Instinct is a term used to categorize behavior that appears to develop largely independent of experience. Instinctive behaviors are determined by the genetic makeup of the organism. They differ from learned behaviors, which gradually develop as a result of experiences by the organism in its environment. Although behaviors may be categorized as instinctive or learned for ease of discussion, few behaviors, if any, are all one type or the other. Behaviors develop as a result of the interaction of genetic and environmental influences, but some may be affected more by genetic factors, and others more by experience.
