Cognitive Impact of Eye Movements in Picture Viewing

We compared and analyzed eye tracking experiments to test the hypothesis that the patterns generated during picture viewing were mainly determined by eye movement generated links. Eye movement data were collected from participants who viewed photographs of artistic portraits during an active viewing. The links as determined by a popular evolutionary computational model, based on Genetic Algorithm, did not anticipate saccade sequences of eye movements. The optimized Genetic Algorithm (GA)-generated graphs differed considerably from the graphs generated by eye tracking. The existing evidence is consistent with the hypothesis that cognitive and, in turn, metacognitive factors take part in active gazing of eyes. The pattern generated by eye movements can only be substantiated with cognitive processes.
