Document Summary
Tinbergen"s questions: why does an animal exhibit a particular behavior, niko tinbergen divided this over-arching question into four separate questions, each one focusing on a different aspect of the behavior. The influence of genes is especially clear in innate behaviors. Example: tinbergen"s classic goose egg straying from nest: Studying behavior tends to focus on simple behaviors - are more easily studied and understood. Feature detection: nervous system must process stimuli in order for a response to be carried out, stimulus recognition often carried out by feature detectors , e. g. Hormonal influence on behavior: the complexity of hormones on behavior can be demonstrated in the anolis lizards. Studies of the north american vole, in the genus microtus, have also revealed how genes for adh receptors influence behavior. Learning: genes are not the only determinants of behavior. Learned behaviours - depend on individual"s experience: even neurologically simple organisms have capacity to learn.
