When subjects judge whether a test symbol is contained in a short memorized sequence of symbols, their mean reaction-time increases linearly with the length of the sequence. The linearity and slope of the function imply the existence of an internal serial-comparison process whose average rate is between 25 and 30 symbols per second.

A result of this procedure is that other factors in choice-reaction time were also controlled: stimult~s discriminability (10); information transmitted (8) ; and information reduced
