I am delighted that we are starting out the New Year with a conversation with Dr Joe Layng. Dr Layng is a behavior analyst who has over 40 years' experience in the experimental and applied analysis of behavior, with a particular focus on the design of teaching/learning environments. In Part 1 of our conversation Joe defined contingency adduction and shared several fascinating experiments that were done with pigeons. Pigeons showed self awareness by passing the mirror test.
