Cosa avviene quando coscienze linguistiche distinte, oltre ad essere separate dall’epoca, dall’area geografica di provenienza o dalla differenziazione sociale, dalle diverse dimensioni linguistiche, appartengono anche a domini semiotici diversi? È quel che accade ogni volta che comunichiamo in rete, l’interazione digitale è infatti l’ambito di comunicazione ibrido per eccellenza: in esso alla mescolanza di lingue diverse si sovrappone la mescolanza di codici diversi. Partendo dal presupposto che siano i nuovi bisogni espressivi e le nuove situazioni comunicative a spingere verso le innovazioni linguistiche, sembra dunque interessante tener conto del rilievo assunto dal repertorio visuale – e più in generale multimodale – nell’uso spontaneo dei nuovi media e constatare come le particolari strategie di costruzione del significato attualmente in atto non possano ormai più prescindere da queste seconde dimensioni. Del loro peso nell’uso digitale della lingua è bene avere consapevolezza per affrontare senza pregiudizi tutte le novità ad essa connesse. Un ruolo di centrale importanza nell’approccio al linguaggio verbale in Internet è legato alla funzione indessicale della lingua che, unito alla presenza di un archivio di riferimento di conoscenze del mondo condiviso, innesca un nuovo tipo d’inferenzialità nel ricevente. La conversazione attraverso i social network consente infatti azioni che non necessariamente sono presenti nello scambio vis-a-vis, ma che invece sono peculiari di Facebook, Twitter, G+, Instagram, Flickr e in generale dei social network: la condivisione di materiale multimediale di vario genere, l’opzione di richiamare i messaggi relativi a un tema specifico e la possibilità di glossarlo. Il materiale multimediale diventa così al tempo stesso parte integrante della comunicazione e modalità espressiva, focus del discorso e linguaggio metaforico condiviso. Questo lavoro di ricerca indaga come ambiti di ricerca diversi, e apparentemente distanti fra loro, possano interagire produttivamente con il panorama scientifico delle scienze del linguaggio, dell’immagine e della comunicazione, giungendo alla formulazione di un modello aggiornato dell'ibridazione linguistica che caratterizza la comunicazione in rete.
A large body of research now supports the presence of both syntactic and lexical predictions in sentence processing. Lexical predictions, in particular, are considered to indicate a deep level of predictive processing that extends past the structural features of a necessary word (e.g. noun), right down to the phonological features of the lexical identity of a specific word (e.g. /kite/; DeLong et al., 2005). However, evidence for lexical predictions typically focuses on predictions in very local environments, such as the adjacent word or words (DeLong et al., 2005; Van Berkum et al., 2005; Wicha et al., 2004). Predictions in such local environments may be indistinguishable from lexical priming, which is transient and uncontrolled, and as such may prime lexical items that are not compatible with the context (e.g. Kukona et al., 2014). Predictive processing has been argued to be a controlled process, with top-down information guiding preactivation of plausible upcoming lexical items (Kuperberg & Jaeger, 2016). One way to distinguish lexical priming from prediction is to demonstrate that preactivated lexical content can be maintained over longer distances.
In this dissertation, separable German particle verbs are used to demonstrate that preactivation of lexical items can be maintained over multi-word distances. A self-paced reading time and an eye tracking experiment provide some support for the idea that particle preactivation triggered by a verb and its context can be observed by holding the sentence context constant and manipulating the predictabilty of the particle. Although evidence of an effect of particle predictability was only seen in eye tracking, this is consistent with previous evidence suggesting that predictive processing facilitates only some eye tracking measures to which the self-paced reading modality may not be sensitive (Staub, 2015; Rayner1998). Interestingly, manipulating the distance between the verb and the particle did not affect reading times, suggesting that the surprisal-predicted faster reading times at long distance may only occur when the additional distance is created by information that adds information about the lexical identity of a distant element (Levy, 2008; Grodner & Gibson, 2005). Furthermore, the results provide support for models proposing that temporal decay is not major influence on word processing (Lewandowsky et al., 2009; Vasishth et al., 2019).
In the third and fourth experiments, event-related potentials were used as a method for detecting specific lexical predictions. In the initial ERP experiment, we found some support for the presence of lexical predictions when the sentence context constrained the number of plausible particles to a single particle. This was suggested by a frontal post-N400 positivity (PNP) that was elicited when a lexical prediction had been violated, but not to violations when more than one particle had been plausible. The results of this study were highly consistent with previous research suggesting that the PNP might be a much sought-after ERP marker of prediction failure (DeLong et al., 2011; DeLong et al., 2014; Van Petten & Luka, 2012; Thornhill & Van Petten, 2012; Kuperberg et al., 2019). However, a second experiment in a larger sample experiment failed to replicate the effect, but did suggest the relationship of the PNP to predictive processing may not yet be fully understood. Evidence for long-distance lexical predictions was inconclusive.
The conclusion drawn from the four experiments is that preactivation of the lexical entries of plausible upcoming particles did occur and was maintained over long distances. The facilitatory effect of this preactivation at the particle site therefore did not appear to be the result of transient lexical priming. However, the question of whether this preactivation can also lead to lexical predictions of a specific particle remains unanswered. Of particular interest to future research on predictive processing is further characterisation of the PNP. Implications for models of sentence processing may be the inclusion of long-distance lexical predictions, or the possibility that preactivation of lexical material can facilitate reading times and ERP amplitude without commitment to a specific lexical item.
Argumentation mining is a subfield of Computational Linguistics that aims (primarily) at automatically finding arguments and their structural components in natural language text. We provide a short introduction to this field, intended for an audience with a limited computational background. After explaining the subtasks involved in this problem of deriving the structure of arguments, we describe two other applications that are popular in computational linguistics: sentiment analysis and stance detection. From the linguistic viewpoint, they concern the semantics of evaluation in language. In the final part of the paper, we briefly examine the roles that these two tasks play in argumentation mining, both in current practice, and in possible future systems.
