We examine the association between several behavioral and electrophysiological indices of impulsivity-related constructs multiple entrepreneurial constructs. Specifically, we investigate if these measures are more useful as predictors entrepreneurship than self-reported impulsivity. Our findings based on two datasets (n = 133 n 142) indicate that impulsivity not robustly associated with constru...
