Separating art from the artist: The effect of negative affective knowledge on ERPs and aesthetic experience.

Turning to the secondary hypotheses (see Fig 3B ), nesting the factor knowledge within the relatedness condition revealed that the effect of negative (compared to neutral) knowledge on EPN amplitude was similar in size and direction in the related ( b = -0.28, t = -1.76, SE = 0.16, p = .081) and the unrelated condition ( b = -0.25, t = -1.62, SE = 0.16, p = .107), although in both cases the effect did not reach statistical significance, due to a reduction in power when analysing the effect of knowledge separately within each condition, i.e. for only half of the trials.
