    Foxe of the Nathan S. Kline Institute for Psychiatric Research in Orangeburg, N.Y., and his colleagues recruited
    16 people for tests of attentiveness on four days. Before testing, each individual drank a glass of water. On 3
    days, the drink was spiked with 100 milligrams of theanine, 60 mg of caffeine, or both. The theanine dose was
    equivalent to that in 4 to 5 cups of tea, and the caffeine translated to about 2.5 cups of tea. In the difficult tests,
    participants watched a computer screen and pressed a button when a designated shape appeared
    on the side of a busy visual field to which an arrow had previously pointed. Participants' accuracy differed little
    between days when they got water alone or with only one additive. Accuracy improved dramatically, however,
    on the day that they got the theanine-caffeine combination. The attention benefit lasted throughout the 3 hours
    of testing."
