Early research into the impact of exposure showed that differences in subjective frequency yielded different results even when the frequency was identical. Hoorens and Nuttin tested whether subjective frequency could be an explanation for the name-letter effect by asking subjects to rank-order the entire alphabet twice, once according to their letter preference and
