What Do People Do, Say, and Feel When They Have Affairs? Associations between Extradyadic Infidelity Motives with Behavioral, Emotional, and Sexual Outcomes.

In this study, we surveyed a sample of U.S. undergraduates and internet-based participants (N = 495) about their experiences during/after romantic infidelity (affairs), and their initial motivations to engage in infidelity. Meaningful associations emerged between motivation and experience variables. Dyadic motivations (e.g., anger at one's partner, lack of love) were linked with longer affairs, more public dates with affair partners, and primary relationship dissolution. Conversely, non-dyadic situational motivations (e.g., feeling stressed or intoxicated) were linked with shorter affairs, less satisfying sex during affairs, and lower rates of disclosure and dissolution. These findings suggest meaningful infidelity typologies and may aid researchers and practitioners in helping others resolve relational conflicts.

Manipulation of Self-Expansion Alters Responses to Attractive Alternative Partners.

Past behavioral research has examined relationship infidelity as a potential outcome of focusing on attractive alternative partners when already in a relationship. The extent to which individuals find such alternatives attractive has been shown to be associated with various factors in the relationship, including self-expansion. However, no previous research has tested the role of self-expansion experimentally. This paper presents two experiments that directly manipulate self-expansion to determine the effect of self-expansion on responses to attractive alternative partners. Participants primed to experience a higher need for self-expansion had better memory for attractive alternatives with self-expanding traits dissimilar to their partner's versus attractive alternatives with self-expanding traits similar to their partner's. Additionally, participants primed with self-expansion (via a video of their partner discussing ways in which life with one another is exciting, novel, and challenging), had less fMRI BOLD response to attractive alternatives of the opposite sex in regions associated with perception of attractive faces (anterior cingulate and medial prefrontal cortex) relative to when they were primed with love (via a video of their partner discussing times they felt strong feelings of love for one another), or neutral content (via a video of their partner discussing some times in which they engage in mundane, routine activities together). The magnitude of this effect in the ACC correlated with relationship closeness as measured by the inclusion of the other in the self scale.

Motivations for Extradyadic Infidelity Revisited.

Relationship infidelities are motivated by many distinct factors, with previous research indicating motivations of dissatisfaction, neglect, anger, and sexual desire (Barta & Kiene, 2005). We expand on this by demonstrating additional, empirically distinct motivations for infidelity. Using an Internet-based questionnaire, participants (N = 495), most of whom were young adults, self-reported their infidelities. In addition to evidence for previously studied motivations, our data demonstrate additional factors, including lack of love ("I had 'fallen out of love with' my primary partner"), low commitment ("I was not very committed to my primary partner"), esteem ("I wanted to enhance my popularity"), gaining sexual variety ("I wanted a greater variety of sexual partners"), and situational factors ("I was drunk and not thinking clearly"). Our results also show personality correlates with infidelity motivations. Consistent with predictions, attachment insecurity was associated with motivations of anger, lack of love, neglect, low commitment, and esteem, while unrestricted sociosexual orientation was associated with sexual variety. Implicit beliefs (e.g., growth, destiny, romanticism) were differentially associated with sexual desire, low commitment, lack of love, and neglect. These findings highlight multifaceted motivations underlying infidelity, moving beyond relationship deficit models of infidelity, with implications for research and psychotherapy involving people's romantic and sexual relationships.

The longitudinal course of thought disorder in geriatric patients with chronic schizophrenia.

OBJECTIVE: This study longitudinally assessed previously validated dimensions of thought disorder--verbal underproductivity and disconnection--in geriatric schizophrenia and replicated previous cross-sectional differences in communication disorders. METHOD: Two hundred twenty patients with chronic schizophrenia were assessed with the Thought, Language, and Communication Scale over a mean follow-up period of 2.3 years. RESULTS: Patients had increases in verbal underproductivity but stable scores on disconnection over the follow-up period. Worsening in verbal underproductivity was associated with concurrent worsening in Mini-Mental State Examination scores and older age at baseline. CONCLUSIONS: Verbal underproductivity worsens with aging and is associated with cognitive worsening, although disconnected speech is relatively stable. Some geriatric patients with schizophrenia may lose the skills necessary to report symptoms, leading to the impression that their clinical status is improving.
