The Jacobi Iteration of Eigenvalue of Real Self-Adjoint Quaternion Matrices

The emergence of location-based real-time dating (LBRTD) apps such as Tinder has introduced a new way for users to get to know potential partners nearby. The design of the apps represents a departure from “old-school” dating sites as it relies on the affordances of mobile media. This might change the way individuals portray themselves as their authentic or deceptive self. Based on survey data collected via Mechanical Turk and using structural equation modeling, we assess how Tinder users present themselves, exploring at the same time the impact of their personality characteristics, their demographics, and their motives of use. We find that self-esteem is the most important psychological predictor, fostering real self-presentation but decreasing deceptive self-presentation. The motives of use—hooking up/sex, friendship, relationship, traveling, self-validation, and entertainment—also affect the two forms of self-presentation. Demographic characteristics and psychological antecedents influence the motives for using Tinder, with gender differences being especially pronounced. Women use Tinder more for friendship and self-validation, while men use it more for hooking up/sex, traveling, and relationship seeking. We put the findings into context, discuss the limitations of our approach and provide avenues for future research into the topic.

This paper first reviews three different theoretical constructs concerning the psychological significance of sex role related characteristics in personality functioning: sex role identity, androgyny, and sex role transcendence. A new conceptual analysis concerning sex-typing, sex role strain analysis, is presented. According to this analysis, the relationship between sex role related personality characteristics and psychological adjustment, especially self-esteem, is moderated by two variables: perception of the ideal member of the same sex, and sex role salience. These two variables; taken in conjunction with real self-concept, generate five sex role strain outcomes. The constructs of sex role identity, androgyny, and sex role transcendence are interpreted in terms of this sex role strain analysis. The implications of this analysis for current research and for understanding the dynamics of both individual and social change in sex roles are briefly described.
