Abstract: The goal of this research was to imitate the process of visual search in a natural two-dimensional situation and also to investigate the influence of variable features on the speed of the visual search. The experiment was designed upon one of the most influential theories in the research field of the visual search phenomenon – The Feature Integration Theory (Treisman, 1982). Although the FIT theory claims, that in case of a larger number of synchronous targets the mechanism of attention serially directs the mental processing from one target towards another, the results of our experiment has shown the possibility of not just serial but also parallel visual search. The results of the experiment have also shown that the similarity between features of the target and its surroundings takes effect on the speed of the target recognition. If the features are very similar or if there is no difference between the target and its surroundings, the visual search for the target is longer in comparison to the visual search for the target, which features don't resemble the target's surroundings.
