We examined the effect of encoding quality (how much attention was allocated to the to-be-remembered event) and retention interval (how much time elapses between encoding an event and the interview) on the verbal accounts of truth tellers and liars. Truthful and deceptive participants (n = 149) reported a social interaction (a verbal exchanged between two individuals) immediately or after a three-week delay. To manipulate encoding quality, the content of the exchange was important for, and intentionally attended to by, all liars and half of truth tellers (intentional encoding) but unimportant for half of truth tellers (incidental encoding). In the immediate condition, truth tellers in the intentional condition reported more details than liars and truth tellers in the incidental condition. All truth tellers reported fewer details after a delay versus in the immediately condition, whereas liars reported equivalent detail at both retrieval intervals. No differences by veracity group emerged in detail reported after delay. Thus, oft-reported finding ‘truth tellers provide more detail than liars’ holds true when the event is intentionally encoded by truth tellers who are interviewed without delay
