Validity of Two Language Versions of the Auckland Individualism and Collectivism Scale with Filipino-English Bilinguals

The Auckland Individualism and Collectivism Scale (AICS) was translated into Filipino; and the factorial structure of the Filipino and English versions were validated with two samples of Filipino-English bilinguals. Most of the fit indexes in the confirmatory factor analysis indicated that the data from the Filipino translation and the original English version both fit the hypothesized internal structure of the scale. The results provide further support for the structural aspects of the AICS’ construct validity; however, some minor issues were noted at the level of individual items and subscales.     

Activation of number facts in bilinguals

Two experiments examined the effect of the presentation format of numbers—digits versus word format in the first and in the second languages of bilinguals—on mental arithmetic. Speed of number-fact retrieval and the presence of interference produced by numbers that were either numerically close to or associatively related to the correct answers of stored arithmetic problems (e.g., 2+5 and 7×8) were compared across formats. The verification of true problems was increasingly slower and less accurate from the digit condition to the second-language condition. Interference was produced by both types of incorrect answers in the digit and first-language conditions, whereas in the second-language condition, it was constrained to answers that were numerically close to correct answers. Together, the results suggest that the retrieval of arithmetic facts and the automatic spreading of activation within the network of numerical facts are not only language-sensitive, but format-sensitive in general.     

Language Format and Analogical Transfer among Bilingual Problem Solvers in the Philippines

Is analogical problem solving of bilinguals affected by the language in which the problem is given? Three experiments study whether the language used for the problem affects analogical transfer between word problems among Filipino-English bilinguals. Subjects were given a set of study problems all of which were either in Filipino or English. They were then given a set of analogous transfer-test problems either in Filipino or in English. Experiment 1 showed a language-compatibility effect; transfer was better when the language of the study and transfer-test problems were the same. Experiments 2 to 3 studied the locus of the effect. The data suggest that language compatibility facilitates the retrieval of relevant, superficially similar problem information but does not affect the process of applying the same problem information to the new problem. The results are discussed in terms of their implications to problem-solving behaviour of bilinguals and to the education of bilingual students.     

Bimodal bilinguals co-activate both languages during spoken comprehension

Bilinguals have been shown to activate their two languages in parallel, and this process can often be attributed to overlap in input between the two languages. The present study examines whether two languages that do not overlap in input structure, and that have distinct phonological systems, such as American Sign Language (ASL) and English, are also activated in parallel. Hearing ASL-English bimodal bilinguals' and English monolinguals' eye-movements were recorded during a visual world paradigm, in which participants were instructed, in English, to select objects from a display. In critical trials, the target item appeared with a competing item that overlapped with the target in ASL phonology. Bimodal bilinguals looked more at competing item than at phonologically unrelated items and looked more at competing items relative to monolinguals, indicating activation of the sign-language during spoken English comprehension. The findings suggest that language co-activation is not modality specific, and provide insight into the mechanisms that may underlie cross-modal language co-activation in bimodal bilinguals, including the role that top-down and lateral connections between levels of processing may play in language comprehension.     

Proficiency in a second language influences the processing of number words

We evaluated whether proficiency in a second language (L2) influenced the processing of numerical information. In Experiment 1, two groups of German/English bilinguals, one less proficient in English (L2) and the other more proficient in L2, performed two-digit number comparison tasks while the unit–decade compatibility was evaluated. All participants presented compatibility effect with Arabic digits regardless of their L2 proficiency. However, when bilinguals with less proficiency in L2 performed verbal number comparison tasks they showed regular compatibility effect in German and reverse compatibility effect in English, whereas more proficient bilinguals did not show compatibility effects in either German or English. In Experiment 2, the same pattern of results was obtained with highly proficient bilinguals after controlling their working memory span. These results indicate that L2 proficiency influences the processing of two-digit number words.     

Bilinguals Show Weaker Lexical Access During Spoken Sentence Comprehension

When bilinguals process written language, they show delays in accessing lexical items relative to monolinguals. The present study investigated whether this effect extended to spoken language comprehension, examining the processing of sentences with either low or high semantic constraint in both first and second languages. English-German bilinguals, German-English bilinguals and English monolinguals listened for target words in spoken English sentences while their eye-movements were recorded. Bilinguals’ eye-movements reflected weaker lexical access relative to monolinguals; furthermore, the effect of semantic constraint differed across first versus second language processing. Specifically, English-native bilinguals showed fewer overall looks to target items, regardless of sentence constraint; German-native bilinguals activated target items more slowly and maintained target activation over a longer period of time in the low-constraint condition compared with monolinguals. No eye movements to cross-linguistic competitors were observed, suggesting that these lexical access disadvantages were present during bilingual spoken sentence comprehension even in the absence of overt interlingual competition.     

Morphological priming survives a language switch

In a long-lag morphological priming experiment, Dutch (L1)-English (L2) bilinguals were asked to name pictures and read aloud words. A design using non-switch blocks, consisting solely of Dutch stimuli, and switch-blocks, consisting of Dutch primes and targets with intervening English trials, was administered. Target picture naming was facilitated by morphologically related primes in both non-switch and switch blocks with equal magnitude. These results contrast some assumptions of sustained reactive inhibition models. However, models that do not assume bilinguals having to reactively suppress all activation of the non-target language can account for these data.     

