Consider the sensation of licking an object nearby. How can you predict its texture? The answer lies in your childhood experiences. Research from 2002 highlighted that infants under the age of two explore their environment by mouthing objects approximately 80 times each hour. This early stage of life allows us to accumulate a vast array of tactile sensations from various materials. Through the phenomenon known as cross-modal perception, our brains can seamlessly access this repository of sensory memories, even years later. According to Hebb's rule, neurons that activate simultaneously strengthen their connections. Thus, when you encounter an object that is porous, rough, or smooth, your brain retrieves those formative experiences and conjures the associated feelings. Remarkably, even if you've never actually tasted a couch pillow, your mind can still simulate what that would feel like.
