Abstract. This study aims to localize the brain regions involved in the apprehension of Korean laryngeal contrasts and to investigate whether the Internal Model advanced by Callan et al. (2004) extends to first versus second language perception of these unique three-way laryngeal distinctions. The results show that there is a significant difference in activation between native and second-language speakers, consistent with the findings of Callan et al. Specific activities unique to younger native speakers of Korean relative to native speakers of English were seen in the cuneus (occipital lobe) and the right middle frontal gyrus (Brodmann Area [BA] 10), areas of the brain associated with pitch perception. The current findings uphold Silva's (2006) conclusion that the laryngeal contrasts of Korean are increasingly distinguished less by VOT differences than by their effect on pitch in the following vowel. A subsequent experiment was conducted to establish whether more traditional, older native speakers of Korean who still make clear VOT distinctions also activate both the cuneus and BA 10 in the same task. Preliminary results indicate that they do not, whereas speakers with overlapping VOT distinctions do show intersecting activations in these areas, thus corroborating Silva's claim of emergent pitch sensitivity in the Korean laryngeal system.

AbstractHumor can often carry an implicit negative message and thus be potentially dangerous to use. In addition, it is culturally and linguistically complex and sophisticated. Because of these things, it poses a challenge for L2 (second language) speakers and we might expect to see attempts at humor failing and causing offense in intercultural interaction. This paper reports on a study that examined humor in interaction between native and non-native speakers of English and found that humor did not seem to be a cause of conflict because of adjustments speakers made to their speech and their situated interpretations of meaning. In general, taboo topics and potentially dangerous forms of humor were avoided and humor was carefully contextualized. Native speakers reported being careful about the vocabulary they used in creating humor and both sides appeared to approach humor in intercultural communication prepared to accommodate the other and with an attitude of leniency.

Evidence shows that second language (L2) learning affects cognitive function. Here in this work, we compared brain activation in native speakers of Mandarin (L1) who speak Japanese (L2) between and within two groups (high and low L2 ability) to determine the effect of L2 ability in L1 and L2 speaking tasks, and to map brain regions involved in both tasks. The brain activation during task performance was determined using prefrontal cortex blood flow as a proxy, measured by functional near-infrared spectroscopy (fNIRS). People with low L2 ability showed much more brain activation when speaking L2 than when speaking L1. People with high L2 ability showed high-level brain activation when speaking either L2 or L1. Almost the same high-level brain activation was observed in both ability groups when speaking L2. The high level of activation in people with high L2 ability when speaking either L2 or L1 suggested strong inhibition of the non-spoken language. A wider area of brain activation in people with low compared with high L2 ability when speaking L2 is considered to be attributed to the cognitive load involved in code-switching L1 to L2 with strong inhibition of L1 and the cognitive load involved in using L2.

The meaning of a novel word can be acquired by extracting it from linguistic context. Here we simulated word learning of new words associated to concrete and abstract concepts in a variant of the human simulation paradigm that provided linguistic context information in order to characterize the brain systems involved. Native speakers of Spanish read pairs of sentences in order to derive the meaning of a new word that appeared in the terminal position of the sentences. fMRI revealed that learning the meaning associated to concrete and abstract new words was qualitatively different and recruited similar brain regions as the processing of real concrete and abstract words. In particular, learning of new concrete words selectively boosted the activation of the ventral anterior fusiform gyrus, a region driven by imageability, which has previously been implicated in the processing of concrete words.

<p>This article was intended to explore the frequency and order of communication strategies used by Iranian male and female EFL earners as well as English native speakers while facing communication breakdowns. Furthermore, it was aimed to investigate the difference between native speakers and non-native speakers of English in their use of communication strategies. In addition, it was probed whether gender had any effects on the use of these strategies among native and non-native speakers. To this end, the data were collected through the communication strategy questionnaire distributed among 30 male and female Iranian intermediate EFL learners and 15 English native speakers. The design of this study was a quantitative one in which the questionnaire and thus numerical data were applied. To analyze the data, Cronbach alpha and independent-samples t-tests were used. The results indicated that non-verbal and social affective strategies were the most frequent strategies used by non-native speakers and native speakers of English, respectively. Furthermore, there was no significant difference between male and female Iranian EFL learners, but a significant difference between male and female English native speakers were seen. It can be concluded that language proficiency can contribute to the type and frequency of communications strategies which are used non-native speakers; likewise, it can play a significant role in gender differences in language use.<em></em></p>

