Аннотация:In the current study we analysed the influence of cognitive style on visual search process in a modelled graphical interface environment. The participants had to find the target stimulus in a 9x9 matrix with 81 images, commonly used in web design. Search time and eye movement data were recorded.
The subjects were divided into two groups according to their Matching familiar figures test score: impulsive and reflective (Kagan, 1966; Carretero-Dios et al., 2008). Impulsive subjects tended to find the stimulus faster than reflective subjects (F(2;1983)=5.1;p<0.05), demonstrated shorter mean fixation duration (F(2;1983)=3.5;p<0.05) and shorter dwell time on the areas of interest (F(2;1983)=7.1;p<0.05). Furthermore, we identified sequential and non-sequential visual search patterns, using the combination of intersaccadic angle and saccade direction measures (Amor et al., 2016; Blinnikova, Izmalkova, 2017). We opted a three cluster solution with two sequential patterns, characterized by prevalence of smaller intersaccadic angles (mostly 0o-45o), which differed in prevailing saccade direction (horizontal or vertical), and one non-sequential pattern, characterized by larger amount of intersaccadic angles with 45o-135o values. Significant distinctions were found in Impulsivity score in different patterns (F(4;1248)=4.7 (p<0.05)): impulsive subjects tended to demonstrate non-sequential pattern and reflective subjects preferred sequential patterns, especially the horizontal sequential pattern.This research is supported by the Russian Foundation of Basic Research; Grant №17-06-00652.
