Teaching an Australian marsupial to choose life


This article, by Amina Khan, was published in the LA Times on April 17, 2010. It describes a method that scientists used to get the Australian quoll to stop eating poisonous cane toads. They took baby quoll and fed them tiny cane toads laced with a nauseating agent to try and have them associate the nauseating effect with the cane toads. They released them into the wild and their method worked to help prolong the life of the Australian quoll.

This article correlates perfectly with chapter 5 and operant conditioning. These toads were laced with an undesirable agent that caused nauseousness in the quoll. This agent was a negative reinforcer. When the quoll suffered the negative effects of the nauseating agent they declined the toads in order to avoid the negative consequences.
