Comprehension can be enriched by considering what a speaker could have said but did not; namely, the alternative. For example, "Betty passed some of her exams" can be interpreted as "Betty passed some but not all of her exams". This enriched interpretation is an example of a scalar implicature. We consider whether the salience and use of the alternative are independent processes in the derivation of scalar implicatures or whether use is dependent on salience. Participants completed three sentence interpretation experiments in which the sentences invited scalar implicatures. The experiments used a structural priming paradigm with alternatives and implicatures as primes. We found that (1) adults could be primed to derive scalar implicatures when the alternative was the prime (2) they did so at a rate equal to if the scalar implicature itself were the prime. In the absence of evidence that the use of the alternative can be primed independently of its salience, we conclude that salience and use are not independent processes. Instead, we suggest that when the alternative is sufficiently salient, the implicature will automatically be derived.

Metonymic words have multiple related meanings, such as college, as in the building (“John walked into the college”) or the educational institution (“John was promoted by the college”). Most researchers have found support for direct access models of metonymy but one recent study, Lowder and Gordon (2013), found delayed reading times for metonymic sentences relative to literal controls, in support of an indirect access account. We conducted a speed-accuracy-tradeoff experiment to test whether their result was caused by lower retrieval probabilities, consistent with direct or indirect access models of metonymy, or slower retrieval dynamics, consistent only with indirect access accounts. We found lower retrieval probabilities for the metonymic sentences but no difference in the dynamics parameters. These results therefore suggest that literal senses do not have priority during processing and that established metonymic senses can be accessed directly.

Priming of pragmatic enrichment has been found in behavioural studies. We extend this by examining the neural correlates of priming for two implicature categories, quantifiers and disjunctions. Participants engaged in a primed sentence-picture matching task where they were presented with a sentence (e.g., "some of the letters are Bs") followed by a picture. In prime trials the pictures were either consistent with an enriched interpretation (some but not all) or a basic interpretation (some and possibly all) of the sentence. The pictures in target trials were always consistent with the enriched interpretation. Using ERPs, we found a priming effect on the picture reflected in a reduced positivity for quantifiers when the preceding trial had an enriched interpretation, and no effect for disjunction. The pragmatic priming effect can be dissociated from expectation-based processes. It suggests that abstract derivation processes are primed during pragmatic alignment.

Mindfulness has recently shown promise in mental illness treatment and preventative contexts with school-aged young people. However, there is a shortage of studies investigating the effects of school-based mindfulness interventions on young people of a preadolescent and early-adolescent age. Therefore, the aim of the present study was to investigate the effects of a regional multi-site school-based mindfulness programme on wellbeing and resiliency in UK school children aged 9-12 years old. A total of 1,138 children who received mindfulness training completed the Resiliency Scale for Children and Adolescents and the Stirling Children's Wellbeing Scale pre-and post-intervention. Results showed significant improvements following intervention delivery in positive emotional state, positive outlook, and resiliency, with resiliency effects maintained at a six-month follow-up assessment. Findings indicate that mindfulness delivered by school teachers can improve wellbeing and resiliency in children and young people.

The psychological construct of nature connectedness - the depth of an individual’s relationship with the natural world - has not only been associated with benefits for mental well-being but has also shown relationships with personality traits relevant to the dark personality literature. These include agreeableness, cognitive and affective empathy, and callous and uncaring traits. Across two independently-sampled studies we delineate relationships between explicit and implicit indices of nature connectedness and dark personality. In Study 1 (N = 304), psychopathy (and Machiavellianism) was associated with self-reported, but not implicitly-measured, nature connectedness. Moreover, individuals scoring high on dark personality exhibited a preference for inner-city, relative to suburban or rural living. In Study 2 (N = 209), we replicated the findings of Study 1 in relation to explicit measures of nature connectedness but did not find further relationships between dark personality and the population densities of where participants had previously lived. Limitations of implicit and pseudo indices of nature connectedness are outlined, and the results are discussed in relation to future research and the potential role of nature connectedness interventions in forensic populations.

Conversational partners expect each other to communicate rationally and cooperatively and to contribute relevant and informative utterances. Often however, listeners infer additional meaning over and above the explicit content of an utterance. The present study investigates how speaker characteristics influence inferencing. Experiment 1 (N=205) demonstrates that when produced by knowledgeable speakers utterances such as “the library walls are blue” are more likely to be understood as conveying that the library walls have changed. Experiment 2 (N=205) finds that these inferences are more likely to arise when produced by a speaker who is not typically very chatty; reticent speakers have a higher threshold of what is considered an appropriate conversational contribution. Taken together, the findings from these studies demonstrate that listeners have pervasive expectations of cooperativity and if conversational contributions fail to satisfy this then listeners will engage in sophisticated reasoning to reconcile the mismatch between expectations and input.
