Abstract

When facing a goal-stimulus, people have a certain degree of attention. Therefore, when stimulus has changes in 2D or 3D configuration, in which cases one would react faster or slower? The present research evaluated the influence of the changes in the characteristics of the stimuli in reaction time experiments in visual attention tasks in videogames made in Unity 3D. For this, a comparison was made between two videogame experiments. The first videogame experiment was divided into two blocks that showed stimuli a block in 2D videogame and another in 3D videogame respectively to the participants and collected their reaction times against these stimuli. The second videogame experiment increase the number of blocks (from two to eight) to explain the differences in the reaction times obtained in the first experiment either by the size or the relative angle of 3D presentation of the stimuli, for which some characteristics of the blocks of the first experiment. The results, after comparing the different scenarios, have shown that the modification of the characteristics changed selective attention, because the reaction times of the first experiment vary in comparison to those of the second experiment depending on the change made (between 65 and 67 ms of difference for 2D and between 53 and 77 ms for 3D). On the discussion, one can question the commercial spheres of 2D stimuli in the so-called neuromarketing or sports. In both scenarios, the present work suggests evaluating for each case changes in their presentations or tools in a consequent control the reaction time of potential users, and this translates into a level of attention control.
