ABSTRACT
Scanpaths, repetitive sequences of saccades, were observed to develop during first viewing of a picture and reoccurred early in a reviewing session with a recognition task. The scanpath story opened up a new experimental paradigm in cognitive science, there were important deficits in the original Noton-Stark experiments. These included the requirement for a richer set of pictures and scenes. When studying perceptual eye movements that cover an extensive vertical and horizontal range in angular degrees and include many oblique ones having both horizontal and vertical components, the problem of linearization and of independence of the horizontal and vertical components becomes an important one. The next important part of the program is the identification of the automatic fixation sequence. In order to study interrelationships between Markov matrix entries and eye movement traces, it was decided to carry out a series of simulation studies whereby matrices with sample sets of entries would generate artificial eye movements in an artificial scanpath pattern.
