The present study investigated the impact of language use on self-perceived personality and personality as perceived by others in the bilingual Chinese-English context. We used a repeated-measures design and collected data at three time points from written measures and experimental settings, to examine whether bilinguals (n = 76) exhibit different patterns of personality characteristics, each associated with one of the two languages and interlocutor ethnicity, and to delineate such discrepancies using behavioral observations in addition to self-reports. By analyzing ratings by targets, interlocutors, and observers, our findings confirmed perception effects, language effects, and ethnicity effects on various personality dimensions, such as extraversion, openness to experience and assertiveness. We suggest that using a second language accesses the perceived cultural norms in which it is applied, especially the prototypic personality profiles in that culture, thus activating behavioral expressions of personality that are appropriate in the corresponding linguistic-social context. / Chen , Xiaohua Sylvia. / "July 2007." / Adviser: Michael Harris Bond. / Source: Dissertation Abstracts International, Volume: 69-01, Section: B, page: 0728. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2007. / Includes bibliographical references (p. 60-70). / Electronic reproduction.

Continuous control of two languages during speech production may result in a ‘bilingual advantage’, where highly proficient bilinguals outperform monolinguals on nonverbal cognitive tasks. Greater linguistic distance between two bilingual languages is expected to influence this relationship, where bilinguals who engage with similar languages develop enhanced inhibitory control. To address this issue, this study examined reaction times and correct response rates on the attentional network task (ANT) and the Simon Task, where three different attentional networks (alerting, orienting and executive control) were examined. Two bilingual groups (English-German and English-Chinese) and one monolingual group (English) completed these attentional tasks as well as a Language Experience and Proficiency Questionnaire (LEAP-Q). Results did not provide unequivocal support for the ‘bilingual advantage’ hypothesis, which was only demonstrated by superior performance of bilinguals on the congruent and incongruent trials of the Simon Task. The Simon effect did not differ significantly between bilingual and monolingual participants, and no significant differences were revealed by performance on the ANT. The findings of this study also suggest that the effects of linguistic distance on cognitive functioning may not be quantitative in nature and should be investigated using neuroimaging techniques.

Previous bilingual studies showed reduced hemispheric asymmetry in visual tasks such as face perception in bilinguals compared with monolinguals, which suggested that hemispheric asymmetry in visual tasks could be modulated by experience in reading one or two languages. Here I examined whether differences in hemispheric asymmetry in visual tasks can also be observed in bilinguals who have different language backgrounds. I compared the behavior of three language groups: (1) English monolinguals, who acquire only one alphabetic language, (2) European-English bilinguals, who know two alphabetic languages, and (3) Chinese-English bilinguals, who master an alphabetic language and a logographic language; in three tachistoscopic tasks: (1) English word sequential matching task, (2) Intact-altered face judgment task, and (3) face sequential matching task. The results showed that European-English bilinguals had a stronger right visual field (RVF)/ left hemispheric (LH) advantage in the English word sequential matching task than English monolinguals and Chinese-English bilinguals, suggesting that different language learning experiences can influence how visual words are processed in the brain. However, the results showed no group difference between the left visual field (LVF)/ right hemisphere (RH) advantage in the intact-altered face judgment task and the face sequential matching task. These results suggested a modulation of language experience on visual word processing but not on face processing. In addition, I showed that the hemispheric asymmetry in visual word processing could be accounted for by a computational model that implements a theory of hemispheric asymmetry in perception (i.e. the Double Filtering by Frequency theory, Ivry & Robertson, 1998); the modeling data suggested that this lateralization difference in visual word processing may be due to both the difference in participants’ vocabulary size and the difference in word-to-sound mapping between alphabetic and logographic languages. / published_or_final_version / Psychology / Master / Master of Philosophy

Both of these theoretical positions - the linguistics and the behavioristic - are introduced here as parallel structures within which a study of language can proceed. As this study is developed, each strand is evident to some extent, with a synthesis of the two evolving in a psycholinguistic model which characterizes actual language use. This model, with the addiction of a bilingual dimension, is then discussed in light of schizophrenic language deviations.

