[...] Stephenson (1967) trained adult male and female rhesus monkeys to avoid manipulating an object and then 
placed individual naïve animals in a cage with a trained individual of the same age and sex and the object in 
question. In on case, a trained male actually pulled his naïve partner away from the previously punished 
manipulandum during their period of interaction, whereas the other two trained males exhibited what were 
described as "threat facial expressions while in a fear posture" when a naïve animal approached the manipulandum. 
When placed alone in the cage with the novel object, naïve males that had been paired with trained males showed 
greatly reduced manipulation of the training object in comparison with controls. Unfortunately, training and 
testing were not carried out using a discrimination procedure so the nature of the transmitted information cannot 
be determined, but the data are of considerable interest.
