• So how to you solve the problem?
Formulas or procedures (step-by-step) that automatically generate correct
E.g. mathematically and chemical formulas, sequenced routines.
Cost: may be time consuming.
o Heuristic- “rule of thumb”, strategies.
General Problem- solving strategies that we apply to certain classes of situations
Mental short cuts
Lotto ticket example- same probability of picking any numbers even if they are
• So what makes it possible for you to solve the problem?
Subroutines- allocating resources
• Testing your automatic processing
o The stroop effect
o See coloured disks
o Say out the colour you see- row 1 left to right, then row 2
• Stroop effect- we are fully automatized (saying different coloured words)
o You will see a decline in activity because of this
• Problems in problem solving:
o Mental set: stay with one approach to the problem
o This is what happened with the last two sets of volume problems
o Functional Fixedness
