Exposure to maternal vs. paternal partner violence,PTSD, and aggression in adolescent girls and boys

Adolescents who witness interparental violence (IPV) are at increased risk for perpetrating aggressive acts. They are also at risk for post‐traumatic stress disorder (PTSD). In this study, we examined the relation between exposure to maternal vs. paternal physical IPV and adolescent girls' and boys' aggressive behavior toward mothers, fathers, friends, and romantic partners. We also assessed the influence of PTSD (as assessed by the Diagnostic Interview for Children and Adolescents‐IV (DICA‐IV)) on the relation between exposure to IPV and aggressive behavior. Participants were 63 girls and 49 boys, ages 13–18, consecutively admitted to a youth correctional facility or assessment facility designated to serve aggressive and delinquent youth. Structural equation modeling was used to estimate unique relations between exposure to maternal vs. paternal IPV and youth aggression in relationships. Girls who observed their mothers' aggressive behavior toward partners were significantly more aggressive toward friends. Similarly, boys who witnessed their fathers' aggression were significantly more aggressive toward friends. Adolescent girls and boys who observed aggression by mothers toward partners reported significantly higher levels of aggression toward their romantic partners. Approximately one third of our sample met PTSD criteria; the relation between exposure to parental IPV and aggression was stronger for individuals who met criteria for PTSD. The implications of understanding the relations between parents' and their daughters' and sons' use of aggression are discussed within the context of providing support for families in breaking intergenerational patterns of violence and aggression.

Selective attention to the parts of an object

Recent empirical results suggest that there is a decrement in dividing attention between two objects in a scene compared with focusing attention on a single object. However, objects can be made of individual parts. Is there a decrement for dividing attention across different parts of a single object? We addressed this question in two experiments. In Experiment 1, we demonstrated that attention can exhibit part-based selection—that is, the subjects were more accurate in reporting two attributes from the same part of an object than they were in reporting attributes from different parts of an object. In Experiment 2, we demonstrated that part-based attentional decrements occurred simultaneously with object-based attentional decrements. The results from Experiment 2 demonstrated that part-based attention is evident at the same time as objects are processed as coherent wholes. Our results imply that there is an attentional mechanism that can select either objects or their parts.     

Expertise in tactile pattern recognition

This article explores expertise in tactile object recognition. In one study, participants were trained to differing degrees of accuracy on tactile identification of two-dimensional patterns. Recognition of these patterns, of inverted versions of these patterns, and of subparts of these patterns was then tested. The inversion effect (better recognition of upright than inverted patterns) and the part-whole effect (better recognition of the whole than a part pattern), traditionally considered signatures of visual expertise, were observed for tactile experts but not for novices. In a second study, participants were trained as visual or tactile experts and then tested in the trained and nontrained modalities. Whereas expertise effects were observed in the modality of training, cross-modal transfer was asymmetric; visual experts showed generalization to haptic recognition, but tactile experts did not show generalization to visual recognition. Tactile expertise is not obviously attributable to visual mediation and emerges from domain-general principles that operate independently of modality.     

Of mice and men: virtual Hebb-Williams mazes permit comparison of spatial learning across species

We developed a computer-generated virtual environment to test humans, for the first time, on the Hebb-Williams mazes. The goal was to provide a standardized test that could be used to directly compare human performance with that of C57BL/6J mice performing in real versions of the mazes. Such a comparison seems crucial if conclusions regarding genetic manipulations of rodents are to be mapped onto human cognitive disorders. The learning curves across species were strikingly similar, lending support to the rodent model of human spatial memory. Humans learned faster than rodents in both the acquisition and the test portions of the protocol, and females of both species were less efficient in solving these problems than males. These results represent the first modern comparison of human and rodent learning that uses the same test of spatial problem solving.     

Object width modulates object-based attentional selection

Visual input typically includes a myriad of objects, some of which are selected for further processing. While these objects vary in shape and size, most evidence supporting object-based guidance of attention is drawn from paradigms employing two identical objects. Importantly, object size is a readily perceived stimulus dimension, and whether it modulates the distribution of attention remains an open question. Across four experiments, the size of the objects in the display was manipulated in a modified version of the two-rectangle paradigm. In Experiment 1, two identical parallel rectangles of two sizes (thin or thick) were presented. Experiments 2–4 employed identical trapezoids (each having a thin and thick end), inverted in orientation. In the experiments, one end of an object was cued and participants performed either a T/L discrimination or a simple target-detection task. Combined results show that, in addition to the standard object-based attentional advantage, there was a further attentional benefit for processing information contained in the thick versus thin end of objects. Additionally, eye-tracking measures demonstrated increased saccade precision towards thick object ends, suggesting that Fitts’s Law may play a role in object-based attentional shifts. Taken together, these results suggest that object-based attentional selection is modulated by object width.     

