Final answer:
Sensory feedback is essential because it provides information to maintain homeostasis and supports allostasis, ensuring our perceived model of the world matches reality for effective interaction and survival.
Step-by-step explanation:
We need sensory feedback because internal models are not perfect and therefore cannot always accurately predict the outcome of our actions. Sensory feedback helps us learn about the environment and the state of our internal environment. This feedback is crucial for maintaining homeostasis and facilitating allostasis, which is the preparation for future events based on past experiences and concepts. Our brain receives stimuli, integrates information, and projects a picture of the world which helps us navigate and interact dynamically with our surroundings. Emotion and memory, along with sensory feedback, influence our thoughts, perceptions, and behaviors, shaping our reality and promoting survival-based actions.
