Simple (paired t -) tests showed for the comparison of Fabrics 1 and 2 (the least and second least liked) a highly significant difference (t = -6.8, p < 10 -5 ), whereas Fabrics 3 and 4 (the second most and the most liked fabrics) were not significantly different ( t = -1.0, p > 0.1) and ratings for Fabrics 2 and 4 were just significantly different ( t = -2.3, p < 0.05).
While we also measure frontal beta-activity that changes with subjective states of pleasantness, this effect did not reach statistical significance when adjusting for multiple comparisons; hence, although there may be suggestive evidence of observing such structures in our data, our conservative analysis approach and the inverse problem preclude strong inferences concerning the involvement of these brain regions for our results.
