The multi-store model cases

• 15 words to remember
• Some recalled right after or 10 seconds delay
• primacy words- well remembered (transferred to LTM)
• recency words (near end)- badly remembered (still in STM)

• STM is a separe store from LTM, information has to be rehearsed or will disappear from STM

=) Control extraneous varibales, debriefing

=( Participant reactivity, psychological harm

• Children & adults
• Sequence of letters nd number- half-second interval

• The capacity of STM is 7 items
• Capacity in children is less than in adults

=) Control extraneous variables, debriefing

=( Participant reactivity, psychological harm

• tri-grams, recall after a delay
• asked to count backwards in 3
• recall of trigrams is very low after 20 seconds

• The duration of STM is about half a minute

=) Can control extraneous variables, debriefing

=( Participant reactivity, psychological harm 

• list of 5 words to remember
• recalled immediately before, came back next day and recalled again
• some sounded similar, some were semantically similar

• Acoustic encoding is important in STM
• Semantic encoding is important in LTM

=) can control extraneous variables, debriefing

=( participant reactivity, psychological harm

• Asked to identify people in old school photos
• tested knowledge in Spanish and Algebra
• people lose abuot 1% of info. per year
• memories can have a very long duration- perhaps a lifetime

• The duration of LTM can be as long as a lifetime

=) can control extraneous variables, debriefing

=( participant reactivity, psychological harm
