Ethnic identity and reconciliation: two main tasks for the young in Bosnia-Herzegovina

The saliency of ethnicity and ethnic identity is influenced by contextual circumstances. In Bosnia-Herzegovina, due to the current ethno-political situation, ethnicity and ethnic identity most likely are important aspects of adolescents' lives. The main purpose of this study is to describe a group of young Mostarians in relation to ethnic identity and reconciliation. Focus is on the participants' perspectives on these subjects and the meanings they attribute to the concepts. A total of 89 young Mostarians are included in the study. A third of the participants are members of a local peace- and reconciliation-building organization, Koraci Nade. Results show that ethnic identity is highly salient for the group. While participants demonstrate strong emotional attachment to their ethnic group, exploration of ethnic identity is less reported. With regard to reconciliation, the participants perceive it as very desirable and show a personal and integrated relation to the concept. However, their definitions of the concept are vague as to what constitutes the process of reconciliation. Although of great importance to the members, participation in the peace-building organization was not found to enhance either ethnic identity or cross-ethnic friendships.     

Adult social behavioral effects of heavy adolescent marijuana use among African Americans

The authors examined the effects of heavy adolescent marijuana use on employment, marriage, and family formation and tested both dropping out of high school and adult marijuana use as potential mediators of these associations among a community sample of African Americans followed longitudinally from age 6 to age 32-33. They used propensity score matching to reduce selection bias when estimating the effects of heavy adolescent marijuana use. Logistic regression results on the sample matched on sex, and early demographic and behavioral variables showed that adolescent marijuana use has adult social behavioral consequences: Use of marijuana 20 times or more during adolescence was associated with being unemployed and unmarried in young adulthood and having children outside of marriage for both males and females. Dropping out of high school and more frequent adult marijuana use seem to be important parts of the pathway from adolescent marijuana use to negative life outcomes.     

Tactile spatial acuity differs between fingers: a study comparing two testing paradigms

Tactile spatial acuity (TSA) is a reliable and reproducible measure of somatosensory system function that has been used to study abroad range of subject populations. Although TSA is most often assessed at the fingertip, published studies employing identical stimuli disagree on whether TSA differs between the fingers of neurologically normal subjects. Using a validated grating orientation discrimination task, we determined TSA bilaterally at the index and ring fingers of 16 healthy young adults. Motivated by earlier work, we utilized two stimulus presentation paradigms, the method of constant stimuli (MCS) and a staircase (SC) method. We found that TSA was significantly higher (the discrimination threshold was lower) at the index than at the ring finger, which was consistent with a prior study. Although mean thresholds at both fingers were higher when measured with the SC than with the MCS paradigm, this difference did not reach statistical significance (p = .14). These findings should facilitate both design and interpretation of future studies investigating TSA.     

Ultimate, provisional, and personal meaning of life: differences and common ground

Building on Viktor Frankl's clinical approach of Logotherapy and the works of subsequent theoreticians, three types of meaning of life were theoretically derived and empirically investigated, Ultimate, Provisional, and Personal meaning. These types were characterized, first, by the amount of agreement of subjects, second, by sources of Life Meaning, which were assessed by content analyses, third, by correlations, and fourth by prediction with ratings of important life concepts from the domains of Well-being, Religiosity, and Prosocial Behavior. 192 German adults, 45 men and 147 women, whose M age was 31.6 yr. (SD = 11.9), participated. Analysis indicated different sources for the Ultimate meaning compared with the other meaning types, which seem to display more similarities with each other. Other important life concepts, such as Belief, Harmony, Happiness, and Human Goodness were related to the investigated types of meaning of life. Some implications for clinical applications, research perspectives, and Positive Psychology are discussed.     

