What is computational modeling?
- It is not the same as a process model or a structural equation model
- It is governed by mathematical relationships, and requires computation because it would take too long to do it all by hand (usually because there are complex relationships that require many computations).
- Typically one sets up a simulation with the desired parameters and lets the computer run. One then looks at the output (whatever that may be, usually the experimenter knows ahead of time what they want to look at) to interpret the behavior of the model.
Why would you want to use a computational model?
- In short, to do something that is hard or impossible to do with a lab experiment.
- If too many people are involved for it to be practical
- If you want to simulate things that current technology doesn't allow us to measure
- To validate with a more detailed model a hypothesized process derived from actual lab data
- To propose a theory and test it for things that are not currently observable or practical.
