EXPRESS: Experimental evidence for a semantic typology of emoji: Inferences of co-, pro-, and post-text emoji.

Emoji symbols are widely used in online communication, particularly in instant messaging and on social media platforms. Existing research draws comparisons between the functions of emoji and those of gestures, with recent work extending a proposed typology of gestures to emoji, arguing that different emoji types can be distinguished by their placement within the modified text and by their semantic contribution (the linguistic inferences that they give rise to). In this paper, we present four experiments designed to test the predictions of this extended typology, the results of which suggest that emoji symbols indeed trigger the hypothesized linguistic inferences. The findings provide support for a semantic typology of emoji and contribute further evidence of the parallels between gesture and emoji.

Social media use by young people with language disorders: a scoping review.

PURPOSE: Social media are widely used by young people (YP), but how YP with language disorders use social media for social interaction remains insufficiently studied. This article provides an overview of the research on social media use by YP with language disorders. MATERIALS AND METHODS: A scoping review was conducted, guided by a five-stage framework. Ten databases were searched (CENTRAL, CINAHL, ERIC, LLBA, Medline, PsychINFO, Scopus, speechBITE, Web of Science, ProQuest Dissertations & Theses Global). Chaining searches of papers identified for inclusion were conducted. RESULTS: After screening 199 unique papers, 44 were included. Findings revealed that YP with language disorders use social media less compared to typically developing peers; their profile of communication difficulties may impact the types of social media with which they engage. Although intervention studies are limited, the results offer encouraging findings regarding the positive impact of support for use of social media. Barriers and facilitators for social media use are identified. CONCLUSIONS: YP with language disorders use social media for social purposes. However, co-designed research into what YP with language disorders perceive their social media needs to be is urgently needed. How to support YP with language disorders to use social media is subject to future investigation.

Young people with language disorders are likely using a range of social media to support their social participation, but they use social media less than typically developing peers.The types of social media young people with language disorders choose to engage with may be impacted by their language/literacy difficulties.There is preliminary evidence that intervention to support the use of social media by young people with language disorders is beneficial, but more research is required to identify the components to include in social media use training programs.To support the access to and use of social media by young people with language disorders, healthcare professionals may need to collaborate with parents and schools.

Do speech-language therapists support young people with communication disability to use social media? A mixed methods study of professional practices.

BACKGROUND: Social media is increasingly used by young people, including those with communication disability. To date, though, little is known about how speech-language therapists (SLTs) support the social media use of young people with communication disability. AIMS: To explore what services SLTs provide to facilitate the social media use of young people with communication disability, including what these services look like, and the factors that impact SLTs' professional practices. METHODS & PROCEDURES: A sequential mixed methods approach was employed including an online survey and in-depth semi-structured interviews. Participants were qualified practising SLTs in Australia with a caseload that included clients aged 12-16 years. Quantitative data were analysed with SPSS. A thematic analysis of qualitative data was conducted with NVivo. OUTCOMES & RESULTS: Survey responses from 61 SLTs were analysed. Interviews were conducted with 16 participants. Survey data indicated that SLTs do not systematically assess or treat young people's use of social media as part of their professional practice. Interview data revealed that where SLTs do support young people's use of social media, they transfer knowledge and practices typically used in offline contexts to underpin their work supporting clients' use of social media. In terms of factors that affect SLTs' practices, three major themes were identified: client/family factors, SLT factors, and societal factors. CONCLUSIONS & IMPLICATIONS: While young people with communication disability may desire digital participation in social media spaces, SLTs' current professional practices do not routinely address this need. Professional practice guidelines would support SLTs' practices in this area. Future research should seek the opinions of young people with communication disability regarding their use of social media, and the role of SLTs in facilitating this. WHAT THIS PAPER ADDS: What is already known on the subject Young people with communication disability use social media, but digital inequality means that they may not do so to the same extent as their typically developing peers. Services targeting a young person's social media use is within the SLT scope of practice. Whether or not SLTs routinely address the social media use of young people with communication disability as part of their professional practice is unknown. What this study adds to existing knowledge This study found that SLTs in Australia do not systematically provide professional services targeting young people's use of social media. When services do address a young person's use of social media, knowledge and practices typically used by SLTs in offline contexts are adapted to support their work targeting online social media contexts. What are the potential or actual clinical implications of this work? This study indicates that SLTs should consider a range of factors when deciding whether to address a young person's social media use. Adapting existing offline professional practices to online environments could support SLTs' work in providing services targeting social media use. Professional practice guidelines would support SLTs' work facilitating the social media use of young people with communication disability.

Co-linguistic content inferences: From gestures to sound effects and emoji.

