In an experiment performed in 1969, Herbert Krugman monitored a test subject through a series of trials that investigated a person’s response to watching television. Krugman discovered that in less than one minute from the beginning of viewing the television, the test subjects brainwave patterns switched from beta waves (associated with active, logical thought and critical analysis) to alpha waves. When the subject stopped watching television and began reading a magazine, the brainwaves reverted to beta waves.
