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

Question 8

holway & boring exp (4)

Answer 8

• Investigating Depth Cues
• Observers sat @ intersection of 2 corridors & could view a test circle in 1 corridor & comparison circle in another
• Task: adjust the size of the comparison circle to match the test circle
• Differing depth cues were progressively removed in different conditions. (Binocular disparity, Motion parallax, Shadows etc.)

Question 9

desc ames room (2)

Answer 9

• Size illusions.
• specially designed room created to be viewed through a peephole that made the room appear to be normal so that when 2 participants stood in corners of the room, they would appear to be much larger/smaller than in reality.

Question 10

desc Suchow & Alvarez exp (3)

Answer 10

• Motion induced change-blindness.
• circle of colourful dots that change colour
• As the circle rotates, the colour-changes becomes difficult to notice, providing evidence for motion induced change-blindness as a result of transient signals associated with all observed objects which disrupts preferential attention, so changes go unnoticed.

Question 11

Carassco et al exp (3)

Answer 11

• Attention and Contrast
• Observers were req to the report the orientation of the higher contrast grating even when both gratings were identical in contrast.
• When observers were cued to a certain grating, that grating appeared higher in contrast.

Question 12

Treisman & Schmidt exp

Answer 12

• Illusory Conjunctions
• When character strings are presented briefly followed by a noise mask, observers are then asked to report coloured letters
• frequently associated w/ the wrong colour due to the inhibition of Feature Integration theory.
