A USC study of over 1,000 children on Mauritius found a strong link between malnutrition and aggressive behavior, with malnourished kids showing a 51% increase in violent and antisocial behavior by age 17. Poor nutrition was linked to lower IQ, which in turn led to later antisocial behavior.
A study by Dr. Guy Stecklov and Dr. Joshua Goldstein found a significant increase in road fatalities in Israel following terrorist attacks. The research suggests that people may become more considerate after an attack, only to experience a temporary surge in aggressive behavior that leads to increased accidents
Research found that differential parenting, particularly negative behavior, is linked to child maladjustment and aggressive-disruptive behavior. The study suggests parents should follow a principle of fairness in dealing with their children, but acknowledges that special circumstances require different treatment.
Research links being overweight in kindergarten girls to a higher risk of behavior problems, including externalizing and internalizing issues. Low family income and maternal depression were strong predictors of these problems, contradicting the common belief that childhood obesity leads to behavior issues for both genders.
A recent study found that employees who were allowed to regulate their emotions in response to customer aggression reported lower levels of stress. Employers are advised to provide training in emotional regulation for service representatives to reduce burnout and absenteeism. The researchers also recommended enhancing job autonomy to m...
Researchers found that long-term consumption of high amounts of isoflavones can alter patterns of agonistic and social behavior in primates, including increased aggressive and submissive behavior. The study suggests careful attention must be taken to balance beneficial and potentially adverse effects of soy consumption.
A recent report by the Association for Psychological Science reveals that media violence consistently shows a link to aggressive behavior in children. The short-term exposure to violent media can increase aggression, while long-term exposure can produce lasting increases in aggressive thought patterns and emotions.
A study found that behavioral anger contributes the most to alcohol-related aggression among men and women. Researchers examined healthy social drinkers and found that those with higher behavioral and cognitive anger scores were more likely to exhibit aggressive behavior when intoxicated. The findings suggest that understanding the rel...
A recent study by Dario Maestripieri found that young monkeys reared by a mother other than their own exhibit the aggressive or friendly behavior of their birth mothers, rather than foster mothers. This suggests that inherited behavioral predispositions may play a more important role in shaping social behavior in primates.
A recent study published in the Journal of Developmental and Behavioral Pediatrics suggests that bedwetting may be associated with low socioeconomic status in children. The research found that almost 39% of children with bedwetting problems came from low socioeconomic backgrounds, compared to 23% of non-bedwetters.
Researchers found that Northwestern crows use passive strategies when stealing from relatives and become aggressive when targeting non-relatives. The study, led by Renee Ha and James Ha, observed 55 birds over 2.5 years and found that kinship significantly affects crow behavior.
Researchers found that progesterone receptor knockout mice showed a complete lack of infanticide and exhibited active paternal care, frequently contacting and retrieving pups. In contrast, control mice committed 74% infanticide and displayed less paternal behavior.
Researchers have identified a genetic basis for aggression and anger, with the vasopressin 1b receptor playing a key role. The study found that mice without this receptor exhibit reduced aggression and impaired social recognition, suggesting potential therapeutic targets for treating aggressive behavior.
A new study by Penn scientists has found that women's brains have a larger volume of orbital frontal cortex, a region involved in modulating aggression, compared to men. This difference may contribute to the perception of women being less aggressive than men.
Researchers at Rockefeller University have found that mice engineered to lack specific genes linked to pheromone detection exhibit reduced aggression and sexual behavior. The study suggests that the absence of these genes impairs the ability to detect certain pheromones, leading to behavioral abnormalities.
Researchers are developing more realistic training simulations that take into account fatigue, stress, personal values, emotion, and cultural influences to improve skill attainment. The goal is to steer trainees away from behaviors contributing to crowd aggression, such as flaunting weapons or authoritarian governance.
A study of 145 stroke patients found that those with lesions in the frontal, lenticulocapsular, and pontine base areas were more likely to experience uncontrolled anger and aggression. Emotional incontinence, sudden outbursts of emotion, was also commonly observed.
Research tracking over 700 children from adolescence to adulthood found that adolescents watching more than one hour of TV daily were more prone to violence. The link remained even after accounting for other factors like childhood neglect and low family income. The study's findings contradict the common assumption that media violence o...
Researchers observed that biting behavior in Polybia occidentalis wasps is a continuum, transitioning from mild to highly aggressive. This behavior affects the life cycle of individual wasps, influencing foraging and social hierarchy.
The PeaceBuilders program increases children's social competence and positive behavior patterns, leading to improved school climate. The program, which focuses on universal prevention beginning in kindergarten, has a lasting impact on students' aggressive behavior.
Research finds that child-centered parenting and prosocial behavior can break the cycle of destructive behavior in aggressive children, reducing school maladjustment and long-term unemployment. Aggressive children who learn prosocial behavior are more accepted by peers, developing social skills and improving job prospects.
A new violence prevention program, LIFT, has been shown to reduce aggressive behavior in elementary school children by 90% after a single year. The program includes parents, teachers, and peers in monitoring and managing environments to create a safer experience for all students.
A four-year study found that consistently low salivary cortisol levels in boys aged 7-12 are associated with early onset and persistence of aggressive behavior. Boys with low cortisol levels exhibited three times the number of aggressive symptoms and were more likely to be singled out by their classmates.
A new survey of 8,865 Texas middle school students found that parents' attitudes towards fighting have a significant impact on their children's aggressive behaviors. The study also identified three other family factors and practices that are indicative of how likely kids will be involved in fighting and aggressive behaviors.
Research suggests that bullying is a continuum of behaviors, with many students engaging in both bullying and victimization. Teachers and parents can play a crucial role in supporting affected students. Effective interventions require changing school climate and tailoring approaches to address physical aggression and bullying.
A study of 510 preschool children found that those sleeping less than 10 hours a day are at risk for increased behavioral problems, such as oppositional behavior and aggression. The relationship between sleep and behavior problems is complex, with possible interaction effects between variables like temperament and parenting.
A study by Johns Hopkins researchers suggests that classroom disorder can influence aggression levels in first-graders, with high-disorder classrooms linked to increased aggression in later years. Meanwhile, girls and boys from poor communities are also at risk of becoming highly aggressive by middle school.
