Résumé	Signal Detection Theory (SDT) is a framework for analyzing how observers detect signals embedded in noise, accounting for both sensory capacity and decision-making bias. Developed by Green and Swets in the 1960s, it provides a principled method for measuring sensitivity and response criteria separately, making it foundational in psychophysics, perception research, and diagnostic decision-making.	The Stroop task is a classic measure of cognitive control and selective attention. Participants name the color of words while ignoring the words' semantic content. When the color and word meaning match (e.g., the word 'red' printed in red ink), responses are fast. When they conflict (e.g., the word 'red' printed in blue ink), response times increase dramatically. This Stroop effect reveals how automatic word reading interferes with color naming, indexed by the difference in reaction times between congruent and incongruent conditions.
