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.

What this question is testing

Primary Purpose

Your task

Pin down exactly what the question asks about the passage — a detail, the author's view, the structure, or the main point — before looking at the choices.

Common trap

Answers that restate a true detail from the passage but don't answer the specific question being asked.

Winning move

Anticipate the answer in your own words from the passage, then find the choice that matches that prediction.

Answer choices

  1. No Support Passage A9% picked this

    Are animals capable of deliberately prevaricating in order to achieve

    Passage A never gets into whether animals can lie (prevaricate) in order to achieve certain things.

  2. Correct71% picked this

    Are the communications of animals characterized by

    Why this is right

    Passage A never says the words "conscious intention", so it's a little frustrating to pick this answer. But what does conscious intention mean? LSAT will use a term that's only found in one passage if it means something equivalent to what's talked about in the other passage. When animals communicate, do they have conscious intent? Intent = A goal, trying to do something, a motive When animals communicate, do they have a goal? Are they trying to do something? Are they conscious of what they're trying to do? Passage A says things suggesting that animals are not consciously trying (intending) to make things happen with their communications. - they cannot attribute mental states to others - there's no evidence that frogs think other frogs can think, or believe that communicating with them will make them think thoughts that will alter their behavior. Most importantly, the final sentence, which is kind of serving as the big takeaway: you thought these animal vocalizations were goal-directed (intentional)? maaan, these aren't as purposeful (intentional) as they seem. Passage B starts off right away talking about communication that is an instinctive, automatic response to stimuli vs. human communication that is creative (conscious / goal-oriented). And, of course, the main Author Zone of Passage B is the second paragraph, starting with her "But" pivot. This whole paragraph is about whether we should give animals the benefit of the doubt as to whether they have something resembling the kind of "conscious" mental lives that we think we have.

    Skill tested: Primary Purpose · how this choice captures the passage's function is the move to repeat next time.

  3. Too Strong: most likely1% picked this

    What kinds of stimuli are most likely to elicit

    Neither author was trying to do the countdown of the "Top 5 stimuli that are likely to produce animal vocalizations." We can find some stimuli in Passage A, just used as examples not singled out as special cases. But we would only find the example of the honeybee in Passage B, and it certainly doesn't play a big enough role to call the primary concern.

  4. Wrong Comparison4% picked this

    Are the communication systems of nonhuman primates qualitatively different from those of

    Wow, I thought for sure this would be correct. We would have definitely picked it had it said this: Are the communication systems of humans qualitatively different from those of all other animals?

  5. Out of Scope: scientific consensus14% picked this

    Is there a scientific consensus about the differences between animal communication systems

    Although science experiments, scientists, and scientific topics are definitely discussed in both passages, neither passage is specifically posing the question "is there a scientific consensus?" I don't know how either passage would answer this question, because neither passage got specific about how the scientific community largely feels. The passages are asking "What differences, if any, are there between animal communication systems and human language?" But they're not asking "Have scientists come to a consensus about differences?"
