Background: The Association of the Scientific Medical Societies in Germany (AWMF) clinical practice guideline on cochlear implant (CI) treatment, which was updated in 2020, defined the entire process of CI care for the first time. In the present study, the feasibility and results of very early rehabilitation were examined.
Materials and methods: The intervention group (IG) comprised 54 patients in whom rehabilitation was initiated within 14 (maximally 28) days after implantation. Patients with a significantly longer waiting time were included in the control group (CG, n = 21). In addition to the start and duration of rehabilitation, the speech intelligibility achieved with CI was recorded at different timepoints within a 12-month period. In addition, questionnaires were used to assess the effort of fitting the CI processor and the patients’ satisfaction with the outcome as well as the timing of the start of rehabilitation.
Results: Median waiting time between implantation and start of rehabilitation was 14 days in the IG and 106 days in the CG; 92.6% of IG patients were able to start rehabilitation within 14 days. The effect of rehabilitation in the IG was 35 and in the CG 25 percentage points (Freiburg monosyllabic test). After 6 and 12 months of CI use, both groups showed comparable results in the test condition in quiet (IG/CG 6 months: 70%/70%; 12 months: 70%/60%, Freiburg monosyllabic test) and in noise (IG/CG 6 months: −1.1 dB SNR/–0.85 dB SNR; 12 months: −0.65 dB SNR/+0.3 dB SNR, Oldenburg sentence test). Hearing quality assessment scores collected by SSQ (Speech, Spatial and Qualities of Hearing Scale) questionnaire showed better scores in the IG at 6 months, which converged to CG scores at 12 months. The IG was significantly more satisfied with the timing of the start of rehab than the CG. All other data obtained from questionnaires showed no differences between the two groups.
Conclusion: A very early start of inpatient rehabilitation after cochlear implantation was successfully implemented. The rehabilitation was completed within 7 weeks of CI surgery. Comparison of speech recognition test results before and after rehabilitation showed a significant improvement. A clear rehabilitation effect can therefore be demonstrated. Inclusion of CI rehabilitation in the German catalog of follow-up treatments is thus scientifically justified and therefore strongly recommended.
The comprehension and production of single words involve a variety of processing stages. Which stages need to be accessed differs depending on whether objects (pictures in an experimental environment) or words are supposed to be named. Naming tasks are often employed in psycholinguistic studies in order to provide an insight into the function of mental processes during word production. Differences in naming latencies and naming accuracy between words suggest that the retrieval of some lexical items is easier or more difficult in contrast to others. The relative ease of word retrieval has been found to be strongly influenced by properties of these words, such as familiarity and written or spoken frequency.
Exploring which variables affect naming speed and accuracy will allow gaining more information about the storage and processing of words in general. If a variable has a discernable effect on a specific experimental task, the localization of this effect is of interest for psycholinguistic research. This is because finding the locus of the effect can help specify models of speech production with respect to what processes occur at which stage of lexical retrieval. Additionally, identifying which variables influence language processing is inevitable in order to control for these variables when necessary. Otherwise variance in naming latencies could not be explained by the variable that was to be tested because other, uncontrolled variables could have altered the results.
Embedded implicatures and experimental constraints : a reply to Geurts & Pouscoulous and Chemla
(2010)
Experimental evidence on embedded implicatures by Chemla (2009b) and Geurts & Pouscoulous (2009a) has fewer theoretical consequences than assumed: On the one hand, the evidence successfully argues against obligatory local implicature computation, which has however already been discredited. On the other hand, the data are fully consistent with optional local implicature computation.
It is well known that English children between the age of 4 and 6 display a so-called Delay of Principle B Effect (DPBE) in that they allow pronouns to refer to a local c-commanding antecedent. Their guessing pattern with pronouns contrasts with their adult-like interpretation of reflexives. The DPBE has been explained as resulting from a lack of pragmatic knowledge or insufficient cognitive resources. However, such extra-grammatical accounts cannot explain why the DPBE only shows up in particular languages and in particular syntactic environments. Moreover, such accounts fail to explain why the DPBE only emerges in comprehension and not in production. This paper hypothesizes that the presence or absence of the DPBE can be explained from the properties of the grammar. Fischer's (2004) optimality-theoretic analysis of binding, explaining cross-linguistic variation, and Hendriks and Spenader's (2005/6) optimality-theoretic account of the acquisition of pronouns and reflexives are combined into a single model. This model yields testable predictions with respect to the presence or absence of the DPBE in particular languages, in particular syntactic environments, and in comprehension and/or production.
