Children who consumed four or more servings per day were nearly twice as likely to exhibit these behaviors.
Research suggests that children who overestimate their social connections are less aggressive, as they perceive a lower risk of being judged by peers. In contrast, students who underestimate or accurately assess their social standing tend to display more aggression.
New research finds that playing violent video games boosts visual skills but impairs proactive executive control, leading to increased aggression. This reduction in impulse control is linked to increased attention problems and aggression.

A study found that encouraging young people to see happiness rather than anger in facial expressions leads to a decrease in their levels of anger and aggression. The researchers also discovered that this effect can be induced in healthy adults, suggesting that emotion processing plays a causal role in anger and aggressive behavior.
A study found that sexually naïve male mice respond to pup pheromones with aggression, whereas fatherly males do not. Removing the vomeronasal organ in males suppressed aggressive behavior and induced parental instincts.

SWPBIS aimed to alter student behavior through universal expectations implemented across the school.
A study by Penn State researchers found that kindergartners' aggressive behavior can be attributed to varying levels of verbal ability and physiological arousal. The team identified two groups: one characterized by low verbal ability and the other by high emotional reactivity.
A large-scale study found that children with migraine headaches are more likely to experience social and attention issues, as well as anxiety and depression. The study, published in the journal Cephalalgia, suggests that headache frequency is a key factor in these behavioral difficulties.
Researchers identified brain regions involved in affective aggression in mice, which may be similar to those affected in humans. The study's findings could lead to the development of novel approaches to treat chronic affective aggression.

Studies show that exposure to AAS at critical periods during adolescence can impose permanent changes in brain organization and function, leading to physiological and psychiatric effects that may persist into middle age.
A study using molecular imaging found a link between low dopamine levels and aggressive behavior in competitive situations. Participants with lower dopamine synthesis capacity were more likely to act out with aggression when provoked.
Researchers found strong relationships between aggressive behavior and individual variation in genes related to testosterone processing in the brain. The study suggests that selection can shape aggression through changes in gene expression, independent of circulating testosterone levels.
A new study found that men with wider faces, traditionally associated with aggression, are actually more self-sacrifying when their group is competing. The researchers tested this hypothesis by giving students money to play a cooperative game and found that the wider faced men were more generous to their in-group.
A new study shows that chimpanzee Santino's planning and deception abilities are greater than previously thought. He uses innovative strategies like hiding projectiles and inhibiting dominance displays to fool visitors, suggesting a flexible planning ability similar to humans.
A new study found that black women leaders are expected to be assertive, unlike white men and women who are penalized for similar behavior. Black women occupy a unique space in leadership, separate from other groups, with their agency valued over traditional communal roles.
A study published in PLOS ONE found that dietary trans fatty acids are associated with irritability and aggression in both men and women of all ages. The research, which analyzed data from nearly 1,000 adults, suggests a strong link between trans fat consumption and aggressive behaviors.
A new study by Iowa State University researchers found that watching mean screens can activate aggressive scripts in the brain, leading to increased aggression. The study showed that both physical and relational aggression on screen can prime the brain for aggressive behavior, which has significant implications for today's societal norms.
Research suggests the SRY gene, which directs male development, promotes aggression and a fight-or-flight response to stress in men. In contrast, women primarily adopt a less aggressive tend-and-befriend response to stress, influenced by oestrogen and internal opiates.
A new study by Gustavo Carlo found that Mexican-American college students' family and peer attachments are associated with prosocial and physically aggressive behaviors. College students with strong relationships reported less physical aggression and higher empathy levels.
Researchers at Max Planck Institute found that high-ranking male bonobos were more aggressive and had higher mating success, but also invested in friendly relationships with females. These relationships correlated with lower male testosterone levels, challenging the common notion of masculine behavior.
Researchers develop a general model of disinhibition, which occurs when inhibitory forces are temporarily removed, allowing initial impulses to be expressed. This can result in pro-social or anti-social behavior depending on the context.
A new study from Case Western Reserve University found that aquarium fishes are more aggressive in reduced environments, with 182.9 million ornamental fishes at risk. Increasing tank size and complexity can reduce harmful aggressive behaviors, leading to healthier fish.
Researchers found that low serotonin levels weaken communication between brain regions, making it harder to control angry feelings. Healthy volunteers' brains were scanned while viewing angry faces to understand the impact of serotonin on aggression.
Research suggests that competitiveness in video games is a key factor in aggressive behavior, with highly competitive games leading to greater elevations in aggression. In contrast, less competitive games do not elevate aggressive behavior, regardless of violence content.
Research at Queen's University Biological Station reveals that singing shared songs is an attention-seeking behavior often displayed by older males. Song sharing is linked to individual differences like age and neighborhood characteristics.
