Divorce in the kibbutz: Affective responses to separation

This article is part of a comprehensive research project in which the central characteristics of the process of divorce in the kibbutz were examined. It appears that the framework of the kibbutz, free as it is from socio-economic pressures and boundary factors not directly connected with the marital relationship as such, provides an excellent and perhaps unique opportunity to investigate the pure emotional effects of the marital breakup.     

Genetic Counseling, Reproductive Behavior and Future Reproductive Intentions of People with Neurofibromatosis Type 1 (NF1)

Neurofibromatosis type 1(NF1) is a complex and variable inherited disorder. The complexity and variability present particular difficulty for genetic counseling. Thirty-three people with NF1 of reproductive age were interviewed about their experience of genetic counseling, their past reproductive behavior and future intentions. One third reported having had no genetic counseling or not having it until after their first child. In part, this may be due to delay in diagnosis but also indicates poor access to genetic services. Only three people had ever been offered prenatal genetic testing and only one had accepted. Although testing is still technically difficult, the greatest deterrent to uptake of prenatal testing for NF1 is the variability of the disorder. However, six of the 17 people planning future pregnancies would want a test with a view to termination if necessary. Others would welcome testing in order to be prepared but not to terminate. We discuss some of the factors which influence reproductive decision making for people with NF1 and some of the difficulties in genetic counseling in such a variable and complex disorder.     

Adolescent Gang Membership and Differences in Ethnic Identity,Esteem, and Efficacy

Scholars have long recognized the impacts of gang membership on adolescents. While some have focused primarily on the negative effects, this seeks to understand the nuanced reasoning and results of joining a gang explicitly on the youth’s perceptions of self-esteem, efficacy, and identity. Using the longitudinal assessment of the Gang Resistance Education and Training (GREAT) program, propensity score matching was conducted on four attitudinal measures to determine whether positive outcomes were seen among adolescents reporting one-time gang involvement. Results indicate a positive effect on self-identity measures. Discussion of these findings illustrates the need for future research and policy implications.     

Bilingual enhancements have no socioeconomic boundaries

To understand how socioeconomic status (SES) and bilingualism simultaneously operate on cognitive and sensory function, we examined executive control, language skills, and neural processing of sound in adolescents who differed in language experience (i.e. English monolingual or Spanish‐English bilingual) and level of maternal education (a proxy for SES). We hypothesized that experience communicating in two languages provides an enriched linguistic environment that can bolster neural precision in subcortical auditory processing which, in turn, enhances cognitive and linguistic function, regardless of the adolescent's socioeconomic standing. Consistent with this, we report that adolescent bilinguals of both low and high SES demonstrate more stable neural responses, stronger phonemic decoding skills, and heightened executive control, relative to their monolingual peers. These results support the argument that bilingualism can bolster cognitive and neural function in low‐SES children and suggest that strengthened neural response consistency provides a biological mechanism through which these enhancements occur.     

The role of rhythm in perceiving speech in noise: a comparison of percussionists,vocalists and non-musicians

The natural rhythms of speech help a listener follow what is being said, especially in noisy conditions. There is increasing evidence for links between rhythm abilities and language skills; however, the role of rhythm-related expertise in perceiving speech in noise is unknown. The present study assesses musical competence (rhythmic and melodic discrimination), speech-in-noise perception and auditory working memory in young adult percussionists, vocalists and non-musicians. Outcomes reveal that better ability to discriminate rhythms is associated with better sentence-in-noise (but not words-in-noise) perception across all participants. These outcomes suggest that sensitivity to rhythm helps a listener understand unfolding speech patterns in degraded listening conditions, and that observations of a “musician advantage” for speech-in-noise perception may be mediated in part by superior rhythm skills.

Effect of MAO A deficiency on different kinds of aggression and social investigation in mice

Monoamine oxidase A (MAO A) degrades serotonin, dopamine and noradrenaline, factors critically involved in the regulation of aggression. Different kinds of aggression were investigated in Tg8, a transgenic mouse strain lacking a functional MAO A gene. MAO A-deficient mice differ from wild-type C3H/HeJ (C3H) in terms of showing higher territorial, predatory and isolation-induced aggression. Tg8 demonstrated shorter latencies to cricket killing and to the first attack after 6 weeks isolation than C3H mice. In the resident-intruder paradigm, MAO A-lacking mice were more aggressive than C3H when tested as intruders. In contrast to C3H, attack in Tg8 mice did not depend on different aggressiveness of intruders of BALB/c, A/Sn and C3H strains. Tg8 mice displayed no increase in aggression but demonstrated reduced social investigation towards anesthetized, as well as towards juvenile BALB/c males. Thus, MAO A deficiency in Tg8 mice is accompanied by increased expression of different kinds of aggression, as well as by disruption of normal pattern of social interaction.     

Role of 5HT1A receptors in a variety of kinds of aggressive behavior in wild rats and counterparts selected for low defensiveness towards man

The 5HT_1A receptor agonist ipsapirone (10 mg/kg) suppressed shock-induced aggression in wild and domesticated rats but did not affect predatory aggression in either group of animals. Ipsapirone decreased neophobia and inhibited defensive reactions by wild rats towards man in the glove test. [³H]8-OH-DPAT binding, which labels 5HT_1A receptors, was significantly increased in the hypothalamus of domesticated rats in comparison with wild counterparts, while 5HT_1A density was unchanged in the frontal cortex in domesticated animals. In essence, the aggressive reactions contributing to the defensive behavior complex in wild rats appear to be regulated through 5HT_1A receptors. © 1992 Wiley-Liss, Inc.     

CHILDHOOD SEXUAL ABUSE, CULTURE, AND COPING: A QUALITATIVE STUDY OF LATINAS

The purpose of this study was to articulate a model of how Latinas cope with childhood sexual abuse (CSA) and the ways in which personal and cultural variables influence their coping strategies. Nine women who identified as Latina and as survivors of CSA participated in an in-depth interview. The data were analyzed using a grounded theory methodology. Results suggested that participants' coping efforts were influenced by a variety of cultural factors and that they engaged in a wide range of coping behaviors, all of which served two main functions: (1) seeking relief from negative emotions and (2) protecting one's self from further abuse.     

Multimodal Treatments for Childhood Attention-deficit/Hyperactivity Disorder: Interpreting Outcomes in the Context of Study Designs

The goal of this article was to outline issues critical to evaluating the literature on incremental benefit of multiple effective treatments used together, vs. a single effective treatment, for childhood ADHD. These issues include: (1) sequencing and dosage of treatments being combined and compared; (2) difficulty drawing valid conclusions about individual components of treatment when treatment packages are employed; (3) differing results emerging from measurement tools that purportedly measure the same domain; and (4) the resultant difficulty in reaching a summary conclusion when multiple outcome measures yielding conflicting results are used. The implications of these issues for the design and conduct of future studies are discussed, and recommendations are made for future research.
