Dogs have become closely associated with humans through domestication and have also become sensitive to human communicative signals. Generally, they have a lot of exposure to human speech, especially during play, and are believed to have a good ability to recognize human speech. Two studies investigated the ability of a single dog that was believed to be exceptional in its understanding of language. Both studies revealed the potential for at least some dogs to develop an understanding of a large number of simple commands on the basis of just the sounds emitted by their owners. However the studies suggested that visual cues from the owner may be important for the understanding of more complex spoken commands.
Clicker training is a nickname given to a positive reinforcement training system based on operant conditioning. Clicker training can also be referred to as marker training. The system uses conditioned reinforcers which are able to be delivered more quickly and more precisely than primary reinforcers such as food. The term 'clicker' comes from a small metal cricket adapted from a child's toy that the trainer uses to precisely mark the desired behavior; however, some trainers use a whistle, a word, or even a light as the conditioned reinforcer. The trainer delivers a primary reinforcer, such as a toy or treat, after the noise or signal. A common critique of clicker training is that it is prone to the overjustification effect.
