Visuomotor Choice Reaction

The program "Visuomotor Choice Reaction" allows you to evaluate a complex visuomotor reaction, the choice reaction. The program allows you to choose the number of attempts in a stage (from 5 to 20). Also, there is a "Demo" mode where the order of passing the test is offered for familiarization (2 attempts at each stage).

The program "Visuomotor Choice Reaction" has three modes of passing the test:

1. Test tasks that include reactions to color and shapes;

2. Test tasks that contain reactions to color only;

3. Test items that contain only shapes.

In each mode, you can choose the time of visual stimuli occurrence: 3...5 s; 2...5 s, 2...6 s, 3...8 s.

The first mode of the test is the main one, and the following modes can be considered as training. 

The test task (the first test mode) is divided into four stages, from simple to complex, in terms of the impact on the sensory system. The reaction time to the shapes will be longer because there will be more details to comprehend. The first stage is the reaction to color stimuli, the second stage is the reaction to color stimuli when counteracting disturbing stimuli, the third stage is the reaction to shapes, the fourth stage is the reaction to shapes when counteracting disturbing stimuli.

The time of occurrence of visual stimuli in the computer program was chosen in the range from 3 s to 5 s, which allows to obtain an acceptable duration of the entire test. The test duration, with 10 trials per stage (about 40 trials for the entire test) is about 3 minutes.

The interfering stimuli are colored balls or shapes. During the stage, they move chaotically across the screen of the mobile device with different speeds and image intensities (from 20% to 90%). The range of values for the appearance and change of the confounding stimuli is from 0.2 s to 2.0 s. The duration of stimulus movement relative to random coordinates is 0.3 s, which ensures sufficient dynamics of their movement on the screen of a mobile device.

The following shapes are selected for the test task: Cylinder, Octahedron, Cube, Sphere, Square Pyramid. These shapes are the most recognizable. The color of the shapes is gray, as an achromatic color, so that the test taker reacts to the shape, not the color.
