marginally significantp = .083
Similarly for the best-fitting slope, although the main effect of sensory detail was marginally significant ( F (2,26) = 2.74, MS = 6051, η p 2 = .174, p = .083), there was a significant quadratic trend ( F (1,13) = 5.70, MS = 11940, η p 2 = .305, p < .05) suggesting that the slope was most negative for speech with an intermediate amount of sensory detail.