A study of semantic and syntactic processing in monolinguals and fluent early bilinguals

The present study consists of two reaction-time experiments administered in English. These experiments were designed to compare semantic and syntactic processing in English monolinguals and fluent early French-English bilinguals. Results of both experiments revealed that the bilinguals did not function as the English monolinguals did. That is, their reaction times were slower and they made twice as many errors in response to certain sentences. These findings are especially important for two reasons: (1) The bilinguals were all highly fluent, and in most cases dominant, in English, and (2) the bilinguals exhibited systematic differences in two different linguistic components (the semantic and the syntactic). The results are viewed as evidence of the interdependence of the bilinguals' languages. Some note is made of individual patterns of response, and two interpretations of linguistic interdependence are provided.

Exploring the developmental changes in automatic two-digit number processing

Even when two-digit numbers are irrelevant to the task at hand, adults process them. Do children process numbers automatically, and if so, what kind of information is activated? In a novel dot-number Stroop task, children (Grades 1-5) and adults were shown two different two-digit numbers made up of dots. Participants were asked to select the number that contained the larger dots. If numbers are processed automatically, reaction time for dot size judgment should be affected by numerical characteristics. The results suggest that, like adults, children process two-digit numbers automatically. Based on the current findings, we propose a developmental trend for automatic two-digit number processing that goes from decomposed sequential (activation of decade digit followed by that of unit digit) to decomposed parallel processing (simultaneous activation of decade and unit digits).     

Language learning and control in monolinguals and bilinguals

Parallel language activation in bilinguals leads to competition between languages. Experience managing this interference may aid novel language learning by improving the ability to suppress competition from known languages. To investigate the effect of bilingualism on the ability to control native-language interference, monolinguals and bilinguals were taught an artificial language designed to elicit between-language competition. Partial activation of interlingual competitors was assessed with eye-tracking and mouse-tracking during a word recognition task in the novel language. Eye-tracking results showed that monolinguals looked at competitors more than bilinguals, and for a longer duration of time. Mouse-tracking results showed that monolinguals' mouse movements were attracted to native-language competitors, whereas bilinguals overcame competitor interference by increasing the activation of target items. Results suggest that bilinguals manage cross-linguistic interference more effectively than monolinguals. We conclude that language interference can affect lexical retrieval, but bilingualism may reduce this interference by facilitating access to a newly learned language.     

The activation of phonological representations by bilinguals while reading silently: evidence from interlingual homophones

These experiments investigated whether bilinguals activate phonological representations from both of their languages when reading silently in one. The critical stimuli were interlingual homophones (e.g., sank in English and cinq in French). French-English and English-French bilinguals completed an English lexical decision task. Decisions made by French-English bilinguals were significantly faster and more accurate for interlingual homophones than for matched English control words. In subsequent experiments, the homophone facilitation effect in the latency data disappeared when distractors were changed to pseudohomophones, when cognates and interlingual homographs were added to the experiment, and when the proportion of critical stimuli was decreased. However, the homophone effect in the error data remained. In contrast, English-French bilinguals revealed little evidence of an interlingual homophone effect. Several attempts were made to increase the saliency of the nontarget language, however these manipulations produced only a small effect in the error data. These results indicate that the activation of phonological representations can appear to be both language-specific and nonspecific depending on the proficiency of the bilinguals and whether they are reading in their weaker or stronger language.     

Do bilinguals have two personalities? A special case of cultural frame switching

Four studies examined and empirically documented Cultural Frame Switching (CFS; Hong, Chiu, & Kung, 1997) in the domain of personality. Specifically, we asked whether Spanish–English bilinguals show different personalities when using different languages? If so, are the two personalities consistent with cross-cultural differences in personality? To generate predictions about the specific cultural differences to expect, Study 1 documented personality differences between US and Mexican monolinguals. Studies 2–4 tested CFS in three samples of Spanish–English bilinguals, located in the US and Mexico. Findings replicated across all three studies, suggesting that language activates CFS for Extraversion, Agreeableness, and Conscientiousness. Further analyses suggested the findings were not due to anomalous items or translation effects. Results are discussed in terms of the interplay between culture and self.

Non-Selective Lexical Access in Late Arabic–English Bilinguals: Evidence from Gating

Previous research suggests that late bilinguals who speak typologically distant languages are the least likely to show evidence of non-selective lexical access processes. This study puts this claim to test by using the gating task to determine whether words beginning with speech sounds that are phonetically similar in Arabic and English (e.g., [b,d,m,n]) give rise to selective or non-selective lexical access processes in late Arabic–English bilinguals. The results show that an acoustic-phonetic input (e.g., [bæ]) that is consistent with words in Arabic (e.g., [bædrun] “moon”) and English (e.g., [bæd] “bad”) activates lexical representations in both languages of the bilingual. This non-selective activation holds equally well for mixed lists with words from both Arabic and English and blocked lists consisting only of Arabic or English words. These results suggest that non-selective lexical access processes are the default mechanism even in late bilinguals of typologically distant languages.     

