In connected speech, many words are produced with a pronunciation that differs from the canonical form. How the speech recognition system deals with this variation is a fundamental issue in the language processing literature. The present study examines the roles of variant type, variant frequency, and context in the processing of French words with a canonical (schwa variant, e.g. semaine “week”) and a non-canonical pronunciation (no-schwa variant, s’maine). It asks whether the processing of canonical pronunciations is faster than the processing of non-canonical ones. Results of three lexical decision experiments reveal that more frequent variants are recognised more quickly, and that there is no advantage for canonical forms once variant frequency is accounted for. Two of these experiments further failed to find evidence that the context in which the words are presented modulate the effect of variant type. These findings are discussed in the light of spoken word recognition models.
This study investigated Dutch-speaking four- to five-year-olds’ use of word order and prosody in distinguishing focus types (broad focus, narrow focus, and contrastive narrow focus) via an interactive answer-reconstruction game. We have found an overall preference for the unmarked word order SVO and no evidence for the use of OVS to distinguish focus types. But the children used pitch and duration in the subject-nouns to distinguish focus types in SVO sentences. These findings show that Dutch-speaking four- to five-year-olds differ from their German- and Finnish-speaking peers, who show evidence of varying choice of word order to mark specific focus types, and use prosody to distinguish focus types in subject and object nouns in both SVO and OVS sentences. These comparisons suggest that typological differences in the relative importance between word order and prosody can lead to differences in children’s use of word order and prosody in unmarked and marked word orders. A more equal role of word order and prosody in the ambient language can stimulate more extensive use of prosody in the marked word order, whereas a more limited role of word order can restrict the use of prosody in the unmarked word order.
This study investigated whether Mandarin speakers interpret prosodic information as focus markers in a sentence-picture verification task. Previous production studies have shown that both Mandarin-speaking adults and Mandarin-speaking children mark focus by prosodic information (Ouyang and Kaiser in Lang Cogn Neurosc 30(1-2):57-72, 2014; Yang and Chen in Prosodic focus marking in Chinese four-and eight-year-olds, 2014). However, while prosodic focus marking did not seem to affect sentence comprehension in adults Mandarin-speaking children showed enhanced sentence comprehension when the sentence focus was marked by prosodic information in a previous study (Chen in Appl Psycholinguist 19(4):553-582, 1998). The present study revisited this difference between Mandarin speaking adults and children by applying a newly designed task that tested the use of prosodic information to identify the sentence focus. No evidence was obtained that Mandarin-speaking children (as young as 3years of age) adhered more strongly to prosodic information than adults but that word order was the strongest cue for their focus interpretation. Our findings support the view that children attune to the specific means of information structure marking in their ambient language at an early age.
Interactional linguistics
(2018)
The first textbook dedicated to interactional linguistics, focusing on linguistic analyses of conversational phenomena, this introduction provides an overview of the theory and methodology of interactional linguistics. Reviewing recent findings on linguistic practices used in turn construction and turn taking, repair, action formation, ascription, and sequence and topic organization, the book examines the way that linguistic units of varying size - sentences, clauses, phrases, clause combinations, and particles - are mobilized for the implementation of specific actions in talk-in-interaction. A final chapter discusses the implications of an interactional perspective for our understanding of language as well as its variation, diversity, and universality. Supplementary online chapters explore additional topics such as the linguistic organization of preference, stance, footing, and storytelling, as well as the use of prosody and phonetics, and further practices with language. Featuring summary boxes and transcripts from recordings of everyday conversation, this is an essential resource for advanced undergraduate and postgraduate courses on language in social interaction.
That’s not quite it
(2018)
We present a novel empirical study on German directly comparing the exhaustivity inference in es-clefts to exhaustivity inferences in definite pseudoclefts, exclusives, and plain intonational focus constructions. We employ mouse-driven verification/falsification tasks in an incremental information-retrieval paradigm across two experiments in order to assess the strength of exhaustivity in the four sentence types. The results are compatible with a parallel analysis of clefts and definite pseudoclefts, in line with previous claims in the literature (Percus 1997, Buring & Kriz 2013). In striking contrast with such proposals, in which the exhaustivity inference is conventionally coded in the cleft-structure in terms of maximality/homogeneity, our study found that the exhaustivity inference is not systematic or robust in es-clefts nor in definite pseudoclefts: Whereas some speakers treat both constructions as exhaustive, others treat both constructions as non-exhaustive. In order to account for this unexpected finding, we argue that the exhaustivity inference in both clefts and definite pseudoclefts-specifically those with the compound definite derjenige - is pragmatically derived from the anaphoric existence presupposition that is common to both constructions.
Encountering a cataphoric pronoun triggers a search for a suitable referent. Previous research indicates that this search is constrained by binding Condition C, which prohibits coreference between a cataphoric pronoun and a referential expression within its c-command domain. We report the results from a series of eye-movement monitoring and questionnaire experiments investigating cataphoric pronoun resolution in German. Given earlier findings suggesting that the application of structure-sensitive constraints on reference resolution may be delayed in non-native language processing, we tested both native and proficient non-native speakers of German. Our results show that cataphoric pronouns trigger an active search in both native and non-native comprehenders. Whilst both participant groups demonstrated awareness of Condition C in an offline task, we found Condition C effects to be restricted to later processing measures during online reading. This indicates that during natural reading, Condition C applies as a relatively late filter on potential coreference assignments.
