‘Drawing to conclusion’: The effect of sketching recall methods to enhance information‐gathering and cues to deceit

Previous research indicated that drawing is a strategic tool in investigations. However, little has been conducted to determine how introduce sketch instruction into an investigative interview. The current experiment compared sketching and speaking separately (sketch-speak speak-sketch conditions) with synchronously which recall method gathered the most information elicited cues deceit. Participants (N = 180) watched video, half were asked tell truth (to friendly agent), whereas other lie corrupt agent) about video either (i) then speak, (ii) speak sketch, or (iii) synchronously. Verbal statements sketches coded for total details, number of people, self-handicapping strategies plausibility. camera perspective was also examined. Truth tellers' verbal rated as more plausible than those tellers. This difference found all three methods largest effect emerging condition. tellers included details their but not sketches. Conversely, people responses. No veracity differences emerged nor strategies. participants conditions. Additionally, reported who spoke sketched. Effects large enough between isolation best detect beneficial information-gathering.
