abstract="Subjects were required to press the button on a Cenco impulse counter as fast as possible for a minute (1) in the morning, and (2) in the evening after Amphetamine had been given just before lunch. All mean values for evening tests were higher on days when Amphetamine was taken. This is shown both in the absolute values for the evening trials and in the differences between morning and evening values. These results are compared with other findings which show that fusion frequency is higher on days when Amphetamine is taken. (PsycINFO Database Record (c) 2012 APA, all rights reserved)<p />",
