Previous research has shown that high phonotactic frequencies
facilitate the production of regularly inflected verbs in English-learning
children with specific language impairment (SLI) but not with typical
development (TD). We asked whether this finding can be replicated
for German, a language with a much more complex inflectional
verb paradigm than English. Using an elicitation task, the production
of inflected nonce verb forms (3 rd person singular with -t suffix)
with either high- or low-frequency subsyllables was tested in
sixteen German-learning children with SLI (ages 4;1–5 ;1), sixteen
TD-children matched for chronological age (CA) and fourteen TD-
children matched for verbal age (VA) (ages 3;0–3 ;11). The findings
revealed that children with SLI, but not CA- or VA-children, showed
differential performance between the two types of verbs, producing
more inflectional errors when the verb forms resulted in low-frequency
subsyllables than when they resulted in high-frequency subsyllables,
replicating the results from English-learning children.
In Germany, active bat rabies surveillance was conducted between 1993 and 2012. A total of 4546 oropharyngeal swab samples from 18 bat species were screened for the presence of EBLV-1- , EBLV-2- and BBLV-specific RNA. Overall, 0 center dot 15% of oropharyngeal swab samples tested EBLV-1 positive, with the majority originating from Eptesicus serotinus. Interestingly, out of seven RT-PCR-positive oropharyngeal swabs subjected to virus isolation, viable virus was isolated from a single serotine bat (E. serotinus). Additionally, about 1226 blood samples were tested serologically, and varying virus neutralizing antibody titres were found in at least eight different bat species. The detection of viral RNA and seroconversion in repeatedly sampled serotine bats indicates long-term circulation of the virus in a particular bat colony. The limitations of random-based active bat rabies surveillance over passive bat rabies surveillance and its possible application of targeted approaches for future research activities on bat lyssavirus dynamics and maintenance are discussed.
This study investigates whether number dissimilarities on subject and object DPs facilitate the comprehension of subject-and object-extracted centre-embedded relative clauses in children with Grammatical Specific Language Impairment (G-SLI). We compared the performance of a group of English-speaking children with G-SLI (mean age: 12; 11) with that of two groups of younger typically developing (TD) children, matched on grammar and receptive vocabulary, respectively. All groups were more accurate on subject-extracted relative clauses than object-extracted ones and, crucially, they all showed greater accuracy for sentences with dissimilar number features (i.e., one singular, one plural) on the head noun and the embedded DP. These findings are interpreted in the light of current psycholinguistic models of sentence comprehension in TD children and provide further insight into the linguistic nature of G-SLI.
Two experiments tested how faithfully German children aged 4; 5 to 5; 6 reproduce ditransitive sentences that are unmarked or marked with respect to word order and focus (Exp1) or definiteness (Exp2). Adopting an optimality theory (OT) approach, it is assumed that in the German adult grammar word order is ranked lower than focus and definiteness. Faithfulness of children's reproductions decreased as markedness of inputs increased; unmarked structures were reproduced most faithfully and unfaithful outputs had most often an unmarked form. Consistent with the OT proposal, children were more tolerant against inputs marked for word order than for focus; in conflict with the proposal, children were less tolerant against inputs marked for word order than for definiteness. Our results suggest that the linearization of objects in German double object constructions is affected by focus and definiteness, but that prosodic principles may have an impact on the position of a focused constituent.
Regular and irregular inflection in children's production has been examined in many previous studies. Yet, little is known about the processes involved in children's recognition of inflected words. To gain insight into how children process inflected words, the current study examines regular -t and irregular -n participles of German using the cross-modal priming technique testing 108 monolingual German-speaking children in two age groups (group I, mean age: 8;4, group II, mean age: 9;9) and a control group of.. adults. Although both age groups of children had the same full priming effect as adults for -t forms, only children of age group II showed an adult-like (partial) priming effect for -n participles. We argue that children (within the age range tested) employ the same mechanisms for regular inflection as adults but that the lexical retrieval processes required for irregular forms become more efficient when children get older.
Object and action naming in Russian- and German- speaking monolingual and bilingual children*
(2014)
The present study investigates the influence of word category on naming performance in two populations: bilingual and monolingual children. The question is whether and, if so, to what extent monolingual and bilingual children differ with respect to noun and verb naming and whether a noun bias exists in the lexical abilities of bilingual children. Picture naming of objects and actions by Russian-German bilingual children (aged 4-7 years) was compared to age-matched monolingual children. The results clearly demonstrate a naming deficit of bilingual children in comparison to monolingual children that increases with age. Noun learning is more fragile in bilingual contexts than is verb learning. In bilingual language acquisition, nouns do not predominate over verbs as much as is seen in monolingual German and Russian children. The results are discussed with respect to semantic-conceptual aspects and language-specific features of nouns and verbs, and the impact of input on the acquisition of these word categories.
