Learning consists of getting the organism to make a particular response or series of responses when the appropriate stimulus is presented. Some responses are simple, such as typing and some assembly line work, while other response patterns are quite complex, such as solving a calculus equation or supervising a work group.Co change an organism’s behavior or to motivate it to learn a new response, the trainer identifies the desired response and selectively reinforces it. This process is often called behavior modification, and it is based on the simple principle that people tend to do what they are reinforced for doing. Changing a person’s behavior involves reinforcing a different response. The response must be compatible with the physical abilities of the organism. Rats cannot be trained to fly, and managers cannot be trained to be in two places at the same time or to make their days 26 hours long.If the organism already knows how to make the correct response but needs to learn when to do it, training consists of creating the stimulus environment, getting the organism to make the correct response, and then reinforcing it. This sequence is called an S-R bond and the process is diagramed as:
