Set of 28 videos: reaction of titi monkeys to the playback of alarm calls of conspecifics.
Experimental paradigm: playback of 10 alarm calls from a member of the group or from a neighbour. For a stimulus of X seconds, we recorded x seconds before the beginning of the stimulus, and X seconds after the end of the stimulus. The stimulus begins after the recorder says "Vas-y!" (Yes, we are french...). Note that for some trials, we playbacked more than 10 calls (these were pilot studies). For these, we stopped coding videos after the emission of the 10 first calls.
Name of videos: YYYYMMDD-HHhMM-subject-stimulus
If the first letter of the monkey name in the stimulus'origin matches the first letter of the name of the subject, then the stimulus is from a member of the subject's family. Otherwise, it is from a neighbouring group.
ex: 20160809-14h51-DN-playback_caracara_ground_DG: The stimulus recorded from DG when he encountered a caracara on the ground is played to DN, they are from the same group. ex: 20160818-09h13-PP-playback_Caracara_down_ML: The stimulus recorded from ML when she encountered a caracara on the ground is played to PP, they are not from the same group.
