Sculpting Narcissus: A dyadic perspective on narcissism and buffering effects of perceived ideal self affirmation on relationship commitment
Narcissistic self-regulation strategies aimed at pursuing a grandiose self can undermine relationship commitment. This study examined whether Michelangelo phenomenon mechanisms, whereby partners facilitate each other’s ideal selves through affirmation processes, can mitigate these potentially detrimental effects. Across three dyadic survey-based studies ( Ns = 107, 212, 213 romantic couples), our findings demonstrated that perceiving a partner as…
The impact of non-harmonious goals on partner support and taking on opportunities
Romantic partners often support each other to progress toward goals. However, at times partners’ goals are not in harmony and conflict with partner or relationship needs, leading to negative consequences for couple members. The present study examined whether non-harmonious opportunities were associated with support provider’s and recipient’s behavior, perceived partner support, and goal outcomes. We further examined whether these effects were mod…
A Machine Learning Approach to Predicting Perceived Partner Support From Relational and Individual Variables
Perceiving one’s partner as supportive is considered essential for relationships, but we know little about which factors are central to predicting perceived partner support. Traditional statistical techniques are ill-equipped to compare a large number of potential predictor variables and cannot answer this question. This research used machine learning analysis (random forest with Shapley values) to identify the most salient self-report predictors…
Self-Efficacy and Declines Over Time in Attachment Anxiety During the Transition to Parenthood
Attachment anxiety can decline in relationships but little is known about how or why. A new framework—the Attachment Security Enhancement Model (ASEM)—suggests that what allays current (momentary) insecurity may not necessarily reduce attachment anxiety across time. This article differentiates momentary versus extended attachment processes by examining concurrent versus longitudinal associations. Cohabitating partners ( N = 137 couples) were exam…
Machine learning uncovers the most robust self-report predictors of relationship quality across 43 longitudinal couples studies
Significance What predicts how happy people are with their romantic relationships? Relationship science—an interdisciplinary field spanning psychology, sociology, economics, family studies, and communication—has identified hundreds of variables that purportedly shape romantic relationship quality. The current project used machine learning to directly quantify and compare the predictive power of many such variables among 11,196 romantic couples. P…
Mind the Gap: Perceived Partner Responsiveness as a Bridge between General and Partner-Specific Attachment Security
A core idea of attachment theory is that security develops when attachment figures are responsive to a person’s connection needs. Individuals may be more or less secure in different relationships. We hypothesized that individuals who perceive a current relationship partner as being responsive to their needs will feel more secure in that specific relationship, and that the benefits of perceived partner responsiveness would be more pronounced for i…
Investigating mechanisms of social support effectiveness: The case of locomotion motivation
Although social support can entail costs, individuals with a higher locomotion orientation, who are motivated to move and take action, benefit from support. Two dyadic studies tested whether perceived movement toward important goals would mediate the effect of recipients' locomotion motivation on positive outcomes in support contexts. In Study 1, couples completed a 10‐day diary and then recalled support interactions with their partner after the …
Creativity and romantic passion
Romantic passion typically declines over time, but a downward trajectory is not inevitable. Across 3 studies (1 of which encompassed 2 substudies), we investigated whether creativity helps bolster romantic passion in established relationships. Studies 1A and 1B revealed that people with highly creative personalities report not only greater overall passion but also an attenuation in the tendency for passion to decline as relationship duration incr…
Does Michelangelo care about age? An adult life-span perspective on the Michelangelo phenomenon
Humans are motivated to expand their actual self toward an ideal self. Known as the Michelangelo phenomenon, movement toward the ideal self can be facilitated through an affirming romantic partner and is linked to positive life outcomes. Yet, research on the Michelangelo phenomenon has primarily focused on young adult samples, and it remains unknown whether the framework generalizes across the adult life span. The authors addressed this shortcomi…
Revising Working Models Across Time: Relationship Situations That Enhance Attachment Security
We propose the Attachment Security Enhancement Model (ASEM) to suggest how romantic relationships can promote chronic attachment security. One part of the ASEM examines partner responses that protect relationships from the erosive effects of immediate insecurity, but such responses may not necessarily address underlying insecurities in a person’s mental models. Therefore, a second part of the ASEM examines relationship situations that foster more…
Me or Us? Self-Control Promotes a Healthy Balance Between Personal and Relationship Concerns
Although romantic partners strive to achieve an optimal balance in fulfilling both personal and relational concerns, they are inevitably challenged by how much time and effort they can dedicate to both concerns. In the present work, we examined the role of self-control in successfully maintaining personal–relational balance through promoting balance and preventing personal and relational imbalance (overdedication to personal or relational concern…
Self-determined self-other overlap: Interacting effects on partners’ perceptions of support and well-being in close relationships
Filling the Void: Bolstering Attachment Security in Committed Relationships
Attachment security has many salutary effects in adulthood, yet little is known about the specific interpersonal processes that increase attachment security over time. Using data from 134 romantically committed couples in a longitudinal study, we examined trust (whether a partner is perceived as available and dependable) and perceived goal validation (whether a partner is perceived as encouraging one’s personal goal pursuits). In concurrent analy…
