Instincts And Mechanism Of Behaviour

Instincts and Mechanism of Behaviour

An instinct is the mechanism by which animals and humans can perform complex behaviour patterns without learning or conscious effort. Instinctive behaviours are inherited and have evolved to be adaptive, fitting the organism to its particular role. Instinct is of particular importance in animal behaviours such as courtship, mating, and other reproductive activities. More general behaviours such as feeding and defence may have an instinctive base. Many birds, some grasshoppers, frogs, and a number of other animals have song or call patterns that attract mates and are based upon instinct. Instinctive behaviours often require a stimulus or releaser to initiate them. The herring-gull chick pecks the red spot on the adult's bill, releasing its instinctive feeding behaviour. A releaser will operate only if conditions, both internal and external to the organism, are suitable.

Instinct, Environment and Behaviour (Psychology Revivals)

What can the evolution of animal behaviour tell us about human behaviour? More specifically, how good an account of animal behaviour can we give in terms of evolution, and how do humans fit in with or deviate from the pattern established for other animals? The biological approach to the study of animal behaviour has important implications for psychology, but it is distinctly different. Originally published in 1984, this book provides a basic introduction to biological theories about behaviour, from the classic ethological tradition of Lorenz and Tinbergen to the later sociobiological approach. The principles of experimentation and research involved are assessed critically, especially with regard to their implications for the study of human behaviour. Written specifically for those with little biological knowledge, this book will still be of interest to students of biology and introductory psychology alike.
