Final answer:
An anticipatory system works by projecting likely scenarios based on past experiences and social norms to prepare the body for future needs before they arise. The body's response to these anticipated situations promotes behavior that is beneficial to the body and sharpens our awareness of the world.
Step-by-step explanation:
An anticipatory system works by the brain projecting likely scenarios based on past experiences and social norms to prepare the body for future needs before they arise. This process is called allostasis, which involves storing neural pathways triggered by stimuli to provide a close match to the current situation.
The body's response to these anticipated situations can involve increased heart rate, pupil dilation, or motion. These physiological responses help to promote behavior that is beneficial to the body and enhance our awareness of the world.
