marginal significanceP = 0.079
The analysis on valence found significant main effect for the sound stimuli ( F (1,16) = 16.812, P = 0.001, partial η 2 = 0.512) and marginal significance for background music ( F (2,32) = 2.744, P = 0.079, partial η 2 = 0.146), although the interaction between them was not significant ( F (2,32) = 0.232, P = 0.794, partial η 2 = 0.014).
