Although previous reviews have examined specific aspects of nonverbal communication, their scope has generally been limited to particular settings or topics. For example, Lorié et al. (2016) conducted a systematic review of nonverbal expressions of empathy in clinical settings, focusing specifically on healthcare communication. To address this gap in the literature, the present scoping review systematically mapped comparative studies on nonverbal behaviors in cross-cultural communication published between 2010 and 2025. The aims were to identify the research methods used, the settings where studies were conducted, the main themes in the literature, and the remaining research gaps, as well as to examine the most frequently investigated NVBs across seven categories, including gestures, eye contact, facial expressions, posture, proxemics, haptics, and paralinguistic cues. A systematic search of academic databases identified 110 initial records. After screening and applying inclusion criteria, 43 studies were selected for final analysis. The results showed that gestures, eye contact, and facial expressions were the most commonly studied behaviors, while haptics, proxemics, and paralinguistic cues received less attention. Laboratory settings and literature-based studies were the most frequent research contexts, whereas real-world settings were less common. Quantitative methods, especially experiments and surveys, were used in most studies, while mixed-methods approaches were less frequent. A number of major themes emerged from the analysis, including cultural differences in specific behaviors, the functions and classifications of nonverbal cues, and cross-cultural misunderstandings in professional and educational contexts. The review also identified several gaps, including small sample sizes, limited use of direct observation, and oversimplification of cultural groups. The findings suggest that future research should pay greater attention to understudied NVBs such as haptics and proxemics, explore nonverbal communication (NVC) in real-world settings, and examine how digital cues such as emojis are interpreted across cultures. The review highlights the importance of cultural awareness in NVC for improving cross-cultural interactions in education and professional environments.
