• What is the sensory register in memory?


  A part of memory that holds stimuli from the environment
• How does a stimulus enter the sensory register?


  It passes into the sensory registers along with other sensory information
• What are the two main stores of sensory memory?

  • Iconic memory (visual information)
  • Echoic memory (auditory information)
• What is the duration of material in the sensory registers?


  Less than half a second
• What is the capacity of the sensory registers?


  Over one hundred million cells in one eye
• What is the key process that allows information to pass from the sensory register to further memory systems?

  Attention
• What is short-term memory (STM) known for?


  It is a limited capacity store
• What is the average capacity of STM?


  Between 5 and 9 items of information
• What is the 'magic number' associated with STM capacity?


  7 ± 2
• How is information in STM coded?


  Acoustically
• How long does information last in STM without rehearsal?


  About 30 seconds
• What is maintenance rehearsal?


  Repeating material to ourselves to keep it in STM
• What happens to information in STM if it is rehearsed long enough?


  It passes into long-term memory (LTM)
• What is long-term memory (LTM) known for?


  It is a potentially permanent memory store
• What is believed about the capacity of LTM?


  It is unlimited
• What did Bahrick et al. (1975) find about LTM?


  Participants recognized names and faces almost 50 years after graduating
• How is information typically coded in LTM?


  Semantically (in terms of meaning)
• What process is required to recall information from LTM?


  Retrieval
• According to the Multi-Store Model (MSM), how are memories recalled?


  They are transferred back into STM
• What is the role of the frontal lobe in memory?


  • Involved in processing and storing memories
  • Plays a role in attention and retrieval
• What is the significance of the sensory register in memory processing?


  It allows initial processing of environmental stimuli before further memory storage
• How does attention influence the sensory register?


  Attention determines what information is transferred from the sensory register to further memory systems
