Studies of the Efficiency of Drug Labelling
Main Article Content
Abstract
Two experiments on the effectiveness of drug-labelling are reported. The first compared typewritten with hand-written labels, and the second compared printed drug-labels varying in type size, form of type, and layout (centered or ranged left). A discrimination-test procedure was employed, the subjects having to select specified labels from a display. T he results of the experiments showed (I) that typewritten labels were discriminated more readily than handwritten ones, (2) that labels printed with 10-point type were discriminated more speedily than labels printed with 6-point type, (3) that for labels printed with 6-point type, upper-case letterform was more easily d iscriminated than lower-case le tterform, (4) the layout of the label design had no effect on discrimination.
