Garlic and ginger are not like apples and oranges: Effects of mass/count information on the production of noun phrases in English.

Abstract

In this study a picture-word interference paradigm was used to investigate how grammatical mass/count information is processed during noun phrase production in English. Theories of lexical processing distinguish between two different types of lexical-syntactic information: variable extrinsic lexical-syntactic features, such as number (singular, plural), and fixed intrinsic lexical-syntactic properties, such as grammatical gender (e.g., masculine, feminine). Previous research using the picture-word interference paradigm has found effects of distractor lexical-syntactic congruency for grammatical gender but no congruency effects for number. We used this phenomenon to investigate whether mass/count information is processed similarly to grammatical gender. In two experiments, participants named pictures of mass or count objects using determiner noun phrases (e.g., Experiment 1 with mass and plural count nouns: "not muchmass ricemass", "not manycount pegscount"; Experiment 2 with mass and singular count nouns: "some ricemass", "a pegcount"), while ignoring distractors that were countability congruent or incongruent nouns. The results revealed a countability congruency effect for mass and plural count nouns in Experiment 1 and for singular count nouns, but not mass nouns in Experiment 2. This is similar to grammatical gender suggesting that countability processing is predominantly driven by a noun's lexical-syntactic information.
