在人际交往中，身体姿势和非语言行为是传递社交信号的重要渠道，而这些渠道往往因文化而异。特定的身体姿势和动作不仅具有功能性元素，而且还具有情感性元素。例如，在日本，用双手将物体递给另一个人被认为是礼貌行为，而只用一只手则不被认为是礼貌行为。在这项研究中，我们研究了双手握持和单手握持是否会产生接收者大脑活动差异的迹象，以及这种活动在不同文化背景的人之间是否会有所不同。通过 48 通道近红外光谱 (NIRS) 测量 51 名女性参与者（25 名日本人和 26 名非日本人）的氧血红蛋白浓度变化。实验者用双手或一只手将一个瓶子递给参与者。结果显示，额下区域的氧-血红蛋白浓度变化量不同，具体取决于使用一只手还是双手。此外，日本参与者和非日本参与者的额下区域的大脑反应模式也有所不同。对氧合血红蛋白值差异的判别分析表明，下额叶区域右侧的氧合血红蛋白反应程度可以预测参与者属于哪一组。这些结果表明，不同的文化和习惯背景可能会导致在解释他人行为时出现不同的 NIRS 活动，并且 oxy-Hb IFG 浓度可能反映对他人行为的不同解释。
In interpersonal communication, body posture and nonverbal behavior serve as important channels for transmitting social signals and these often vary among cultures. Specific body postures and actions have not only functional, but also affective elements. For example, in Japan, handing an object to another with both hands is considered polite behavior whereas using only one hand is not. In this study, we have examined whether handing with both hands and handing with one hand would produce indications of differential brain activities in the receiver, and whether this activity would differ among people with different cultural backgrounds. Changes in oxyHb concentration were measured by 48-channel near infrared spectroscopy (NIRS) from 51 female participants (25 Japanese and 26 non-Japanese). The experimenter handed a bottle to participants using both or one hand. Results showed different amounts of change in oxy-Hb concentrations in the inferior frontal regions, depending on whether one hand or both hands were used. Moreover, the pattern of brain reactions in the inferior frontal regions differed between our Japanese and non-Japanese participants. A discriminant analysis of differences in oxy-Hb values suggested that the degree of oxy-Hb reaction in the right side of inferior frontal regions could predict to which group the participants belonged. These results suggest that different cultural and habitual backgrounds may lead to different NIRS activity while interpreting another’s actions, and oxy-Hb IFG concentration may reflect differential interpretations of another’s actions.
