ICC Maps - Self-Evaluation fMRI Task

Description: The collection contains the ICC maps for the task conditions of a self-evaluation video fMRI paradigm with the conditions: "self", "familiar person", "unkown person" and s distractor task. The video paradigm combines self-referential and self-recognition. During scanning, video clips of the participant, a close friend and a foreign person were presented. The protagonists in the videos introduced themselves and talked about self-concept aspects, such as their positive personality traits (emotional and social aspects of self-concept), their expectations about others (social self-concept) as well as their future goals (academic self-concept). Together with the full body recordings (physical self), we assume that the comparison of neural activations between the self- and other condition mirrors neural correlates of the self-concept. To our knowledge this is the first paradigm measuring self-concept related aspects by combining the conditions of self-referential and self-recognition. We tested this paradigm in the framework of a longitudinal study over one year in a sample of healthy participants and individuals with pathological internet game use (group involved problematic and addicted gamers). MRI data acquisition was performed on a 3.0 Tesla MR scanner (SIEMENS MAGNETOM Trio), with a standard multi-channel receiver head coil (12-channel). During the functional self-concept MRI task, 205 volumes were acquired by applying a T2*-weighted echo-planar imaging (EPI) sequence [repetition time (TR) = 2410 ms, echo time (TE) = 25 ms, flip angle (FA) = 80°, field of view (FOV) = 192 mm × 192 mm, matrix size 64 × 64, 42 slices, slice thickness = 2.00 mm, distance factor = 50%, and voxel size = 3 × 3 × 2 mm]. ICC maps were derived for two study groups (n=11 participants with problematic internet use and n=29 helathy participants) from conducting ICC(1,3) type analyses on the different task conidtions and task contrasts of the self-evaluation task (see above) using the fmreli toolbox by Fröhner and colleagues. ICC maps for the following conditions and contrasts werde computed for both study groups: i) self vs. implicit baseline, ii) familiar person vs. implicit baseline, iii) unknown person vs. implicit baseline iv) self > familiar person + unknown person
