Health Implications of Conflict in Close Relationships

We summarize the large body of research conducted over the previous 30 years on the link between interpersonal conflict and physiological outcomes, with a focus on implications for health. Specifically, we review evidence that conflict in close, romantic relationships affects internal bodily processes, including cardiovascular, endocrine, and immune function, as well as objective health indicators. We focus on studies that have utilized standardized, laboratory‐based conflict discussions, as we believe this methodology provides the clearest picture of how conflict affects health. It is our hope that this general overview serves as a useful introduction to the state of the field.     

A hit-and-miss investigation of asymmetries in wheelchair navigation

In contrast to the leftward inattention caused by right parietal damage, normal brain function shows a subtle neglect of the right and left sides in peripersonal and extrapersonal space, respectively. This study explored how these attentional biases cause healthy individuals to collide with objects on the right. In Experiment 1, participants navigated manual and electric wheelchairs through a narrow doorway. More rightward collisions were observed for the electric, but not the manual, wheelchair. Experiment 2 demonstrated that the rightward deviation for electric wheelchairs increased for wider doorways. Experiment 3 established that the rightward deviation is not the result of task-related vestibular input, using a remote control device to operate the wheelchair. The rightward deviation persisted in Experiment 4 when the doorway was removed, suggesting that the bias is the result of a mis-bisection of space. In Experiment 5, the rightward bias was replicated using an electric scooter, which is steered using handlebars. Finally, Experiment 6 required participants to point to the middle of the doorway, using a laser, before moving the scooter. Rightward mis-bisection was observed in both conditions. Rightward mis-bisection of lines in extrapersonal space provides the most parsimonious explanation of the rightward collisions and deviations.     

The Evolution of Psychological Testing at the Austen Riggs Center: A Theoretical Analysis

Theoretical perspectives on personality and the development of psychopathology have shifted markedly over the last 7 decades. However, it remains unclear how those changes affect mental health practice. Comprehensive and conscientiously recorded reports of psychological testing provide a clear window on this process because they comprise distinctive records of how patients are assessed and understood. For this study, we conducted an exploratory, qualitative analysis of the narratives of the testing reports over the past 65 years at the Austen Riggs Center, a private psychiatric hospital and residential treatment center, to assess changes over time and to evaluate the influence that various factors had on the reports. The data revealed significant changes in psychologists' ways of assessing and conceptualizing personality and identity, adaptive functioning, and psychological development. Additionally, we evaluated how the evolving theoretical influences, such as institutional, professional, and sociohistorical factors affected the psychologist's model of psychopathology and development. This study raises important questions about how theoretical innovations affect clinical practice over time.     

Benchmarking Treatment Effectiveness of Community‐Delivered Trauma‐Focused Cognitive Behavioral Therapy

It is critical for urban youth with post‐traumatic stress disorder (PTSD) living in poverty to have access to evidence‐based interventions for their traumatic stress. However, there is limited research on the effectiveness of these interventions when provided in urban, community settings. The objectives of the current study are to (a) evaluate the effectiveness of trauma‐focused cognitive behavioral therapy delivered from 2013 to 2016 in 15 behavioral health agencies on youth (N = 114) PTSD as well as  general mental health symptoms and  functioning, and (b) benchmark these clinical outcomes against other published efficacy and effectiveness trials. Effectiveness data are from the Philadelphia County Community Behavioral Health System, a system that has invested significantly in the training and ongoing support of clinicians providing high‐quality trauma services to youth since 2012. From baseline to last assessment, youth PTSD symptom severity (d = 0.34), PTSD functional impairment (d = 0.38), and overall mental health problem severity (d = 0.29) improved. The effect sizes of  improvements were smaller than effect sizes observed in efficacy and effectiveness studies. This study is the first benchmarking study of TF‐CBT and provides preliminary findings with regard to the effectiveness, and transportability, of TF‐CBT to urban community settings that serve youth in poverty.     