The paper investigates Turkish texts from heritage speakers of Turkish in Germany in a pseudo-longitudinal setting, looking at pupils' texts from the 5th, 7th, 10th and 12th grades. Two types of dynamics are identified in the advanced acquisition(1) of Turkish orthography in the heritage context. One is the dynamic of language contact, where in certain areas of the orthography, we find a re-interpretation of Turkish principles according to the German model. However, this changes as the pupils grow up. The second dynamic is the heritage situation. The heritage situation on one side leads to the establishment of new practices, and it also leads to a higher degree of variability of spelling solutions in those areas, where the orthographic system of Turkish poses challenges to every writer, whether monolingual and growing up in Turkey or heritage speaker.
This study is the first to use kinematic data to assess lingual carryover coarticulation in children. We investigated whether the developmental decrease previously attested in anticipatory coarticulation, as well as the relation between coarticulatory degree and the consonantal context, also characterize carryover coarticulation. Sixty-two children and 13 adults, all native speakers of German, were recruited according to five age cohorts: three-year-olds, four-year-olds, five-year-olds, seven-year-olds, and adults. Tongue movements during the production of ə.CV.Cə utterances (C = /b, d, g/, V = /i, y, e, a, o, u/) were recorded with ultrasound. We measured vowel-induced horizontal displacement of the tongue dorsum within the last syllable and compared the resulting coarticulatory patterns between age cohorts and consonantal contexts. Results indicate that the degree of vocalic carryover coarticulation decreases with age. Vocalic prominence within an utterance as well as its change across childhood depended on the postvocalic consonant’s articulatory demands for the tongue dorsum (i.e., its coarticulatory resistance): Low resistant /b/ and /g/ allowed for more vocalic perseveration and a continuous decrease, while the highly resistant /d/ displayed lower coarticulation degrees and discontinuous effects. These findings parallel those in anticipation suggesting a similar organization of anticipatory and carryover coarticulation. Implications for theories of speech production are discussed.

Elicitation materials like language portraits are useful to investigate people's perceptions about the languages that they know. This study uses portraits to analyse the underlying conceptualisations people exhibit when reflecting on their language repertoires. Conceptualisations as manifestations of cultural cognition are the purview of cognitive sociolinguistics. The present study advances portrait methodology as it analyses data from structured language portraits of 105 South African youth as a linguistic corpus from both qualitative and quantitative perspectives. The approach enables the uncovering of (a) prominent underlying conceptualisations of African language(s) and the body, and (b) the differences and similarities of these conceptualisations vis-a-vis previous cognitive (socio) linguistic studies of embodied language experiences. In our analysis, African home languages emerged both as 'languages of the heart' linked to cultural identity and as 'languages of the head' linked to cognitive strength and control. Moreover, the notion of 'degrees of proficiency' or 'magnitude' of language knowledge emerged more prominently than in previous studies of embodied language experience.
Stressful events affect mnemonic processing, in particular for emotionally arousing events. Previous research on the mechanisms underlying stress effects on human memory focused on stress-induced changes in the neural activity elicited by a stimulus. We tested an alternative mechanism and hypothesized that stress may already alter the neural context for successful memory formation, reflected in the neural activity preceding a stimulus. Therefore, 69 participants underwent a stress or control procedure before encoding neutral and negative pictures. During encoding, we recorded high-density EEG and analyzed-based on multivariate searchlight analyses-oscillatory activity and cross-frequency coupling patterns before stimulus onset that were predictive of memory tested 24 hr later. Prestimulus theta predicted subsequent memory in controls but not in stressed participants. Instead, prestimulus gamma predicted successful memory formation after stress, specifically for emotional material. Likewise, stress altered the patterns of prestimulus theta-beta and theta-gamma phase-amplitude coupling predictive of subsequent memory, again depending on the emotionality of the presented material. Our data suggest that stress changes the neural context for building new memories, tuning this neural context specifically to the encoding of emotionally salient events. These findings point to a yet unknown mechanism through which stressful events may change (emotional) memory formation.
El presente estudio revela elementos lingüísticos que existen entre dos variedades del español y determina en qué medida estos aportes son relevantes para la enseñanza del español como lengua extranjera. Por medio de un contraste lingüístico de textos audiovisuales entre dos cortometrajes auténticos, provenientes de México y España y bajo la temática del fenómeno social del bullying, se hizo un análisis comparativo entre los resultados del contraste. El objetivo principal es evidenciar combinaciones sintácticas, elementos léxicos, pragmáticos y semánticos que existen entre las distintas formas de expresión de las dos hablas. Los resultados obtenidos muestran componentes significantes de la lengua, que confirman la importancia de tratar el tema de las variedades del español en el aula, desde una perspectiva tanto didáctica como socio-cultural.
Debates on the relevance of repatriation of indigenous human remains are water under the bridge today. Yet, a genuine will for dialogue to work through colonial violence is found lacking in the European public sphere. Looking at local remembrance of the Majimaji War (1905-07) in the south of Tanzania and a German-Tanzanian theatre production, this article demonstrates how the spectre of colonial headhunting stands at the heart of claims for repatriation and acknowledgement of this anti-colonial movement. The missing head of Ngoni leader Songea Mbano haunts the future of German-Tanzanian relations in culture and heritage. By staging the act of post-mortem dismemberment and foregrounding the perspective of descendants, the theatre production Maji Maji Flava offers an honest proposal for dealing with stories of sheer colonial violence in transnational memory.
