Personalized Neural Networks Underlie Individual Differences in Ethnic Identity Exploration and Resolution

This study examined how ethnic identity relates to large-scale brain networks implicated in social interactions, social cognition, self-definition, and cognitive control. Group Iterative Multiple Model Estimation (GIMME) was used to create sparse, person-specific networks among the default mode and frontoparietal resting-state networks in a diverse sample of 104 youths aged 17–21. Links between neural density (i.e., number of connections within and between these networks) and ethnic identity exploration and resolution were evaluated in the full sample. Ethnic identity resolution was positively related to frontoparietal network density, suggesting that having clarity about one’s ethnic group membership is associated with brain network organization reflecting cognitive control. These findings help fill a critical knowledge gap about the neural underpinnings of ethnic identity.     

Six‐Month‐Olds' Detection of Clauses Embedded in Continuous Speech: Effects of Prosodic Well‐Formedness

Three experiments investigated the role of prosodic structure for infants' recognition of embedded word sequences. Six‐month‐olds were familiarized with 2 versions of the same sequence, 1 corresponding to a well‐formed prosodic unit and the other to a prosodically ill‐formed sequence (although a successive word series). Next, infants heard 2 test passages. One included the well‐formed unit, and the other included the ill‐formed sequence. In Experiment 1, infants listened longer to the passage containing the well‐formed unit, suggesting that such units, even when they are embedded, are better recognized. Experiments 2 and 3 showed that this better recognition does not depend on an acoustic match between the familiarized sequences and their later embeddings. This suggests that the advantage of the well‐formed unit is at least partially due to infants' use of prosody to parse continuous speech.     

Do the Kids Think They're Okay? Adolescents' Views on the Impact of Marriage and Divorce

A sample (N?=?365) of middle school and high school students from both divorced and intact families were surveyed with regard to their opinions about the impact of their parents' relationships (divorced or married) on a variety of areas of their lives. Adolescents from separated or divorced (S/D) families tended to rate their parents' relationships and impact on them more negatively than adolescents from living together or married (L/M) families. However, both groups consistently rated their parents in the same direction on a variety of topics. Gender was not a factor in the responses of either group. However, age (middle school vs. high school) was related to significant differences in adolescents' views about parents.     

Engaging the Process of Transformation

The contributions included in this issue demonstrate the variety of ways in which participatory and interpretive methods are transforming the field of psychology and clarify the integration of the personal and political commitments of the authors within their research. A number of issues remain to be negotiated, however, before these methods take their full place in the field. This conclusion considers a few of these issues, including an examination of how these approaches demand a fundamental reassessment of validity in psychological research. It also considers the critical issue of the ownership of knowledge, and proposes a reframing of the ethical guidelines for research in the field. Finally, it invites further discussion and debate around the issues raised in this issue.     

The Evolution of Organizations: Suggestions from Complexity Theory About the Interplay Between Natural Selection and Adaptation

There has been much debate in the managementliterature between neo-Darwinists (who believe in thenatural selection of populations of organizations) andadaptationists (who contend that changes in organization structure and behavior occur in response to theenvironment). The general thesis of neo-Darwinism isthat species are blindly selected for survival by theenvironment. The latest empirical support for the dominant neo-Darwinism perspective adopted bymost biologists is based primarily on the experimentsconducted by Salvador Luria who claims to haveconclusively demonstrated that genes mutate randomly.Recently, however, biologists have re-examined Luria sresearch methods and, after replications of hisexperiments, now question some aspects of the validityof his results. Moreover, there is now new researchwhich provides support for the earlier adaptationistposition, namely, the existence of evolutionary driversand directors existing within self-organizing systems.Of particular importance to the present study is the experimental indication thatself-organizing systems play a conscious role in theirown evolution. We propose that similar mechanisms orprocesses operate in organizational adaptation, thuspointing toward a theoretical modification ofneo-Darwinism that embraces both adaptation and naturalselection in a general, unified theory.     

Men’s Aggression Toward Women: A 10‐Year Panel Study

The present study examined the longitudinal course of men’s physical and psychological aggression toward a partner across 10 years, using a community sample of young couples (N = 194) from at‐risk backgrounds. Findings indicated that men’s aggression decreased over time and that women’s antisocial behavior and depressive symptoms predicted changes in men’s aggression. This suggests the importance of studying social processes within the dyad to have a better understanding of men’s aggression toward a partner.     

Dyadic Adjustment and Community Involvement in Same-Sex Couples

This study examines the effects of age and involvement in the gay, lesbian, and bisexual community on dyadic adjustment in 62 male and 54 female same-sex couples. Participants completed the Dyadic Adjustment Scale (Spanier, 1976) and scales of political and social involvement in the gay, lesbian, and bisexual community based on Peplau and Cochran (1981). Those in midlife (35 years and older) had significantly lower conflict in matters of affection and sex than those younger (less than 35 years old). Political involvement interacted significantly with gender and age in predicting dyadic consensus scores: Among younger women, greater political involvement was associated with higher dyadic consensus. Inter-partner differences in social involvement were significantly associated with greater dyadic conflict in sex and affection. Inter-partner dyadic adjustment and community involvement scores were positively correlated, in general. Findings support the importance of age in the study of same-sex couples. The implications for conceptualizations of the gay, lesbian, and bisexual communities and dyadic adjustment are discussed.
