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 so-called "I-algorithm"), as originally recommended and named by LeBel and Gawronski). In her meta-analysis, Hoorens does not recommend a specific algorithm as little is known about how name-letter preference scores obtained from different algorithms relate to the most important psychometric quality of all, validity. The algorithms are typically applied to initials only, but can be used for all name letters. Stieger, Voracek, and Formann recommend that the task be administered twice, that the effects be calculated separately for first-name initial and last-name initial, that the task be accompanied with the birthday-number task, and that the instructions focus on liking rather
