Decades of research have demonstrated that both genetic and environmental factors play a role in a variety of behaviors in humans and animals (e.g. Grigorenko & Sternberg, 2003). The genetic basis of aggression, however, remains poorly understood. Aggression is a multi-dimensional concept, but it can be generally defined as behavior that ...
Aggression is a behavior aimed at opposing or attacking something or someone. Though often done with the intent to cause harm, it can be channeled into creative and practical outlets for some. [1] It may occur either reactively or without provocation. In humans, aggression can be caused by various triggers.
Zur Naturgeschichte der Aggression, "So-called Evil: on the natural history of aggression") is a 1963 book by the ethologist Konrad Lorenz; it was translated into English in 1966. [1] As he writes in the prologue, "the subject of this book is aggression , that is to say the fighting instinct in beast and man which is directed against members of ...
Findings from behavioural genetic research have broadly impacted modern understanding of the role of genetic and environmental influences on behaviour. These include evidence that nearly all researched behaviours are under a significant degree of genetic influence, and that influence tends to increase as individuals develop into adulthood.
The frustration–aggression hypothesis implies that aggression is followed or triggered by a feeling of frustration as proposed by the Yale group. Yet, other studies support contradictory claims. Certain subjects in some studies have shown to not respond aggressively to frustration given their personal, moral and educational backgrounds.
The evolutionary neuroandrogenic (ENA) theory is a conceptual framework which seeks to explain trends in violent and criminal behavior from an evolutionary and biological perspective. It was first proposed by the sociologist Lee Ellis in 2005 in his paper "A Theory Explaining Biological Correlates of Criminality" published in the European ...
Studies have shown that children who are aggressive and have conduct problems are more likely to have anti-social behaviour in adolescence. [40] Early intervention of anti-social behaviour is relatively more effective since the anti-social pattern lasts for a shorter period of time. [ 41 ]
Furthermore, in all animals, the nervous system is the organ of behavior. Therefore, every biological and behavioral variable that influences behavior must go through the nervous system to do so. Present-day research in behavioral neuroscience studies all biological variables which act through the nervous system and relate to behavior. [10]
