Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is a “bridge”?
A
An event marker that identifies that training is about to commence
B
An event marker that identifies an undesired response to indicate to the animal that they have not conducted the desired behaviour
C
An event marker that identifies the desired response and “bridges” the time between the response and the delivery of the primary reinforce (e.g. clicker)
Explanation: 

Detailed explanation-1: -A bridge is a stimulus that has been associated with a primary reinforcer through classical conditioning. This process creates a conditioned positive reinforcer, often called a conditioned reinforcer or CR for short.

Detailed explanation-2: -Bridge training is a form of operant conditioning, this is where an animal learns his behaviour has a consequence, for example, the dog sits when we request it and he gets a treat or a pat. He did something and his behaviour made something happen.

Detailed explanation-3: -Bridging Stimulus-(Common use) An informative stimulus, sometimes called a marker signal, that pinpoints the exact moment that the behavioral criterion (for that approximation) is met.

Detailed explanation-4: -The clicker is commonly called a conditioned reinforcer . It is a neutral stimulus paired consistently with a primary reinforcer.
