曖昧さへの態度がメンタライジングに及ぼす影響

It has been suggested that the mentalizing stance, which is an exploratory attitude accompanied by curiosity about one’s own and others’ mental states, requires a high level of tolerance of ambiguity, that is, the ability to withstand ambiguity. However, there are no studies that have examined the relationship between these aspects. In addition, previous studies have shown that it is desirable to examine not only the level of tolerance of ambiguity but also multidimensional attitudes, since there are multiple aspects in the evaluation of ambiguity. Further, the mentalizing stance is merely one aspect of mentalizing, and it is possible that there are differences in how other aspects are affected by attitudes toward ambiguity. Therefore, in this study, we examined how not only the mentalizing stance but also mentalization and the accuracy of the mentalizing of others are influenced by attitudes toward ambiguity. The results indicated that the mentalizing stance requires an attitude of proactive involvement toward ambiguity rather than a high degree of tolerance of ambiguity. It was also suggested that mentalization necessitates an attitude that allows for intelligent interpretations of ambiguity. Furthermore, it was shown that an attitude of dealing with ambiguity without sufficiently addressing it decreases the accuracy of the mentalizing of others. Therefore, it is suggested that mentalizing requires an attitude of active engagement with and interpretation of ambiguity rather than the ability to tolerate ambiguity.
