Traumatic brain injury (TBI) represents a major public health problem, which is associated with neurological dysfunction. In severe or moderate cases of TBI, in addition to its high mortality rate, subjects may encounter diverse behavioral dysfunctions. Previous reports suggest that an association between TBI and chronic pain syndromes tends to be more common in patients with mild forms of brain injury. Despite causing minimal brain damage, mild TBI (mTBI) often leads to persistent psychologically debilitating symptoms, which can include anxiety, various forms of memory and learning deficits, and depression...

Background and aims The "Internet addiction" paradigm has been criticized for several shortcomings, including inattention to specific online behaviors, not distinguishing the Internet from other media, insufficient focus on comorbidities, and definitions that do not take into account the constant access now possible. The paradigm's biggest casualty, however, may be that it has diverted attention away from subtle personality changes that seem to occur online, including in users who cannot be considered "addicted" under any definition...

René Hurlemann, Nina Marsh
Unlike any other species, humans frequently engage in altruistic behaviors by which they increase another individual's welfare even if this implies personal costs. The psychological motives underlying altruistic behaviors remain diverse, ranging from the ability to reciprocate trust and cooperation to bonding and empathizing with family members or even genetically unrelated others. This article explores the neuroendocrine architecture of altruism by emphasizing the crucial role of the evolutionarily highly conserved peptide hormone oxytocin as a modulator of cooperative behaviors including empathy-driven altruism...

The present short-term longitudinal study examined prospective associations between two forms of peer victimization (i.e., physical, relational) and both externalizing and internalizing problems in early childhood. The study assessed 97 children (42 girls; M age = 45.22 months, SD = 6.99) over the course of one school year with assessments occurring at the end of each semester (approximately 6 months apart). Multiple methods were used to collect data over the course of one school year to test theoretically driven hypotheses...

Few studies have investigated the relationship between post-natal inflammatory biomarkers at early age and child neurodevelopment outcomes. The main aim of this study was to examine the relationship between IL-6, IL-1β, IL-4 cytokines, as well as cortisol at 6 and 12months of age, and neurodevelopment and psychological problems at 30months of age. The study was conducted on a sample of 51 full-term newborns who were followed up at 6, 12, and 30months of age. Infant neurodevelopment was assessed using the Bayley Scales of Infant Development-II, psychological problems were assessed with the Child Behavior Checklist 1...

Behavioral and psychological symptoms of dementia (BPSD) occur in up to 80% of AD patients and represent one of the largest factors contributing to caregiver burden. To analyze the effect of galantamine on BPSD and caregiver burden, we treated a total of 50 patients with mild AD for 12 weeks and evaluated them using the Neuropsychiatric Inventory (NPI) and Japanese version of the Zarit Caregiver Burden Interview (ZBI). We also performed regional cerebral blood flow single photon emission computed tomography (rCBF SPECT) at baseline using three-dimensional sterotatic surface projections...

A task force of experts was convened by the American Psychological Association (APA) to update the knowledge and policy about the impact of violent video game use on potential adverse outcomes. This APA Task Force on Media Violence examined the existing literature, including the meta-analyses in the field, since the last APA report on media violence in 2005. Because the most recent meta-analyses were published in 2010 and reflected work through 2009, the task force conducted a search of the published studies from 2009-2013...

BACKGROUND AND OBJECTIVES: Psychological symptoms can be associated with celiac disease; however, this association has not been studied prospectively in a pediatric cohort. We examined mother report of psychological functioning in children persistently positive for tissue transglutaminase autoantibodies (tTGA), defined as celiac disease autoimmunity (CDA), compared with children without CDA in a screening population of genetically at-risk children. We also investigated differences in psychological symptoms based on mothers' awareness of their child's CDA status...

BACKGROUND: Bullying is a major problem worldwide and Chile is no exception. Bullying is defined as a systematic aggressive behavior against a victim who cannot defend him or herself. Victims suffer social isolation and psychological maladjustment, while bullies have a higher risk for conduct problems and substance use disorders. These problems appear to last over time. The KiVa antibullying program has been evaluated in Finland and other European countries, showing preventive effects on victimization and self-reported bullying...

REVIEW
Christopher J Ferguson, Eugene Beresin
For nearly half a century, psychologists, pediatricians and psychiatrists have studied the potential impact of media violence on aggression and societal violence, particularly among youth. Despite hundreds of studies, scholars have failed to find consensus on potential effects. Nonetheless, professional organizations such as the American Academy of Pediatrics and American Psychological Association have released policy statements conclusively linking violent media to societal concerns. In reaction, some scholars have accused these professional groups of distorting evidence and failing to inform the public of the inconsistent nature of studies in this field...

