Exploring interhemispheric collaboration in older compared to younger adults

Physical and Name Identity letter-matching tasks were used to explore differences in interhemispheric collaboration in younger and older adults. To determine whether other factors might also be related to across/within-hemisphere processing or visual field asymmetries, neuropsychological tests measuring frontal/executive functioning were administered, and comparisons were made for participants split into low and high efficiency groups based on performance on the letter-matching tasks. A Task by Across/Within interaction was found for both groups, but with a stronger within-hemisphere advantage for the Physical Task and a weaker across-hemisphere advantage for the Name Task for older participants. More efficient groups and better performers on several neuropsychological tasks showed a reduced across-hemisphere advantage for the Name Identity task. Findings suggest that computational complexity, specific task demands, and perhaps trade-offs between age-related changes in gray and white matter all contribute to whether processing loads are distributed across or within hemispheres as we age.     

Immigration, suicidal ideation and deliberate self-injury in the Boston youth survey 2006

The prevalence and immigration-related correlates of deliberate self-injury (DSI) and suicidal ideation (SI) were estimated in a sample of Boston public high school students in 2006. Compared with U.S.-born youth, immigrant youth were not at increased risk for DSI or SI, even if they had experienced discrimination due to their ancestry. By contrast, U.S.-born youth who reported having been discriminated against because of their ancestry had an increased risk of deliberate self-injury (odds ratio [OR] = 3.1, 95% confidence interval [CI] = 1.6-5.9) and suicidal ideation (OR = 2.1, 95% CI = 1.2-3.8). The combination of being U.S.-born and experiencing ancestry-based discrimination identifies youth at increased risk for suicidal behavior.     

Families, Gender Relations and Social Change in Brazil: Practices, Discourse, Policy

We discuss three different areas in which policies on gender and the family have been debated and formulated in Brazil, revealing both the forces of change and the many contradictions that are at work within this society today. After a brief look at the historical vicissitudes of families and family life in Brazil, as representations and as forms of social organization, we come to our more immediate context: the re-democratization processes that engulfed Brazilian society as of the 1980s and the social actors generated therein. Issues relating to gender and sexuality become increasingly visible on the broad political agenda that, notwithstanding national specificities, also converges with social, political and cultural trends emerging all over the world in the latter decades of the twentieth century. The three specific issues we discuss here—the Maria da Penha Law on domestic violence, efforts regarding the legalization of abortion and recent debates that have emerged around a bill introduced to give legal status to same-sex relationships—provide testimony of a society characterized by tensions between mechanisms sustaining restrictive definitions of family, linked to male dominance, heterosexism and hierarchical gender roles, and those that push toward more egalitarian, diverse and democratic family relations.     

The role of intersensory redundancy in the emergence of social referencing in 5½-month-old infants

Early evidence of social referencing was examined in 5?-month-old infants. Infants were habituated to 2 films of moving toys, one toy eliciting a woman's positive emotional expression and the other eliciting a negative expression under conditions of bimodal (audiovisual) or unimodal visual (silent) speech. It was predicted that intersensory redundancy provided by audiovisual (but not available in unimodal visual) events would enhance detection of the relation between emotional expressions and the corresponding toy. Consistent with predictions, only infants who received bimodal, audiovisual events detected a change in the affect-object relations, showing increased looking during a switch test in which the toy-affect pairing was reversed. Moreover, in a subsequent live preference test, they preferentially touched the 3-dimensional toy previously paired with the positive expression. These findings suggest social referencing emerges by 5? months in the context of intersensory redundancy provided by dynamic multimodal stimulation and that even 5?-month-old infants demonstrate preferences for 3-dimensional objects on the basis of affective information depicted in videotaped events.     

Studying Children’s Religious Knowledge: Contributions of Ethnography and the Clinical-Critical Method

We analyze different methodological and conceptual contributions of anthropology and psychogenetic theory to the research of children’s religious knowledge. We argue that for the study of children’s points of view it is possible to build an approach that links aspects studied by both disciplinary fields. With this aim, we revise some of their basic theoretical assumptions and recent reviews as well as their methodological proposals. Then we review the core characteristics of ethnography and the clinical–critical method—proposed by Piaget’s psychogenetic theory—with the goal of stressing their potentialities as well as their limitations in research. We argue that within an ethnographic approach, we must establish certain restrictions on the clinical–critical method following basic premises of social anthropology. This approach lets us demonstrate the importance of understanding children’s constructions by placing them within social relations that children produce and update in everyday interactions.     

A Comparison Between Comprehensive System and an Early Version of the Rorschach Performance Assessment System Administration With Outpatient Children and Adolescents

For many years, the effects of variability in the length of Rorschach records has been debated, and a new administration procedure aimed at reducing the proportion of short and long records has recently been introduced. Using an outpatient sample of children and adolescents, this study explored the impact of an early version of the Rorschach Performance Assessment System (R–PAS) administration, on the central tendencies of Rorschach variables. Specifically, the mean values of 51 variables in 142 Comprehensive System versus 99 R–PAS collected records were compared with each other. Results found comparable mean values across CS and R–PAS administration methods for the variables that guide interpretation with children and adolescents. Both methods produced a comparable number of long (> 27 responses) records. The only relevant difference that emerged is that the early R–PAS administration version yielded significantly fewer short (14–16 responses) records and lower variability in the number of responses.     

Simultaneous masking in a dichotic emotion detection task

The present study investigated the possible role of ceiling effects in producing laterality effects of small magnitude in dichotic emotion detection. Twenty two right-handed undergraduate students participated in the present experiment. They were required to detect the presence of a target emotion in the expressions tones of happiness, sadness, anger, and neutrality presented dichotically. Stimuli were adjusted to 70 dB and occurred simultaneously with a white noise mask that had an intensity of 65, 70, 80, or 85 dB. Results showed a left ear advantage (LEA) for the 65 dB mask and a right ear advantage for the 85 dB mask, but only after two testing sessions. The possible existence of a generalized right ear bias that might affect the observed LEA for non-verbal tasks is discussed. Alternative explanations and limitations of the present experiment are also presented.     

Two-, three-, and four-factor PCL-R models in applied sex offender risk assessments

The authors compared 2-, 3-, 4-factor, and 2-factor/4-facet Psychopathy Checklist-Revised (PCL-R) models in a previously unpublished sample of 1,566 adult male sex offenders assessed under applied clinical conditions as part of a comprehensive state-mandated community notification risk assessment procedure. "Testlets" significantly improved the performance of all models. The 3-factor model provided the best fit to the current data, followed by the 2-factor/4-facet model. The 2-factor model was not supported.
