Selective attention task
The Stroop effect is the delay in reaction time between congruent and incongruent stimuli. 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 - with four smaller colored squares in the corners. One square would be colored green, one square would be red, and the two remaining squares would be other colors. Studies show that if the individual is asked to point to the color square of the written color (in this case, red) they would present a delay. Thus, incongruently-colored words significantly interfere with pointing to the appropriate square. However, some research has shown there is very little interference from incongruent color words when the objective is to match the color of the word. Source: Stroop effect.
These 2 excellent researches were taken as a starting point in the development of this application:
The design of the research had to be changed to adapt to the operation of this application in a web environment.
It is possible to customize the language interface (eg enter color names in your own language). A form for changing application settings is included.