Are minority status children's cross‐ethnic friendships beneficial in a multiethnic context
Past research has demonstrated the negative impact of perceived ethnic discrimination (PED) on psychological well-being among children. Given research demonstrating the benefits of cross-ethnic friendship for children's intergroup attitudes, we examined whether cross-ethnic friendships would attenuate the effects of PED on well-being and resilience within a multi-ethnic context. Two hundred and forty-seven South Asian British children (M = 11 yea…
The Manhattan effect: When relationship commitment fails to promote support for partners’ interests
Research on close relationships has frequently contrasted one's own interests with the interests of the partner or the relationship and has tended to view the partner's and the relationship's interests as inherently aligned. The present article demonstrated that relationship commitment typically causes people to support their partner's personal interests but that this effect gets weaker to the extent that those interests misalign or even threaten…
Cross-ethnic friendships: Are they really rare? Evidence from secondary schools around London
Trust and biased memory of transgressions in romantic relationships
Relative to people with low trust in their romantic partner, people with high trust tend to expect that their partner will act in accordance with their interests. Consequently, we suggest, they have the luxury of remembering the past in a way that prioritizes relationship dependence over self-protection. In particular, they tend to exhibit relationship-promoting memory biases regarding transgressions the partner had enacted in the past. In contra…
The soothing effects of forgiveness on victims' and perpetrators' blood pressure
A laboratory experiment tested whether conciliatory behavior predicts lower blood pressure following spouses' discussion of a recent marital transgression. Sixty‐eight married couples discussed unresolved transgressions—with random assignment determining whether the husband or the wife was in the victim role—and then rated victim and perpetrator conciliatory behavior (with the former akin to forgiveness and the latter akin to amends) while watchi…
Caryl Rusbult: The Epitome of the Michelangelo Phenomenon in Action
The doormat effect: When forgiving erodes self-respect and self-concept clarity
We build on principles from interdependence theory and evolutionary psychology to propose that forgiving bolsters one's self-respect and self-concept clarity if the perpetrator has acted in a manner that signals that the victim will be safe and valued in a continued relationship with the perpetrator but that forgiving diminishes one's self-respect and self-concept clarity if the perpetrator has not. Study 1 employed a longitudinal design to demon…
The part of me that you bring out: Ideal similarity and the Michelangelo phenomenon
This work examines the Michelangelo phenomenon, an interpersonal model of the means by which people move closer to (vs. further from) their ideal selves. The authors propose that partner similarity--similarity to the ideal self, in particular--plays an important role in this process. Across 4 studies employing diverse designs and measurement techniques, they observed consistent evidence that when partners possess key elements of one another's ide…
Navigating personal and relational concerns: The quest for equilibrium
The authors' personal-relational equilibrium model suggests that people come to seek equilibrium in their dedication to personal and relational concerns in that these 2 important needs cannot always be gratified simultaneously. The authors proposed that the experience of personal-relational disequilibrium motivates attempts to restore equilibrium and that achieving equilibrium promotes life satisfaction. Four studies revealed good support for the…
To think or to do: The impact of assessment and locomotion orientation on the Michelangelo phenomenon
This work examines how individual differences in assessment and locomotion shape goal pursuits in ongoing relationships. The Michelangelo phenomenon describes the role that close partners play in affirming versus disaffirming one another's pursuit of the ideal self. Using data from a longitudinal study of ideal goal pursuits among newly committed couples, we examined whether the action orientation that characterizes locomotion creates an optimal …
Executive Self, Self-Esteem, and Negative Affectivity: Relations at the Phenotypic and Genotypic Level
Complementary approaches examined the relations among executive self, self-esteem, and negative affectivity. A cross-sectional (N = 4,242) and a longitudinal (N = 158) study established that self-esteem mediated the relation between executive self and negative affectivity. A 3rd study (N = 878 twin pairs) replicated this pattern and examined genetic and environmental influences underlying all 3 phenotypes. Covariation among the 3 phenotypes refle…
Are normal narcissists psychologically healthy: Self-esteem matters
Five studies established that normal narcissism is correlated with good psychological health. Specifically, narcissism is (a) inversely related to daily sadness and dispositional depression, (b) inversely related to daily and dispositional loneliness, (c) positively related to daily and dispositional subjective well-being as well as couple well-being, (d) inversely related to daily anxiety, and (e) inversely related to dispositional neuroticism. …
Dealing with betrayal in close relationships: Does commitment promote forgiveness
This work complements existing research regarding the forgiveness process by highlighting the role of commitment in motivating forgiveness. On the basis of an interdependence-theoretic analysis, the authors suggest that (a) victims' self-oriented reactions to betrayal are antithetical to forgiveness, favoring impulses such as grudge and vengeance, and (b) forgiveness rests on prorelationship motivation, one cause of which is strong commitment. A …

Self‐Respect and Pro‐Relationship Behavior in Marital Relationships
This work advances an interdependence theoretic analysis of the role of self‐respect in ongoing close relationships. Self‐respect is defined as the tendency to perceive the self as a principled person who is worthy of honor and high regard and is argued to rest on moral integrity. Consistent with predictions, results from a study of marital relationships revealed that individual self‐respect is positively associated with both the individual's and…
