The conditioned response, in classical conditioning, is the response that is elicited by a conditioned stimulus (a previously neutral stimulus). In the example given in the above question, seeing a bottle on the grocery store shelf is a neutral stimulus which initially did not elicit any nauseous feeling, but is now become a conditioned stimulus that elicits a nauseous feeling, which is a conditioned response.
Explanation: Conditioning is the phenomenon whereby a response or reaction is associated to a particular stimuli.
For example when a dog salivates at the sound of a bell, because it has been conditioned to expect food whenever it hears the sound.
Therefore in the case of Luna above, because she threw up after drinking Gatorade, she has associated the response of throwing up to the taste of Gatorade, and even the sight of the bottles evoke the reaction of nausea. This means that Luna has been conditioned to feel nauseous when she sees Gatorade.
Then the consumption of nutritious breakfast by children would be the predictor variable and academic success would be the criterion variable for the study.
Consumption of nutritious breakfast is the variable being manipulated or used to predict another variable. Academic success is the variable being predicted.
The cardio-respiratory system consists of the cardio vascular system (heart and blood vessels) together with respiratory system (lungs and air ways). These systems work to transport oxygen to the muscles and organs of the body and remove waste products including carbon dioxide.
