Much work has shown that differences in the timecourse of language processing are central to comparing native (L1) and non-native (L2) speakers. However, estimating the onset of experimental effects in timecourse data presents several statistical problems including multiple comparisons and autocorrelation. We compare several approaches to tackling these problems and illustrate them using an L1-L2 visual world eye-tracking dataset. We then present a bootstrapping procedure that allows not only estimation of an effect onset, but also of a temporal confidence interval around this divergence point. We describe how divergence points can be used to demonstrate timecourse differences between speaker groups or between experimental manipulations, two important issues in evaluating L2 processing accounts. We discuss possible extensions of the bootstrapping procedure, including determining divergence points for individual speakers and correlating them with individual factors like L2 exposure and proficiency.

Purpose:
This study examines the contribution of number morphology to language comprehension abilities among children with specific language impairment (SLI) and age-matched controls. It addresses the question of whether number agreement facilitates the comprehension accuracy of object-initial declarative sentences. According to the predictions of the structural intervention account for German, number agreement should assist the correct interpretation of object-initial sentences.
Method:
This study examines German-speaking children with SLI and a control group of age-matched typically developing children on their sentence comprehension skills for auditory presented subject-verb-object and object-verb-subject (OVS) sentences. The sentences were manipulated with respect to the number properties of the noun phrases (e.g., one plural and one singular, or both singular) and the number agreement of the verb.
Results:
The group of children with SLI demonstrated poorer comprehension accuracy in comparison to controls. Comprehension difficulty was limited to OVS sentences among children with SLI. In addition, children with SLI comprehended OVS sentences in which number agreement (with plural subject and verb inflection) indicated the noncanonical word order more accurately than OVS sentences with two singular noun phrases and therein did not differ from controls.
Conclusion:
The study suggests that number agreement helps alleviate the difficulty with OVS sentences and enhances comprehension accuracy, despite the finding that children with SLI exhibit lower comprehension accuracy and more heterogeneous interindividual differences, relative to controls.
This study examines language ideologies and communicative practices in the multilingual Vaupes region of northwestern Amazonia. Following a comparative overview of the Vaupes as a 'small-scale' language ecology, it discusses claims from existing ethnographic work on the region in light of data from a corpus of video-recordings of sociolinguistic interviews and spontaneous everyday conversations. It shows how a practice-based and interdisciplinary approach combining language documentation methodology and ethnographic, structural linguistic, and interactional perspectives can contribute to understanding of macro and micro aspects of multilingualism, thus contributing to future work on the Vaupes, typologies of small-scale multilingual ecologies, and language contact research.
A grammar of authority?
(2021)
Directive Speech Acts (dsas) are a major feature of historical pragmatics, specifically in research on historical (im)politeness. However, for Classical French, there is a lack of research on related phenomena. In our contribution, we present two recently constructed corpora covering the period of Classical French, sermo and apwcf. We present these corpora in terms of their genre characteristics on a communicative-functional and socio-pragmatic level. Based on the observation that, both in sermo and apwcf, dsas frequently occur together with terms of address, we analyse and manually code a sample based on this co-occurrence, and we compare the results with regard to special features in the individual corpora. The emerging patterns show a clear correspondence between socio-pragmatic factors and the linguistic means used to realise dsas. We propose that these results can be interpreted as signs of an underlying "grammar of authority".
Strings of words can correspond to more than one interpretation or underlying structure, which makes them ambiguous. Prosody can be used to resolve this structural ambiguity. This dissertation investigates the use of prosodic cues in the domains of fundamental frequency (f0) and duration to disambiguate between two interpretations of ambiguous structures when speakers addressed different interlocutors. The dissertation comprises of three production studies and one comprehension study.
Prosodic disambiguation was studied with a focus on German name sequences of three names (coordinates) in two conditions: without (Name1 and Name2 and Name3) and with internal grouping of the first two names ([Name1 and Name2] and Name3). The study of coordinates was complemented with production data of locally ambiguous sentences with a case-ambiguous first noun phrase.
Variability was studied in a controlled setting: Productions were elicited with a within-subject manipulation of context in a referential communication task in order to evoke prosodic adaptations to different conversational contexts. Context had five levels and involved interlocutors in three age groups (child, young adult, elderly adult) with German as L1 in the absence of background white noise, the young adult with background white noise, and a young adult without German as L1. Variability was explored at different levels: within a group of young individuals (intra-group level), within and between young individuals (intra-individual level and inter-individual level, respectively), and comparing between the group of young and a group of older speakers (inter-group level).
Our data replicate the use of the three prosodic cues (f0-movement, final lengthening, and pause) in productions of young adult speakers and extend their use to productions of older adult speakers. Both age groups distinguished consistently between the two coordinate conditions. Prosodic grouping in production was evident not only on the group-final Name2 but also at earlier stages in the utterance, on the group-internal Name1 (early cues). For some speakers, some listeners were able to decode these early cues effectively as they were able to reliably predict the upcoming structure after listening to Name1 only. Thus, prosodic grouping appears as a globally marked phenomenon building up along the utterance. The internal structure of coordinates was disambiguated irrespective of the conversational context. In our data, speakers only slightly modified the prosodic cues marking the disambiguation in the different contexts. Listeners were unable to identify to which interlocutor the sequence had been produced. We interpret this intra-individual consistency in the production of disambiguating prosodic cues as support for a strong link between prosody and syntax. The findings support models in favour of situational independence of disambiguating prosody. All speakers reliably marked the distinction between the grouping conditions with at least one of the three prosodic cues investigated and most of the speakers used at least two of these cues. Further, individual differences in prosodic grouping did not lead to difficulties in recovering the grouping in comprehension. Taken together, these findings support the existence of a phonological category of prosodic grouping.