Behavioral observation techniques which relate action to personality have long been neglected (Furr and Funder in Handbook of research methods in personality psychology, The Guilford Press, New York, 2007) and, when employed, often use human judges to code behavior. In the current study we used an alternative to human coding (biomechanical research techniques) to investigate how personality traits are manifest in gait. We used motion capture technology to record 29 participants walking on a treadmill at their natural speed...

Although cases of child abuse among migrant families are often reported by social media, the issue of child maltreatment among migrant families in China has received little empirical attention. This study investigated both the prevalence of child maltreatment by parents among migrant families, and the individual, family and community-level risk factors associated with child abuse in this context. A survey was conducted with 667 migrant and 496 local adolescents in Shenzhen, South China, with a stratified two-stage cluster sampling design...

Some children who bully others are also victimized themselves ("bully-victims") whereas others are not victimized themselves ("bullies"). These subgroups have been shown to differ in their social functioning as early as in kindergarten. What is less clear are the motives that underlie the bullying behavior of young bullies and bully-victims. The present study examined whether bullies have proactive motives for aggression and anticipate to feel happy after victimizing others, whereas bully-victims have reactive motives for aggression, poor theory of mind skills, and attribute hostile intent to others...

Aggression in mental health units is a significant and pervasive problem. However, the characteristics of patients associated with increased aggression propensity remain unclear and there are few attempts to expand understanding of these characteristics by drawing upon contemporary aggression theory. This study assessed the influence of interpersonal (hostile-dominance) and personality (psychopathy), General Aggression Model-specified (aggressive script rehearsal, attitudes towards violence, and trait anger), and clinical (psychiatric symptoms) factors on aggression during psychiatric hospitalization in 200 inpatients (132 men and 68 women; 19-64 years, M=38...

This research examined the overtime reciprocal relations between maternal and paternal harsh discipline and children's externalizing behavior. Seven hundred two father-mother dyads of children (6-9 years of age at baseline) completed measures of parental harsh discipline and children's externalizing behavior at five time points, 1 year apart. Autoregressive latent trajectory models revealed that maternal and paternal corporal punishment predicted subsequent children's externalizing behavior (parent-driven effects), whereas children's externalizing behavior predicted subsequent maternal and paternal psychological aggression (child-driven effects)...

This study examined individual behavioral predictors of help-seeking using the frameworks of the Andersen model and thetheory of planned behavior in a sample of help-seeking female survivors of intimate partner violence (IPV). In-person interviews were conducted with 372 women (<em>M</em><sub>age</sub> = 34.41 years, 66% African American). Results indicated that variables suggested by the Andersen model, including age, depression, psychological aggression, and posttraumatic stress-related arousal symptoms, were significant predictors of help-seeking...

Bonnie J Leadbeater, Paweena Sukhawathanakul, Brett Holfeld, Jeffery R Temple
Past research suggests that exposure to parent psychological control and peer relational aggression and victimization experienced during adolescence is associated with relational intimate partner violence (IPV) in young adults (ages 22 to 29). However, the effects of continuities in these concerns across young adulthood have not been assessed. Relational IPV is characterized by behaviors intended to damage partner's emotional well-being and security in a romantic relationship (e.g., threatening to break up, purposefully ignoring, or causing jealousy)...

Facial expressions are important for humans in communicating emotions to the conspecifics and enhancing interpersonal understanding. Many muscles producing facial expressions in humans are also found in domestic dogs, but little is known about how humans perceive dog facial expressions, and which psychological factors influence people's perceptions. Here, we asked 34 observers to rate the valence, arousal, and the six basic emotions (happiness, sadness, surprise, disgust, fear, and anger/aggressiveness) from images of human and dog faces with Pleasant, Neutral and Threatening expressions...

BACKGROUND: Agitation in patients with dementia increases caretaker burden, increases healthcare costs, and worsens the patient's quality of life. Antipsychotic medications, commonly used for the treatment of agitation in patients with dementia have a box warning from the FDA for elevated mortality risk. Electroconvulsive therapy (ECT) has made significant advances over the past several years, and is efficacious in treating a wide range of psychiatric conditions. We provide a systematic review of published literature regarding the efficacy of ECT for the treatment of agitation in patients with dementia (major neurocognitive disorder)...

The microaggression concept has recently galvanized public discussion and spread to numerous college campuses and businesses. I argue that the microaggression research program (MRP) rests on five core premises, namely, that microaggressions (1) are operationalized with sufficient clarity and consensus to afford rigorous scientific investigation; (2) are interpreted negatively by most or all minority group members; (3) reflect implicitly prejudicial and implicitly aggressive motives; (4) can be validly assessed using only respondents' subjective reports; and (5) exert an adverse impact on recipients' mental health...
