Plagiarism and Paraphrasing Criteria of College and University Professors

Abstract

In Study 1, college professors determined whether each of 6 rewritten versions of a paragraph taken from a journal article were instances of plagiarism. Results indicated moderate disagreement as to which rewritten versions had been plagiarized. When another sample of professors (Study 2) was asked to paraphrase the same paragraph, up to 30% appropriated some text from the original. In Study 3, psychology professors paraphrased the same paragraph or a comparable one that was easier to read. Twenty-six percent of the psychologists appropriated text from the original version, whereas only 3% appropriated text from the one that was easier to read. The results of these studies are discussed in the context of existing definitions of paraphrasing and plagiarism.
