The effect of moods on visual awareness(Summary of Awarded Presentation at the 27th Annual Meeting)

抄録

This study used a bistable plaid motion pattern to examine whether mood can modulate visual awareness. After either a happy or sad mood was induced the participants observed for three minutes a moving plaid pattern created by superimposing two gratings in different orientations. The participants indicated whether they perceived the motion pattern as two surfaces sliding in different directions (component motion) or as a single plaid pattern (pattern motion). The results revealed that participants in a happy mood reported longer durations of the component motion than those in sad or neutral induced mood. The results suggest that a happy mood enhances tracking multiple motion patterns whereas a sad or neutral mood leads to focused perception of a single object motion.