This paper investigates the production and comprehension of intrasentential anaphoric pronominal reference in Russian. In particular, it examines the elicited imitation and comprehension of three anaphoric pronouns in subject position – personal 3rd singular masculine, demonstrative and zero – in one hundred and eighty monolingual Russian-speaking children and twenty adults. The three types of pronouns were designed to have an antecedent in the preceding sentence containing a verb and two arguments. These antecedents differ in their syntactical role and animacy. The sentence position, agentivity and topicality remained constant. The sentences with (in)animate subjects and objects constituted the following four 'conditions': two sentences with a subject and an object being either animate or inanimate and two sentences with a subject and an object exhibiting a diverse (in)animacy. Regarding the resolution of the anaphoric pronouns the similarity principle (or feature-concord rule) and its possible violations were tested. This principle suggests that an anaphoric pronoun is most likely resolved to the antecedent with a maximum of similar characteristics or features and it primarily governs the assignment of an antecedent to anaphoric pronouns in subject position in the absence of the violating conditions. Results show the influence of this rule on the anaphora resolution process increasing with age, on the one hand, and the development of the impact of animacy, syntactic role and the type of anaphoric pronouns that violate the feature-concord rule, on the other.
The paper presents results from a combined production and comprehension study addressing some of the factors which guide the establishment of intersentential pronominal reference in child and adult Bulgarian. We investigate the time course and different stages in the acquisition of null, personal and demonstrative pro-nouns and their specific anaphoric functions. We target possible age-induced changes in the salience hierarchy of referent features such as animacy and grammatical role. Following the general consent in the field of anaphora research, we assume a division of labour between different pronominal forms with respect to the salience of their referents. Based on the data of Bulgarian preschool children we investigate the validity of this form-function relation, its language-specific shape and its developmentally induced variation. The results reveal an initial prominence of animate referents which later on develops into preference for animate subjects. Although the investigated 3 to 5 year old Bulgarian children do not stick to the adult anaphora resolution strategy, they comply with the principle of the reversed mapping within the range of tested pronouns and react according to their salience criteria which promote animate subjects as the most prominent co-reference candidates.
In anaphora resolution theory, it has been assumed that anaphora resolution is based on a reversed mapping of antecedent salience and anaphora complexity: minimal complex anaphora refer to maximal salient antecedents. In order to ex-amine whether and by which developmental steps German children gain command of this mapping maxim we conducted an experiment on production and comprehension of intersentential pronouns including the three pronoun types zero, personal, and demonstrative pronoun. With respect to antecedent salience, the experiment varied syntactic role (subject/object) and in/animacy. Six age groups of children (age range from 2;0 to 6;0) and an adult control group has been tested. The hypothesis arising from the mapping maxim is that zero pronoun correlates with more salient antecedents than personal and demonstrative pronoun, the latter correlating with the least salient antecedents. The results are: In production, children first establish the opposition of zero pronoun with animate antecedents vs. demonstrative pronoun with inanimate antecedents. In a next step, syntactic role comes into play and a more complex system opposing the three presented pronoun types is established. In comprehension, however, the effect of pronoun type re-mains weak and antecedent features remain a strong factor in reference choice. However, also adults employ pronoun type and antecedent features. The oldest children and the adults show variation in personal pronoun resolution according to the animacy pattern of the potential antecedents. In case of identical animacy features, the subject is the preferred candidate; in case of distinct animacy features, there is a tendency to choose the object antecedent.
The 48th volume of the ZAS Papers in Linguistics presents selected papers from the conference on Intersentential pronominal reference in child and adult language held at the ZAS in December, 2006. The conference, organized by the project Acquisition and disambiguation of intersentential pronominal reference, brought together leading researchers dealing with anaphora resolution in diverse theoretical approaches and the acquisition perspective on pronominal reference taken by the ZAS project.
This paper presents psycholinguistic evidence on the factors governing the resolution of German personal pronouns. To determine the relative influence of linear order versus grammatical function of potential antecedents, two interpretation-preference tasks were designed. Their specific aim was to disentangle salience factors conflated in previous research on pronoun interpretation, such as linear or-der, first mention and topicalization. Experiment 1 tested pronoun resolution to non-sentence-initial position (scrambling) and Experiment 2 tested pronoun resolution to sentence-initial position (topicalization). The results across different verb types and across different syntactic contexts in Experiments 1 and 2 show that grammatical function, yet neither linear order, first mention nor topicalization predicts pronoun resolution in German.
In this paper, focusing on the relevance-theoretic view of cognition, I discuss the idea that what is communicated through an utterance is not merely an explicature upon which implicature(s) are recovered, but rather a propositional complex that contains both explicit and implicit information. More specifically, I propose that this information is constructed on the fly as the interpreter processes every lexical item in its turn while parsing the utterance in real time, in this way creating a string of ad hoc concepts. While hearing an utterance and incrementally constructing a context, the propositional complex communicated by an utterance is pragmatically narrowed and simultaneously pragmatically broadened in order to incorporate only the set of optimally relevant propositions with respect to a specific point in the interpretation. The narrowing of propositions from the initial context at each stage allows relevant propositions to be carried on to the new level, while their broadening adds to the communicated propositional complex new propositions that are linked to the lexical item that is processed at every step of the interpretation process.
