西蒙栋-知觉单位与表意的个体化（二） (5-5)

Indeed, the number of decisions falls when contrast is shown: if there are only white and black colors in an image, then there are only two possible states for each physical surface unit; if there are various nuances of gray, there is a greater number of possible states, and thus of decisions.

3. The reading of a magnetic tape at high speed is the equivalent of a perception of a photograph at a distance.

4. We could only take account of the degree of the probability of this form’s appearance; there are only a finite number of good forms, whereas unspecified assemblies can be indefinitely varied. But it is only because of this, through the intermediary of a possible coding implying a lower number of decisions, that the good form is easier to transmit. A very simple coding, in the case of straight lines, consists in reducing the number of possible states to two: white and black. It is in this sense that drawing a line is more easily transmitted than an image in different tones of gray.

5. This word is taken here in the sense that Physics gives it, particularly in the theory of the exchange of energy between oscillator and resonator.
