“…This task is a variant of the Stroop (1935) paradigm and has been used successfully to investigate various aspects of lexical access in language production. Several researchers have shown that picture-naming latencies are affected by specific properties of the to-be-ignored word (e.g., Caramazza & Costa, 2000;Glaser & Düngelhoff, 1984;Glaser & Glaser, 1989;Lupker, 1979Lupker, , 1982Posnansky & Rayner, 1977;Rosinski, Golinkoff, & Kukish, 1975;Schriefers, 1993;Schriefers, Meyer, & Levelt, 1990; for reviews, see Glaser, 1992, andMacLeod, 1991). In the experiments reported below, target pictures had to be named in the singular or in the plural.…”
