Q

Outline the procedure of cognitive modeling

A
  1. Reformulating a psychological theory mathematically
  2. Researching some of the numerical parameters for the completion of step 1 empirically
  3. Compare ability of resulting models to explain real-life data
  4. Use results to reformulate the theoretical framework
