If a conditioned stimulus (cs) is presented without further pairings with the unconditioned stimulus (us), the cs will gradually lose its capacity to elicit the conditioned response. this is the definition of:

This is the definition of respose extinction.

Explanation:

For example, you taught your dog to sit everytime you grab his leash to go for a walk. Over time you started to let him run in the backyard to exercise, and you show him the leash to just call his attention. One day you grab the leash to take him for a walk, and you realize he does not sit anymore at the stimulus. This is a case of response extinction.        

answer; (false);

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
