A proximal change experiment testing two communication exercises with intimate partner violent men

This study tests the immediate impact of two interventions for intimate partner violent (IPV) men in affecting behavioral and emotional change during arguments with their partners. Couples with an abusive male partner (N = 100) discussed an area of conflict twice, interrupted by a brief intervention. Men were randomly assigned to receive (a) an editing-out-the-negative skills training, (b) an accepting influence skills training, or (c) a time-out. IPV men in both skills-training conditions showed greater decreases in aggressive feelings than IPV men in the time-out condition based on their self-report and observed affective behavior. Women also reported feeling less aggressive when their husbands were assigned to one of the skills-training conditions as compared to the control (time-out) condition. Results suggest that IPV men can learn to adopt new communication skills and that they do appear to have a positive impact on the emotional tone of their arguments. Clinically, communication skills training may be a useful addition to battering intervention programs, although these skills may need to be taught to both men and women involved in violent relationships.     

Parental criticism and externalizing behavior problems in adolescents: the role of environment and genotype-environment correlation

Genetic factors are important for the association between parental negativity and child problem behavior, but it is not clear whether this is due to passive or evocative genotype-environment correlation (rGE). In this study, we applied the extended children-of-twins model to directly examine the presence of passive and evocative rGE as well as direct environmental effects in the association between parental criticism and adolescent externalizing problem behavior. The cross-sectional data come from the Twin and Offspring Study in Sweden (N = 909 pairs of adult twins) and from the Twin Study of Child and Adolescent Development (N = 915 pairs of twin children). The results revealed that maternal criticism was primarily due to evocative rGE emanating from their adolescent's externalizing behavior. On the other hand, fathers' critical remarks tended to affect adolescent problem behavior in a direct environmental way. This suggests that previously reported differences in caretaking between mothers and fathers also are reflected in differences in why parenting is associated with externalizing behavior in offspring.     

Maternal depressive symptomatology and child behavior: transactional relationship with simultaneous bidirectional coupling

The present study investigated reciprocal relationships between adolescent mothers and their children's well-being through an analysis of the coupling relationship of mothers' depressive symptomatology and children's internalizing and externalizing behaviors. Unlike studies using discrete time analyses, the present study used dynamical systems to model time continuously, which allowed for the study of dynamic, transactional effects between members of each dyad. Findings provided evidence of coupling between maternal depressive symptoms and children's behaviors. The most robust finding was that as maternal depressive symptoms became more or less severe, children's behavior problems increased or decreased in a reciprocal manner. Results from this study extended upon theoretical contributions of such authors as Richters (1997) and Granic and Hollenstein (2003), providing empirical validation from a longitudinal study for understanding the ongoing, dynamic relationships between at-risk mothers and their children.     

Integrated software for analysis and synthesis of voice quality

Voice quality is an important perceptual cue in many disciplines, but knowledge of its nature is limited by a poor understanding of the relevant psychoacoustics. This article (aimed at researchers studying voice, speech, and vocal behavior) describes the UCLA voice synthesizer, software for voice analysis and synthesis designed to test hypotheses about the relationship between acoustic parameters and voice quality perception. The synthesizer provides experimenters with a useful tool for creating and modeling voice signals. In particular, it offers an integrated approach to voice analysis and synthesis and allows easy, precise, spectral-domain manipulations of the harmonic voice source. The synthesizer operates in near real time, using a parsimonious set of acoustic parameters for the voice source and vocal tract that a user can modify to accurately copy the quality of most normal and pathological voices.

The age deficit on photopic counterphase flicker: contrast, spatial frequency, and luminance effects.

