Abstract

Alpha power correlates with psychometric intelligence. Closing your eyes creates an artifactual spike in alpha. Therefore, if the alpha to intelligence correlation is causal, people should be more intelligent when they close their eyes. We tested this on N=96 participants randomly assigned to a fluid intelligence subtest with their eyes either open or shut. It did not change their intellectual performance.

Keywords: Intelligence, Alpha Power, Visual Impairment
