    "abstract": "Eye movements are a behavioral response that can be involved in tasks as\ncomplicated as natural image classification. This report confirms that pro- and\nanti-saccades can be used by a volunteer to designate target (animal) or\nnon-target images that were centered 16 degrees off the fixation point. With\nmore than 86% correct responses, 11 participants responded to targets in 470\nmilliseconds on average, starting as quick as 245 milliseconds. Furthermore,\ntracking the gaze position is considered a powerful method in the studies of\nrecognition as the saccade response times, ocular dynamics and the events\naround the response time can be calculated from the data sampled 240 times per\nsecond. The Hilbert transform is applied to obtain the analytic signal from the\nhorizontal gaze position. Its amplitude and phase are used to describe\ndifferences between saccades that may testify to the recognition process.",
