The two factors of 'gender-identity' (whether the speaker is male or female) and 'gender-congruence' (whether or not the gender of speaker and listener is the same) can be assumed to act differently in determining levels of politeness. To investigate this assumption, the present study was designed to analyze university student politeness levels in Japan and South Korea when they (i.e., speakers) asked various people (i.e., listeners) to purchase a concert ticket. A decision tree analysis revealed hierarchies of factors predictive of politeness levels specific to young Japanese and Koreans. Among Japanese, distance (i.e., extent to which speaker and listener are acquainted) was the strongest followed by power (i.e., extent of disparity in social status) and gender-identity/gender-congruence. Among Koreans, however, power appeared to override distance, resulting in the descending order of power and gender-identity/gender-congruence. Regarding gender-related factors, the results of these parallel studies in Japan and South Korea generally suggested a distinctive influence of gender-identity on politeness levels when listeners held equal or lesser power than speakers, while gender-congruence was implicated when listeners held greater power.

Abstract
Previous studies suggested the possibility that the red nucleus (RN) is involved in other cognitive functions than motion per se, even though such functions have yet to be clarified. We investigated the activation of RN during several tasks and its intrinsic functional network associated with social cognition and musical practice. The tasks included finger tapping, n-back, and memory recall tasks. Region of interest for RN was identified through those tasks, anatomical information of RN, and a brain atlas. The intrinsic functional network was identified for RN by an analysis of connectivity between RN and other regions typically involved in seven known resting state functional networks with RN used as the seed region. Association of the RN network with a psychological trait of the interpersonal reactivity index and musical training years revealed subnetworks that included empathy related regions or music practice related regions. These social or highly coordinated motor activity represent the most complex functions ever known to involve the RN, adding further evidence for the multifunctional roles of RN. These discoveries may lead to a new direction of investigations to clarify probable novel roles for RN in high-level human behavior.