Among other uses, co-speech gestures can contribute additional semantic content to the spoken utterances with which they coincide. A growing body of research is dedicated to understanding how inferences from gestures interact with logical operators in speech, including negation ("not"/"n't"), modals (e.g., "might"), and quantifiers (e.g., "each," "none," "exactly one"). A related but less addressed question is what kinds of meaningful content other than gestures can evince this same behaviour; this is in turn connected to the much broader question of what properties of gestures are responsible for how they interact with logical operators. We present two experiments investigating sentences with co-speech sound effects and co-text emoji in lieu of gestures, revealing a remarkably similar inference pattern to that of co-speech gestures. The results suggest that gestural inferences do not behave the way they do because of any traits specific to gestures, and that the inference pattern extends to a much broader range of content.

Clinical practices of speech-language pathologists working with 12- to 16-year olds in Australia.

Purpose: The current landscape of speech-language pathology (SLP) services for 12- to 16-year olds in Australia remains largely unchartered. Implementing the Speech Pathology 2030 vision necessitates mapping current services, and gaps in services, provided by speech-language pathologists (SLPs). However, the last survey of Australian SLPs' practices with young people was conducted in 2005. The aim of this study was to bridge the service delivery information gap.Method: Ninety-six SLPs working with 12- to 16-year olds in Australia completed an anonymous online survey consisting of binary choice, multiple choice, and Likert scale questions. A theoretical approach to service delivery based on response to intervention models underpinned question design.Result: SLP clinical practices remain traditional, following an impairment/diagnostic model. Additionally, there is an inequitable provision of SLP services across states/territories of Australia, according to whether or not there is government provision for SLP services in public schools.Conclusion: The results suggest a need for standard government provision of SLP services across Australia to ensure equity of access. These findings inform our understanding of contemporary assessment and intervention practices of SLPs working with 12- to 16-year olds in Australia.

Testing theories of plural meanings.

Plural morphology in English is associated with a multiplicity inference. For example, "Emily fed giraffes" is typically interpreted to mean that Emily fed multiple giraffes. It has long been observed that this inference disappears in downward-entailing linguistic environments, such as in the scope of negation. For example, "Emily didn't feed giraffes" does not merely suggest that she didn't feed multiple giraffes, but rather that she didn't feed any. There are three main approaches to explaining this puzzle: the first proposes that the plural is ambiguous, and invokes a preference for stronger meanings; the second derives multiplicity inferences as implicatures; and the third provides a homogeneity-based account. These different approaches can all account for the interpretation of the plural across upward- and downward-entailing environments. They differ, however, in what they predict for three further aspects of the plural: the status of positive and negative plural sentences in singular contexts, children's acquisition of plural meanings, and the relationship between plural meanings and scalar implicatures. In this paper, we report on three experiments investigating adults' and preschool-aged children's interpretation of plural morphology in English. The experiments reveal that participants distinguish positive and negative plural sentences presented in singular contexts, and that adults assign a different status to these positive and negative sentences. It is also observed that children, unlike adults, tend to accept underinformative positive plural sentences in singular contexts - in parallel with their behavior on standard scalar implicatures - while they are relatively more adult-like when it comes to negative plural sentences in the same contexts, showing a tendency to reject the negative sentences. We discuss how the findings of the three experiments are expected on a scalar implicature approach to multiplicity inferences, and the open challenges they pose for the ambiguity and homogeneity approaches.

Children's Acquisition of Homogeneity in Plural Definite Descriptions.

Plural definite descriptions give rise to homogeneity effects: the positive The trucks are blue and the negative The trucks aren't blue are both neither true nor false when some of the trucks are blue and some are not, that is, when the group of trucks is not homogeneous with respect to the property of being blue (Löbner, 1987, 2000; Schwarzschild, 1994; Kriz, 2015b). The only existing acquisition studies related to the phenomenon have examined children's comprehension only of the affirmative versions of such sentences, and moreover have yielded conflicting data; while one study reports that preschoolers interpret definite plurals maximally (Munn et al., 2006, see also Royle et al., 2018), two other studies report that preschoolers allow non-maximal interpretations of definite plurals where adults do not (Karmiloff-Smith, 1979; Caponigro et al., 2012). Moreover, there is no agreed upon developmental trajectory to adult homogeneity. In this paper, we turn to acquisition data to investigate the predictions of a recent analysis of homogeneity that treats homogeneous meanings as the result of a scalar implicature (Magri, 2014). We conducted two experiments targeting 4- and 5-year-old French-speaking children's interpretations of plural definite descriptions in positive and negative sentences, and tested the same children on standard cases of scalar implicature. The experiments revealed three distinct subgroups of children: those who interpreted the plural definite descriptions existentially and failed to compute implicatures; those who both accessed homogeneous interpretations and computed implicatures; and finally, a smaller subgroup of children who appeared to access homogeneous interpretations without computing implicatures. We discuss the implications of our findings, which appear to speak against the implicature theory as the adult-like means of generating homogeneous meanings.

