the answer is: A cognitive psychologist enrolls undergraduate students for a computer-based study about the effect of mood on problem-solving behaviors.
Here the requirement for research with human subjects according to the Fed :
"Obtains information or biospecimens through intervention or interaction with the individual, and uses, studies, or analyzes the information or biospecimens; or Obtains, uses, studies, analyzes, or generates identifiable private information or identifiable biospecimens."
The experiment on this ption fulfill the criteria because:
- The experiment should use studies or analytics to obtain some sort of private information from the subjects. (such as their mood)
- The experiment should make some sort of intervention that can be used to measure its hypothesis. (in the case above, the researchers could put the subject under a certain level of stress before telling them to solve a set of problems)
- The researchers need to interact with the subject in a certain way. (since the researchers meet the undergraduate directly, it's considered as an interraction)
Answer: Therapists practice behavior modification by using positive reinforcers to reward closer and closer approximations of a desired behavior.
Explanation:
The behavior modification methods are based on behavioral methodology, this methodology determines that the situations faced by an individual determine their behavior and this can be modified through rewards or punishments in order to eliminate, modify or reinforce it.
Positive reinforcements are additions that are given to the person each time they perform the behavior they want to strengthen. For example, when a child is taught to go to the bathroom, a compliment can be given each time the child asks to be taken to the bathroom. In the beginning, you can "reward" the approximations to the desired behavior until it is fully realized.
I hope this information can help you.