Over the last decades mechanisms of recognition of morphologically complex words have been extensively examined in order to determine whether all word forms are stored and retrieved from the mental lexicon as wholes or whether they are decomposed into their morphological constituents such as stems and affixes. Most of the research in this domain focusses on English. Several factors have been argued to affect morphological processing including, for instance, morphological structure of a word (e.g., existence of allomorphic stem alternations) and its linguistic nature (e.g., whether it is a derived word or an inflected word form). It is not clear, however, whether processing accounts based on experimental evidence from English would hold for other languages. Furthermore, there is evidence that processing mechanisms may differ across various populations including children, adult native speakers and language learners. Recent studies claim that processing mechanisms could also differ between older and younger adults (Clahsen & Reifegerste, 2017; Reifegerste, Meyer, & Zwitserlood, 2017).
The present thesis examined how properties of the morphological structure, types of linguistic operations involved (i.e., the linguistic contrast between inflection and derivation) and characteristics of the particular population such as older adults (e.g., potential effects of ageing as a result of the cognitive decline or greater experience and exposure of older adults) affect initial, supposedly automatic stages of morphological processing in Russian and German. To this end, a series of masked priming experiments was conducted.
In experiments on Russian, the processing of derived -ost’ nouns (e.g., glupost’ ‘stupidity’) and of inflected forms with and without allomorphic stem alternations in 1P.Sg.Pr. (e.g., igraju – igrat’ ‘to play’ vs. košu – kosit’ ‘to mow’) was examined. The first experiment on German examined and directly compared processing of derived -ung nouns (e.g., Gründung ‘foundation’) and inflected -t past participles (e.g., gegründet ‘founded’), whereas the second one investigated the processing of regular and irregular plural forms (-s forms such as Autos ‘cars’ and -er forms such as Kinder ‘children’, respectively).
The experiments on both languages have shown robust and comparable facilitation effects for derived words and regularly inflected forms without stem changes (-t participles in German, forms of -aj verbs in Russian). Observed morphological priming effects could be clearly distinguished from purely semantic or orthographic relatedness between words. At the same time, we found a contrast between forms with and without allomorphic stem alternations in Russian and regular and irregular forms in German, with significantly more priming for unmarked stems (relative to alternated ones) and significantly more priming for regular (compared) word forms. These findings indicate the relevance of morphological properties of a word for initial stages of processing, contrary to claims made in the literature holding that priming effects are determined by surface form and meaning overlap only. Instead, our findings are more consistent with approaches positing a contrast between combinatorial, rule-based and lexically-stored forms (Clahsen, Sonnenstuhl, & Blevins, 2003).
The doctoral dissertation also addressed the role of ageing and age-related cognitive changes on morphological processing. The results obtained on this research issue are twofold. On the one hand, the data demonstrate effects of ageing on general measures of language performance, i.e., overall longer reaction times and/or higher accuracy rates in older than younger individuals. These findings replicate results from previous studies, which have been linked to the general slowing of processing speed at older age and to the larger vocabularies of older adults. One the other hand, we found that more specific aspects of language processing appear to be largely intact in older adults as revealed by largely similar morphological priming effects for older and younger adults. These latter results indicate that initial stages of morphological processing investigated here by means of the masked priming paradigm persist in older age. One caveat should, however, be noted. Achieving the same performance as a younger individual in a behavioral task may not necessarily mean that the same neural processes are involved. Older people may have to recruit a wider brain network than younger individuals, for example. To address this and related possibilities, future studies should examine older people’s neural representations and mechanisms involved in morphological processing.
According to the Shallow Structure Hypothesis (SSH), second language (L2) speakers, unlike native speakers, build shallow syntactic representations during sentence processing. In order to test the SSH, this study investigated the processing of a syntactic movement in both native speakers of English and proficient late L2 speakers of English using pupillometry to measure processing cost. Of particular interest were constructions where movement resulted in an intermediate gap between clauses. Pupil diameter was recorded during auditory presentation of complex syntactic constructions. Two factors were manipulated: syntactic movement (such that some conditions contained movement while others did not), as well as syntactic movement type (either causing an intermediate gap or not). Grammaticality judgments revealed no differences between the two groups, suggesting both were capable of comprehending these constructions. Pupil change slope measurements revealed a potential sensitivity to intermediate gaps for only native speakers, however, both native and late L2 speakers showed similar facilitation during processing of the second gap site. Acoustic analysis revealed potential acoustic cues that may have facilitated the processing of these constructions. This suggests that, contrary to the predictions of the SSH, late L2 speakers are capable of constructing rich syntactic representations during the processing of intermediate gap constructions in spoken language.
A close call
(2018)
The present study investigated how lexical selection is influenced by the number of semantically related representations (semantic neighbourhood density) and their similarity (semantic distance) to the target in a speeded picture-naming task. Semantic neighbourhood density and similarity as continuous variables were used to assess lexical selection for which competitive and noncompetitive mechanisms have been proposed. Previous studies found mixed effects of semantic neighbourhood variables, leaving this issue unresolved. Here, we demonstrate interference of semantic neighbourhood similarity with less accurate naming responses and a higher likelihood of producing semantic errors and omissions over accurate responses for words with semantically more similar (closer) neighbours. No main effect of semantic neighbourhood density and no interaction between semantic neighbourhood density and similarity was found. We assessed further whether semantic neighbourhood density can affect naming performance if semantic neighbours exceed a certain degree of semantic similarity. Semantic similarity between the target and each neighbour was used to split semantic neighbourhood density into two different density variables: The number of semantically close neighbours versus distant neighbours. The results showed a significant effect of close, but not of distant, semantic neighbourhood density: Naming pictures of targets with more close semantic neighbours led to longer naming latencies, less accurate responses, and a higher likelihood for the production of semantic errors and omissions over accurate responses. The results show that word inherent semantic attributes such as semantic neighbourhood similarity and the number of coactivated close semantic neighbours modulate lexical selection supporting theories of competitive lexical processing.
