Joseph Lister efficacy of carbolic acid when applied directly to wounds. Therefore, Lister tested the results of spraying instruments, the surgical incisions, and dressings with a solution of carbolic acid. Lister found that the solution swabbed on wounds remarkably reduced the incidence of gangrene. In August 1865, Lister applied a piece of lint dipped in carbolic acid solution onto the wound of a seven-year-old boy at Glasgow Infirmary, who had sustained a compound fracture after a cart wheel had passed over his leg. After four days, he renewed the pad and discovered that no infection had developed, and after a total of
Name-letter effect counts of any letter, which also caused Nuttin to cast doubt on whether Zajonc's theory could hold true in the real world. Subjective frequency is how frequently subjects a stimulus appears. Name letters may be noticed more and, consequently, assumed to occur more frequently than other letters. 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