Ultraschall Berlin

Masked priming research with late (non-native) bilinguals has reported facilitation effects following morphologically derived prime words (scanner - scan). However, unlike for native speakers, there are suggestions that purely orthographic prime-target overlap (scandal - scan) also produces priming in non-native visual word recognition. Our study directly compares orthographically related and derived prime-target pairs. While native readers showed morphological but not formal overlap priming, the two prime types yielded the same magnitudes of facilitation for non-natives. We argue that early word recognition processes in a non-native language are more influenced by surface-form properties than in one's native language.
This paper examines phonological phrasing in the Kwa language Akan. Regressive [+ATR] vowel harmony between words (RVH) serves as a hitherto unreported diagnostic of phonological phrasing. In this paper I discuss VP-internal and NP-internal structures, as well as SVO(O) and serial verb constructions. RVH is a general process in Akan grammar, although it is blocked in certain contexts. The analysis of phonological phrasing relies on universal syntax-phonology mapping constraints whereby lexically headed syntactic phrases are mapped onto phonological phrases. Blocking contexts call for a domain-sensitive analysis of RVH assuming recursive prosodic structure which makes reference to maximal and non-maximal phonological phrases. It is proposed (i) that phonological phrase structure is isomorphic to syntactic structure in Akan, and (ii) that the process of RVH is blocked at the edge of a maximal phonological phrase; this is formulated in terms of a domain-sensitive CrispEdge constraint.
Extract: Topics in psycholinguistics and the neurocognition of language rarely attract the attention of journalists or the general public. One topic that has done so, however, is the potential benefits of bilingualism for general cognitive functioning and development, and as a precaution against cognitive decline in old age. Sensational claims have been made in the public domain, mostly by journalists and politicians. Recently (September 4, 2014) The Guardian reported that “learning a foreign language can increase the size of your brain”, and Michael Gove, the UK's previous Education Secretary, noted in an interview with The Guardian (September 30, 2011) that “learning languages makes you smarter”. The present issue of BLC addresses these topics by providing a state-of-the-art overview of theoretical and experimental research on the role of bilingualism for cognition in children and adults.
Although morphosyntax has been identified as a major source of difficulty for adult (nonnative) language learners, most previous studies have examined a limited set of largely affix-based phenomena. Little is known about word-based morphosyntax in late bilinguals and of how morphosyntax is represented and processed in a nonnative speaker's lexicon. To address these questions, we report results from two behavioral experiments investigating stem variants of strong verbs in German (which encode features such as tense, person, and number) in groups of advanced adult learners as well as native speakers of German. Although the late bilinguals were highly proficient in German, the results of a lexical priming experiment revealed clear native-nonnative differences. We argue that lexical representation and processing relies less on morphosyntactic information in a nonnative than in a native language.

Background: Continuous treatment is an important indicator of medication adherence in dementia. However, long-term studies in larger clinical settings are lacking, and little is known about moderating effects of patient and service characteristics.
Methods: Data from 12,910 outpatients with dementia (mean age 79.2 years; SD = 7.6 years) treated between January 2003 and December 2013 in Germany were included. Continuous treatment was analysed using Kaplan-Meier curves and log-rank tests. In addition, multivariate Cox regression models were fitted with continuous treatment as dependent variable and the predictors antidementia agent, age, gender, medical comorbidities, physician specialty, and health insurance status.
Results: After one year of follow-up, nearly 60% of patients continued drug treatment. Donezepil (HR: 0.88; 95% CI: 0.82-0.95) and memantine (HR: 0.85; 0.79-0.91) patients were less likely to be discontinued treatment as compared to rivastigmine users. Patients were less likely to be discontinued if they were treated by specialist physicians as compared to general practitioners (HR: 0.44; 0.41-0.48). Younger male patients and patients who had private health insurance had a lower discontinuation risk. Regarding comorbidity, patients were more likely to be continuously treated with the index substance if a diagnosis of heart failure or hypertension had been diagnosed at baseline.
Conclusions: Our results imply that besides type of antidementia agent, involvement of a specialist in the complex process of prescribing antidementia drugs can provide meaningful benefits to patients, in terms of more disease-specific and continuous treatment.
