| 内容記述 | The Bayesian brain framework has been proposed as a new interpretation of placebo/nocebo effect. According to the framework, the placebo/nocebo effect are regarded as a result of active inference process for decreasing prediction error. A similar process i s observed in perception of ambiguous visual stimuli, and the hysteresis effect is one of the examples of the process. As the hysteresis effect is a representative effect that the prior knowledge impact on present perception, a deep understanding of the h ysteresis effect may contribute to the unraveling of the placebo/nocebo effect. However, precise research about the effect of hysteresis effect on perception has scarcely been explored. Moreover, it has been reported that individual differences in the degr ee of utilization prior knowledge to ambiguous visual stimuli, any research about the relationship between the individual personality and hysteresis effect have not been done. We aimed to clarify the relationship between the hysteresis effect and visual pe rception with signal detection theory and personality traits using the Big five inventory (FFI, NEO FFI).Ninety two healthy subjects underwent a visual hysteresis task and NEO FFI questionnaire online. The perceptual sensitivity increased, and the criterion decreased through the hysteresis task. The significant correlation between agreeableness from NEO FFI a nd hysteresis effect was observed. Our results suggested that people with high agreeableness tend to make greater use of prior knowledge,and further investigation of this field may be helpful in improving the accuracy of prediction of placebo responder. | |||||||
