Mary believes that she is an excellent math student. In fact, her favorite unit is statistics. However, when she is asked to critically evaluate the data of a experiment in psychology class, she does not know how to do it. How does the Dual Process model explain this?
She has developed the System 2 thinking necessary for math class, but not for psychology class.
Her knowledge from mathematics is interfering with her knowledge in psychology.
She is not able to transfer her understanding in mathematics to a new context (situation). So, her approach to solving the problem shows System 1 thinking.
Mary's self-esteem in psychology class is interfering with her ability to solve the problem. It has nothing to do with System 1 and System 2 thinking.
