Evolutionary psychologists have hypothesized that men and women possess both long-term and short-term mating strategies, with men's short-term strategy differentially rooted in the desire for sexual variety. In this article, findings from a cross-cultural survey of 16,288 people across 10 major world regions (including North America, South America, Western(More)
Gender differences in the dismissing form of adult romantic attachment were investigated as part of the International Sexuality Description Project—a survey study of 17,804 people from 62 cultural regions. Contrary to research findings previously reported in Western cultures, we found that men were not significantly more dismissing than women across all(More)
As part of the International Sexuality Description Project, 16,954 participants from 53 nations were administered an anonymous survey about experiences with romantic attraction. Mate poaching--romantically attracting someone who is already in a relationship--was most common in Southern Europe, South America, Western Europe, and Eastern Europe and was(More)
This study examined whether interpersonal synchrony could be extracted using spectrum analysis (i.e., wavelet transform) in an unstructured conversation. Sixty-two female undergraduates were randomly paired and they engaged in a 6-min unstructured conversation. Interpersonal synchrony was evaluated by calculating the cross-wavelet coherence of the(More)
This study examined how gaze and speech rate affect perceptions of a speaker. Participants viewed a video recording of one of four persuasive messages delivered by a female speaker. Analysis of speech rate, gaze, and listener's sex revealed that when combined with a small amount of gaze, slow speech rate decreased trustworthiness as compared to a fast(More)
We propose a cup-shaped device called Cup-le for conversational experiment. Cup-le has various sensors to record participants’ nonverbal behavior such as utterance. Cup-le saves the work of attaching sensors. Also, since Cup-le appears cup-shaped, it can sense without being aware of the sensor unlike conventional wearable sensors. Moreover, by attaching(More)
We conducted this study in order to examine the relationships between early adult attachment styles and social adjustment, such as mental health and self-perception in the context of close relationships. Questionnaires were administered, 460 undergraduates participated in the study, and their data were analyzed. Results showed that secure attachment was(More)
This study examined how people can handle the multiple audience problem of self-presentation (Fleming, 1994), when faced with two or more audiences while simultaneously wanting each audience to form or maintain a different impression of the presenter. In the laboratory, female participants had a brief conversation with either an opposite-sex (male) or a(More)
This study examined the influence of affect on interpersonal relationships in a dyadic communication context. The combination of speakers' affective states was considered, as compared to previous studies which considered only the individual's affective state. The independent variables, in a between-subjects design, were affective condition (positive vs.(More)
A hierarchical data analysis was conducted using data from couples to examine how self-reports of interactions between partners in romantic relationships predict the quality of the relationships. Whereas the social exchange theory has elucidated the quality of relationships from the individual level of subjectivity, this study focused on the structure of(More)
