This study contributes to a central debate within contemporary generative second language (L2) theorizing: the extent to which adult learners are (un)able to acquire new functional features that result in a L2 grammar that is mentally structured like the native target (see White, 2003). The adult acquisition of L2 nominal phi-features is explored, with focus on the syntactic and semantic reflexes in the related domain of adjective placement in two experimental groups: English-speaking intermediate (n = 21) and advanced (n = 24) learners of Spanish, as compared to a native-speaker control group (n = 15). Results show that, on some of the tasks, the intermediate L2 learners appear to have acquired the syntactic properties of the Spanish determiner phrase but, on other tasks, to show some delay with the semantic reflexes of prenominal and postnominal adjectives. Crucially, however, our data demonstrate full convergence by all advanced learners and thus provide evidence in contra the predictions of representational deficit accounts (e.g., Hawkins & Chan, 1997; Hawkins & Franceschina, 2004; Hawkins & Hattori, 2006).

Using the eye-movement monitoring technique in two reading comprehension experiments, we investigated the timing of constraints on wh-dependencies (so-called ‘island’ constraints) in native and nonnative sentence processing. Our results show that both native and nonnative speakers of English are sensitive to extraction islands during processing, suggesting that memory storage limitations affect native and nonnative comprehenders in essentially the same way. Furthermore, our results show that the timing of island effects in native compared to nonnative sentence comprehension is affected differently by the type of cue (semantic fit versus filled gaps) signalling whether dependency formation is possible at a potential gap site. Whereas English native speakers showed immediate sensitivity to filled gaps but not to lack of semantic fit, proficient German-speaking learners of L2 English showed the opposite sensitivity pattern. This indicates that initial wh-dependency formation in nonnative processing is based on semantic feature-matching rather than being structurally mediated as in native comprehension.

This study used ERP (event-related potentials) to examine both the role of the L1 and the role of individual differences in the processing of agreement violations. Theories of L2 acquisition differ with regard to whether or not native-like acquisition of L2 features is possible (Schwartz and Sprouse, 1994, 1996; Tsimpli and Mastropavlou, 2007), and the results of previous ERP studies are inconsistent when it comes to whether or not native-like processing is observed in response to L2 agreement violations (e.g., Sabourin, 2003; Tokowicz and MacWhinney, 2005). Furthermore, studies of learners in early stages of L2 acquisition have found variability in the emergence of native-like responses (e.g., McLaughlin et al., 2010; Tanner et al., 2009), but sources of variability have not been investigated. The current study examines responses to gender and number agreement violations in English-speaking learners of Spanish (n=24). Stimuli targeted agreement in three conditions: subject-verb agreement (el barco flota/*flotan), which is similar in Spanish and English; number agreement on adjectival predicates (la isla rocosa/*rocosas), a context in which agreement is not instantiated in English; and gender agreement on adjectival predicates (la isla rocosa/*rocoso), which is unique to Spanish. Grammaticality judgments and ERP responses were also tested for correlations with aptitude scores on the Modern Languages Aptitude Test (MLAT; Carroll and Sapon, 1959) and the Raven Advanced Progressive Matrices (Raven, 1965). Results are in line with theories that claim native-like processing is acquirable, since learners demonstrated similar ERP responses to a control group of native Spanish-speakers (n=8) with regard to all three agreement types. Additionally, the MLAT (but not the Raven) was significantly correlated with sensitivity to number violations, both in terms of grammaticality judgments and ERP amplitudes, indicating a role for verbal but not nonverbal aptitude in L2 processing.

This paper describes the methodology used to compile a corpus called MorphoQuantics that contains a comprehensive set of 17,943 complex word types extracted from the spoken component of the British National Corpus (BNC). The categorisation of these complex words was derived primarily from the classification of Prefixes, Suffixes and Combining Forms proposed by Stein (2007). The MorphoQuantics corpus has been made available on a website of the same name; it lists 554 word-initial and 281 word-final morphemes in English, their etymology and meaning, and records the type and token frequencies of all the associated complex words containing these morphemes from the spoken element of the BNC, together with their Part of Speech. The results show that, although the number of word-initial affixes is nearly double that of word-final affixes, the relative number of each observed in the BNC is very similar; however, word-final affixes are more productive in that, on average, the frequency with which they attach to different bases is three times that of word-initial affixes. Finally, this paper considers how linguists, psycholinguists and psychologists may use MorphoQuantics to support their empirical work in first and second language acquisition, and clinical and educational research.

