the multi store model of memory

• What is the focus of the memory unit in the psych boost series?


  The focus is on two models of memory, types of long-term memory, reasons for forgetting, and eyewitness testimony.
• What is the cognitive approach in psychology?


  The cognitive approach studies mental processes such as memory, perception, and problem-solving.
• What are the main components of the multi-store model of memory?


  • Sensory register
  • Short-term memory
  • Long-term memory
• What are the three features to remember for each store in the multi-store model?


  The three features are coding, capacity, and duration.
• What is the coding of the sensory register?


  The coding of the sensory register is modality specific.
• What is the capacity of the sensory register?


  The capacity of the sensory register is very large, potentially unlimited.
• What is the duration of the sensory register?


  The duration of the sensory register is approximately 250 milliseconds.
• How does information move from the sensory register to short-term memory?


  Information moves from the sensory register to short-term memory through attention.
• What is the coding of short-term memory?


  The coding of short-term memory is acoustic.
• What is the capacity of short-term memory?


  The capacity of short-term memory is seven items plus or minus two.
• What is the duration of short-term memory?


  The duration of short-term memory is between 18 and 30 seconds.
• What are the two types of rehearsal for transferring information to long-term memory?


  The two types are maintenance rehearsal and elaborative rehearsal.
• What is maintenance rehearsal?

  Maintenance rehearsal is repeating information to keep it in short-term memory.
• What is elaborative rehearsal?


  Elaborative rehearsal involves linking new information to existing knowledge in long-term memory.
• What is the coding of long-term memory?


  The coding of long-term memory is semantic.
• What is the capacity of long-term memory?


  The capacity of long-term memory is very large, potentially unlimited.
• What is the duration of long-term memory?


  The duration of long-term memory is very large, potentially unlimited.
• What does the primacy-recency effect suggest about memory?


  It suggests that long-term and short-term memory are separate processes.
• What did Sperling's study demonstrate about sensory memory capacity?


  Sperling's study suggested that sensory memory has a much larger capacity than short-term memory.
• What did Baddeley's study reveal about short-term memory coding?


  Baddeley's study revealed that short-term memory is coded acoustically.
• How does chunking affect short-term memory capacity?


  Chunking increases the capacity of short-term memory by grouping items together.
• What did Peterson and Peterson's study find about the duration of short-term memory?


  Peterson and Peterson found that the duration of short-term memory is between 18 and 30 seconds.
• What did Wagner's diary study suggest about long-term memory capacity?


  Wagner's diary study suggested that the capacity of long-term memory is very large.
• What did Barrack's study reveal about the duration of long-term memory?


  Barrack's study revealed that the duration of long-term memory is potentially unlimited.
• What are the criticisms of the multi-store model of memory?


  • Research methods lack ecological validity.
  • Tasks lack mundane realism.
  • The model is simplistic and suggests unitary stores.
  • Assumptions about memory processes may lack face validity.
• Why is the multi-store model considered simplistic?


  It is considered simplistic because it suggests that short-term and long-term memory are unitary and passive stores.
• What is a potential problem with the inferences made from memory research?


  A potential problem is that the inferences could be wrong, leading to incorrect conclusions about memory processes.
• How does evolutionary theory support the sensory register's features?


  It supports the sensory register's features by suggesting that quick reactions for survival require processing important information efficiently.
• What is the significance of the multi-store model in psychology?


  The significance lies in its explanation of how information is processed and stored in different memory systems.
• What are the key terms associated with the multi-store model of memory?

  • Sensory register
  • Short-term memory
  • Long-term memory
  • Coding
  • Capacity
  • Duration
• Short Term Memory holds info that we need to use immediately or within the next few seconds
• Sensory Memory has a very short duration (less than half a second) but can hold an unlimited amount of info
• The Sensory Register is where sensory information from our eyes, ears, nose etc are stored.
• Information held in STM can be rehearsed (repeated) which allows us to hold onto it longer
• STM lasts around 18 secs but can be extended through rehearsal
• STM has limited capacity - only 7 items +/- 2
• Retrieval is when info is brought back out of long term memory
