ABSTRACT
In discourses involving implicit causality, the implicit cause of the event is referentially predictable, that is, it is likely to be rementioned. However, it is unclear how referential predictability is calculated. We test two possible explanations: (1) The frequency account suggests that people learn that implicit causes are predictable through experience with the most frequent patterns of reference in natural language, and (2) the topicality account asks whether implicit causes tend to play topical roles in the discourse, which itself may lead to the perception of discourse accessibility. With two text analyses we show that implicit causes are frequently rementioned, but only if we consider a narrow set of discourse circumstances, which would require comprehenders to track contingent frequencies. We found no evidence for the topicality account: in two experiments, implicit causality affected predictability but not topicality, and in a corpus of natural speech, implicit causes tended to not occupy topical positions.

Notes
1. It is also well established that comprehension is facilitated by the predictive activation of sounds, words, and syntactic structures (inter alia Coulson et al., Citation2005; Falkauskas & Kuperman, Citation2015; Federmeier & Kutas, Citation2001; Kochari & Flecken, Citation2019; Kowalski & Huang, Citation2017; Kutas & Hillyard, Citation1984; Levy, Citation2008; Pickering & Garrod, Citation2007; Ryskin et al., Citation2019; Smith & Levy, Citation2013; Viebahn et al., Citation2015).
2. For a similar question based on the role of connector words, see Mak et al. (Citation2013).
3. This is comparable to the analysis in Arnold (Citation2001), which included 174 tokens.
4. But see for example, Koornneef and Sanders (Citation2013), Experiment 2; Majid et al. (Citation2006), and Van den Hoven and Ferstl (Citation2018) for a similar stimulus feature.
