It is well established that statistical properties of sequences are implicitly learned, and that these statistical properties correlate with changes in kinematic and speech behavior. For speech, this means that more predictable items are phonetically shorter. Accordingly, we hypothesized for glossolalia that if practitioners have learned a serial pattern in glossolalia in the same manner as in natural languages, its statistical properties should correlate with its phonetic characteristics.

Formal theoretical analyses of NAI informed the design of a task in which American English-speaking participants unfamiliar with this structure were exposed to NAI sentences in either semantically ambiguous or unambiguous contexts. Participants rapidly adapted to the interpretive properties of NAI, selecting responses similar to what would be expected of a native speaker after only limited exposure to semantically ambiguous input. On a separate ratings task, participants displayed knowledge of syntactic restrictions on NAI subject type, despite having no previous exposure.

My goal is to answer whether bilingual speakers can adjust their L1 coarticulatory settings in their L2 and to observe whether their L2 accentedness plays a role in ultimate attainment. Ten native speakers of Spanish (L1Sp) who were highly proficient L2 English speakers participated in Spanish and English read-aloud tasks. A control group of 16 L1 English speakers undertook the English experiment. Aerodynamic data were collected using pressure transducers. Each participant produced tokens with nasalized vowels in CVN# words and oral vowels in CV(CV) words. Four linguistically trained judges (two per target language) evaluated a set of pseudo-randomized sentences produced by the participants containing words with nasalized vowels and rated the speech on a 1 (heavily accented) to 9 (native-like) Likert-type scale. Measurements for onset and degree of overall nasality were obtained. Results indicate the L1Sp group can accommodate gestural timing strategies cross-linguistically as they exhibit an earlier nasality onset and increment nasality proportion in L2 English in a native-like manner. In addition, a positive correlation between greater vowel nasality degree and native-like accentedness in the L2 was found, suggesting L2 timing settings might be specified in higher spoken proficiency levels.</p>","PeriodicalId":51255,"journal":{"name":"Language and Speech","volume":" ","pages":"238309231215355"},"PeriodicalIF":1.8,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139059054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of the double-binding stemming from the explicit-implicit incongruity, irony is assumed to be cognitively taxing when communicated in the native language (NL), and even more so in the foreign language (FL). Prior studies investigating irony comprehension in the FL indicated that irony may be processed with similar speed and accuracy in the foreign and the native language, and that irony comprehension efficiency in the former might be lower. Building on these findings, this study investigates if the tasks participants perform when reading irony in their FL affect the efficiency of irony comprehension. We invited 150 advanced Polish users of English to take part in one of two tasks. Participants were asked to read 3- to 5-sentence-long-scenarios, ending in literal (Literal Praise, Literal Criticism) or ironic comments (Ironic Praise, Ironic Criticism) and to either (1) make true/false judgments (T/F task; <i>N</i> = 83), or to (2) judge the emotional value in emotive decision task (EDT; <i>N</i> = 67). A full spectrum of verbal irony employed to communicate ironic praise and criticism, and their literal equivalents: literal praise and literal criticism, was tested. A three-way mixed ANOVA with 2× Valence (Praise, Criticism), 2× Mode (Literal, Ironic) as within-subject repeated-measures, and 2× Task (True/False, Emotive Decision) as a between-subject independent measure, revealed that efficiency of irony comprehension was differently modified by the two tasks.
