Atkinson-Shiffrin Multi Store Model of Memory

The multi-store model of memory....

• describes a flow of information through three separate memory stages in a fixed order.
• describes a flow of information through three separate memory stores in a fixed order.
• sees memory as a byproduct of processing.
• suggests that memory has 4 separate memory storages.

Which of the following provides the best definition for the sensory memory store? 

• All the stimuli that bombard our senses are retained in their original sensory form (i.e.., as exact copies) for a very brief time.
• All the stimuli that bombard our senses are retained in their original sensory form (i.e.., as exact copies) for up to 30 seconds.
• All short term memories are retained as exact copies for a very brief time.
• All the stimuli that bombard our senses are retained in their original sensory form (i.e.., as exact copies) for a potentially unlimited time

What is the capacity of sensory memory?

• A fraction of a second
• Up to 30 seconds
• Unlimited
• 7 + or - 2 bits of information

What is the duration of iconic memory?

• up to 30 seconds
• unlimited
• 7 + or - 2 bits of information
• about a third of a second

What happens to information in sensory memory that we DO NOT attend to?

• It is transferred to STM
• It remains in sensory memory
• It is lost 
• It is transferred back to sensory memory.

What were the results of the first stage of Sperling's research study into recall and tones (High Medium and Low)?

• Most participants could recall only four or five letters in each set.

• Most participants could recall most of the letters in each set.

• Most participants could recall only one row of letters in each set.

• The participants could recall all of the words in whichever row correspond with the tone.

What were the results of the second stage of Sperling's study?

• Once participants learned the system, they were able to repeat the top row of letters with perfect accuracy.
• Once participants learned the system, they were able to repeat all rows of letters with perfect accuracy.
• Once participants learned the system, they were able to repeat any row of letters (that corresponded with the tone) with perfect accuracy.
• Most participants could recall only four or five letters in each set. 

What is the capacity of Short Term Memory?

• 7 plus or minus 2 bits of information.

• unlimited

• 30 seconds

• 15 to 17 bits of information

According to the multi-store model, what is the duration of short term memories if they are not renewed in some way?

• 7 plus or minus 2 bits of informaiton.

• unlimited

• a fraction of a second

• around 18-30 seconds

According to the multi-store model, what the capacity and duration of long-term memory?

• Relatively permanent capacity and unlimited duration.
• Semi permanent capacity and unlimited duration.
• Unlimited capacity and relatively permanent duration.
• Semi-permanent duration and unlimited capacity.
