A teaching film for the 14 to 18 age range. Animals teach us the five steps of stimulus response. Pigs show how they perceive stimuli in the first moments of life, and demonstrate their remarkable receptors. Hens run obstacle courses and show that they too, have the mental co-ordination to learn from videos. Calves make us aware of their internal as well as external effectors and we discover the surprising ways in which these animals respond to the stimuli in their environment.
All these steps are made memorable by familiar animals revealed as they have never been see before. From this we can see how cruel and barbarous are battery cages for hens and metal cages so that sows cannot move.