Objective To test if sugar sweetened beverages (SSBs) and sugar sweetened solids (SSSs) have differential effects on body weight and reward processing in the brain. Methods In a single blind randomized controlled pilot trial (RCT), twenty participants with BMI between 20 and 40 kg/m2 were randomized to consume a 20 fluid ounce soda (SSB, 248 kcal) or the equivalent in solid form (SSS; similar to thick gelatin or gummy candy) daily. At baseline and day 28, fasting body weight and fed-state BOLD fMRI of the brain were assessed. Differences in fMRI signals between views of low-fat (LF (<30%)) high sugar (HS (>30%)) food, and non-food images were calculated in brain regions implicated in energy homeostasis, taste, and reward. Results All participants in the SSB (6F 4M; 8 Caucasian; 36±14 y, 28.2±5.5 kg/m2; Mean±SD) and SSS (3F 7M; 6 Caucasian; 39±12; 26.3±4.4) groups completed the study. Weight change was 0.27±0.78 kg between SSB and SSS participants. Changes in the fMRI response to LF/HS foods in reward, homeostatic and taste regions tended to not be different between the groups over the four weeks. However, activation of the right substantia nigra increased following the SSB but decreased activation following the SSS in response to LF/HS foods over 28 days (-0.32±0.12). Ratings of wanting for LF/HS foods were correlated with activation in several brain regions, including the OFC. Conclusions Change in weight was modest between the groups in this study. Daily consumption of a SSB over 28 days led to mixed responses to LF/HS foods in areas of the brain associated with reward. Ratings of wanting are correlated with fMRI activation inside an MRI scanner.

ABSTRACTSecond language speakers often struggle to apply grammatical constraints such as subject–verb agreement. One hypothesis for this difficulty is that it results from problems suppressing syntactically unlicensed constituents in working memory. We investigated which properties of these constituents make them more likely to elicit errors: their grammatical distance to the subject head or their linear distance to the verb. We used double modifier constructions (e.g., the smell of the stables of the farmers), where the errors of native speakers are modulated by the linguistic relationships between the nouns in the subject phrase: second plural nouns, which are syntactically and semantically closer to the subject head, elicit more errors than third plural nouns, which are linearly closer to the verb (2nd-3rd-noun asymmetry). In order to dissociate between grammatical and linear distance, we compared embedded and coordinated modifiers, which were linearly identical but differed in grammatical distance. Using an attraction paradigm, we showed that German native speakers and proficient Russian speakers of German exhibited similar attraction rates and that their errors displayed a 2nd-3rd-noun asymmetry, which was more pronounced in embedded than in coordinated constructions. We suggest that both native and second language learners prioritize linguistic structure over linear distance in their agreement computations.

