highly significantp < 0.001
In line with our research hypotheses H1a and H1b, the analyses identified a significant increase for SER heuristic-participants supportive attitude toward CCU [ F (1, 99) = 5.492, p < 0.01; η p 2 = 0.05; M SER-pre = 3.79, SD SER-pre = 0.98; M SER-post = 3.90, SD SER-post = 0.95], as well as a highly significant increase of their acceptance of CCU [ F (1, 87) = 14.505, p < 0.001; η p 2 = 0.14; M SER-pre = 2.60, SD SER-pre = 1.30; M SER-post = 3.00, SD SER-post = 1.34] from pre- to post-measurement (see Table 3 for an overview). 3.3.
