This study examined the influence of visual inducing stimulus on choice tasks in a computer. Subjects were asked making a series of choices to be random order for two items presented repeatedly on the computer screen. At some choices, an inducer (an arrow or a CG character) was appeared at the center between two items and indicated either item. Results showed that subjects tended to avoid the item indicated by the inducer, especially when the inducer was the arrow. The phenomenon is similar to psychological reactance to restore the freedom from a restricted circumstance. Moreover, the strength of the reactance depended on subject's personality trait "openness to experience" measured in big-five scale.