The word zenzen is an adverb that is used frequently in daily conversational Japanese. From the Meiji period (1868-1912) until the early Showa period (1924-1989) the word was used together with both affirmative and negative words to form expressions. In the early Showa period the grammatical rules in education changed so that the only acceptable use was together with a negative word. From the 1990’s onward, the use together with an affirmative word has made a comeback especially among younger Japanese people. However even though the usage together with an affirmative word has made a comeback and was considered normal once in history, in today’s society it is still considered as slang and thus not recommended usage in formal situations. Foreign language learners however, tend not to learn a language only by textbooks but also by imitating the language of native Japanese speakers and Japanese popular culture. This may lead to a confusion regarding what words are acceptable to use in conversations. Therefore in this study, an online survey that examines the usage and attitudes regarding the word zenzen aimed at Japanese language learners at Swedish universities was conducted. The results of the survey showed that although a majority of the learners showed a good understanding of the usage, more than half of the learners displayed a feeling of confusion regarding the usage of the word. The gender comparison regarding the usage showed no major differences. Having lived in Japan, having Japanese friends whom you speak Japanese with regularly and length of Japanese study was associated with an increased understanding of the usage. Regular consumption of Japanese popular culture, however, was not associated with an increased understanding of the usage. A literature analysis was also conducted to examine the attitudes regarding the usage of zenzen in a variety of books with topics including business language and books aimed at Japanese language teachers. The results showed that zenzen used together with a negative word was considered as the norm while zenzen used together with an affirmative word was not recommended to be used in formal situations. When recommending proper usage of the word zenzen together with an affirmative word to foreign learners of Japanese, hijou-ni and totemo was seen as better alternatives to zenzen in a formal situation.

La ricerca, che ha per oggetto lo studio dell’apprendimento guidato dell’italiano come lingua seconda da parte di apprendenti lituani, si articola in quattro capitoli. I primi due costituiscono il quadro teorico della ricerca, dedicando il primo ai fondamenti teorici e ricerche empiriche in generale e il secondo alle ricerche sull’apprendimento dell’italiano come L2. Nel terzo capitolo viene presentata la metodologia della ricerca, mentre nel quarto capitolo vengono presentati i risultati, concentrandosi in particolare sull’ortografia, sulla morfologia del nome, sulla categoria del verbo e sugli aspetti sintattici.In base ai risultati conseguiti, che in parte confermano i percorsi acquisizionali rilevati in contesto di apprendimento spontaneo, vengono all’ultimo suggerite alcune proposte applicative.

Abstract Within the field of neuroscientific research on second language learning, considerable attention has been devoted to functional and recently also structural changes related to second language acquisition. The present literature review summarizes studies that investigated structural changes related to bilingualism. Furthermore, as recent evidence has suggested that native-like exposure to a second language (i.e., a naturalistic learning setting or immersion) considerably impacts second language learning, all findings are reflected with respect to the learning environment. Aggregating the existing evidence, we conclude that structural changes in left inferior frontal and inferior parietal regions have been observed in studies on cortical gray matter changes, while the anterior parts of the corpus callosum have been repeatedly found to reflect bilingualism in studies on white matter (WM) connectivity. Regarding the learning environment, no cortical alterations can be attributed specifically to naturalistic or classroom learning. With regard to WM changes, one might tentatively propose that changes in IFOF and SLF are possibly more prominently observed in studies investigating bilinguals with a naturalistic learning experience. However, future studies are needed to replicate and strengthen the existing evidence and to directly test the impact of naturalistic exposure on structural brain plasticity.
