A widespread perspective describes emotions as distinct categories bridged by fuzzy boundaries, indicating that emotions are distinct and dimensional at the same time. Theoretical and methodological approaches to this perspective still need further development. We conceptualize emotions as overlapping networks of causal relationships between emotion components—networks representing distinct emotions share components with and relate to each other. To investigate this conceptualization, we introduce network analysis to emotion research and apply it to the reanalysis of a data set on multiple positive (...) emotions. Specifically, we describe the estimation of networks from data, and the detection of overlapping communities of nodes in these networks. The network perspective has implications for the understanding of distinct emotions, their co-occurrence, and their measurement. (shrink)

Co-speech hand gestures offer a rich avenue for research into studying emotion communication because they serve as both prominent expressive bodily cues and an integral part of language. Despite such a strategic relevance, gesture-speech integration and interaction have received less research focus on its emotional function compared to its cognitive function. This review aims to shed light on the current state of the field regarding the interplay between co-speech hand gestures and emotions, focusing specifically on the role of gestures in (...) expressing and understanding both others’ and one's own emotions. The article concludes by addressing current limitations in the field and proposing future directions for researchers investigating gesture-emotion interaction. Our goal is to provide a roadmap to researchers in their exploration of the role of gestures in emotions, ultimately contributing to a more comprehensive understanding of how gestures and emotions intersect.

Most emotion theories recognise the importance of the body in expressing and constructing emotions. Focusing beyond the face, the present research adds needed empirical data on the effect of static full body postures on positive/negative affect. In Studies 1 (N = 110) and 2 (N = 79), using a bodily feedback paradigm, we manipulated postures to test causal effects on affective and physiological responses to emotionally ambiguous music. Across both studies among U.S. participants, we find the strongest support for an (...) effect of bodily postures that are expansive and oriented upward on positive affect. In addition, an expansive and upward pose also led to greater cardiac vagal reactivity but these changes in parasympathetic activity were not related to affective changes (Study 2). In line with embodied theories, these results provide additional support for the role of postural input in constructing affect. Discussion highlights the relevance of these findings for the study of religious practices during which the postures studied are often adopted. (shrink)
