Speakers can express a critical, dissociative attitude by being ironic. According to the Echoic account of verbal irony, this attitude targets a proposition that echoes a thought attributed to someone other than the speaker herself at the present time. This study investigated the role of echo in irony processing across the lifespan. Through a self-paced reading task, we assessed whether the degree of explicitness of the proposition echoed by the ironical statement and the age of the participant influenced irony processing. (...) Our results show that, independently of age, ironic statements were costlier to process than literal statements, with aging further increasing difficulty. Crucially, our manipulation of the echo affected reading times: it was more complex to process irony when this echoed an implicature or an implicit expectation, particularly for older adults. This work corroborates the role of the echo in verbal irony providing insights into age-related changes in irony processing. (shrink)

Discovering the meaning of novel communicative cues is challenging and amounts to navigating an unbounded hypothesis space. Several theories posit that this problem can be simplified by relying on positive expectations about the cognitive utility of communicated information. These theories imply that learners should assume that novel communicative cues tend to have low processing costs and high cognitive benefits. We tested this hypothesis in three studies in which toddlers (N = 90) searched for a reward hidden in one of several (...) containers. In all studies, an adult communicated the reward's location with an unfamiliar and ambiguous cue. We manipulated the processing costs (operationalized as inferential chain length) and cognitive benefits (operationalized as informativeness) of the possible interpretations of the cues. Toddlers processing of novel communicative cues were guided by expectations of low processing costs (Study 1) and high cognitive benefits (Studies 2 and 3). More specifically, toddlers treated novel cues as if they were easy to process, informative, and accurate, even when provided with repeated evidence to the contrary. These results indicate that, from toddlerhood onward, expectations of cognitive utility shape the processing of novel communicative cues. These data also reveal that toddlers, who are in the process of learning the language and communicative conventions of people around them, exert a pressure favoring cognitive efficiency in communicative systems.

In an ordinary interaction, communicants have various, mostly unconscious goals which reflect their interactional, social and personal needs. In these interactions, people’s minds try to find a balance between reaching these goals and consuming cognitive energy. If a speaker puts too little effort into speech production, she risks not achieving her communicative goals. This is especially typical when the atmosphere is relaxed, a good example of which is family discourse. An analysis of recorded conversations shows that there are certain regular (...) manifestations of risk-taking in family discourse, such as expressing immature thoughts, raising a large variety of topics and overguessing. A substantial amount of risk-taking in family discourse is in one way or another connected with false confidence in the interlocutors’ common ground. Family members know each other well, which results in an overestimation of the similarity of their understanding of words and objects. This attitude leads them to use cryptic, hard-to-comprehend speech. Quick, everyday interactions are mostly automated, and the speakers do not recognise that their speech is full of implicitness and underdeterminacy. (shrink)
