Stroop Effect

A detailed Summary of Stroop Effect

The Stroop effect shows how selective attention is utilized to attend to a task that requires the subject to selectively focus on one of several different stimuli. Stroop's findings can be seen in parts of everyday life, such as a mother being able to hear her own child's cry over many other children in the same room.

The Stroop experiment tests the ability to name the ink color of colored words under conditions where the word meanings and ink colors varied. The dependent variable, that which can be measured, is the time that it took each subject to accomplish each conditioned task, and the independent variable being the different task conditions. The different conditions were marked and defined as follows:

A. Words written in their corresponding colors, known as the strong Stroop

B. Mismatched colored words written in the color of ink of the word to follow, known as negative priming

C. Incongruent ink colored words, known as the weak Stroop

D. Ink colored irrelevant words, know

A B C D E

Mean 14.55 37.38 31.75 22.25 20.5

The study examined the hypothesis that the greater the interference required in the condition, called the weak Stoop, the more amount of time it would take to read. Therefore, the predicted pattern of conditions from fastest to slowest would be A, E, D, C, and B.

E. Ink colored XXX's, known as neutral patterns

There are circumstances encountered everyday that require the need to switch attention back and forth between two or more stimuli. The need to focus or divide attention is largely determined by the demands of the user's tasks. Such as, driving a car while talking on a cell phone. There are trade-offs in attention requirements, some automatic in nature, others need deliberate focus to accomplish. An argument could be made for an additional experiment by changing the font size, or by using color overlays that would slightly fade the ink color in varying degrees to see if the Stroop theory could still be validated.
