Rational accounts of language use such as the uniform information density hypothesis, which asserts that speakers distribute information uniformly across their utterances, and the rational speech act (RSA) model, which suggests that speakers optimize the formulation of their message by reasoning about what the comprehender would understand, have been hypothesized to account for a wide range of language use phenomena. We here specifically focus on the production of discourse connectives. While there is some prior work indicating that discourse connective production (...) may be governed by RSA, that work uses a strongly gamified experimental setting. In this study, we aim to explore whether speakers reason about the interpretation of their conversational partner also in more realistic settings. We thereby systematically vary the task setup to tease apart effects of task instructions and effects of the speaker explicitly seeing the interpretation alternatives for the listener. Our results show that the RSA-predicted effect of connective choice based on reasoning about the listener is only found in the original setting where explicit interpretation alternatives of the listener are available for the speaker. The effect disappears when the speaker has to reason about listener interpretations. We furthermore find that rational effects are amplified by the gamified task setting, indicating that meta-reasoning about the specific task may play an important role and potentially limit the generalizability of the found effects to more naturalistic every-day language use.

Pickering & Garrod's (P&G's) integrated model of production and comprehension includes no explicit role for nonlinguistic cognitive processes. Yet, how domain-general cognitive functions contribute to language processing has become clearer with well-specified theories and supporting data. We therefore believe that their account can benefit by incorporating functions like working memory and cognitive control into a unified model of language processing.

In this paper, we aim to enhance our understanding about the processing of implicit and explicit temporal chronological relations by investigating the roles of temporal connectives and verbal tenses, separately and in interaction. In particular, we investigate how two temporal connectives (ensuiteandpuis, both meaning ‘then’) and two verbal tenses expressing past time (the simple and compound past) act as processing instructions for chronological relations in French. Theoretical studies have suggested that the simple past encodes the instruction to relate events sequentially, (...) unlike the more flexible compound past, which does not. Using an online experiment with a self-paced reading task, we show that these temporal connectives facilitate the processing of chronological relations when they are expressed with both verbal tenses, and that no significant difference is found between the two verbal tenses, nor between the two connectives. By means of an offline experiment with an evaluation task, we find, contrary to previous studies, that comprehenders prefer chronological relations to be overtly marked rather than implicitly expressed, and prefer to use the connectivepuisin particular. Furthermore, comprehenders prefer it when these relations are expressed using the compound past, rather than the simple past. Instead of using thecontinuityhypothesis (Segal et al. 1991,Murray 1997) to explain the processing of temporal relations, we conclude that a more accurate explanation considers a cluster of factors including linguistic knowledge (connectives, tenses, grammatical and lexical aspect) and world knowledge.

Clark highlights a neglected issue in research on language use: the process by which speakers and addressees anchor utterances with respect to individual entities in their common ground. In his review, he identifies the challenges linked to investigations of anchoring, but also displays the pitfalls of evading it.
