Eye-Movement-Based Instantaneous Cognition Model for Non-verbal Smooth Closed Figures

This study attempts to perform a comprehensive investigation of nonverbal instantaneous cognition of images through the "same-different" judgment paradigm using non-verbal smooth closed figures, which are difficult to memorize verbally, as materials for encoding experiments. The results suggested that the instantaneous cognition of non-verbal smooth closed figures is influenced by the contours' features (number of convex parts) and inter-stimulus intervals. In addition, the results of percent correct recognitions suggested that the accuracy of the " same-different" judgment may be influenced by the differences between the points being gazed when memorizing and recognizing and factors involved in the visual search process when recognizing. The results may have implications for the interaction design guideline about some instruments for visualizing a system state.