Neighborhood Poverty, Social Capital, and the Cognitive Development of African American Preschoolers

In this investigation, we examine the impact of the ecological context of the residential neighborhood on the cognitive development of children by considering social processes not only at the family-level but also at the neighborhood-level. In a socioeconomically diverse sample of 200 African American children living in 39 neighborhoods in Baltimore, we found that neighborhood poverty was associated with poorer problem-solving skills over and above the influence of family economic resources and level of positive parent involvement. Sampson has theorized that neighborhood poverty affects child well-being by altering levels of neighborhood social capital as well as family social capital. Although we found that indicators of neighborhood and family social capital were associated with cognitive skills, these factors did not explain the association between neighborhood poverty and problem-solving ability. Implications for future research in the area of neighborhoods and child development are discussed.     

On the Edge of Diversity: Bringing African Americans and Latinos Together in a Neighborhood Group

This article describes challenges we encountered when organizing a group of African Americans and Latinos in a community where ethnic tensions had been normative. We relate how the first author, a Caucasian with a university affiliation, entered this diverse community and employed ethnographic methods in an attempt to understand it. The ethnography provides a context for the principal challenge we encountered: ensuring that the group had ethnic balance. Focusing on the group's first meeting, we describe the uncertainty of whether our work would be helpful or harmful to the community. We conclude with reflections on the gaps between science and practice in diverse communities; the utility and limits of ethnography; the multiple ecological levels of influence on the community; dilemmas around a White male taking proactive stances while trying to empower a group consisting mostly of women of color; and the influence of values we brought to the community.     

When phonology fails: orthographic neighbourhood effects in dyslexia

Both cerebral hemispheres contain phonological, orthographic and semantic representations of words, however there are between-hemisphere differences in the relative engagement and specialization of the different representations. Taking orthographic processing for example, previous studies suggest that orthographic neighbourhood size (N) has facilitatory effects in the right but not the left hemispheres. To pursue the nature of this asymmetric N effect, in particular whether there are individual differences in such specialisation, we examined N in a case of developmental dyslexia, FM. We first describe the nature of his difficulties, which are mainly severe phonological deficits. Employing the divided visual field paradigm with FM revealed a greater sensitivity in the right than in the left hemisphere to orthographic variables, with a significant inhibitory N effect in the left, but not right hemisphere. Such inhibition, to a lesser degree, was found among a group of adults with dyslexia but not among age-matched normal readers. We argue that enhanced sensitivity to orthographic cues is developed in some cases of dyslexia when a normal, phonology-based left hemisphere word recognition processing is not achieved. The interpretation presented here is cast in terms of differences between people with dyslexia and typical readers that originate in the atypical way in which orthographic representations are initially set up.     

Trait aggressiveness and situational provocation: a test of the traits as situational sensitivities (TASS) model

In this article, the authors propose and test an interactionist model of personality functioning. The model maintains that many traits function in a threshold-like manner, such that less situational strength is needed to evoke a trait-relevant response in people who are high on the trait than in those who are low on the trait. Because of these different sensitivities, people who are high on a trait are more reactive to moderate provocation than are those who are low on a trait, but the opposite is true when strong provocation is compared to moderate provocation. Three studies are reported showing how the model can be used to understand the nature of aggression.     

ASSESSING MEDIATED MODELS OF FAMILY CHANGE IN RESPONSE TO INFANT HOME VISITING: A TWO-PHASE LONGITUDINAL ANALYSIS

The objective of this study was to assess whether a mediated model of change could account for the long-term effects of infant home-visiting services observed at ages 5 and 7 years in a high-risk cohort. Participants were 41 mothers and infants from low-income families who were referred to parent-infant home-visiting services during the first 9 months of life due to concerns about the caretaking environment. Services ended when infants reached 18 months of age. Families received between 0 and 18 months of weekly home visits based on infant age of entry into the study. During childhood (ages 5 and 7 years), teachers rated children's behavior problems using standardized instruments. Early home-visiting services accounted for positive child outcomes at 18 months, 5 years, and 7 years of age; however, earlier positive outcomes related to intervention did not account for intervention-related effects at later ages. Further inspection of the data revealed that two additional principles, one of escalating morbidity among less intensively served groups and one of generalized family problem-solving skills, were needed to account for the pattern of effects over time. We conclude that the "domino models" assessed by mediational analyses may be too simple to capture the intervention-related change processes occurring in high-risk cohorts over time.
