Memory stores

• What is sensory memory?

  Short term retention of sensory information
• What are the sensory store made from?

  The sensory stores are made from our 5 senses
• What are the 5 senses?

  touch, smell, taste, hear, see
• What is iconic memory

  Memory of sight
• What is echoic memory?

  memory of sound
• How long does iconic memory last for?

  Less than half a second
• How long does echoic memory last for?

  2-4 seconds
• What is the capacity for the sensory memory?

  It can hold a lot of information so it is high
• What is encoding data in sensory memory?

  How information enters our memory through sensory input (5 senses)
• What is the capacity of short term memory?

  The capacity is limited
• How many pieces of information can the short term memory hold?

  5-9 pieces
• What is this memory store known as ?

  A temporary memory store
• How does encoding best work for STM?

  Through sound (speaking,music,words)
• What can happen to information from our STM and how does this happen?

  Information from our STM can be transferred into our LTM through rehearsal (going over) of the information
• How long does ST memory last?

  Up to 30 seconds
• Who found out that encoding for short term memory was best with sound?

  Alan Baddeley in 1966
• Who found out that capacity for STM was limited?

  George miller 1956
• Who found out information lasts for up to 30 seconds?


  Peterson and Peterson 1959
• What is the capacity for LTM?

  Unlimited
• What is the LTM store known as

  Potentially permanent memory store
• How does the information stay in our LTM

  Through rehearsal
• How do remember something that was lost in our LTM

  Through cues (triggers)
• What is the main way of encoding in LTM?

  Semantic - giving meaning to the information you are trying to remember
• Write the definition of sensory memory

  short term retention of sensory information
• Strengths of the memory stores

  • has practical applications - Capacity of STM can be increased through chunking (putting a word into chunks). By understanding the characteristics of memory stores can help improve memory
  • 3 memory store with different characteristics - all hold info for different lengths of time - differ so much in characteristics
• Weaknesses of Memory stores?

  • A lot of research is not typical of every day memory - in every day life we form memories related to useful things like faces and facts and places - more meaningful - Different characteristics of each memory store may not be so clear when using our memories in real life
