About This Resource: The Stroop Effect is a well-known psychology experiment that demonstrates how automatic mental processes (like reading a word) can interfere with a separate cognitive task (like naming the ink color the word is printed in). This 2-minute interactive demo from Stafford & Associates Counseling gives clients a firsthand experience of how automatic, deeply learned responses can override conscious intention — a concept that shows up often in therapy when working with ingrained thought patterns, habits, and reactive emotional responses.
