The statement regarding nonhuman primate calls that is not true is that they demonstrate linguistic productivity. Linguistic productivity refers to the ability to create an infinite number of new messages through the combination and recombination of symbols or elements within a language. Nonhuman primate communication does not exhibit this feature; their calls are generally fixed and context-specific, rather than open-ended and combinable in the way human language allows. The other statements regarding nonhuman primate calls hold true. Firstly, these calls typically occur in response to specific environmental stimuli, such as the presence of predators or food sources, which can trigger distinct vocalizations. Additionally, calls can vary in intensity and duration, reflecting different emotional states or the importance of the signal being conveyed. However, they lack the complexity and generative properties seen in human language, which is why the assertion about linguistic productivity stands out as inaccurate.
