Answer 1

  IV: amount of stimulus (dots)
  DV: ability to discriminate signal from noise

Question 2

Metacontrast masking

Answer 2

4 squares but 1is not - time varies and sometimes they appear together or right after each other (target vs mask stimulus)
IV: SOA
DV: proportion correct

Question 3

Spatial cueing

Answer 3

arrow pointing to where target will be (80% its points in correct direction) - neutral vs valid/invalid cue
IV: arrow
DV: how quick

Question 4

Attentional blink

Answer 4

DV: reaction time

Question 9

Simple detection

Answer 9

how quick can you respond after green circle appears after a random amount of time
IV: time of stimulus appearing - SOA
DV: time taken to click
