When attempting to modify a child's behavior using negative reinforcement,

the desired result is that the child
will:

A. Withdraw from certain social
activities

B. repeat behavior for which they
get the desired result

I am thinking (C) is the correct answer,

I think you are right, but read to be sure.

The "desired" result can only be C. If you desired the other two chioces, A would make you a psychological torturer and, B is an answer to positive reinforcement outcome and, is inaplicable.

I understand you're asking about the desired result when attempting to modify a child's behavior using negative reinforcement. Negative reinforcement involves removing or reducing an aversive stimulus to increase the likelihood of a desired behavior occurring again in the future.

Looking at the given options:

A. Withdraw from certain social activities: This option suggests that the child would avoid social activities as a result of the negative reinforcement. This outcome is not associated with negative reinforcement but might be more aligned with punishment or avoidance conditioning.

B. Repeat behavior for which they get the desired result: This option is not related to negative reinforcement. It actually describes a result that is associated with positive reinforcement, where a behavior is encouraged by providing desired consequences or rewards.

C. Avoid behaviors that carry undesirable consequences: This option is the correct answer. When using negative reinforcement, the desired result is for the child to learn to avoid behaviors that have unpleasant consequences. By removing or reducing these negative consequences through negative reinforcement, the child is more likely to avoid engaging in behaviors that lead to undesirable outcomes.

To further support your understanding, it's a good idea to read the resource you provided (http://www.vtaide.com/png/rewards.htm). It will provide additional information and examples related to the topic of rewards and behavior modification.
