The organizational hypothesis has been a dominant concept in behavioural endocrinology for many decades. However, in some cases the effects of hormones on behaviour do not neatly fit into organizational or activational categories. Discuss an example where hormones have documented effects on behaviour in a manner that does not completely fit the classic organizational/activational distinction. You should clearly describe how it differs from other examples that do fit into organizational effects and activational effects. What are the implications of your example for the organizational hypothesis? Should we discard this framework? Modify it? Or is the concept of the organizational hypothesis rigorous enough to handle such exceptions?
