Figure 1 from Experiment 2 of the original description of the Stroop Effect (1935). 1 is the time that it takes to name the color of the dots while 2 is the time that it takes to say the color when there is a conflict with the written word.
John Ridley Stroop (/ s t r uː p /; March 21, 1897 – September 1, 1973), better known as J. Ridley Stroop, was an American psychologist whose research in cognition and interference continues to be considered by some as the gold standard in attentional studies and profound enough to continue to be cited for relevance into the 21st century.
Like the standard Stroop effect, the emotional Stroop test works by examining the response time of the participant to name colors of words presented to them. Unlike the traditional Stroop effect, the words presented either relate to specific emotional states or disorders, or they are neutral (e.g., "watch", "bottle", "sky"). For example ...
The Simon effect is the difference in accuracy or reaction time between trials in which stimulus and response are on the same side and trials in which they are on opposite sides, with responses being generally slower and less accurate when the stimulus and response are on opposite sides. The task is similar in concept to the Stroop Effect. [1]
The Stroop color–word task utilizes the Stroop effect to observe the distractor suppression and negative priming. Identification tasks present a set of images, sounds, words, symbols, or letters and require the subject to select the prime target based a particular feature that differentiates the target from the distractor.
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]
More than one study have reported findings of a reduced Stroop effect following mindfulness meditation training. [45] [53] [54] The Stroop effect indexes interference created by having words printed in color that differ to the read semantic meaning e.g. green printed in red. However findings for this task are not consistently found.
The original Stroop effect is asymmetrical - color responses are slowed down by irrelevant words but word reading is commonly not affected by irrelevant colors. [3] [4] Unlike the Stroop effect, the numerical Stroop effect is symmetrical – irrelevant sizes affect the comparisons of values and irrelevant values affect comparisons of sizes.
