Linguistic properties of writing prompts have been shown to influence the writing patterns contained in student essays. The majority of previous research on these prompt-based effects has focused on the lexical and syntactic properties of writing prompts and essays. The current study expands this research by investigating the effects of prompt cohesion on the cohesive features of student essays. Results indicate that prompt-based cohesion effects were observed for all the measured cohesion variables. Further, these cohesion prompt-effects were stronger than the effects observed for many lexical features and all syntactic features. Implications of these results in light of writing research are discussed.
