Model Statements are designed to modify an interviewee’s expectation of the amount of details required during an interview. This study examined tailored Model Statements, emphasising either spatial (Spatial-MS), or temporal (Temporal-MS) details, compared to a control condition (no-MS). Participants (63 liars, 63 truth-tellers) were randomly allocated to one of three interviewing conditions. Truth-tellers honestly reported a spy mission, whereas liars performed a covert mission and lied about their activities. The Spatial-MS elicited more spatial details than the control, particularly for truth-tellers. The Temporal-MS elicited more temporal details than the control, for truth-tellers and liars combined. Results indicate that the composition of different Model Statements increases the amount of details provided and, regarding spatial details, affects truth-teller’s and liar’s statements differently. Thus, Model Statements can be constructed to elicit information and magnify cues to deceit.