Linguistic inferences without words.

Contemporary semantics has uncovered a sophisticated typology of linguistic inferences, characterized by their conversational status and their behavior in complex sentences. This typology is usually thought to be specific to language and in part lexically encoded in the meanings of words. We argue that it is neither. Using a method involving "composite" utterances that include normal words alongside novel nonlinguistic iconic representations (gestures and animations), we observe successful "one-shot learning" of linguistic meanings, with four of the main inference types (implicatures, presuppositions, supplements, homogeneity) replicated with gestures and animations. The results suggest a deeper cognitive source for the inferential typology than usually thought: Domain-general cognitive algorithms productively divide both linguistic and nonlinguistic information along familiar parts of the linguistic typology.

On children's variable success with scalar inferences: Insights from disjunction in the scope of a universal quantifier.

Previous developmental studies have revealed variation in children's ability to compute scalar inferences. While children have been shown to struggle with standard scalar inferences (e.g., with scalar quantifiers like "some") (Chierchia, Crain, Guasti, Gualmini, & Meroni, 2001; Guasti et al., 2005; Noveck, 2001; Papafragou & Musolino, 2003), there is also a growing handful of inferences that children have been reported to derive quite readily (Barner & Bachrach, 2010; Hochstein, Bale, Fox, & Barner, 2016; Papafragou & Musolino, 2003; Singh, Wexler, Astle-Rahim, Kamawar, & Fox, 2016; Stiller, Goodman, & Frank, 2015; Tieu, Romoli, Zhou, & Crain, 2016; Tieu et al., 2017). One recent approach, which we refer to as the Alternatives-based approach, attributes the variability in children's performance to limitations in how children engage with the alternative sentences that are required to compute the relevant inferences. Specifically, if the alternative sentences can be generated by simplifying the assertion, rather than by lexically replacing one scalar term with another, children should be better able to compute the inference. In this paper, we investigated this prediction by assessing how children and adults interpret sentences that embed disjunction under a universal quantifier, such as "Every elephant caught a big butterfly or a small butterfly". For adults, such sentences typically give rise to the distributive inference that some elephant caught a big butterfly and some elephant caught a small butterfly (Crnic, Chemla, & Fox, 2015; Fox, 2007; Gazdar, 1979). Another possible interpretation, though not one typically accessed by adults, is the conjunctive inference that every elephant caught a big butterfly and a small butterfly (Singh, Wexler, Astle-Rahim, Kamawar, & Fox, 2016). Crucially, for our purposes, it has been argued that both of these inferences can be derived using alternatives that are generated by deleting parts of the asserted sentence, rather than through lexical replacement, making these sentences an ideal test case for evaluating the predictions of the Alternatives-based approach. The findings of our experimental study reveal that children are indeed able to successfully compute this class of inferences, providing support for the Alternatives-based approach as a viable explanation of children's variable success in computing scalar inferences.

Children's comprehension of plural predicate conjunction.

Previous developmental studies of conjunction have focused on the syntax of phrasal and sentential coordination (Lust, 1977; de Villiers, Tager-Flusberg & Hakuta, 1977; Bloom, Lahey, Hood, Lifter & Fiess, 1980, among others). The present study examined the flexibility of children's interpretation of conjunction. Specifically, when two predicates that can apply simultaneously to a single individual are conjoined in the scope of a plural definite (The bears are big and white), conjunction receives a Boolean, intersective interpretation. However, when the conjoined predicates cannot apply simultaneously to an individual (The bears are big and small), conjunction receives a weaker 'split' interpretation (Krifka, 1990; Lasersohn, 1995; Winter, 1996). Our experiments reveal that preschool-aged children are sensitive to both intersective and split interpretations, and can use their lexical and world knowledge of the relevant predicates in order to select an appropriate reading.

English-speaking preschoolers can use phrasal prosody for syntactic parsing.

This study tested American preschoolers' ability to use phrasal prosody to constrain their syntactic analysis of locally ambiguous sentences containing noun/verb homophones (e.g., [The baby flies] [hide in the shadows] vs [The baby] [flies his kite], brackets indicate prosodic boundaries). The words following the homophone were masked, such that prosodic cues were the only disambiguating information. In an oral completion task, 4- to 5-year-olds successfully exploited the sentence's prosodic structure to assign the appropriate syntactic category to the target word, mirroring previous results in French (but challenging previous English-language results) and providing cross-linguistic evidence for the role of phrasal prosody in children's syntactic analysis.
