What is the Origin of Stroop Test?

The test was first published by American psychologist John Ridley Stroop in 1935, and its utility has since expanded from experimental psychology into clinical neurology and geriatrics. The test's enduring relevance stems from its ability to isolate and quantify the phenomenon of cognitive interference. In hormonal health, it is used to indirectly assess the functional status of hormone-sensitive prefrontal cortex regions.

What is the Mechanism of Stroop Test?

The mechanism of the Stroop effect relies on the brain's processing speed and its ability to engage the anterior cingulate cortex and prefrontal regions for conflict resolution. The automatic process of reading the word must be inhibited by the executive function required to name the ink color. Hormones like testosterone and estrogen can influence the speed of neural transmission and executive control, meaning a patient's performance can serve as a functional biomarker of their neuroendocrine status.

Meaning

The Stroop Test is a standardized neuro-psychological assessment tool used clinically to measure a patient’s selective attention, cognitive interference, and executive function speed. It requires the subject to name the color of a word that is itself a different color name, forcing the brain to suppress an automatic response in favor of a non-automatic one. The test’s outcome is a valuable, objective measure of cognitive reserve and neurological efficiency, often used to track the efficacy of hormonal interventions.
