Different Conceptual Approaches Share assumption:

lawful regularities between inputs and outputs

• Behaviorism – A Black Box Approach
• Cognitivism – A White Box Approach
• Infer the process!

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

You have two buckets; one holds 5 gallons the other 7 gallons. You need to measure out exactly 4 gallons.
Tower of Hanoi
• Three pegs
• Three Discs: Large medium: Small
• Start with all three discuss on peg 1 in order from top: small, medium, large
• Move all discs to peg 3, one at a time:
• Never put larger disc on top of smaller disc
• What are the fewest moves possible?
