Yes, the explanation provided in the text is scientifically true, even though it is written in informal, colloquial Sinhala.
The author is using a "street smart" explanation to describe complex neurological and cognitive phenomena known as Proprioception, Procedural Memory, and Body Schema Integrity.
Here is an explanation of the text and the science behind why it is correct.
1. The Core Argument: Gradual Adaptation
The text argues that if you suddenly attached long hair to someone unused to it, they would struggle (e.g., using the toilet). However, because hair grows slowly over years, the person adapts incrementally.
* Scientific Truth: This is accurate. The brain possesses neuroplasticity. As physical attributes change slowly, the brain updates its "map" of the body to accommodate these changes without the person consciously realizing it.
2. "Muscle Memory" (Procedural Memory)
The author cites "muscle memory" (walking, driving, typing) to explain how women instinctively move their hair out of the way without looking.
* Scientific Truth: In psychology, this is called Procedural Memory. When a task (like sweeping hair over the shoulder before sitting) is repeated thousands of times, the brain moves the processing from the conscious cortex to the basal ganglia and cerebellum. It becomes automatic. You don't "think" about moving the hair; your body just does it, just like a driver shifts gears without looking at the stick.
3. Spatial Awareness & "Body Schema Extension"
The text uses examples like driving a car (knowing the size of the vehicle), wearing high heels, or wearing a saree. It claims the brain "senses" where the hair ends or where the fabric is.
* Scientific Truth: The author explicitly mentions "Body Schema Extension" at the end, which is a legitimate concept in neuroscience.
* Body Schema: This is the brain's internal model of the body's position in space.
* Tool Incorporation: When we use a tool (or wear a long dress, or have long hair) for a long time, the brain treats that object as a part of the body. The brain extends its Peripersonal Space (the space immediately surrounding the body) to include the hair.
* This is why a woman "knows" her hair is about to dip into the water or touch a dirty surface without looking at it—her brain maps the hair as an extension of her head.
4. The Robotics Comparison
The text concludes by mentioning that this is a major problem in Robotics—that things humans do easily (due to muscle memory/awareness) are incredibly hard to program into robots.
* Scientific Truth: This is known as Moravec's Paradox. It is comparatively easy to make computers do hard things (like advanced calculus or chess), but incredibly difficult to make them do "easy" things (like folding laundry, walking without falling, or managing loose wires/hair). The author is 100% correct here; robots lack the innate "body schema" and proprioception that biological entities develop naturally.
Summary
The Sinhala comment is a very accurate, albeit informal, lecture on Cognitive Science.
It correctly identifies that managing long hair isn't a "chore" but a subconscious, automated process derived from:
* Proprioception (Sensing body movement).
* Peripersonal Space extension (Treating the hair as part of the body).
* Procedural Memory (Habitual movement).
Next Step: Would you like to know more about Moravec's Paradox and why simple human physical tasks are so difficult to program into the Rust binaries or automation scripts you work with?
