Players from more aggressive countries were less aggressive towards fellow players, while those from countries with higher unemployment rates traded more cautiously.
A study of over 100 children in China found that playmates with bad tempers led to more aggressive pretend play. However, a child's own temperament did not predict this outcome, suggesting that make-believe aggression may actually help social and emotional development.
A computer-based training program has been developed to reduce negative responses to social conflict by minimizing hostile attribution bias. The training exposes participants to ambiguous word fragments that can form either aggressive or non-aggressive words, helping them to differentiate between the two.
Two 14-year longitudinal studies found that people with disagreeable personality traits, such as being combative and manipulative, are not more likely to achieve power than those who are nice. In contrast, extroverts were the most likely to advance in their organizations based on sociability, energy, and assertiveness.
A new study found that genomic traits of the hive are strongly associated with how fiercely its soldiers attack. The research suggests that the genetic makeup of the society, not individual bee genetics, plays a key role in aggression.
Researchers at York University found that the mixing of African and European genetics led to hyper-aggression in invasive African hybrid honey bees (AHB). The study sequenced genomes of AHB colonies and identified mutations associated with their aggressive behavior.
Paper wasps use social eavesdropping to learn about the fighting ability of potential rivals, allowing them to rapidly assess and avoid opponents. This complex behavior is surprising given their relatively small brains, highlighting the importance of social environment in shaping sophisticated behaviors.
Research reveals that traumatic stress can strengthen amygdala pathways involved in emotion and social behaviors, leading to increased aggression. Deep brain stimulation may be a potential target for treating post-traumatic stress disorder (PTSD) related aggression.
