    Any task involving words is likely to be affected by word frequency. For example, Howes and Solomon (1951) show that the visual duration threshold necessary for correct report of those words when they are presented via a tachistoscope (an old-fashioned machine that presents visual materials for an exact small amount of time milliseconds^([sic])) depends on the word frequency: People can do it more reliably for higher-frequency words.