Due to similarities between human and porcine, pigs have been proposed as an excellent experimental animal for human medical research. Especially in paediatric brain research, piglets share similarities with human infants in the extent of peak brain growth at the time of birth and the growth pattern of brain. Thus, these findings have supported the wider use of pigs rather than rodents in neuroscience research. Previously, we reported the production of porcine model of Parkinson's disease (PD) by nuclear transfer using donor cell that had been stably infected with lentivirus containing the human α-synuclein gene. The purpose of this study was to determine the alternation of brain metabolism and dopaminergic neuron destruction using noninvasive method in a 2-yr-old PD model and a control pig. The positron emission tomography (PET) scan was done using Biograph TruePoint40 with a TrueV (Siemens, Munich, Germany). The [18F]N-(3-fluoropropyl)-2β-carbomethoxy-3β-(4-iodophenyl) nortropane (FP-CIT) was administrated via the ear vein. Static images of the brain for 15 min were acquired from 2 h after injection. The 18F-fluorodeoxy-D-glucose PET (18F-FDG PET) images of the brain were obtained for 15 min at 45 min post-injection. Computed tomography (CT) scan and magnetic resonance imaging (MRI) were performed at the same location of the brain. In both MRI and CT images, there was no difference in brain regions between PD model and control pigs. However, administration of [18F]FP-CIT was markedly decreased in the bilateral putamen of the PD model pig compared with the control pigs. Moreover, [18F]FP-CIT administration was asymmetrical in the PD model pig but it was symmetrical in control pigs. Regional brain metabolism was also assessed and there was no significant difference in cortical metabolism of PD model and control pigs. We demonstrated that PET imaging could provide a foundation for translational Parkinson neuroimaging in transgenic pigs. In the present study, a 2-yr-old PD model pig showed dopaminergic neuron destruction in brain regions. Therefore, PD model pig expressing human α-synuclein gene would be an efficient model for human PD patients. This study was supported by Korea IPET (#311011–05–5-SB010), Research Institute for Veterinary Science, TS Corporation and the BK21 plus program.

Abstract The study of learners' pragmatic and discourse knowledge, also known as "interlanguage pragmatics", is now an important preoccupation of second-language acquisition (SLA) research. Spurred by this growing interest in interlanguage pragmatics and with a view to contributing to this field of research I conducted a study of requests in English produced by English as a second language (ESL) university students in their daily interaction mainly with lecturers. I collected the data for this study by means of observation and by recording "golden episodes of requesting behaviour in students' spontaneous speech. For comparative purposes, I elicited additional data by means of a discourse-completion task (DCT). One finding is that the students' knowledge of contextual use of requesting strategies in English is inadequate because their requests are of (very) limited range and inappropriate in context. The in-appropriacy of the requests was confirmed by native speakers' judgments. One explanation of the inadequacy of the students' pragmatic knowledge is the lack of exposure to the whole gamut of requesting devices. Another may have a strategic dimension. Also important is the explanation of transfer from the first language/s (Ll/s) : learners may be simply carrying over into English structures translated from their L1. From a pedagogical point of view, it is suggested that discourse and pragmatic knowledge be systematically taught to avoid miscommunication and negative reactions from native and competent non-native speakers of English. The suggestion of teaching pragmatic knowledge seems to be supported by the finding about one subject who, after exposure to a variety of requesting expressions, seemed to modify the pattern of her requests.

More and more evidence suggests that dopamine receptor D3 gene (DRD3) plays an important role in the clinical manifestations and the treatment of Parkinson’s disease (PD). DRD3 Ser9Gly polymorphism is the most frequently studied variant point. Our aim was to investigate the potential effect of DRD3 Ser9Gly polymorphism on modulating resting-state brain function and associative clinical manifestations in PD patients. We consecutively recruited 61 idiopathic PD patients and 47 healthy controls (HC) who were evaluated by clinical scales, genotyped for variant Ser9Gly in DRD3, and underwent resting-state functional magnetic resonance imaging. Based on DRD3 Ser9Gly polymorphism, PD patients and HCs were divided into four subgroups. Then, two-way analysis of covariance (ANCOVA) was applied to investigate main effects and interactions of PD and DRD3 Ser9Gly polymorphism on the brain function via amplitude of low-frequency fluctuations (ALFF) approach. The association between DRD3 Ser9Gly-modulated significantly different brain regions, and clinical manifestations were detected by Spearman’s correlations. PD patients exhibited decreased ALFF values in the right inferior occipital gyrus, lingual gyrus, and fusiform gyrus. A significant difference in the interaction of “groups × genotypes” was observed in the right medial frontal gyrus. The ALFF value of the cluster showing significant interactions was positively correlated with HAMD-17 scores (r=0.489, p=0.011) and anhedonia scores (r=0.512, p=0.008) in PD patients with the Ser/Gly or Gly/Gly genotypes. Therefore, D3 gene Ser9Gly polymorphism might be associated with the severity of depression characterized by anhedonia in PD patients.
