L – L = A L – R = B R – L = B R – R = C
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 • 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
Explanations • 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
Predictions ME ST Ex • List Length • Target Location • Target + or -
Predictions MESTEx • List Length no yes/no yes • Target Location no yes no • Target + or - no yes no
Which hypothesis is Correct? • Exhaustive Serial Search
