Refusing to Endorse. A must Explanation for Pejoratives.

In her analysis of pejoratives, Eva Picardi rejects a too sharp separation between descriptive and expressive content. I reconstruct some of her arguments, endorsing Eva’s criticism of Williamson’s analysis of Dummett and developing a suggestion by Manuel Garcia Carpintero on a speech act analysis of pejoratives. Eva’s main concern is accounting for our instinctive refusal to endorse an assertion containing pejoratives because it suggests a picture of reality we do not share. Her stance might be further developed claiming that uses of pejoratives not only suggest, but also promote a wrong picture of reality. Our refusal to endorse implies rejecting not only a wrong picture of reality but also a call for participation to what that picture promotes

Indirect request processing, sentence types and illocutionary forces

According to the literalist view of speech acts, morpho-syntactic sentence types are associated directly at the semantic level with an illocutionary force. By contrast, according to contextualist theories illocutionary force emerges from contexts of use. To date, however, there is little experimental evidence relevant to this debate. We propose two experimental, eye-tracking studies to test two predictions of the literalist view: First, unlike for the highly conventionalised Can you? forms, whenever a non-conventionalised construction such as Is it possible to? is interpreted as a request, its question interpretation should also be activated. Second, the directive interpretation of modal You must declaratives should activate the statement interpretation and, therefore, be costlier than that of imperatives. In Study 1, we show, first, that, in contexts where both the non-directive and directive interpretation of indirect requests are available, the latter are processed as fast as that of the corresponding imperatives, independently of the conventionalisation degree of the indirect request at hand. Second, eye fixation data show that the comprehension of indirect requests does not activate their direct meaning. Study 2 shows that modal You must declaratives are understood as imperatives and do not activate a statement interpretation; this supports the view that obligation modal requests are as direct as imperative requests

An eye-tracking study of selective trust development in children with and without autism spectrum disorder

The purpose of this study was to explore whether children with autism display selectivity in social learning. We investigated the processing of word mappings provided by speakers who differed on previously demonstrated accuracy and on potential degree of reliability in three groups of children (children with autism spectrum disorder, children with developmental language disorder, and typically developing children) aged 4–9 years. In Task 1, one speaker consistently misnamed familiar objects and the second speaker consistently gave correct names. In Task 2, both speakers provided correct information but differed on how they could achieve this accuracy. We analyzed how the speakers’ profiles influenced children's decisions to rely on them in order to learn novel words. We also examined how children attended to the speakers’ testimony by tracking their eye movements and comparing children’ gaze distribution across speakers’ faces and objects of their choice. Results show that children rely on associative trait attribution heuristics to selectively learn from accurate speakers. In Task 1, children in all groups preferred the novel object selected by accurate speakers and directly avoided information provided by previously inaccurate speakers, as revealed by the eye-tracking data. In Task 2, where more sophisticated reasoning about speakers’ reliability was required, only children in the typically developing group performed above chance. Nonverbal intelligence score emerged as a predictor of children's preference for more reliable informational sources. In addition, children with autism exhibited reduced attention to speakers’ faces compared with children in the comparison groups

Context, facial expression and prosody in irony processing

While incongruence with the background context is a powerful cue for irony, in spoken conversation ironic utterances often bear non-contextual cues, such as marked tone of voice and/or facial expression. In Experiment 1, we show that ironic prosody and facial expression can be correctly discriminated as such in a categorization task, even though the boundaries between ironic and non-ironic cues are somewhat fuzzy. However, an act-out task (Experiments 2 & 3) reveals that prosody and facial expression are considerably less reliable cues for irony comprehension than contextual incongruence. Reaction time and eye-tracking data indicate that these non-contextual cues entail a trade-off between accuracy and processing speed. These results suggest that interpreters privilege frugal, albeit less reliable pragmatic heuristics over costlier, but more reliable, contextual processing

Strategic Deception in Adults with Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is often associated with impaired perspective-taking skills. Deception is an important indicator of perspective-taking, and therefore may be thought to pose difficulties to people with ASD (e.g., Baron-Cohen in J Child Psychol Psychiatry 3:1141–1155, 1992). To test this hypothesis, we asked participants with and without ASD to play a computerised deception game. We found that participants with ASD were equally likely—and in complex cases of deception even more likely—to deceive and detect deception, and learned deception at a faster rate. However, participants with ASD initially deceived less frequently, and were slower at detecting deception. These results suggest that people with ASD readily engage in deception but may do so through conscious and effortful reasoning about other people’s perspective

Beyond locutionary denotations: exploring trust between practitioners and policy

This study reports the findings of a research on the trust relationship between practitioners in the Skills for Life (SfL) area and the policy that informs their practice. The exploration of this relationship was premised on an extended notion of trust relationship which draws from the Speech Act theory of Austin (1962; Searle 1969; Kissine 2008), leading to the claim that the existence of different layers of imports in textual analysis makes it possible for a trust relationship to exist between the human/physical and the non human/non physical. The study found that the majority of practitioners in the SfL field trust policy to deliver its inherent policy only to a limited extent. Amongst others, the study identified the impact of the perlocutionary import of policy text on practitioners as a viable reason for this limited level of trust. Such perlocutionary imports, it also found, have adverse impact on practitioners who are considered to have drawn from previous experience to mediate the import of contemporary policies

Is justice blind or myopic? An examination of the effects of meta-cognitive myopia and truth bias on mock jurors and judges

Previous studies have shown that people are truth-biased in that they tend to believe the information they receive, even if it is clearly flagged as false. The truth bias has been recently proposed to be an instance of meta-cognitive myopia, that is, of a generalized human insensitivity towards the quality and correctness of the information available in the environment. In two studies we tested whether meta-cognitive myopia and the ensuing truth bias may operate in a courtroom setting. Based on a well-established paradigm in the truth-bias literature, we asked mock jurors (Study 1) and professional judges (Study 2) to read two crime reports containing aggravating or mitigating information that was explicitly flagged as false. Our findings suggest that jurors and judges are truth-biased, as their decisions and memory about the cases were affected by the false information. We discuss the implications of the potential operation of the truth bias in the courtroom, in the light of the literature on inadmissible and discredible evidence, and make some policy suggestions

Pragmatic reasoning in autism

How does childhood bilingualism and bi-dialectalism affect the interpretation and processing of pragmatic meanings?

AbstractRecent research has reported superior socio-communicative skills in bilingual children. We examined the hypothesis of a bilingual pragmatic advantage by testing bilingual, bi-dialectal and monolingual children on the comprehension and processing of various pragmatic meanings: relevance, scalar, contrastive, manner implicatures, novel metaphors and irony. Pragmatic responses were slower than literal responses to control items. Furthermore, children were least accurate with metaphors and irony. Metaphors and irony were also the most difficult to process; for these meanings, pragmatic responses were slower than literal responses to the same critical items. Finally, pragmatic performance positively correlated with working memory. Despite this variation, we found no bilingual or bi-dialectal advantage over monolinguals in pragmatic responses or speed of pragmatic processing. This was also true despite bilinguals’ and bi-dialectals’ lower vocabularies as measured by formal tests. We conclude that bilingual children exhibit monolingual-like pragmatic interpretation, despite their often-reported weaker language knowledge in the target language.</jats:p
