Answer: More resistant to extinction than a response that receives continuous reinforcement
Explanation: The effect of partial reinforcement is the occurrence when reinforcement is provided after some correct answers but not after all correct answers. It is clear, then, that reinforcement is given after certain correct responses as a way of conditioning and acquiring certain habits, i.e behaviour, but not always reinforcement is given after literally every correct response, for example, a dog is not rewarded after every successful task. And vice versa adequate punishment is not acted upon each problematic behaviour when one wants to eradicate a particular trait or behaviour. Therefore, it takes longer for partial reinforcement to go through extinction or such reinforcement is more resistant to extinction.
Conditioned stimulus refers to a stimulus that already become a trigger to a certain response due to the process of classical conditioning. From the example above, alexis start to cry after she saw a hospital. Because of this, we can say that the sight of hospital act as the trigger the elicit the response.