EARLY REGULATION IN CHILDREN WHO ARE LATER DIAGNOSED WITH AUTISM SPECTRUM DISORDER. A LONGITUDINAL STUDY WITHIN THE DANISH NATIONAL BIRTH COHORT

Studies have shown that children later diagnosed with autism spectrum disorders (ASD) in their first years of life might show symptoms in main developmental areas and that these signs might be sensed by the parents. The present study investigated in a large birth cohort if children later diagnosed with ASD had deviations at 6 and 18 months in areas such as the ability to self‐regulate emotions, feeding, and sleeping. The study was based on prospective information collected from 76,322 mothers who participated in the Danish National Birth Cohort. When the children reached an average age of 11 years, 973 children with ASD and a control group of 300 children with intellectual disability (IDnoASD) were identified via Danish health registries. Associations were found between short periods of breast‐feeding and the children later diagnosed with ASD and IDnoASD as well as associations at 18 months to deviations in regulation of emotions and activity. The similarities in these associations emphasize how difficult it is to distinguish between diagnoses early in life.     

Can children break the cycle of disadvantage? Structure and agency in the transmission of education across generations

Research has shown that parents tend to pass educational advantage or disadvantage on to their children. However, little is known about the extent to which the intergenerational transmission of education involves children’s agency. In this study we drew from two traditions in sociological and social psychological theorizing—the theory of cultural and social reproduction and the theory of human agency—to examine whether agency influences children’s educational performance, and if so, whether this influence can be observed among children across social classes. We used data from the Spanish sample of the Program for International Student Assessment (N = 25,003 15-year-olds). Results indicate that the level of child agency was weakly positively related to social class, that child agency impacted on a child’s educational performance, and that the positive effect of agency on educational performance did not vary by social class. This suggests that strategies to enhance disadvantaged children’s agency may prove useful in reducing social gradients in educational performance. More generally, our findings may ignite a debate about the role that social structure and human agency play in shaping social inequality and mobility.     

A latent variable modeling approach to identifying subtypes of serious and violent female juvenile offenders

Females have recently become an important population in research related to serious and violent juvenile offending. Although a small body of research exists on girls in the deep end of the system, very few studies have examined the degree of heterogeneity within high-risk female samples. This study applied latent class analysis (LCA) to identify subgroups of female juvenile offenders based on their self-report of offending profiles (N=133). Results supported a three-class solution with subgroups characterized by patterns of 'violent and delinquent', 'delinquency only', and 'low' offending patterns. The LCA solution was replicated in an independent sample of high-risk females. The 'violent and delinquent' class was characterized by significantly higher rates of DSM-IV diagnoses for internalizing disorders, affect dysregulation, exposure to violence (within the home, school and neighborhood), and familial histories of criminality. Implications for future research, policy and clinical practice are discussed.     

The relation of psychopathy to concurrent aggression and antisocial behavior in high-risk adolescent girls and boys

The present study examined the concurrent relationship between psychopathy characteristics as measured by the PCL:YV and aggressive and antisocial behavior in a sample of 142 high-risk adolescent girls and boys. The unique relationship between each of three PCL:YV factors (Arrogant and Deceitful Interpersonal Style, Deficient Affective Experience, and Impulsive and Irresponsible Behavioral Style) and outcomes was evaluated to determine which aspects of psychopathy are most crucially linked to aggressive and antisocial behavior in adolescents. Dependent measures were expanded to include both relational and physical forms of aggression to better capture meaningful outcomes for girls and boys. Regression analyses showed that the relationships between psychopathic features and outcomes were equivalent for boys and girls, and that deficits in affect were most consistently associated with aggression. These findings are concordant with the well established finding in developmental research showing that deficits in empathy and affect regulation are associated with aggression.     

COVID-19 Interconnectedness: Health Inequity,the Climate Crisis,and Collective Trauma

The COVID-19 pandemic brings to the forefront the complex interconnected dilemmas of globalization, health equity, economic security, environmental justice, and collective trauma, severely impacting the marginalized and people of color in the United States. This lack of access to and the quality of healthcare, affordable housing, and lack of financial resources also continue to have a more significant impact on documented and undocumented immigrants. This paper aims at examining these critical issues and developing a framework for family therapists to address these challenges by focusing on four interrelated dimensions: cultural values, social determinants of health, collective trauma, and the ethical and moral responsibility of family therapists. Given the fact that family therapists may unwittingly function as the best ally of an economic and political system that perpetuates institutionalized racism and class discrimination, we need to utilize a set of principles, values, and practices that are not just palliative or after the fact but bring forth into the psychotherapeutic and policy work a politics of care. Therefore, a strong call to promote and advocate for the broader continuum of health and critical thinking preparing professionals to meet the challenges of health equity, as well as economic and environmental justice, is needed. The issues discussed in this paper are specific to the United States despite their relevance to family therapy as a field. We are mindful not to generalize the United States' reality to the rest of the world, recognizing that issues discussed in this paper could potentially contribute to international discourse.
