Which follow from a communication system LACKING duality of patterning?
Hints
- Three are consequences of one signal per message; one confuses duality with a different feature.
- Reference to the absent is displacement, which is independent.
Show the answer
- B. The number of messages is limited by the number of signals
- C. The system cannot build long messages from short parts
- D. Every new message requires a new signal to be learned
Why
The first three are the same limitation stated three ways. Displacement is independent, the bee dance refers to a food source that is elsewhere and in the past, and has no duality whatsoever, which is exactly why the features must be assessed separately.
