DETECTOR 1)2)4)
← Back
Any device usable to discover and measure some characteristic of an environment or a system.
In biological systems, the famous "Frogs Eye" experiment by J.Y LETTVIN et al "… showed how the built-in classes of visual detectors in the frog's retina correspond to perceptual categories" (J.L. SNELL, 1988, p.360).
This also shows that biological detectors have an ingrained evolutive history and are not only detectors but moreover selectors and transducers whose transparency is far from total. (See LOTKA's concept of descriptor). It would be interesting to define and study the nature of social detectors. Values, norms, ideologies, etc… are probably such social selective detectors.
