Bottom Line: For the visual detecting time changes, the first factor, Group, was significant as a main effect (F(1,22)=6.49, p<0.05) as well as the second factor, Training (F(3,66)=5.06, p<0.01).Similarly, for the number of correct reactions, there was a main effect of a Group factor (F(1,22)=23.40, p<0.001), a main effect of a Training factor (F(3,66)=11.60, p<0.001) and a significant interaction between factors (Group vs.Training) (F(3,66)=10.33, p<0.001).

ABSTRACT
In this study, we conducted an experiment in which we analyzed the possibilities to develop visual skills by specifically targeted training of visual search. The aim of our study was to investigate whether, for how long and to what extent a training program for visual functions could improve visual search. The study involved 24 healthy students from the Szczecin University who were divided into two groups: experimental (12) and control (12). In addition to regular sports and recreational activities of the curriculum, the subjects of the experimental group also participated in 8-week long training with visual functions, 3 times a week for 45 min. The Signal Test of the Vienna Test System was performed four times: before entering the study, after first 4 weeks of the experiment, immediately after its completion and 4 weeks after the study terminated. The results of this experiment proved that an 8-week long perceptual training program significantly differentiated the plot of visual detecting time. For the visual detecting time changes, the first factor, Group, was significant as a main effect (F(1,22)=6.49, p<0.05) as well as the second factor, Training (F(3,66)=5.06, p<0.01). The interaction between the two factors (Group vs. Training) of perceptual training was F(3,66)=6.82 (p<0.001). Similarly, for the number of correct reactions, there was a main effect of a Group factor (F(1,22)=23.40, p<0.001), a main effect of a Training factor (F(3,66)=11.60, p<0.001) and a significant interaction between factors (Group vs. Training) (F(3,66)=10.33, p<0.001). Our study suggests that 8-week training of visual functions can improve visual search performance.

f3-jhk-46-231: White signals (dots) on a black background and critical stimulus constellation in the Signal Test

Mentions: The Signal Test measured the visuospatial differentiation of a relevant signal within irrelevant signals. This test evaluates the visual detailed registration of complex stimuli under time pressure over a longer period of time by constantly engaging oculomotor functions, e.g. pursuit and saccadic eye movements and steadiness of binocular fixation during the task. In our experiment, we utilized a standard version S1 with white signals (dots) on a black background. Dots were displayed over the whole screen area, pseudo-randomly some of the dots vanished and other came into view. The participants were asked to perform a key-press response to a programmed stimulus constellations whenever it took place. This critical stimulus constellation was created by four dots which together formed a square (Picture 1). Each of the subjects was prepared for the main task by participating in pre-tests that enabled them to familiarise themselves with the apparatus and the task itself. The total testing time was about 20 minutes (including instruction and practice phases). The main variables calculated were the numbers of correct, omitted and incorrect reactions, and the median reaction time as a measure of the speed of the detection process.
