Eric does not really know how to answer the essay question about cognitive dissonance on his social psychology exam. he decides to write as many facts as he knows about the topic of attitudes in his exam book, hoping that the professor will not read the exams too closely and will be impressed enough by the length of his essay to give him a good score. eric is hoping to take advantage of the central route to persuasion. the peripheral route to persuasion. the sleeper effect. dissonance-related insufficient justification.

the peripheral route to persuasion

Explanation:

the peripheral route to persuasion refers to a method of persuasion that rely on OTHER FACTORS BESIDE the actual content of argument/message given in the persuasion.

This route tend to be used to manipulate the perception or the  emotion that people feel.  This is suitable with the excerpt above because we can see that Eric is trying to influence the professor making his essay look compact rather than actually produce a good quality Essay.
