| 内容記述 | Sense of agency (SoA) refers to the subjective experience that a voluntary action causes specific outcome in the outside world. The core questions in SoA research are (1) whether it is built on a predictive or postditive way, and (2) how the valence of the outcome influences SoA. These questions are remained unclear, but behavioral studies of self-serving bias indicate that the valence of the outcome biases action atribution or SoA retrospectively. To investigate the relationship between SoA and the outcome of action, intentional binding (IB) will be useful. As Haggard propesed origninally, IB is an implicit measure of SoA. Here, we show the results of 15 healthy subjects using a modified version of Libet clock timing paradigm. In the conditioning block, subject learned the combination of tones and valences (positive, neutral and negative monetary outcome). After conditioning, subjects played slots while watching a clockhand rotation. They were asked to press a key at a time of their own choice. Then, one of 3 beeps was presented randomly after a 250 ms delay, which informed the outcome of the slot. After a clock hand disappeared, subjects reported the perceived timing of either an action or a beep. These timing estimates were compared with baseline blocks where subjects judged either an action or a beep in a single event trial. In our study, subjects showed considerable binding effects regardless of the valence of outcome. However, the degree of temporal compression was attenuated significantly when negative outcome occurred as compared to positive and neutral outcomes. Our results not only confirm the postdictive account of SoA, but also demonstrate that the valence of the outcome influence SoA. | |||||
