Question 1

george sperling exp (3)

Answer 1

• duration & capacity of sensory memory
• all 9 letters stored in memory for a short period of time BUT only 4-5 could be recalled (iconic memory)
• could recall all 12 but time taken for verbal recount would cause them to disappear from memory
• tone to cue which row they had to recall

Question 2

john watson exp (3)

Answer 2

• behaviourism, “little albert”
• child conditioned to fear rat by pairing it w/ loud, frightening sound
• began to fear the rat & other similar objects showing STIMULUS GENERALISATION

Question 3

edward tolman exp (3)

Answer 3

• latent learning, cognitive maps w/ rats
• learning can occur w/o immediate reinforcement, challenges behaviourism (learn to navigate maze)
• develop mental map/internal rep off environ

Question 4

Albert bandura exp (

Answer 4

• social cognition “bobo doll
• learning can occur latently, rewards is what displays it
• observing model is how we learn, motivation causes behaviour to be reprod

Question 5

atkinson & shiffrins exp (5)

Answer 5

digit span task
1. digits VERBALLY presented
2. must recall in EXACT order
3. seq length would ^ until upper limit reached
* avg adult span 7+/- 2 items

Question 6

brown & peterson ex (3) + results (3)

Answer 6

AIM: measure decay of STM overtime
1. recall 3 consonants
2. memory probed @ 3s retention intervals (had to count backwards in 3s from a given # - distractor)
after 3 s interval - 50% recalled
after 9 s interval - 20%
after 12-18 s interval - 0%

Question 7

baddleys working model desc (3)

Answer 7

1. STM: CE, VSS, PL, EB
2. LTM: visual semantics, lang, episodic LTM
   3.active, multi component system for reasoning & prob solv (NOT PASSIVE MAINTENANCE OF INFO)
   explains dual-task performance