Effect of language proficiency and executive control on verbal fluency performance in bilinguals

We use a time-course analysis to examine the roles of vocabulary size and executive control in bilinguals’ verbal fluency performance. Two groups of bilinguals and a group of monolingual adults were tested in English with verbal fluency subtests from the Delis–Kaplan Executive Function System. The two bilingual groups were equivalent in their self-rated English proficiency but differed in levels of receptive and expressive vocabulary. We hypothesized that the difference between the two bilingual groups in vocabulary and between the monolingual and bilingual groups in executive control would lead to differences in performance on the category and letter fluency tests and dissociate the roles of vocabulary knowledge and executive control in verbal production. Bilinguals and monolinguals performed equivalently in category fluency, but the high-vocabulary bilingual group outperformed both monolinguals and low-vocabulary bilinguals in letter fluency. An analysis of the retrieval time-course functions in letter fluency showed dissociable effects of resources available at the initiation of the trial, considered to reflect vocabulary size, and ability to monitor and retrieve new items using a novel phonemic-based word searching strategy, considered to reflect executive control. The difference in slope of the best-fitting curves reflected enhanced executive control for both bilingual groups compared to monolinguals, whereas the difference in the starting point of the logarithmic functions reflected higher levels of vocabulary for high-vocabulary bilinguals and monolinguals compared to low-vocabulary bilinguals. The results are discussed in terms of the contributions of linguistic resources and executive control to verbal performance.     

语言理解转换中非目标语言影响目标语言的时间进程

运用跨语言即时启动和延时启动范式,要求被试完成生物属性的语义判断任务,研究语言理解转换中非目标语言影响目标语言语义理解的时间进程。实验1非目标语言为英文,目标语言为中文,结果表明,无论是即时启动(t = -0.423, p = 0.676),还是延时启动(t = -0.82, p = 0.419),语义相关组与语义无关组都无显著差异。实验2非目标语言为中文,目标语言为英文,结果表明,在即时启动条件下,语义相关组显著快于语义无关组(t = -3.05, p = 0.006),但延时条件下语义相关组与语义无关组无显著差异(t = -0.63, p = 0.536)。综合两个实验结果表明,晚期熟练双语者在双语语言理解转换过程中语义的即时启动影响存在不对称性,语义相关的非目标语言中文对目标语言英文语义理解起促进作用;但是语义启动效应没有得到延时体现。     

The processing of two-digit numbers in bilinguals

We explored possible between-language influences when bilinguals processed two-digit numbers. Spanish/English bilinguals and German/English bilinguals performed a number comparison task with Arabic digits and verbal numbers in their first language (L1) and second language (L2) while the unit-decade compatibility was manipulated. The two bilingual groups showed regular compatibility effect with Arabic digits. In L1, Spanish/English bilinguals showed reverse compatibility effect, while German/English bilinguals showed regular compatibility effect. However, both groups of bilinguals presented reverse compatibility effect in English (L2), which suggested that the bilinguals' L1 did not determine the processing of number words in their L2. The results indicated that bilinguals processed two-digit number words selectively in their L1 and L2 and that they did not transcode L2 numbers into Arabic format.     

Language and modeling word problems in mathematics among bilinguals

The study was conducted to determine whether the language of math word problems would affect how Filipino-English bilingual problem solvers would model the structure of these word problems. Modeling the problem structure was studied using the problem-completion paradigm, which involves presenting problems without the question. The paradigm assumes that problem solvers can infer the appropriate question of a word problem if they correctly grasp its problem structure. Arithmetic word problems in Filipino and English were given to bilingual students, some of whom had Filipino as a first language and others who had English as a first language. The problem-completion data and solution data showed similar results. The language of the problem had no effect on problem-structure modeling. The results were discussed in relation to a more circumscribed view about the role of language in word problem solving among bilinguals. In particular, the results of the present study showed that linguistic factors do not affect the more mathematically abstract components of word problem solving, although they may affect the other components such as those related to reading comprehension and understanding.     

非熟练中-英双语者跨语言的错误记忆通道效应

采用DRM范式以112名非熟练中-英双语者为被试进行了跨语言的错误记忆通道效应实验。实验采用三因素混合设计,根据学习通道和测验通道的不同,把被试分为4组,用由汉语与英语单词组成的DRM词表进行学习和测验。结果发现,⑴在非熟练中-英双语被试中存在错误记忆的跨语言现象;⑵非熟练中-英双语者跨语言的错误记忆存在很强的语言特异性,表现为相同语言条件高于不同语言条件、汉语高于英语;⑶在学习与测验相同语言条件下运用校正的再认分数——敏感性指标Pr,进一步探讨错误记忆的通道效应,发现了跟西方不一致的结论：即无论汉语词表还是英语词表,非熟练中-英双语者在视觉通道上的错误记忆明显高于听觉通道
