The Effect of Visual Field Position and Type of Stimuli on the Stroop Effect

Abstract The effects of lateralization and consistency on the reaction time of named colors were experimentally tested. This was done using a computer program provided by the University of Mississippi. This effect is called Stroop effect. The results show that although lateralization and consistency have no significant effect on reaction time, the interaction of these two variables produces a significant change in the time required to discriminate between colors . This is thought to be due to different hemispheric functions of the brain.

Stroop effect is one of the most famous phenomena in cognitive psychology. The Stroop effect occurs when you perform the Stroop task that is explained and demonstrated in this course. Stroop effect is related to selective attention. This is the ability to respond to specific environmental stimulus while ignoring other environmental stimuli. In the Stroop task, people only need to see words with colors such as blue, red, and green. Interestingly, this task is to specify the ink color of the printed word, completely ignoring the meaning of the actual word. This shows that it is very difficult, you can know exactly how difficult it is.

The stimulation of the Stroop paradigm can be divided into three groups: neutral, consistent, and contradictory. Neutral stimulation is a stimulus that displays only text (stimulus 1 resembling Stroop experiment) or color (Stimulation 3 similar to Stroop experiment). A consistent stimulus is that the ink color and word refer to the same color (eg the pink word "pink"). A contradictory stimulus is stimulation of different ink colors and words. In the Stroop experiment, three experimental results were found repeatedly. The first finding is semantic interference, which indicates that the ink color naming the neutral stimulus (eg, if the ink color and words do not interfere with one another) is faster than the contradictory condition. Since it is generally considered that the semantic relationship between ink colors and words is the cause of interference, it is called semantic interference. When the color of ink matches a word than when there is a neutral stimulus)
