of saying claims, stutters, etc...), were not between the ages of 18 and 24, did not finish each claim without stuttering or mumbling, or did not speak loudly and clearly. We also did not use recordings made by claimants who identified as not being heterosexual, because our hypotheses were specific to people who are heterosexual, and in the instructions we specified that they should act as though they are speaking to a member of the opposite sex. We also excluded claimants who spoke with a strong non-American accent, as it has been shown that people who have strong foreign accents are rated to be less believable, and we did not want to create a confound (Lev-Ari & Keysar, in press). When we were finished eliminating the tapes based on the listed criteria, we eliminated any extras using a random number generator and the codes that they were assigned in order to end up with only 10 recordings of claimants of each sex. Of the videos that we did use, we ended up with a mean age of 21.3 for the female claimants and 21.0 for the male claimants. A total of 5 males were in both a romantic relationship and a sexual relationship, 1 male was in a romantic relationship and not in a sexual relations, and 4 males were neither in a romantic relationship nor in a sexual relationship. A total of 4 females were in both a romantic relationship and a sexual relationship, 2 females were not in a romantic relationship and were in a sexual relationship, and 4 females were neither in a romantic relationship nor in a sexual relationship. We used Windows Movie Maker Version 2012 to cut the videos so as to isolate the claims from other another. Claim snippets were 5 second long, all of which start roughly 1 second before the claimant starts speaking, and end roughly 1 second after they finish. For claimants who did multiple takes, we chose the first version of each claim in which the claimant did not stutter, mumble, or look away from the camera while speaking. A total of 80 claim snippets were created; 1 for each of the 4 claims that the 20 claimants made.
