Decay Delay

A
  • The longer the animal views the stimulus the higher the correct %
  • The longer the delay between sample and comparison the lower the % correct
  • Decay rates were consistently parallel over time meaning there were two factors making memory stronger or weaker
  • Sample leaves a trace longer the sample on the longer the trace
  • Trace decay is constant because the decay and the trace don’t influence each other

Q

3 types of Control Processes

A
  1. Maintenance Rehearsal - Repetition of an item - Atkinson & Shiffrin 1977
  2. Levels of Processing Theory - Craik & Lockhart 1972

Q

Levels of Processing Theory

A
  • Craik & Lockhart
  • Not about the number of repetitions but the quality of the control processes that help us remember it
  • The deeper level of processing the more the remembering
  • Put concepts into sentences as a deep process

Q

Working memory

A
  • Baddeley & Hitch 1974
  • A system with limited capacity for manipulation of stimuli, recall of memories, comprehension, complex cognition
  • Stores and processes stimuli here so that we can carry out a task

Q

Recent Research - Central Executive

A
  • Is actually many separate mental processes at once
  • Evidence for this is found in brain injury.
  • Lesions in certain areas of the brain disable some Central Executive abilities but not all of them
  • This suggests that Central Executive exists in several different aspects of brain function

Q

Do Deaf People Have a Phonological Loop

A
  • Deaf people have a sign length effect instead of word length effect longer signs require more processing that short signs

Q

Lee Brooks 1968 - Visuospatial Sketch Pad Interference

A
  • Subjects who only had to call out their responses were faster
  • Subjects who had to point as well as speak were slower
  • A task with a phonological + Visuospatial element was quick
  • Those with phonological + 2 Visuospatial elements was slow
  • This show that visual and auditory information is processed separately.
