A weakness of the behaviourist approach?

-Research conducted on animals can be questioned in terms of ethics -Although procedues lik the Skinner box allowed behaviourist to maintain a high degree over their experimental subjects may be questionined the ethics of conducting such investigations -Animals were housed in harsh, cramped conditions and deliberatley kept below their natural weight so they were always hungery -Though at the time there were no ethical guidelines for this and the information recieved allowed for real world therapies to be developed, however, this doesn't justify wha tthe animals went through as they were kept in uncomfortable environments for a long periods of time.
