L – L = A

L – R = B

R – L = B

R – R = C

slide12

L – L = A 1 + 1 = 2

L – R = B 1 + 2 = 3

R – L = B 2 + 1 = 3

R – R = C 2 + 2 = 4

methodology
Methodology
  • Mental Inference (Deduction)
    • Statement of facts
    • How can facts be as they are?
    • Attribute as much as possible to observables

Clever Hans

    • Infer unobservable process:
      • List of competing hypotheses
      • Experimental hypothesis testing
      • Achieve tentative satisfaction

Sternberg’s Memory Search
  • Task: random list of single digit numbers
  • Lists visually presented
  • Delay
  • Target: a digit that was or was not on list
  • DV: Reaction Time

  • Minds Eye
    • Examine entire list at once
  • Self-Terminating Serial Search
    • Scan memory of digits serially until
      • Target found
      • Or end of list
  • Exhaustive Serially Search
    • Scan entire list
