Expanding Who I Am: Validating the Self-Expansion Preference Scale.

People's self-concepts are subject to change through various processes, one of which is self-expansion. Self-expansion is a motivation to increase one's self-concept through engaging in novel, exciting, and interesting activities or by taking on one's partner's qualities. Despite the plethora of research on self-expansion, there has not been much work on whether people vary in their desire to expand. This study validates a new measure, called the Self-Expansion Preference Scale, to examine people's differing motivation for self-expansion. The sample included 611 participants who responded to 24 items, 12 of which pertained to self-expansion, a desire to increase the self-concept, and 12 of which pertained to self-conservation, a desire to maintain the self-concept. After reverse coding the 12 conserver items, an exploratory and confirmatory factor analysis indicated that there was a single dominant factor of self-expansion. The single-factor scale positively correlated with a series of both convergent measures (e.g., openness to experience) and predictive measures (e.g., hedonic well-being). Ultimately, the Self-Expansion Preference Scale offers new insight into a well-established process in an easily administered format. Looking forward, it would be interesting to see the implications of the scale as applied to romantic relationships, where self-expansion was initially researched.

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.

Hungry for love: the influence of self-regulation on infidelity.

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.

Princesses, Princes, and Superheroes: Children's Gender Cognitions and Fictional Characters.

The goal of the present study was to identify whether children recognize the gender stereotypes prevalent within the increasingly popular princess, prince, and superhero characters. Interviews with 126 children from the northeast region of the Unites States (3-11 years old) indicated that children recognized the gender-typed personality traits of princesses, princes, and superheroes, with older children holding more gender-typed cognitions about the characters. Children's own-schemas (i.e., beliefs that apply to themselves) and superordinate schemas (i.e., include beliefs about others' preferences and behaviors) for the characters were mostly gender typed and congruent. Older children gender-typed princesses as for girls more than younger children, whereas older children considered superheroes to be for boys and girls more than younger children did. Older children also considered the characters to be for them less, potentially reducing the negative implications of exposure to gender-typed messages associated with the characters. Individual differences exist in children's perceptions of these fictional characters, with children's own androgyny being positively correlated with their perceptions of princesses' androgyny levels. Further, girls were more flexible in their stereotyping of princesses, noting they were "for girls and boys" more. The authors discuss the results' practical and theoretical implications.

Something's missing: need fulfillment and self-expansion as predictors of susceptibility to infidelity.

The present authors investigated whether an individual's motivations that are related to need fulfillment and self-expansion within a romantic relationship can predict self-reported susceptibility to infidelity. A sample of 109 college students (50 men, 59 women) who were in dating relationships completed questionnaires that assessed 5 types of variables of need fulfillment (i.e., intimacy, companionship, sex, security, and emotional involvement), 3 types of self-expansion variables (i.e., self-expansion, inclusion of the other in the self, and potential for self-expansion), and susceptibility to infidelity. As the present authors predicted, both sets of predictors (need fulfillment and self-expansion) significantly contributed to the variance in susceptibility to infidelity. The present findings indicated the possibility that, when a relationship is not able to fulfill needs or provide ample self-expansion for an individual, his or her susceptibility to infidelity increases.
