The Role of Self-concept Clarity in Relationship Quality

Previous research has linked self-concept clarity to positive outcomes (Campbell et al., 1996), but has not systematically explored its potential positive association with relationship quality. The current set of studies hypothesizes that self-concept clarity will positively correlate with relationship satisfaction and commitment, and that inclusion of other in the self and self-esteem will mediate the association. Study 1 examined correlations between self-report measures from 199 undergraduates, while Study 2 randomly assigned 78 undergraduates to either engage in a self-concept clarity or self-concept confusion manipulation. As hypothesized, in both studies, higher self-concept clarity was associated with higher relationship satisfaction and commitment. Inclusion of other in the self and self-esteem mediated the association between self-concept clarity and relationship quality measures (the only exception was for self-esteem and commitment in Study 1). These results demonstrate how a persons self-concept relates to romantic relationship quality.

An Expanded Self is a More Capable Self: The Association between Self-concept Size and Self-efficacy

The self-expansion model states that an expanded self-concept is associated with an increased sense of self-efficacy. We conducted four studies (three correlational, one experimental) to test this central tenet of the self-expansion model in a non-relational context. Results indicate that self-concept size (Studies 1 and 2) and subjective sense of self-concept (Study 3) were positively associated with greater self-efficacy. In Study 4, individuals who were randomly assigned to physically expand a representation of their self-concept reported greater self-efficacy at resolving potential problems than those who contracted a self-representation or left it unchanged. Taken together, these four studies provide the first empirical evidence that expanded self-concepts lead to greater self-efficacy.

Hungry for Love: The Influence of Self-Regulation on Infidelity

ABSTRACT The current research examines the effect of self-regulation on the likelihood of committing infidelity. Thirty-two college students in exclusive romantic relationships interacted through a private chat room with an opposite-sex confederate. Prior to this interaction, a food-restriction task depleted half the participants of self-control. As predicted, depleted levels of self-regulation increased the likelihood of infidelity. Specifically, depleted participants were more likely to both accept a coffee date from and supply a personal telephone number to the confederate than non-depleted participants. Weakened self-control may be one potential cause for the levels of infidelity occurring in romantic partnerships today.

Workplace Self-Expansion: Implications for Job Satisfaction, Commitment, Self-Concept Clarity, and Self-Esteem Among the Employed and Unemployed

Similar to how individuals in close relationships incorporate aspects of their partner into their self-concept, we suggest that jobs promote self-expansion when they lead people to develop skills and assume new identities. In Study 1, we sampled currently employed individuals, and results show that self-expansion predicts job satisfaction and commitment, even when controlling for salary, tenure, and demographic variables. In Study 2, we examined the impact of losing a self-expanding job by sampling currently unemployed individuals, and results show that losing a self-expanding job results in lower amounts of self-concept clarity and self-esteem.

Promoting positive emotions following relationship dissolution through writing

Past research shows that writing promotes coping following traumatic events, but pays limited attention to the benefits of writing following relationship dissolution. Research also largely overlooks the utility of positively-focused writing following stressful events. A total of 87 currently single participants (25 males, 62 females) who recently experienced relationship dissolution were randomly assigned to one of three writing conditions (negatively-focused, positively-focused, and neutral) to determine writings impact on change in emotions. As hypothesized, participants in the positive writing condition increased in positive emotions from pretest to immediate posttest compared to both the negative writing and neutral writing conditions. There were no differences between conditions in the experience of negative emotions. These findings show how writing can help people cope with relationship dissolution.

Under Pressure: The Effects of Stress on Positive and Negative Relationship Behaviors

This study investigates the effects of acute stress on positive and negative relationship behaviors, specifically assurances and attention to alternatives. A sample of 129 college students were randomly assigned to either a high or low stress condition, then were led to believe they had the opportunity to interact with attractive potential relationship partners and list compliments about their current partner. Results indicated that those in the high stress condition gave their partner fewer assurances and paid more attention to alternatives. These results suggest that when individuals experience acute stress, they may engage in fewer positive relationship behaviors and more behaviors that are potentially harmful to their relationship.

A Comparison of the Multicultural and Colorblind Perspectives on the Intergroup Attitudes of College Students

This investigation examined whether exposure to a multicultural or colorblind orientation influenced social tolerance in racially diverse students. Students were randomly assigned to a colorblind, multicultural, or control ideology. They completed group-specific measures and general measures of diversity. Results indicate that successful anti-bias interventions require focus on the particular level from which intergroup attitudes are being formed. Second, the effectiveness of these opposing theories is a factor of the history of within group socialization practices. Finally, widespread use of these prominent ideologies in different sectors of society poses a threat to social tolerance in more diverse group settings.

Do shared self-expanding activities have to be physically arousing?

Participation in shared self-expanding activities benefits both relationships and the self. However, most studies use tasks that combine self-expansion and arousal within one activity, making it difficult to know what drives the benefits. We tested the distinct effects of self-expansion and arousal in four studies. In Studies 1 and 2, 35 married couples and 106 friend pairs completed experiments manipulating self-expansion and arousal. Self-expansion (and not arousal) predicted relationship and individual outcomes. In Studies 3 and 4, 200 married individuals and 202 individuals thinking of a close friend reported perceptions of self-expansion and arousal during activities. Simultaneous regressions showed self-expansion, controlling (or not controlling) for arousal, predicted relationship, and individual outcomes. Results suggest that self-expansion is central for deriving benefits of shared activities, while arousal does not seem to be necessary.
