Both notional and grammatical number affect agreement during language production. To explore their workings, we investigated how semantic integration, a type of conceptual relatedness, produces variations in agreement (Solomon & Pearlmutter, 2004). These agreement variations are open to competing notional and lexical-grammatical number accounts. The notional hypothesis is that changes in number agreement reflect differences in referential coherence: More coherence yields more singularity. The lexical-grammatical hypothesis is that changes in agreement arise from competition between nouns differing in grammatical number: More (...) competition yields more plurality. These hypotheses make opposing predictions about semantic integration. On the notional hypothesis, semantic integration promotes singular agreement. On the lexical-grammatical hypothesis, semantic integration promotes plural agreement. We tested these hypotheses with agreement elicitation tasks in two experiments. Both experiments supported the notional hypothesis, with semantic integration creating faster and more frequent singular agreement. This implies that referential coherence mediates the effect of semantic integration on number agreement. (shrink)

Imagine a telephone conversation between a presidential aide and a wealthy supporter, shortly after news breaks that the president plans to veto a bill that the supporter strongly favors. The nervous aide opens with “I'm calling to let you know that the president regrets his, uh, his decision…” The supporter's hopes rise at the intimation that the president changed his mind. But when the aide continues: “… did not meet with your apparel, I mean, your approval,” the crestfallen (and, perhaps, (...) former) supporter realizes that the president is sorry merely about the impact of his decision, not the decision itself. The aide's utterance seems to mean one thing at first, but something entirely different in the end. Unintentional verbal about‐faces of this kind are common in everyday language use – the outspoken owner of an American baseball team recently said that she regretted her remarks offended many people – yet listeners rarely notice the miscues, the wealthy supporter notwithstanding. This is one of the chief motivations behind the psycholinguistic study of language use. (shrink)

Levelt, Roelofs & Meyer present a comprehensive and sophisticated theory of lexical access in production, but we question its reliance on binding-by-checking as opposed to binding-by-timing and we discuss how the timing of retrieval events is a major factor in both correct and errorful production.
