Another variant of the classic Stroop effect is the reverse Stroop effect. It occurs during a pointing task. In a reverse Stroop task, individuals are shown a page with a black square with an incongruent colored word in the middle—for instance, the word "red" written in the color green (red)—with four smaller colored squares in the corners ...
The numerical Stroop effect, a concept rooted in cognitive psychology, refers to the interference that occurs when individuals are asked to compare numerical values or physical sizes of digits presented together. The effect arises when there is a mismatch—or incongruity—between the numerical value and the physical size of the digits.
Stimulus–response (S–R) compatibility is the degree to which a person's perception of the world is compatible with the required action. S–R compatibility has been described as the "naturalness" of the association between a stimulus and its response, such as a left-oriented stimulus requiring a response from the left side of the body.
Both the standard Stroop effect and the emotional Stoop task have high test-retest reliability. [7] [8] There are variations to the emotional Stroop task; participants may not always be asked to identify the color of the word presented to them, but instead they may be asked to respond to other stimuli present. [9]

Parallel processing has been linked, by some experimental psychologists, to the stroop effect (resulting from the stroop test where there is a mismatch between the name of a color and the color that the word is written in). [5] In the stroop effect, an inability to attend to all stimuli is seen through people's selective attention. [6]
A variation of this task is the Counting-Stroop, during which people count either neutral stimuli ('dog' presented four times) or interfering stimuli ('three' presented four times) by pressing a button.
This process leads to an interaction called the Gratton effect, which is the finding of a lower interference effect after an incongruent trial compared to the effect after a congruent trial. On this first trial (trial n) the incongruent stimulus presented will lead to an increase in conflict detected by the ACC.
