Passage

Passage A One function of language is to influence others’ behavior by changing what they know, believe, or desire. For humans engaged in conversation, the perception of the most common vocalization stimulus.

While animal vocalizations may have evolved because they can potentially alter listeners’ behavior to the signaler’s benefit, such communication is—in contrast to human language—inadvertent, because most animals, with the possible exception of chimpanzees, cannot attribute mental states to others. The male Physalaemus frog calls because calling causes females to approach and other Many animal vocalizations whose production initially seems goal-directed are not as purposeful as they first appear.

Passage B Many scientists distinguish animal communication systems from human language on the grounds that the former are rigid responses to is spontaneous and creative.

In this connection, it is commonly stated that no animal can use its communication system to lie. Obviously, a lie requires intention to deceive: to judge whether a particular instance of animal communication is truly prevarication requires knowledge of the animal’s intentions. Language philosopher H. P. Grice explains that for an individual merely a conditioned reflex: animals may use communicative signs but lack conscious intention regarding their use.

But these arguments are circular: conscious intention is ruled out a priori and then its absence taken as evidence that animal communication is fundamentally different from human language. In fact, the narrowing of the perceived gap between animal communication and human language revealed by recent research with chimpanzees and other animals calls that animals respond mechanically to stimuli, whereas humans speak with conscious understanding and intent.

Answer choices

  1. They Implicitly Agree4% picked this

    the extent to which communication among humans involves the ability to perceive the mental

    Both passages think that humans perceive the mental states of others. Neither gets into specifics about "to what extent" humans have this ability. They're arguing about the mental capacities of nonhuman animals mainly (although the author of passage B takes human communication down a notch in its specialness). But we can only care about human communication if it's being compared to nonhuman communication.

  2. Not Discussed: the importance6% picked this

    the importance of determining to what extent animal communication systems differ

    They would disagree over "to what extent animal communication systems differ from human language", but they never talked about how important it is to make that assessment. They might agree "It's important to make this assessment" and just disagree in their assessments. But all we know is that they disagree in their assessments of how much animal communication differs from human language.

  3. Correct70% picked this

    whether human language and animal communication differ from one another qualitatively or merely in a

    Why this is right

    Passage A thinks that human communication is on a different level (the first sentence of its second paragraph). Such communication (animal communication) is -- in contrast to human language -- inadvertent. (i.e. human language is intentional) Passage B thinks it's merely a matter of degree. In its final sentence it literally says that recent findings have called into question "the assumption that the difference between animal and human communication is qualitative rather than merely quantitative".

  4. No Support Passage B: chimps14% picked this

    whether chimpanzees' vocalizations suggest that they may possess the capacity to attribute mental

    We'd be stretching our guess at what Passage B would say by citing her opinion on chimpanzees, given that she never discussed them. Our guess is that the author of Passage B would say "sure, they may possess conscious intention / the ability to attribute mental states". But the author of Passage A could actually agree here, as he singled out chimpanzees as a possible nonhuman exception that could still perceive mental states.

  5. No Support Passage B: evolved7% picked this

    whether animals' vocalizations evolved to alter the behavior of other animals in a way that

    We have no idea what Passage B's opinions are when it comes to evolution and adaptations relating to communication.
