On the basis of an interdependence analysis, it is proposed that commitment to a close relationship is associated with cognitive interdependence—a mental state characterized by a pluralistic, collective representation of the self-in-relationship. A cross-sectional survey study and a 2-wave longitudinal study revealed that strong commitment to a romantic(More)
The present work advances and tests an interdependence-based model of the associations among commitment, pro-relationship behavior, and trust. Findings from two longitudinal studies revealed good support for model predictions. Commitment-inspired acts such as accommodation and willingness to sacrifice provide diagnostic information regarding a partner's(More)
Leucine-rich repeats and immunoglobulin-like domains-1 (LRIG1) is a transmembrane protein with an ectodomain containing 15 leucine-rich repeats (LRRs) homologous to mammalian decorin and the Drosophila kekkon1 gene. In this study, we demonstrate that a soluble ectodomain of LRIG1, containing only the LRRs, inhibits ligand-independent epidermal growth factor(More)
This research adopted an interdependence analysis of sacrifice, examining the link between commitment (i.e., the subjective experience of dependence and long-term orientation) and willingness to sacrifice in ongoing close relationships, and determining whether this link is moderated by preexisting individual differences in social value orientation (i.e.,(More)
Little research has examined the effects of prejudice and discrimination on people's romantic relationships. The authors explored whether belonging to a socially devalued relationship affects consequential relational phenomena. Within the framework of the Investment Model, the authors (a) tested the association between perceived relationship marginalization(More)
Although the concept of investments in romantic relationships has featured prominently in close relationships research, there have been no empirical analyses of different types of investments and their possible differential predictive power regarding relationship state or fate. With data from five independent samples, the authors offer and examine(More)
Release of the hormone cortisol represents a distress response to novel or stressful situations. Individual differences in such reactivity have been conceptualized as representing a relatively enduring, generalizable trait. In this study, cortisol responses to two experimentally manipulated "sexual" and "nonsexual" stressors were used to examine whether(More)
Decorin is not only a regulator of matrix assembly but also a key signaling molecule that modulates the activity of tyrosine kinase receptors such as the epidermal growth factor receptor (EGFR). Decorin evokes protracted internalization of the EGFR via a caveolar-mediated endocytosis, which leads to EGFR degradation and attenuation of its signaling pathway.(More)
The investment model of commitment processes is rooted in interdependence theory and emerged from the broader scientific zeitgeist of the 1960s and 1970s that sought to understand seemingly irrational persistence in social behavior. The investment model was developed originally to move social psychology beyond focusing only on positive affect in predicting(More)
The current study examines the trajectories of student perceived gains as a result of time spent in an undergraduate research experience (URE). Data for the study come from a survey administered at three points over a 1-yr period: before participation in the program, at the end of a Summer segment of research, and at the end of the year. Repeated-measures(More)
