Answer:
The correct answers would be Continuous and Partial.
Explanation:
A trainer wants a pigeon to quickly learn to peck a button to obtain food. She also wants to be sure the behavior is resistant to extinction. So she should use Continuous Reinforcement until the response is mastered followed by Partial Reinforcement.
Continuous reinforcement is the reinforcement of behavior each time it occurs, whereas partial reinforcement is when the behavior is reinforced only some times.
Because the trainer wants to be sure that the behavior is resistant to extinction, so to make it interesting, she should use continuous reinforcement until the pigeon is trained, and then partial reinforcement should be used to keep the interest.
<span>When a woman talks about her problems with a friend, she usually wants sympathy or understanding.
Women usually don't want a solution to their problems, but rather someone to listen to them and understand that they are stressed or sad, and be there for them. They don't want practical advice either, because they will come up with a solution eventually. I don't know who would want the last option - it is clearly incorrect.
