Frequency-specific Flicker Modulates the Cognitive Response to Arithmetic Tasks

In this work, we investigated whether entrained oscillations could affect performance and information processing in a short-term working memory task and arithmetic task. In previous studies, flicker frequencies close to 10.2 Hz increased senior people’s memorization of words that they had learned. We studied the effects of entrained oscillation of alpha peak waves over a broad range of flicker frequencies (0, 6, 11.5, or 18 Hz). The reaction time of the experimental group was faster than that of the control group. Thus, entrained oscillations may help people become more sensitive and cognitive.
