In the article “Double Dissociation of Spontaneous Alpha-Band Activity and Pupil-Linked Arousal on Additive and Multiplicative Perceptual Gain,” by April Pilipenko and Jason Samaha, which appeared in the May 8, 2024 issue, an error was present in one of the formulas. In the Materials and Methods, GLM criterion, there is a typo in the mathematical formula as well as a mistake in the written description. The corrected formula and description appear below:
GLM criterion. C was computed by taking the negative of the sum of the intercept and alpha power coefficient and subtracting that by half the sum of the stimulus presence coefficient and the interaction coefficient.
