This study examines how external auditors’ accessibility to “tone at the top” knowledge impacts subsequent audit judgments. To examine this relationship, a decision aid is investigated that differentially facilitates the auditors’ retrieval of “tone at the top” evidence from memory. Results of an experiment indicate that, holding the client’s “tone at the top” constant, the structure of a control environment decision aid influences the auditors’ mental representation of the “tone at the top.” Further, favorable “tone at the top” mental representations transfer to induce relatively favorable control environment and fraud risk assessments, and greater reliance on management’s explanation for variances detected in analytical procedures. Mediation analyses identity the control environment assessment as a mediator between the influenced mental representations transfer to induce relatively favorable control environment and fraud risk assessments, and greater reliance on management’s explanation for variances detected in analytical procedures. Mediation analyses identify the control environment assessment as a mediator between the influenced mental representation and the subsequent fraud.
