L – R = B

R – L = B

R – R = C

L – R = B 1 + 2 = 3

• 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

• 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
