Which of the following statements is most accurate about human brain modularity? System 1 uses heuristics, while system 2 is more calculating; most decisions are made by system 1. System 1 uses heuristics, while system 2 is more calculating; system 2 regularly overcomes system 1's heuristics to make decisions. Both systems regularly use both heuristics and conscious calculations; both are equally important in decision making. System 1 uses heuristics, while system 2 is more calculating; both are equally important in decision making.

Behavioral economists stated that the human brain is very efficient but it is usually susceptible or prone to errors. They believed that the human brain uses evolutionary-developed heuristics to make most decisions. The human brain often uses and employs heuristics as they save energy and time in decision making.

Heuristics

This is often refered to as short passway or shortcuts that save time and energy in decision making.

Module

This is simply known as particular organ or subsystem of the brain which is said to be genetically specified to perform a some special functions.

Modular brain function

This is known as a separate or different localized regions of the brain that are mostly specialized to perform specific functions.
