to me it looks like a negative reinforcement
Bob does the dishes to avoid aversive stimuli from his mom

answer is
Negative Reinforcement


I learn better with examples for each so here are some I found:

Positive Punishment If you stroke a cat's fur in a manner that the cat finds unpleasant, the cat may attempt to bite you. Therefore, the presentation of the cat's bite will act as a positive punisher and decrease the likelihood that you will stroke the cat in that same manner in the future.

Negative Punishement
When a child "talks back" to his/her mother, the child may lose the privilege of watching her favorite television program. Therefore, the loss of viewing privileges will act as a negative punisher and decrease the likelihood of the child talking back in the future.



Positive Reinforcement:
A mother gives her son praise (positive stimulus) for doing homework (behavior).
The little boy receives $5.00 (positive stimulus) for every A he earns on his report card (behavior).

Default Behaviors

good example -

another one:

if a child does not take his antibiotics, he is not allowed to eat dessert...this is an example of what type of behavior:

a) positive reinforcement
b) negative reinforcement
c) positive punishment
d) negative punishment















Answer: D, negative punishment

Negative punishment happens when a certain desired stimulus is removed after a particular undesired behavior is exhibited, resulting in the behavior happening less often in the future.

Found that one online....

'Khans Cases' does a good job explaining the differences

Sounds like negative reinforcement. Its like a person does something in order to convey the message towards someone or something therefore the person achieves thr aim, that is not to get scolded ( so as to say)

Default explanation

The way I understand it you are trying to decrease a behavior (not taking antibiotics) therefore it is a punishment. And since you are removing something (dessert) it is negative.
