Stroop Effect

Logo for Stroop Effect
This is a simulation of the Stroop Effect experiment demonstrating the powerful interfernce effects of reading. Concise and clear text supports students' experience with the experiment. Personal, printable results are automatically generated for person who does the experiment. A plug in download is required. This Stroop Experiment is one component of the Internet Psych Lab (IPL). The IPL plugin download is found by navigating to Help, FAQs, IPL-Plugin.

Really nice interaction and a good demonstration of this basic experiment. Great for an online interaction in a class that might not meet face-to-face.

The interactive nature of the material is really great. Students can perform the Stroop task themselves and get a summary of their reaction time data, which makes this concept very concrete. The Stroop task reaction times are also compared to the "reverse" Stroop reaction times, demonstrating that the font color of the word interferes much less (if at all) with reading the word. For the college psychology student, I think it would have been helpful if this example used terminology common in classes and textbooks - describing the stimuli as incongruent and neutral, instead of "interference" and "normal" (congruent stimuli were not described). This could be something an instructor could talk about before students go through the simulation. Also, while the simulation does a good job of demonstrating the Stroop effect, the wrap up and explanation are a bit lacking for a college level course. After students complete everything, the instructor may want to explain why the reverse Stroop effect is so small (reading is a much more practiced skill than color naming, automatic and hard to inhibit), why the task might be easier when the response buttons are color patches instead of words (visual pattern matching, don't need to represent responses at a deeper, semantic level), or talk about how this task demonstrates selective attention.

Looking over the Stroop Test was interesting. I spent about an hour going over it and taking the tests. It stimulated my mind and was exciting to try to do. It stirred something up. I would be interested in learning more about the Stroop Effect and what it is all about. My curisoty is peeked.
Students will learn how much they rely on their reading skills. They will also realize how hard it is to change what is thought to be a simple project into a challenge.

Technical Remarks:

the test was easy to use. The directions were simple to follow. The difficulty came when the test was saying do this and your mind wanted to do something else.
My perception and thinking were challenged.
