The corpus callosum is known to be the connector between brain hemispheres, which means that it connects the left side of the brain to the right side. It is this connection that permits for the transfer of information between the two sides of the body. Hence the ability for Elise to write with one hand and steady the paper with the other is as a result of a connection between her left and right brain, which shows growth in her corpus callosum.
The operant condition is also called the shaping of the behavior that occurs based on the teaching of the newly learned behavior and is prompting to the leaning of the behavior through the reinforcement and thus the conditioners are able to motivate to obtain that sort of behavior. Thereby conditioning is done to the external stimulus and the observations are made in a closed setting.
