Concepts

Concepts do not have to begin as explicit words inside a head. In Braitenberg’s framing, they can begin as stable regions of selective response: some stimuli fall together because the mechanism treats them together.

Vehicle demonstrationRecurring responses

Keep the body fixed and move the main source around. The category is not stored as a word; it shows up in the repeatable shape of the response.

DemonstrationConcept-like distinctions can begin as stable differences in response. The body does not name the regions, but it does not treat them as the same either.

The temptation is to think a concept appears only when a system can name it. Braitenberg pushes earlier. If a mechanism groups situations, responds similarly across them, and draws boundaries that matter for action, something concept-like is already in play.

This does not mean the concept is linguistically explicit. It means the system’s organization already carves the world into kinds.

Key idea

A concept can begin as a stable pattern of inclusion and exclusion. If the mechanism repeatedly treats different cases as the same kind of thing, it has already acquired a practical category.

Categories can be built from prototypes

One way to see this is through prototypes. Stimuli get assigned not because they match a verbal definition, but because they lie nearer to one response center than another. Shift the prototypes and the concept boundary shifts with them.

That is enough to make concept formation feel less mysterious. The mechanism does not need to start with a symbolic taxonomy. It can start by responding selectively in a structured space.

Concepts can be treated as regions of selective response before they become explicit symbols. Move the prototypes and the categories move with them.

Figure 7aMove the response centers and the category boundary moves too. Concept-like behavior can emerge from selective response in a shared space.

Concepts stay tied to use

The practical point is that categories are valuable because they guide what comes next. A concept is useful not because it exists in the abstract, but because it makes some actions available and others unavailable.

Concepts can be treated as regions of selective response before they become explicit symbols. Move the prototypes and the categories move with them.
