In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep volunteers awake for variable amounts of time. One group of participants was kept awake for 24 hours, and the other was kept awake for 48 hours. During periods of forced wakefulness, participants were required to engage verbal learning tasks such as memorizing the definitions of obscure English words. At the conclusion of the period of forced wakefulness, participants were allowed to sleep for as long as they wanted to. When participants awakened, researchers tested them on the learning tasks they completed during the periods of forced wakefulness. The researchers discovered that participants who were deprived of sleep for 48 hours recalled less than those who had been forced to remain awake for 24 hours.

Answer:

If I were designing a study in which I wanted to assess memory, I might ask people to remember three words, then have them recite a phone number to prevent rehearsal of the three new words.

Explanation:

When asked to memorize information, be it words or numbers, for instance, people tend to rehearse it mentally to remember it for a longer period of time. However, it is possible to prevent rehearsal from happening when conducting studies to assess memory. One of the ways is precisely the one described in the question. People were asked to memorize three words, but were prevented from rehearsing them by having to recite a phone number. In that case, as studies have shown, there is memory decay.

When removal of a stimulus in response to a behavior increases the frequency of that behavior, _____ is said to have occurred.

Answers

Answer: punishment, negative reinforcement

Explanation:

When the removal of a stimulus in response to a behavior increases the frequency of that behavior, negative reinforcement is said to have occurred.

What is negative reinforcement?

This is known as negative reinforcement when something unpleasant or difficult is taken away to make the desired action more likely. Kids complete the necessary tasks in order to avoid being nagged. Thus, the desired behavior is produced by eliminating something unpleasant, such as nagging.

Negative reinforcement, which tries to eliminate unpleasant acts or reactions and increase the chance of desired behavior, is an equally successful behavioral management method as a positive reward. The main distinction between negative reinforcement and punishment is that punishment, whether it be positive or negative, tries to reduce or weaken a behavior. Instead, whether it is good or negative, reinforcement works to improve the habit.
