Certain verbs tend to elicit explanations about either their subject or their object. The tendency for one of the verb’s arguments to be rementioned in explanations is known as the implicit causality bias. In this paper we investigate the conditions underlying implicit causality remention biases by means of sentence and story completion studies. On one account of implicit causality, remention biases are the product of a combination of a particular lexico-semantic structure with a causal coherence relation. According to a competing account, the biases arise from a perceived lack of information in the discourse, and thus depend on knowledge about the world and the discourse context. To distinguish between the two accounts, it first needs to be established that information that potentially competes with implicit causality, such as relevant information from the discourse context, can reliably influence remention biases. We provide evidence that a violation of implicit assumptions underlying the standard use of implicit causality verbs leads to different inferences, and an alteration of the remention bias. We thereby lay the groundwork for future studies to distinguish between the two accounts.