The semantics of focus particles like only requires a set of alternatives (Rooth, 1992). In two experiments, we investigated the impact of such particles on the retrieval of alternatives that are mentioned in the prior context or unmentioned. The first experiment used a probe recognition task and showed that focus particles interfere with the recognition of mentioned alternatives and the rejection of unmentioned alternatives relative to a condition without a particle. A second lexical decision experiment demonstrated priming effects for mentioned and unmentioned alternatives (compared with an unrelated condition) while focus particles caused additional interference effects. Overall, our results indicate that focus particles trigger an active search for alternatives and lead to a competition between mentioned alternatives, unmentioned alternatives, and the focused element.
Rhythm perception is assumed to be guided by a domain-general auditory principle, the Iambic/Trochaic Law, stating that sounds varying in intensity are grouped as strong-weak, and sounds varying in duration are grouped as weak-strong. Recently, Bhatara et al. (2013) showed that rhythmic grouping is influenced by native language experience, French listeners having weaker grouping preferences than German listeners. This study explores whether L2 knowledge and musical experience also affect rhythmic grouping. In a grouping task, French late learners of German listened to sequences of coarticulated syllables varying in either intensity or duration. Data on their language and musical experience were obtained by a questionnaire. Mixed-effect model comparisons showed influences of musical experience as well as L2 input quality and quantity on grouping preferences. These results imply that adult French listeners' sensitivity to rhythm can be enhanced through L2 and musical experience.
Changes in free symptom attributions in hypochondriasis after cognitive therapy and exposure therapy
(2016)
Background: Cognitive-behavioural therapy can change dysfunctional symptom attributions in patients with hypochondriasis. Past research has used forced-choice answer formats, such as questionnaires, to assess these misattributions; however, with this approach, idiosyncratic attributions cannot be assessed. Free associations are an important complement to existing approaches that assess symptom attributions. Aims: With this study, we contribute to the current literature by using an open-response instrument to investigate changes in freely associated attributions after exposure therapy (ET) and cognitive therapy (CT) compared with a wait list (WL). Method: The current study is a re-examination of a formerly published randomized controlled trial (Weck, Neng, Richtberg, Jakob and Stangier, 2015) that investigated the effectiveness of CT and ET. Seventy-three patients with hypochondriasis were randomly assigned to CT, ET or a WL, and completed a 12-week treatment (or waiting period). Before and after the treatment or waiting period, patients completed an Attribution task in which they had to spontaneously attribute nine common bodily sensations to possible causes in an open-response format. Results: Compared with the WL, both CT and ET reduced the frequency of somatic attributions regarding severe diseases (CT: Hedges's g = 1.12; ET: Hedges's g = 1.03) and increased the frequency of normalizing attributions (CT: Hedges's g = 1.17; ET: Hedges's g = 1.24). Only CT changed the attributions regarding moderate diseases (Hedges's g = 0.69). Changes in somatic attributions regarding mild diseases and psychological attributions were not observed. Conclusions: Both CT and ET are effective for treating freely associated misattributions in patients with hypochondriasis. This study supplements research that used a forced-choice assessment.
Much research on language control in bilinguals has relied on the interpretation of the costs of switching between two languages. Of the two types of costs that are linked to language control, switching costs are assumed to be transient in nature and modulated by trial-specific manipulations (e.g., by preparation time), while mixing costs are supposed to be more stable and less affected by trial-specific manipulations. The present study investigated the effect of preparation time on switching and mixing costs, revealing that both types of costs can be influenced by trial-specific manipulations.
The Gradient Symbolic Computation (GSC) model presented in the keynote article (Goldrick, Putnam & Schwarz) constitutes a significant theoretical development, not only as a model of bilingual code-mixing, but also as a general framework that brings together symbolic grammars and graded representations. The authors are to be commended for successfully integrating a theory of grammatical knowledge with the voluminous research on lexical co-activation in bilinguals. It is, however, unfortunate that a certain conception of bilingualism was inherited from this latter research tradition, one in which the contrast between native and non-native language takes a back seat.
Processes involved in late bilinguals' production of morphologically complex words were studied using an event-related brain potentials (ERP) paradigm in which EEGs were recorded during participants' silent productions of English past- and present-tense forms. Twenty-three advanced second language speakers of English (first language [L1] German) were compared to a control group of 19 L1 English speakers from an earlier study. We found a frontocentral negativity for regular relative to irregular past-tense forms (e.g., asked vs. held) during (silent) production, and no difference for the present-tense condition (e.g., asks vs. holds), replicating the ERP effect obtained for the L1 group. This ERP effect suggests that combinatorial processing is involved in producing regular past-tense forms, in both late bilinguals and L1 speakers. We also suggest that this paradigm is a useful tool for future studies of online language production.
