When shaping new behaviors the most important part that is often forgotten is to use the CR(signal bird within ONE second of good behavior). The titbit can be seconds later. Shaping operant equation is: When under these conditions, and if bird responds right, instant CR, and then reward. WHEN(specific conditions), IF(preforms good behavior),CR(in one second), THEN(reward). If a signal is more than one second from good behavior it could take hundreds of positive trials before correct behavior is learned. Signal under one second and you will see good behavior response in about 21(80% proficiency, Grice) positive trials. Good shaping and chaining
