The modulation of stimulus-preceding negativity as learning in the Monty Hall Dilemma task
Ii is known that the solution of the Monty Hall Dilemma (MHD) task is quite counterintuitive. However, it is also reported that the participants could “implicitly” learn the optimal solution of the MHD task through the repetitive exposure to the task.
We would tried to give a psychophysiological evidence into this learning by recording stimulus-preceding negativity (SPN), because Moris et al. (2013) showed that the SPN amplitudes, which were reflected by the informative value of feedback, were attenuated as learning.
As feedback became less informative with learning, the SPN amplitude decreased over the frontal region later in the task as well as the result of Moris et al. (2013). At the same time, aside from the effect of the informative values, the SPN amplitude was affected by the reward expectancy analogously to the results of Kotani et a. (2001) and Masaki et al. (2006).
