Influence of reward expectation on ocular information during a controlled card game
Minoru Nakayama, Kouhei Shoda (Tokyo Tech.) HIP2019-60
Abstract (in Japanese) (See Japanese page) 
(in English) Evoked reward expectations were measured during a card game playing while influence for oculo-motor
indices were observed. As the result, pupil sizes increased with the degree of reward expectations though frequency of saccades were surpressed. Also, indices of micro saccades (MSs) were extracted from eye movements. Frequencies of MSs depended on degree of reward expectation and magnitudes of low frequency powers. Chronological analysis for these relationships showed that there are significant difference in pupil diameters between two levels of reward expectations during the last 12 seconds. Also there are no significant difference in MS frequencies between the two levels.
