Speaker Gaze and Trust

The data and supplementary materials presented here form the basis of our paper "Direct Speaker Gaze Promotes Trust in Truth-Ambiguous Statements" (H. Kreysa, L. Kessler, & S.R. Schweinberger, 2016, PLoS ONE, 11(9), e0162291. doi:10.1371/journal.pone.0162291.).As described in the paper (downloadable here), 35 student participants indicated by button press whether or not they believed a truth-ambiguous statement, uttered by a speaker in one of 36 short video clips. Importantly, the speaker sometimes looked directly into the camera, at other times she averted her gaze.1. DataWe present four datasets as tab-delimited text:1.1. Gaze_RESPrts.txt (responses and RTs for main experiment), with the following variables:- SubjectCode (N = 35)- Video (.avi)- Item (N = 36)- RT from response screen in ms- Response (yes/no)- Orientation (direct gaze / averted right / averted left)- debrief (mention of gaze direction in debrief questionnnaire)1.2 Audioonly_RESPrts.txt (responses and RTs for control experiment), with the following variables:- SubjectCode (N = 37)- Audio (.wav)- Item (N = 36)- RT from response screen in ms- Response (yes/no)- Orientation_original (direct gaze / averted)1.3 Gaze_ratings.txt (post-experimental ratings of the speaker's attributes, main experiment), with the following variables:- SubjectCode (N = 35)- Attribute (6 levels)- Rating-recoded (1: lowest - 6: highest)- Response_time- Rating_trial (6 per participant)- Num.yes (number of yes-responses in main experiment per participant, out of 36)1.4 Gaze_fixations.txt (total fixation time to each AoI during video presentation), with the following variables:- SubjectCode (N = 35)- Video (.avi)- AoI (Area of Interest assigned in SMI BeGaze, see attached example image "AOIs.bmp": eyes, bottomright, bottomleft, topright, topleft, whitespace)- Fixtime (total fixation time per region)Eye movements were recorded using an SMI iViewX Hi-Speed 500 tracker, and fixation events were extracted for each participant using SMI BeGaze (v. 3.4.52).2. Stimulus examplesTwo videos, one with direct gaze (1_Hund_direct.avi) and one with with averted gaze (mirrored to create right-averted gaze: 1_Hund_right.avi)3.
