Douglas is working on a project for his cognitive psychology class. he? builds a plastic model of the human brain, paints each major structure a different color, and constructs a "map" that shows which functions are controlled by which brain component. douglas's project is working from a(n) model of cognitive psychology.

Douglas's project is working from a structural model of cognitive psychology.

In ,structural model of cognitive psychology, we only analyze a single cognitive phenomenon or process (such as making decision, learning, fight or flight) etc.
By mapping each brain for its specific function, i believe Douglass' project is really close to this model.
