Are you reading what I am reading? The impact of contrasting alphabetic scripts on reading English

This study examines the impact of the crosslinguistic similarity of translation equivalents on word recognition by Russian-English bilinguals, who are fluent in languages with two different but partially overlapping writing systems. Current models for bilingual word recognition, like BIA+, hold that all words that are similar to the input letter string are activated and considered for selection, irrespective of the language to which they belong (Dijkstra and Van Heuven, 2002). These activation models are consistent with empirical data for bilinguals with totally different scripts, like Japanese and English (Miwa et al., 2014). Little is known about the bilingual processing of Russian and English, but studies indicate that the partially distinct character of the Russian and English scripts does not prevent co-activation (Jouravlev and Jared, 2014; Marian and Spivey, 2003; Kaushanskaya and Marian, 2007)

The effect of language-specific characteristics on English and Japanese speakers' ability to recall number information

The current paper presents two experiments investigating the effect of presence versus absence of compulsory number marking in a native language on a speaker’s ability to recall number information from photos. In Experiment 1, monolingual English and Japanese adults were shown a sequence of 110 photos after which they were asked questions about the photos. We found that the English participants showed a significantly higher accuracy rate for questions testing recall for number information when the correct answer was ‘2’ (instead of ‘1’) than Japanese participants. In experiment 2, English and Japanese adults engaged in the same task as in Experiment 1 with an addition that explored reasons for the results found in Experiment 1. The results of Experiment 2 were in line with the results of Experiment 1, but also suggested that the results could not be attributed to differences in guessing patterns between the two groups or the type of linguistic constructions used in the test situations. The current study suggests that native language affects speakers’ ability to recall number information from scenes and thus provides evidence for the Whorfian hypothesis

PySDM v1 : particle-based cloud modeling package for warm-rain microphysics and aqueous chemistry

PySDM is an open-source Python package for simulating the dynamics of particles undergoing condensational and collisional growth, interacting with a fluid flow and subject to chemical composition changes. It is intended to serve as a building block for process-level as well as computational-fluid-dynamics simulation systems involving representation of a continuous phase (air) and a dispersed phase (aerosol), with PySDM being responsible for representation of the dispersed phase. The PySDM package core is a Pythonic high-performance implementation of the Super-Droplet Method (SDM) Monte-Carlo algorithm for representing collisional growth, hence the name. PySDM has two alternative parallel number-crunching backends available: multi-threaded CPU backend based on Numba and GPU-resident backend built on top of ThrustRTC. The usage examples are built on top of four simple atmospheric cloud modelling frameworks: box, adiabatic parcel, single-column and 2D prescribed flow kinematic models. In addition, the package ships with tutorial code depicting how PySDM can be used from Julia and Matlab

Investigation of the freeze-out configuration in the ^{197}Au + ^{197}Au reaction at 23 A MeV

According to the model predictions, observation of toroidal objects is expected in collisions of heavy ion at low incident energies. Comparison between experimental data and model predictions which may indicate the formation of flat/toroidal nuclear systems is shown

Light fragments production and isospin dependences in Sn+Ni and Sn+Al central collisions at 25MeV/A and 35MeV/A from reverse/isospin experiments

This paper presents the physical analysis results for the following reactions: 124Sn+64Ni, 124Sn+27Al, 124Sn+58Ni at 35MeV/A and 25MeV/A. The main goal of this studies was to find observables sensitive to isospin effects and to present the similarities/differences between the systems characterised by various charge asymmetry factor, defined as I = (NZ)=A. Theoretical simulations based on the Quantum Molecular Dynamics (QMD) model have been performed in order to compare them with the results of the analysis of experimental data. The first phase of the reaction was carried out with the code CHIMERA [1]. The sequential decay of hot fragments was simulated by the code COOLER [2]. The conclusions are as follows: there are observables sensitive to the isospin of the system, such as the Light Charged Particles (LCP) emission and their sensitivity is demonstrated more prominently in the analysis of central collisions at 35MeV/A. The theoretical calculations do not reproduce these relations well

The effects of proficiency on sub-lexical processing in bilingual visual word recognition

