Susan and Robert are the parents of three children. One night while the family was sleeping, a fire broke out next door. Susan and Robert heard the fire trucks and rushed out to see what was happening
None of the children woke up, even with the sound of sirens close to the house. Why did the parents wake up, but the children didn't wake up?
What will be an ideal response
The reticular formation activation system, which filters stimuli, awakened the parents, who were responsible for the safety of their children. It allowed the children to ignore the stimuli so that they could get their rest, because the parents were in charge of the situation. It is also possible that the children were in a deeper stage of NREM sleep at the time the sirens sounded, depending upon when they were put to bed.