Development of brain functional connectivity and its relation to infant sustained attention in the first year of life

The study of brain functional connectivity is crucial to understanding the neural mechanisms underlying the improved behavioral performance and amplified ERP responses observed during infant sustained attention. Previous investigations on the development of functional brain connectivity during infancy are primarily confined to the use of functional and structural MRI techniques. The current study examined the relation between infant sustained attention and brain functional connectivity and their development during infancy with high‐density EEG recordings. Fifty‐nine infants were tested at 6 (N = 15), 8 (N =14), 10 (N = 17), and 12 (N = 13) months. Infant sustained attention was defined by measuring infant heart rate changes during infants’ looking. Functional connectivity was estimated from the electrodes on the scalp and with reconstructed cortical source activities in brain regions. It was found that infant sustained attention was accompanied by attenuated functional connectivity in the dorsal attention and default mode networks in the alpha band. Graph theory analyses showed that there was an increase in path length and a decrease in clustering coefficient during infant sustained attention. The functional connectivity within the visual, somatosensory, dorsal attention, and ventral attention networks and graph theory measures of path length and clustering coefficient were found to increase with age. These findings suggest that infant sustained attention is accompanied by distinct patterns of brain functional connectivity. The current findings also suggest the rapid development of functional connectivity in brain networks during infancy.     

The gender paradigm in domestic violence research and theory: Part 1—The conflict of theory and data

Feminist theory of intimate violence is critically reviewed in the light of data from numerous incidence studies reporting levels of violence by female perpetrators higher than those reported for males, particularly in younger age samples. A critical analysis of the methodology of these studies is made with particular reference to the Conflict Tactics Scale developed and utilised by Straus and his colleagues. Results show that the gender disparity in injuries from domestic violence is less than originally portrayed by feminist theory. Studies are also reviewed indicating high levels of unilateral intimate violence by females to both males and females. Males appear to report their own victimization less than females do and to not view female violence against them as a crime. Hence, they differentially under-report being victimized by partners on crime victim surveys. It is concluded that feminist theory is contradicted by these findings and that the call for “qualitative” studies by feminists is really a means of avoiding this conclusion. A case is made for a paradigm having developed amongst family violence activists and researchers that precludes the notion of female violence, trivializes injuries to males and maintains a monolithic view of a complex social problem.     

Spatial awareness, alertness, and ADHD: the re-emergence of unilateral neglect with time-on-task

Studies examining a relationship between attention deficit hyperactivity disorder (ADHD) and relative visual inattention towards left space have produced inconsistent results. Here, based on previous studies with adult neurological patients who show very severe inattention to the left, we examine whether any spatial bias in ADHD may be modulated by changes in alertness levels. In a single case, we found that inattention to the left--that was intermittently apparent--dramatically increased as a function of time-on-task. No significant changes were observed on the right. The implications for clinical assessment and research design are discussed.     

Flexible contrast gain control in the right hemisphere

This study investigates whether the right hemisphere has more flexible contrast gain control settings for the identification of spatial frequency. Right-handed participants identified 1 and 9 cycles per degree sinusoidal gratings presented either to the left visual field-right hemisphere (LVF-RH) or the right visual field-left hemisphere (RVF-LH). When luminance contrast was randomized across a wide range (20-60%), performance gradually improved with contrast in the LVF-RH. Conversely, performance in the RVF-LH was disrupted and saturated for 20 and 60% of contrast, respectively, leading to a LVF-RH advantage for these contrast levels. When contrast was blocked or randomized for a smaller range (30-50%), the LVF-RH advantage was diminished. Flexible contrast gain control is needed when contrast is randomized across a wide range, but not when it is blocked or randomized across a smaller range. The results therefore suggest that the right hemisphere is able to process spatial frequency information across a wider range of contrast levels than is the left hemisphere.     

Gender and psychopathy: an overview of important issues and introduction to the special issue

One of the most important concepts to ever emerge in forensic psychology and law is psychopathy. It would be difficult to exaggerate the profound effect the construct has had on research and practice in correctional psychology, psychiatry, and criminology. Much less pronounced has been an interest in understanding the potential relevance and practical implications that this personality disorder might have for providing insights into antisocial behaviors and crimes committed by girls and women. In this paper we provide an overview of some of the pressing issues confronting clinicians and researchers and provide an introduction to this special issue dedicated to gender and psychopathy.
