Memory Storage Types

  • sensory memory - the shortest-term element of memory
    • echoic memory - auditory sensory memory
      • phonological loop -
    • iconic memory - visual sensory memory
      • visuospatial sketchpad -
    • neocortical sensory and motor buffers -
  • working memory - considered short-term memory that is active instead of temporary storage system
  • short-term memory - temporary information storage system that holds about 7 items
    • a method called chunking can help to increase the capacity of short-term memory
  • long-term memory - can store a seemingly unlimited amount of information almost indefinitely
    • implicit - unconsciously recalled
    • explicit - consciously recalled
      • declarative - facts and events
        • contextual or associative
          • episodic or autobiographical -
          • retrospective - what happened in the past
          • prospective - things to remember in the future
        • non-contextual or non-associative
          • semantic - more structured: abstract and relational
          • familiarity -

Transitions Between Memory Storage Types

  • SM can become STM through the process of attention
  • STM can become LTM through the process of consolidation:
    • rehearsal
    • meaningful association
    • Motivation
  • LTM to STM is a process of retrieval
