types of memory

• What is the definition of sensory memory?

  Initial stage of memory where sensory information is stored for a brief period
• What is the duration of sensory memory?

  Very short (milliseconds to a few seconds)
• What is the capacity of sensory memory?

  High capacity for sensory stimuli
• What is an example of iconic memory?

  Visual stimuli
• What is an example of echoic memory?

  Auditory stimuli
• What research supports the capacity of iconic memory?

  SPERLING (1960) demonstrated the capacity of iconic memory
• What is a limitation of the sensory memory model?

  It oversimplifies memory processes by not accounting for complex interactions
• What is the definition of short-term memory (STM)?

  A temporary storage system for actively processed information
• What is the duration of short-term memory?

  20-30 seconds without rehearsal
• What is the capacity of short-term memory according to Miller's magic number?

  7 +/- 2 items
• What is the primary encoding method for short-term memory?

  Primarily acoustic
• What did Baddeley (1966) find about short-term memory encoding?

  STM is often coded acoustically
• What is a limitation of the short-term memory model regarding encoding?

  The emphasis on acoustic encoding may not apply to all types of information
• What is the definition of long-term memory (LTM)?

  A relatively permanent storage system for processed information
• What is the duration of long-term memory?

  Potentially unlimited
• What is the capacity of long-term memory?

  Unlimited
• What is the primary encoding method for long-term memory?

  Primarily semantic (based on meaning)
• What did Bahrick et al. (1975) demonstrate about long-term memory?

  They demonstrated the long duration and potential capacity of LTM
• What is a limitation of the long-term memory model regarding types?

  The distinction between LTM types is too simplistic
