Illustration of the paradigm. The stimulus used in the experiment has been a photograph of a real person, here replaced by a drawing due to privacy reasons. The left and right columns display the sequence of events during a gaze-following/iris-color mapping and an arrow-direction/arrow-color mapping trial, respectively. Each trial started with a blank fixation period followed by the presentation of the cue. In each individual trial, the demonstrator’s face and the arrows look/point toward a randomly selected target, and the color of the iris and the arrows, chosen independently of each other, matched one of the targets. After cue presentation, the participants had to wait with their response until the central fixation dot disappeared.
- Figure 2.
Both panels a and b show the same contrasts/ROIs at two threshold levels. White encircled is the visual motion ROI (Yarkoni, n.d.) and pink encircled is the mGFP (Marquardt et al., 2017). Blue-encircled areas belong to the arrow contrast and red-encircled areas to the gaze contrast at the respective statistical thresholds.
- Figure 3.
In a and b, the HRF estimates for the four different conditions in the left- and right-hemispheric mGFP and visual motion ROI, respectively, are shown. Shaded areas represent the 95% CIs. Especially in the left mGFP, the dominance of activity related to the arrow-direction following condition is obvious.
