The MASS is not only currently the most common tool for measuring levels of mindfulness, but is also considered important for adequately representing the core concept of mindfulness (Brown & Ryan, 2003；Chang, 2013). The auditory oddball task is a simple and easy-to-operate task, and it is usually used to elicit MMN and P300. MMN is not only an automatic auditory stimulus-discrimination process that discriminates change in a situation, but is also considered an important index of pre-attention (Näätänen, Paavilainen, Rinne,& Alho, 2007; Srinivasan & Baijal, 2007). P300 is an attentional index related to conscious awareness, and it is usually used to examine the extent of attentional engagement. In a literature review, this study found the following problems: (1) Studies have rarely examined the relationship between the MAAS and MMN. (2) The majority of past studies investigated the effects on MMN and P300 of mindfulness meditation training, rather than the relationships between dispositional mindfulness and MMN and P300. Therefore, this study designed two experiments in order to examine, respectively, the relationship between the MAAS and MMN, and the relationship between the MAAS and P300. Method: The first experiment examined the relationship between the MAAS and MMN, and the second experiment examined the relationship between the MAAS and P300. In each experiment, the auditory oddball task was used to elicit MMN and P300. The task consisted of a standard stimulus (500 Hz) and oddball stimulus (1000 Hz); 80% of the stimulus presentations in each trial were the standard stimulus and 20% were the oddball stimulus, with the stimuli being presented in a random sequence. In the first experiment, the participants were not required to count the number of oddball stimuli, but in the second experiment, they were. Results and Conclusion: The results in the first experiment did not demonstrate a correlation between the MAAS and MMN. The results in the second experiment demonstrated a positive correlation between the MAAS and P300 amplitude. This study manipulated “attention engagement” in the two experiments, and the results demonstrated that dispositional mindfulness was related to the ability to exert attentional control, such that cultivating dispositional mindfulness would enhance the ability to exert attentional control .
