Which normally transitive verbs can omit their objects in English (I ate), and why? This article explores three factors suggested to facilitate object omission: (i) how strongly a verb selects its object (Resnik 1993); (ii) a verb's frequency (Goldberg 2005); (iii) the extent to which the verb is associated with a routine – a recognized, conventional series of actions within a community (Lambrecht & Lemoine 2005; Ruppenhofer & Michaelis 2010; Levin & Rapaport Hovav 2014; Martí 2010, 2015). To operationalize (iii), this article compares the writings of different communities to offer corpus and experimental evidence that verbs omit their objects more readily in the communities in which they are more strongly associated with a routine. More broadly, the article explores how the meaning and syntactic potential of verbs are shaped by the practices of the people who use them.

This study reports a production experiment investigating the realization of objects with different verb types in controlled discourse contexts in 68 three- to seven-year-old sequential Cantonese–English bilingual children. The results show the bilingual children behaved similarly to the Cantonese monolingual peers in object omission, but exhibited protracted development and produced target-deviant forms following a Cantonese pattern in omitting objects specified in prior discourse in English. The bilingual children also showed non-target-like uses of the Cantonese post-verbal object pronoun keoi5, which were unattested in monolingual children. Our findings show evidence for bidirectional cross-linguistic influence: the direction of influence goes from the weaker to the stronger language and from the stronger to the weaker language. Vulnerability of object realization in bilingual acquisition can be better understood in terms of the interaction between cross-linguistic influence, input (e.g., quantity and structural frequencies) and other linguistic elements involved in the interface relation (e.g., verb type).

This article assesses the impact of bilingualism on the acquisition of pronominal direct objects in French and English (clitics in French and strong pronouns in English). We show that, in comparison to monolingual children, bilingual children omit more pronominal objects for a longer period in both languages. At the same time, the development in each language spoken by the bilinguals follows the developmental asymmetry found in the language of their monolingual counterparts: there are more omissions in French than in English. It is also shown that language dominance affects the rate of omissions as there are fewer omissions in the language in which children receive more exposure, i.e. the dominant language. We analyze these results as reflecting a bilingual effect based on the retention of a default null object representation. This in turn is supported by reduced overall input for bilingual children and by language-internal input ambiguity.

We examined the role of schema knowledge in everyday action by assessing the use of unfamiliar implements by patients with subcortical and frontal lobe damage. Although the patients were relatively good at naming or showing how the unfamiliar implements could be used outside of the task context, the patients omitted using the objects in everyday life tasks more often than control participants—either omitting the action step involving the objects or performing the action using a familiar object that was not normally used for this purpose. The data suggest that knowledge about objects in the context of a task can play a determining role in how objects are used in everyday action. In patients with reduced attentional resources, the task schema can over-ride weak bottom-up cueing of action from the objects, with the result that unfamiliar implements are not used.