Converbs in heritage Turkish
(2021)
Turkish expresses adverbial subordination predominantly by means of converb clauses. These are headed by nonfinite verbs, i.e. converbs, which have a converb suffix attached to the stem. The different converbs express different aspectual relations between the subordinate and the superordinate clause, and they can be modifying or non-modifying. We analyse data from speakers of Turkish as a heritage language in Germany and the U.S. as well as monolingual speakers of Turkish in Turkey. The data come from two age groups: adults and adolescents. We show that unlike in canonical Turkish, converbs in heritage Turkish can be multifunctional, meaning that they can express both simultaneity and causality, for example. Furthermore, we show that converbs in heritage Turkish can be both modifying and non-modifying. As possible factors which might be responsible for such variation, we discuss language contact, sociolinguistic differences between the speaker communities (Germany vs. the U.S.) and age of the speakers.
Spatiotemporal coordination in word-medial stop-lateral and s-stop clusters of American English
(2021)
This paper is concerned with the relation between syllabic organization and intersegmental spatiotemporal coordination using Electromagnetic Articulometry recordings from seven speakers of American English (henceforth, English). Whereas previous work on English has focused on word-initial clusters (preceding a vowel whose identity was not systematically varied), the present work examined word-medial clusters /pl, kl, sp, sk/ in the context of three different vowel heights (high, mid, low). Our results provide evidence for a global organization for the segments involved in these cluster-vowel combinations. This is reflected in a number of ways: compression of the prevocalic consonant and reduction of CV timing in the word-medial cluster case compared to its singleton paired word in both stop-lateral and s-stop clusters, early vowel initiation (as permitted by the clusters' phonetic properties), and presence of compensatory relations between phonetic properties of different segments or intersegmental transitions within each cluster. In other words, we find that the global organization presiding over the segments partaking in these word-medial tautosyllabic CCVs is pleiotropic, that is, simultaneously expressed in multiple phonetic exponents rather than via a privileged metric such as c-center stability or any other such given single measure employed in previous works.
Looking times and gaze behavior indicate that infants can predict the goal state of an observed simple action event (e.g., object-directed grasping) already in the first year of life. The present paper mainly focuses on infants' predictive gaze-shifts toward the goal of an ongoing action. For this, infants need to generate a forward model of the to-be-obtained goal state and to disengage their gaze from the moving agent at a time when information about the action event is still incomplete. By about 6 months of age, infants show goal-predictive gaze-shifts, but mainly for familiar actions that they can perform themselves (e.g., grasping) and for familiar agents (e.g., a human hand). Therefore, some theoretical models have highlighted close relations between infants' ability for action-goal prediction and their motor development and/or emerging action experience. Recent research indicates that infants can also predict action goals of familiar simple actions performed by non-human agents (e.g., object-directed grasping by a mechanical claw) when these agents display agency cues, such as self-propelled movement, equifinality of goal approach, or production of a salient action effect. This paper provides a review on relevant findings and theoretical models, and proposes that the impacts of action experience and of agency cues can be explained from an action-event perspective. In particular, infants' goal-predictive gaze-shifts are seen as resulting from an interplay between bottom-up processing of perceptual information and top-down influences exerted by event schemata that store information about previously executed or observed actions.
Jóvenes ante el ciberodio
(2021)
Adolescentes de todo el mundo están cada vez más expuestos al ciberodio. Se necesita más conocimiento para comprender cómo los y las adolescentes afrontan estas experiencias. El presente estudio investigó la relación entre la mediación parental
en el uso de Internet y las estrategias de afrontamiento entre adolescentes centradas en el problema en una hipotética victimización en ciberodio, al tiempo que se consideró el apoyo familiar como moderador de estas relaciones. La muestra estuvo formada por 5.960 adolescentes de entre 12 y 18 años que completaron autoinformes (M=14,94; DE=1,61; mujeres: 50,7%) de Chipre, Alemania, Grecia, India, España, Corea del Sur y Tailandia. Se estimó un modelo de ecuaciones estructurales para investigar la relación entre mediación parental, apoyo social y afrontamiento. Se halló una relación positiva entre la mediación parental instructiva y el uso de estrategias de afrontamiento centradas en el problema y una relación negativa entre la mediación parental restrictiva y la capacidad de los adolescentes para afrontar de forma adecuada el ciberodio. Además, el apoyo familiar moderó estas relaciones, incrementando la relación entre mediación instructiva y afrontamiento y disminuyendo la relación entre mediación restrictiva y afrontamiento de ciberodio. Los hallazgos enfatizan la necesidad de proporcionar información a los padres y ponen de manifiesto la importancia de que las familias fomenten la habilidad de los adolescentes para afrontar de manera adecuada el ciberodio.
Aging in speech production is a multidimensional process. Biological, cognitive, social, and communicative factors can change over time, stay relatively stable, or may even compensate for each other. In this longitudinal work, we focus on stability and change at the laryngeal and supralaryngeal levels in the discourse particle euh produced by 10 older French-speaking females at two times, 10 years apart. Recognizing the multiple discourse roles of euh, we divided out occurrences according to utterance position. We quantified the frequency of euh, and evaluated acoustic changes in formants, fundamental frequency, and voice quality across time and utterance position. Results showed that euh frequency was stable with age. The only acoustic measure that revealed an age effect was harmonics-to-noise ratio, showing less noise at older ages. Other measures mostly varied with utterance position, sometimes in interaction with age. Some voice quality changes could reflect laryngeal adjustments that provide for airflow conservation utterance-finally. The data suggest that aging effects may be evident in some prosodic positions (e.g., utterance-final position), but not others (utterance-initial position). Thus, it is essential to consider the interactions among these factors in future work and not assume that vocal aging is evident throughout the signal.
