Unfolding Relations among Mindful Parenting,Recurrent Conflict,and Adolescents’ Externalizing and Internalizing Problems

The current study examined unfolding relations among mothers’ mindful parenting, parent–adolescent recurrent conflict, and adolescents’ externalizing and internalizing problems. In a community sample of 117 families (31% black, Asian, American Indian, or Latino), parents and adolescents (52% female; average age = 12.13 years) were followed over 15 months. Parents answered questions about mindful parenting and recurrent conflict, and adolescents reported on their own externalizing and internalizing problems. Path analyses indicated that higher levels of mindful parenting were significantly related to lower levels of recurrent conflict 2–3 months later, controlling for previous levels of recurrent conflict. Moreover, lower levels of recurrent conflict were significantly related to lower levels of externalizing problems and internalizing problems 1 year later, controlling for previous levels of those problems. Subgroup analyses indicated that relations were comparable across subgroups defined by adolescent gender, race, parent marital status, and family financial strain. The effects of mindful parenting were robust even after accounting for other indicators of positive and supportive parenting, namely inductive reasoning and warmth in the parent–adolescent relationship. These findings highlight the potential of mindful parenting to improve family interactions and adolescent adjustment.     

Who's Being Served? "Self-Serving" Attributions in Social Hierarchies

Making external attributions for negative events, though often considered “self-serving,” also implies that the attributor is not in control of critical resources. We hypothesized that making external attributions for negative events will lead to impressions of powerlessness. Because individuals in high-status roles are expected to have power and control, external attributions may violate these role expectations; thus, we further hypothesized that status would moderate the relationship between attributions and interpersonal outcomes. Specifically, more negative impressions and affect will be directed toward high-status individuals who make external attributions than toward their lower status counterparts. Three studies were conducted, one using a role-play methodology, one using an experimentally created hierarchy, and one using vignettes. The results supported our hypotheses: external attributions can be highly disserving for people in high-status positions.     

Processing variant forms in spoken word recognition: the role of variant frequency

Recognition of a spoken word phonological variant--schwa vowel deletion (e.g., corporate --> corp'rate)--was investigated in vowel detection (absent/present) and syllable number judgment (two or three syllables) tasks. Variant frequency corpus analyses (Patterson, LoCasto, & Connine, 2003) were used to select words with either high or low schwa vowel deletion rates. Speech continua were created for each word in which schwa vowel length was manipulated (unambiguous schwa-present and schwa-absent endpoints, along with intermediate ambiguous tokens). Matched control nonwords were created with identical schwa vowel continua and surrounding segments. The low-deletion-rate words showed more three-syllable judgments than did the high-deletion-rate words. Matched control nonwords did not differ as a function of deletion rate. Experiments 2 and 3 showed a lexical decision reaction time advantage for more frequent surface forms, as compared with infrequent ones, for schwa-deleted (Experiment 2) and schwa-present (Experiment 3) stimuli. The results are discussed in terms of representations of variant forms of words based on variant frequency.     

Women of the “Sandwich” Generation and Multiple Roles: The Case of Russian Immigrants of the 1990s in Israel

It has been suggested that adding elder care tothe list of women's multiple roles may significantlyjeopardize their well-being and mental health. Thisstudy explored the experiences with multiple roles among Jewish women who immigrated to Israelfrom the former Soviet Union in the early 1990s withtheir extended families. The thirty informants for thestudy (aged between 35 and 55) represented a variety of pre-emigration backgrounds. Their commondenominator was in multiple roles (employment andcaregiving to both children and ageing parents) coupledwith the challenges of resettlement in a country swept by the mass influx of immigrants. Facingdownward social mobility, marital distress, and problemswith adolescent children, the women of thissandwich generation also had to supporttheir uprooted parents. The growing dependency and declininghealth of the elders significantly burdened the womenand hindered their occupational upgrading and socialintegration in Israel. Exhaustion and tight time budgets led to somatization and poor self-careamong middle-aged women. Social services' role in eldercare was minimal. The informants' social networks weremainly co-ethnic, and their coping tools drew on Israeli-Russian subculture. The studyconcludes that, even in the relatively egalitarianRussian-Soviet gender system, women function asprincipal caregivers, often at the expense of other lifegoals.     

Effect of chronic ethanol administration on intermale aggression in rats

An experiment was performed to study the effect of chronic ethanol administration on intermale aggression in rats using a 24-hour resident-intruder test. During the resident-intruder test residents displayed virtually all of the agonistic behaviors, and intruders displayed virtually all of the defensive behaviors. Intruders treated with ethanol displayed more defensive behavior and elicited more agonistic behavior than control intruders. Twenty minutes into the resident-intruder test intruders showed the greatest increase in corticosterone (338% vs. 129%), while residents showed the greatest increase in testosterone (103% vs. 18%). On the 2nd day of the resident-intruder test intruders lost more weight than residents (21.5 g vs. 10.2 g). Plasma corticosterone levels remained elevated for the intruders, and in particular for those intruders displaying defensive behaviors regardless of the resident's behavior. Plasma testosterone levels remained elevated for those residents that were paired with intruders that displayed defensive behaviors regardless of the resident's behavior. The frequency and severity of biting attacks by ethanol residents was significantly greater than that of control residents. In addition, the locus of biting attack shifted from the upper back of intruders paired with control residents to the flanks, tail, lower feet, and ventral surface on intruders paired with ethanol residents.     

Are Individuals Always Aware of Their Trauma-Related Intrusive Thoughts? A Study of Meta-Awareness

Individuals are not always aware of their mental content. We tested whether lack of awareness occurs in those who have experienced trauma, with and without posttraumatic stress disorder (PTSD). We also examined the role of proposed cognitive mechanisms (working memory and inhibition) in explaining unnoticed intrusions. Individuals with PTSD (n = 44), and varying levels of symptoms (high posttraumatic stress [PTS]: n = 24; low PTS: n = 37) reported on intrusive thoughts throughout a reading task. Intermittently, participants responded to probes about whether their thoughts were trauma related. Participants were “caught” engaging in unreported trauma-related thoughts (unnoticed intrusions) for between 24 and 27% of the probes in the PTSD and high PTS groups, compared with 15% of occasions in the low PTS group. For trauma-related intrusions only, participants lacked meta-awareness for almost 40% of probes in the PTSD group, which was significantly less than that observed in the other groups (～60%). Contrary to predictions, working memory and response inhibition did not predict unnoticed intrusions. The results suggest that individuals who have experienced significant trauma can lack awareness about the frequency of their trauma-related thoughts. Further research is warranted to identify the mechanisms underpinning the occurrence of unnoticed intrusions.     

Learn locally, think globally. Exemplar variability supports higher-order generalization and word learning

Research suggests that variability of exemplars supports successful object categorization; however, the scope of variability's support at the level of higher-order generalization remains unexplored. Using a longitudinal study, we examined the role of exemplar variability in first- and second-order generalization in the context of nominal-category learning at an early age. Sixteen 18-month-old children were taught 12 categories. Half of the children were taught with sets of highly similar exemplars; the other half were taught with sets of dissimilar, variable exemplars. Participants' learning and generalization of trained labels and their development of more general word-learning biases were tested. All children were found to have learned labels for trained exemplars, but children trained with variable exemplars generalized to novel exemplars of these categories, developed a discriminating word-learning bias generalizing labels of novel solid objects by shape and labels of nonsolid objects by material, and accelerated in vocabulary acquisition. These findings demonstrate that object variability leads to better abstraction of individual and global category organization, which increases learning outside the laboratory.
