Aggression is a multi-dimensional concept, but it can be generally defined as behavior that inflicts pain or harm on another. [ 2 ] The genetic-developmental theory states that individual differences in a continuous phenotype result from the action of a large number of genes , each exerting an effect that works with environmental factors to ...
The weapons effect is a controversial theory described and debated in the scientific field of social psychology.It refers to the mere presence of a weapon or a picture of a weapon leading to more aggressive behavior in humans, particularly if these humans are already aroused. [1]
The frequency of physical aggression in humans peaks at around 2–3 years of age. It then declines gradually on average. [146] [147] These observations suggest that physical aggression is not only a learned behavior but that development provides opportunities for the learning and biological development of self-regulation. However, a small ...
Agonistic behaviour is a result of evolution, [5] and this can be studied in a number of species facing different environmental pressures. Though agonistic behaviours can be directly observed and studied in a laboratory setting, it is also important to understand these behaviours in a natural setting to fully comprehend how they have evolved and therefore differ under different selective ...
Behavioral ecology, also spelled behavioural ecology, is the study of the evolutionary basis for animal behavior due to ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined four questions to address when studying animal behaviors: What are the proximate causes, ontogeny, survival value, and phylogeny of a behavior?

A heavily studied example of a fixed action pattern is the feeding behavior of the Helisoma trivolvis , a type of snail. A study has shown that the intricate connections within the buccal ganglia (see nervous system of gastropods) form a central system whereby sensory information stimulates feeding in the Helisoma.
