Child not eating vegetables. His mother stas giving a chocolate each time he finishes vegetables in the diet. The condition is
**Core Concept**
The underlying principle being tested is the concept of operant conditioning, specifically the use of positive reinforcement in behavior modification. This involves associating a desired behavior (eating vegetables) with a pleasing stimulus (receiving a chocolate).
**Why the Correct Answer is Right**
The mother is using a technique called "token economy" or "operant conditioning" to encourage the child to eat vegetables. By providing a tangible reward (chocolate) each time the child finishes their vegetables, she is creating a positive association between the behavior and the outcome. This can lead to an increase in the desired behavior, as the child learns to link the reward with the action. The mother is leveraging the child's natural desire for sweets and using it as a motivator to promote healthy eating habits.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant to the scenario described, as it does not address the use of positive reinforcement or operant conditioning.
**Option B:** This option may be a potential consequence of the mother's actions, but it does not accurately describe the underlying principle being tested.
**Option C:** This option is incorrect because it describes a different behavioral modification technique (aversive conditioning), which involves associating an unpleasant stimulus with an undesired behavior.
**Clinical Pearl / High-Yield Fact**
It's essential to note that using rewards to modify behavior can be an effective short-term strategy, but it may not lead to long-term changes in behavior. A more sustainable approach might involve educating the child about the importance of healthy eating and involving them in meal planning and preparation.
**Correct Answer: D. Operant Conditioning**
