Abstract

The aim of this research was to examine the accuracy of face recognition of left-handers and right-handers when the faces are presented to the left visual field and right visual field. The sample comprised 49 male participants, between 18 and 30 years of age, 24 of them left-handed and 25 right-handed. Participants took part in the experiment that consisted of tree parts. In the first part 20 photographs were briefly presented to participants to their left or right visual field in random arrangement. The second part of the experiment consisted of the inserted task in duration of 10 min. In the third part of the experiment, participants were presented with 40 photographs, 20 from the first part of the experiment and 20 new ones, and, as a response required for further analysis, the accuracy of face recognition person in the photograph was recorded. The data analysis confirmed our assumption that participants would better recognize faces on photograph when they were presented in the right visual field then in the left visual field. Furthermore, our data analysis did not confirm our assumption that right-handers would be more successful in face recognition compared to left-handers. The expected lack of interaction between hand dominance and visual field was also confirmed.