Systematic psycholinguistic research has considered the nature of the coexistence of two (or more) languages in the cognitive system of a fluent bilingual speaker. There is increasing consensus that when a bilingual is presented with a visual stimulus in one language, both of their languages are initially activated (non-selective access; e.g. Dijkstra & van Heuven 2002a). However, more recent research shows that certain factors may constrain (or eliminate) the activation of a task-irrelevant language (Duyck, van Assche, Drieghe, & Hartsuiker 2007; Elston-Güttler, Gunter, & Kotz 2005). The objective of the research in this thesis was to investigate how cross-linguistic activation is modulated by specific characteristics of a bilingual’s languages. This exploration was mainly limited to an under-investigated area, namely early sub-lexical word processing. The first of two studies focussed on word processing in the presence or absence of critical sub-lexical information. Specifically, I investigated whether onset capitals – a prominent marker indicating nouns in German – acted as a language-specific cue, and the extent to which this cue constrains competitive, lexical interaction between the bilingual’s languages (e.g. Hose-hose, the first being a German word meaning ‘trousers’ in English). This study also considered the extent to which the use of such information is affected by priming for a specific language from a preceding context sentence. The second study arose from a claim that readers employ distinct sub-lexical reading strategies, depending on the extent of spelling-to-sound (in)consistency in their language (e.g. Ziegler, Perry, Jacobs, & Braun 2001). Employing a bilingual population whose two languages were clearly distinguished in terms of such consistency, I explored the reading strategy used by bilingual participants reading in each language. A key issue is competitive activation between sub-lexical orthographic and phonological representations across languages. Each study was conducted with two groups of bilingual speakers, English-German and German-English. Individuals varied in their L2 proficiency, allowing a test of whether sub-lexical processing changed as a consequence of increasing proficiency. The main results from study one demonstrate that bilingual speakers are dependent upon sub-lexical, language-specific information. However, this is influenced by L2 proficiency, with a stronger effect for lower proficiency bilinguals. In addition, lower proficiency bilinguals were more dependent on sub-lexical cues when primed by a sentence in L2. In contrast, bilingual speakers performing in their L1 used these cues largely under very specific circumstances, i.e. when they did not know an item. The central finding of study two is that competition between sub-lexical orthographic and phonological representations across languages largely depends on the amount of spelling-to-sound (in)consistency in the bilinguals’ more dominant language. This is reflected in (1) slower identification of orthographically similar cognates which map onto different phonological representations across two languages, and (2) slower identification of cognates which do not share the same orthographic form across languages but have a common phonological representation. In addition, increasing L2 proficiency is reflected in attenuation of certain effects as processing becomes more automatic, and the development of a common reading strategy accommodating reading in either language. A major contribution of the research conducted is what findings from both studies reveal about how the bilingual lexicon develops as proficiency increases. Furthermore, the findings contribute to our understanding of the organisation of the bilingual mental lexicon and the processes of word identification, and impose constraints on possible cognitive architectures

Discourse-pragmatic markers, fillers and filled pauses: Pragmatic, cognitive, multimodal and sociolinguistic perspectives

Despite being the object of considerable research effort over several decades, the status and function of discourse-pragmatic markers (DPMs), fillers and filled pause (FPs) continue to be at the forefront of an expanding field of scholarly debate.The current Special Issue brings together researchers on DPMs and FPs working across different research traditions with a common interest in pragmatics. These include sociolinguists and psycholinguists, those interested in multimodal approaches and more applied aspects such as first and second language acquisition and language contact, alongside those of a more theoretical bent, investigating cognitive aspects of the items recruited as filler words, their socio-interactional functions, and how form-function mappings come about

Awake craniotomy with English and British Sign Language mapping in a patient with a left temporal glioblastoma reveals discordant speech-sign language maps

The aim of this case study was to describe differences in English and British Sign Language (BSL) communication caused by a left temporal tumour resulting in discordant presentation of symptoms, intraoperative stimulation mapping during awake craniotomy and post-operative language abilities. We report the first case of a hearing child of deaf adults, who acquired BSL with English as a second language. The patient presented with English word finding difficulty, phonemic paraphasias, and reading and writing challenges, with BSL preserved. Intraoperatively, object naming and semantic fluency tasks were performed in English and BSL, revealing differential language maps for each modality. Post-operative assessment confirmed mild dysphasia for English with BSL preserved. These findings suggest that in hearing people who acquire a signed language as a first language, topographical organisation may differ to that of a second, spoken, language

The effect of a bilingual learning mode on the establishment of lexical semantic representations in the L2

Deliberate vocabulary learning is common in the L2, however, questions remain about most efficient and effective forms of this learning approach. Bilingual models of L2 word learning and processing can be used to make predictions about outcomes of learning new vocabulary from bilingual (L2-L1) flashcards, and these predictions can be tested experimentally. In the present study, 41 late adult German-English bilinguals learned 48 English pseudowords using bilingual flashcards. Quality of component lexical representations established for the studied items was probed using form priming and semantic priming. The results show that, although all participants were able to establish robust orthographic representations of the studied items, only bilinguals with large L2 vocabularies established high-quality lexical semantic representations. With neither the Revised Hierarchical Model (RHM) nor the Sense Model able to fully account for these findings, an alternative explanation based on a distributed semantic features view of word learning is proposed. Learning implications of the findings are discussed. © Cambridge University Press 2013
