Some researchers claim that people tend to gesture less when they articulate what would typically be regarded as abstract rather than physical concepts. To point out that such a correlation is far from universal is insufficient reason to reject the researchers' claim, because some people perceive words like "comprehension" as expressing a physical action, like grasping something, rather than a state of understanding, which is abstract.
Which one of the following most accurately describes the method of reasoning used in the argument?The argument defends the researchers’ general claim against an objection. It says that some apparent counterexamples may not really be counterexamples, because some “abstract” words may be mentally treated as physical concepts.
The method is to use a psychological fact to explain away
apparently disconfirming evidence.
(A) appealing to the ambiguity of a word in an attempt to show that a correlation is universal
This is incorrect. The argument does not try to prove the correlation is universal. It only says lack of universality is not enough to reject the claim.
(B) appealing to a universal psychological generalization in an attempt to support a claim about the use of gestures
This is incorrect. The argument does not give a universal psychological rule. It says some people perceive certain words physically.
(C) citing a psychological fact to try to reconcile a generalization with apparently disconfirming evidence
This is correct. The generalization is that people gesture less with abstract concepts. The apparently disconfirming evidence is that the correlation is not universal. The psychological fact is that some people treat words such as “comprehension” as physical, not abstract.
(D) advocating an explanation for a phenomenon by attempting to demonstrate that other possible explanations are implausible
This is incorrect. The argument does not eliminate other explanations.
(E) offering a reason for believing that a widely accepted generalization requires still more supporting evidence
This is incorrect. The argument defends the researchers’ claim; it does not argue that more evidence is needed.
