Self-expansion perceptions and behaviors uniquely contribute to relationship quality over time.

Self-expansion refers to the process of broadening the self via engaging in novel activities, gaining new skills, and acquiring new perspectives and is proposed to be driven in large part by one's close relationships. Self-expansion experiences include perceptions of potential (i.e.

Are you tired of "us?" Accuracy and bias in couples' perceptions of relational boredom.

Relational boredom is an important cognitive-emotional experience that is understudied in the relationship maintenance literature. In three dyadic studies, we investigated accuracy and bias in partners' perceptions of each other's relational boredom, and how accurate and biased boredom perceptions were associated with relationship quality. Results revealed that, overall, partners tended to overestimate-but accurately track-each other's relational boredom across the features that comprise relational boredom and across time.

Perceptual Accuracy for Sexual Rejection in Romantic Relationships.

In the current research, we investigated perceptual accuracy in romantic partners' detection of sexual rejection. In two daily diary studies of predominantly cisgender heterosexual couples, we examined patterns of accuracy and bias concerning both the degree of sexual disinterest (Study 1; N = 98 couples) and occurrence of sexual rejection (Study 2; N = 115 couples), as well as how these perceptions were associated with satisfaction. Using a multi-method approach to capture both continuous and categorical operationalizations of sexual rejection (Study 1: truth and bias; Study 2: quasi-signal detection), we found that people were both accurate and biased in their perceptions of partner rejection.

The detriments of unmet sexual ideals and buffering effect of sexual communal strength.

Despite the importance of sex for the maintenance of satisfying romantic relationships, our understanding of a person's sexual ideals-the traits and attributes a person desires in a sexual partner or experience-and what might buffer against lower satisfaction associated with unmet sexual ideals is limited. Across four studies including cross-sectional, dyadic, longitudinal, and experimental methods (N = 1,532), we draw on the Ideal Standards Model and theories of communal motivation to examine whether unmet sexual ideals are associated with lower sexual satisfaction and relationship quality and test whether higher sexual communal strength-the motivation to meet a partner's sexual needs-buffered these effects. Across studies, when individuals perceived their partner to fall short in meeting their sexual ideals, they reported poorer sexual and relationship quality.