This study evaluated the contribution of reduced contrast sensitivity and retinal illuminance to the age-related deficit on the temporal resolution of suprathreshold spatial stimuli. The discrimination of counterphase flicker was measured in optimally refracted young and elderly observers for sinusoidal gratings of three spatial frequencies (1, 4, and 8 cycles per degree) at three contrast levels (0.11, 0.33, and 0.66). Age deficits in flicker discrimination at the two higher contrast levels and at the two lower spatial frequencies were unrelated to observer contrast sensitivity. Flicker discrimination of young observers who carried out the task through .5 ND filters to simulate a two-thirds reduction of retinal illuminance in the older eye, was similar to that of the elderly observers. An age-related reduction in retinal luminance appears to be a major determinant of the age-related spatiotemporal deficit at suprathreshold contrast levels, although neural factors may also be involved.     

Interference effects in the memory for serially presented locations in Clark's nutcrackers, Nucifraga columbiana

The authors tested the spatial memory of serially presented locations in Clark's nutcrackers (Nucifraga columbiana). Birds were serially presented with locations in an open room. The authors buried a seed in a sand-filled cup at each location and then tested nutcrackers for their memory for each location in the list by using the cluster method. For each item in the list, the authors opened a cluster of 6 holes. Accuracy was measured by how many tries were required for the bird to find the correct location within each cluster. In Experiments 1 and 2, the authors presented 2 lists of locations and found evidence for proactive and retroactive interference. Nutcrackers made errors by visiting the interfering list of locations during recovery of the target list. This finding demonstrates that nutcrackers are susceptible to proactive and retroactive interference during the recall of spatial information.     

Motivations and attitudes affecting high school students' choice of foreign language

There are some foreign languages that enjoy great status in the United States, while other foreign languages are rarely represented at the high school level. The present study explored the following questions: Why do students choose to take a particular foreign language? Do students gravitate toward it because it is widely thought to be the easiest language to learn or because they perceive greater career opportunities with proficiency in this particular language, or is it simply because there are more classes offered? As long as foreign language study is elective in high schools and as long as a variety of languages are offered, the answers to these questions will remain important for foreign language educators, especially in schools where the various language programs compete with one another for student enrollments and the programs' ultimate survival.     

The Use of Prospective Versus Retrospective Pretests with Child-Welfare Involved Families

The purpose of the current study is to examine the use of both a prospective and a retrospective pretest in evaluating the impact of the Strengthening Families Program on foster care involved families affected by parental substance abuse. Debate has existed in the literature for over 60 years regarding the use of retrospective pretests in assessing self-reported program impact, with key stakeholders often arguing strongly that, due to response-shift bias, sensitization, and the nature of many human service settings, retrospective pretesting may be more appropriate. However, program evaluators must also incorporate into the evaluation design funding mandates to collect data at specific points in time. In order to mitigate potential pretest-only biases and enhance the evaluation’s rigor, this study sought to address the pretest debate through the use of both a traditional, prospective pretest and a retrospective pretest. Using data provided by 411 caregivers, program effectiveness was measured in the areas of family, child and parent functioning. Statistical significance tests and effect sizes were analyzed to compare traditional prospective pretest to posttest scores and retrospective pretests to posttest scores. Findings indicate that overall, the Strengthening Families Program positively impacted family, child and parent functioning and that there were few differences between testing approaches when testing for statistical significance; however, relative differences between prospective pretests and retrospective pretests appeared more prominent in effect size computations. This research informs the longstanding debate, and suggests that program evaluators consider the advantages and disadvantages of using a retrospective pretest in design planning.     

Gender-Specific Conflicts among Urban African-American Youth: The Roles of Situational Context and Issues of Contention

The literatures on violence among young men and young women have highlighted the importance of situational context. However, few studies have compared disputes that do not result in violence with those that do, and even fewer have been positioned to investigate the role situational context may play across gender in accounting for these outcomes. Drawing on recent scholarship on gender and violence, this research explores the situational contexts of youth conflicts among African-American adolescent boys and girls. Using a large sample of narrative accounts of 153 violent and nonviolent conflicts, we examine how youth describe the issues of contention in their conflicts, how these relate to the situational contexts in which conflicts emerge, and similarities and differences in the antecedents, contexts, and extent of male and female violence.
