Imagine That Some Researchers Are Trying to Design a Computer-Simulation

Imagine that some researchers are trying to design a computer-simulation model for an arithmetic task. They would be most likely to

A) begin by using the single-cell recording technique, and then gradually shift to the fMRI technique.
B) design a system that solves each arithmetic problem as quickly as possible.
C) examine the way people's strategies change as they become more familiar with the task.
D) create a system that uses a problem-solving technique that is similar to the way humans would solve the problem.
