32 Chapter 2 Figure 2.1 Displays and timings of video stimuli of one’s adolescent child engaging in direct gaze and averted gaze in the eye contact task. Videos of parents’ own child were contrasted against videos of an unfamiliar child matching the gender of the parents’ own child, a video of an unfamiliar adult of the same gender as the parent and a video of the self. When parents were presented with a video of the own child and an unfamiliar child or adult, they were asked to answer all three questions, and when they were presented with a video of themselves they were only asked to answer the last question (i.e., “How do you feel at this moment?”). Data acquisition MR images were acquired at the LUMC using a Philips 3.0T Achieva MRI scanner equipped with a SENSE-32 channel head coil. For the eye contact task, T2*-weighted echo planar imaging (EPI) was used with the following parameters: TR = 2200 ms, TE = 30 ms, flip angle = 80°, FOV 220 × 220 × 114.7 mm, matrix size = 80 × 80, voxel size = 2.75 mm3, slice gap = 0.275 mm, 38 transverse slices in descending order. As subjective response ratings were self-paced, number of volumes varied between participants (run 1: M = 152.6, SD = 12.2, range = 128 – 189; run 2: M = 149.1, SD = 12.3, range = 123 – 184). A structural 3D T1 scan was acquired with the following parameters: TR = 7.9 ms, TE = 3.5 ms, TI = 820 ms, flip angle: 8°, voxel size = 1 mm3, 155 transverse slices FOV 195.8 × 250 × 170.5 mm, matrix size = 228 × 177, duration: 4:11 min. The first five volumes were discarded to allow for equilibration of T1 saturation effects. A b0 field map was acquired with the following parameters: TR = 200 ms, TE = 3.2,
