Why do people prefer social sharing of emotion with conversational AI over human partners? A structural topic modeling approach Reviewed International journal
Yuki Nozaki
Computers in Human Behavior: Artificial Humans 7 100260 2026.3
Publisher：Elsevier BV
The social sharing of emotion, traditionally studied in human-to-human interactions, is increasingly occurring with conversational AI systems. However, the specific motives for preferring AI over human partners for this purpose remain relatively underexplored. The present study aims to identify these motives and examine their associations with individual differences—namely, frequency of conversational AI usage, social anxiety, and self-esteem. Open-ended survey responses from 178 university students, describing situations in which they would prefer to share emotions with conversational AI rather than with human partners and their reasons for this preference, were analyzed using structural topic modeling to identify key themes and their relationships with individual difference variables. The analysis revealed five primary motives: (1) talking things over casually, (2) seeking emotional connection, (3) venting as an alternative to a close confidant, (4) seeking objective advice, and (5) consulting on topics difficult to discuss with people. Moreover, higher social anxiety was significantly associated with greater endorsement of consulting on topics difficult to discuss with people. This research provides an empirically derived taxonomy of motives for sharing emotions with conversational AI, highlighting that individuals perceive AI as a partner capable of fulfilling specific socio-affective needs by leveraging its unique features, such as its nonjudgmental nature and constant availability. The findings contribute to a deeper understanding of the evolving landscape of human–AI relationships.

Bridging supportive communication and interpersonal emotion regulation: An integrative review Reviewed International coauthorship International journal
Yuki Nozaki, James J. Gross
Journal of Social and Personal Relationships Advance online publication ( 8 ) 2231 - 2262 2025.4
Authorship：Lead author, Corresponding author Publisher：SAGE Publications
Social interactions that support people who are experiencing negative emotions are ubiquitous in a wide array of interpersonal relationships. These social interactions are referred to as supportive communication . Decades ago, Burleson and Goldsmith (1998) first noted a connection between supportive communication and emotion regulation, with the goal of explaining the underlying mechanisms by which supportive messages change the recipient’s negative emotions. Since then, contemporary emotion regulation theory has matured, and now can explain a broad range of supportive communication processes via the expansion of interpersonal emotion regulation research and the development of the process model of emotion regulation. This paper aims to describe how contemporary advances in emotion regulation theory and research can shed light on dynamic processes in supportive communication. We then discuss the implications of this updated view for both research fields and show how it can advance interdisciplinary research.

Instrumental motives in emotion regulation of one’s own and others’ anger: Testing cross-cultural similarities and differences between European Americans and Japanese Reviewed International journal

Authorship：Lead author, Corresponding author Publisher：SAGE Publications
Instrumental motives, such as increasing negative emotions to facilitate performance, are one of the primary motives in regulating one’s own emotions (i.e., intrinsic emotion regulation) and others’ emotions (i.e., extrinsic emotion regulation). However, most instrumental emotion regulation research has been conducted in Western countries, even though desired emotions, such as anger, could vary across Western and Eastern cultures. This research investigates cross-cultural similarities and differences between European Americans and Japanese in instrumental motives for regulating one’s own (Study 1) and others’ anger (Study 2). To this end, the two preregistered studies used the context of playing an aggressive or nonaggressive computer game, a common methodology used in previous research on instrumental anger regulation. The results showed that both European Americans and Japanese significantly preferred angry stimuli for themselves and their partners before playing an aggressive game over a nonaggressive one. We also found that European Americans preferred anger stimuli significantly more than Japanese, although these cultural differences were neither large nor robust. Furthermore, individual differences in the perceived utility of anger were positively associated with a preference for angry stimuli, whereas cultural self-construals were not significantly associated with a preference for angry stimuli among either European Americans or Japanese. This research provides novel evidence for the cross-cultural similarity of instrumental anger regulation in both intrinsic and extrinsic emotion regulation between European Americans and Japanese.

Development of a model of the psychological mechanisms explaining the enhancement of autonomous emotion regulation through interaction with conversational AI

Authorship：principal_investigator
With the development of large language models, there has been progress in the development of conversational AI that can be used for encouragement and consultation. On the other hand, there are also concerns that excessive reliance on AI could undermine human autonomy. This research will construct a model of the psychological mechanisms explaing the enhancement of autonomous emotion regulation through interaction with conversational AI, based on a theoretical framework of psychology that respects human dignity while being supported by scientific evidence. It will contribute to the realization of a society in which humans and AI thrive together.
