Interference in a typeface variant of the Stroop test

Ss were asked to name the typeface in which a printed item appeared in a discrete trial variant of the Stroop color-word test. Two kinds of items were used: (a) typeface names appearing in antagonistic typefaces, e.g., the word SCRIPT printed in bold type; and (b) nonsense strings constructed by jumbling; the letters in a typeface name, e.g., PSRTCI printed in bold type. Typeface-naming latencies were found to be significantly longer for items of the first kind. Examination of the distributions of individual trial latencies for the two kinds of items indicated that modification of Morton’s (1969) account of the Stroop test is required.