Becoming literate carries with it the ability to develop and access higher-order thinking skills that are the building blocks for cognitive academic language proficiency, as well as the means that define educational opportunities (Bialystok, 2007). South Africa has 11 official languages and a multilingual education policy but South African schools are able to determine their language of instruction policy of monolingualism or multilingualism (Heugh, 2010). This raises the question of whether monolingualism or bilingualism influences children’s successful acquisition of reading. It is important to investigate the effect this has on reading processes and skills of monolingual and bilingual children because this issue has received limited research attention while it contributes to our greater understanding of how children’s cognitive capacities for literacy attainment are either constrained or promoted through broader social factors operating in a child’s literacy-learning environment (Bialystok, 2007; Vygotsky, 1978). Cognitive processing and reading skills were assessed in monolingual and bilingual children at a public school in an urban area of Johannesburg. An English-speaking monolingual group with English as the language of instruction (N = 100) was compared with a Zulu-English bilingual group with Zulu as first language (L1) speaking proficiency and English as second language (L2) literacy experience (N = 100) on measures of reading, phonological awareness, vocabulary skills, and working memory. Performance in cognitive processing and reading skills of these two groups was compared to an Afrikaans-English bilingual group (N = 100) with dual medium instruction. Tests of language proficiency confirmed that the Afrikaans-English bilinguals were balanced bilinguals and that the Zulu-English bilinguals were partial bilinguals. Aim and method: The purpose of this study was to expand knowledge in the field of second language reading acquisition and language of instruction by examining the impact of language related factors on the cognitive development and literacy competence of monolingual and bilingual children in the South African context. The central tenet of the bio-ecological approach to language, cognitive and reading assessment is that language acquisition is inseparable from the context in which it is learned (Armour-Thomas & Go-Paul-McNicol, 1997). Drawing from this approach, the present research project investigated the effects of the level of orthographic transparency on reading development in the transparent L1 and opaque L2 of biliterate Afrikaans-English bilinguals learning to read in a dual medium school setting. The effects of oral vs. written language proficiency in the L1 on the acquisition of L2 English reading was also investigated by examining whether reading processes and skills transferred from one language to another and the direction or nature of this transfer in partial and balanced bilinguals. Finally, whether a balanced bilingualism and biliteracy Cognitive processing skills and literacy development in monolingual and bilingual children in South Africa vi experience had beneficial effects on cognitive tasks demanding high levels of working memory capacity, was investigated. Results: Reading in Afrikaans – the more transparent orthography – reached a higher competency level than reading in the less transparent English. Dual medium learners and L1 English monolingual learners acquired reading skills in their home language(s) at a higher level than L2 English with L1 Zulu speaking proficiency learners did. Dual medium learners outperformed both monolingual learners and L2 English with L1 Zulu speaking proficiency learners on tests of phonological awareness, working memory, and reading comprehension. They also reached similar competency levels in tests of vocabulary knowledge than monolingual English (L1) learners. These differences translated into different relationships and strengths for reading attainment in monolingual and bilingual children. These findings provide support for a language-based and context-dependent bio-ecological model of reading attainment for South African children. Conclusions: Bilingual children who are exposed to dual medium reading instruction programmes that value bilingualism philosophically and support it pedagogically create optimal conditions for high levels of cognitive development and academic achievement, both in the first and in the L2. Absence of mother tongue instruction and English-only instruction result in a reading achievement gap between emergent Zulu-English bilinguals and English monolinguals. This effect is not observed in the biliterate Afrikaans-English bilinguals; instead, these children performed better than the English monolinguals on many English tasks and working tasks requiring high levels of executive control and analysis of linguistic knowledge, despite English being their L2 while learning to concurrently read in Afrikaans and English. Arguments for and (misguided) arguments against dual medium education are examined to identify the consequences of translating this model of education into effective schooling practices, given the socio-political contexts in which educational reforms take place at local schools and in communities (Heugh, 2002). More broadly, good early childhood education includes a rich language learning environment with skilled, responsive teachers who facilitate children’s literacy learning by providing intentional exposure to and support for vocabulary and concept development. Classroom settings that provide extensive opportunities to build children’s reading competences are beneficial for young dual language learners no less than for children acquiring literacy skills in a one-language environment (Cummins, 2000; Heugh, 2002). / GR2017
