It has been widely hypothesized that while doing arithmetic, individuals use two distinct routes for phonological output. A direct route is used for exact arithmetic which is language dependent, while an indirect route is used during arithmetic approximation and thought to be language independent. The arithmetic double route has been incorporated on the triple- code model that consists of visual arabic code for identifying strings of digits, magnitude code for knowledge in numeral quantities,...
Show moreIt has been widely hypothesized that while doing arithmetic, individuals use two distinct routes for phonological output. A direct route is used for exact arithmetic which is language dependent, while an indirect route is used during arithmetic approximation and thought to be language independent. The arithmetic double route has been incorporated on the triple- code model that consists of visual arabic code for identifying strings of digits, magnitude code for knowledge in numeral quantities, and verbal code for rote arithmetic fact. Our goal is to investigate whether language experience has an effect on the processing of exact/approximation math using bilingual participants who have access to two languages, using a theoretical arithmetic processing model, which has been validated across many studies. We have measured the two groups (monolinguals/bilinguals) processing speed for completing the two tasks (Exact/Approximation) in two codes (Arabic digit/Verbal). We hypothesized a faster reaction time in exact arithmetic task in compared to approximation in accordance with the triple-code model. We alsoexpected a main effect for the task (Exact vs.Approximation) independent of the input code when the stimulus was presented in either Arabic digit and/or verbal codes. Our results show exact arithmetic is faster than approximation of arithmetic facts in all codes supporting earlier theories. Also, there was no significant difference in processing speed between monolinguals and bilinguals when performing the arithmetic task in either Arabic and/or verbal codes. In addition, our investigation suggests a modification to the triple-code model when interpreting arithmetic facts in verbal code due to interference of two languages with bilingual participants. Additions to the model can be suggested when the stimulus is expressed in verbal code for visual identification, which may cause interference in bilinguals leading to a first language advantage due to language experience.

- Abstract/Description

The purpose of this study was to determine if there is an influence of bilingualism as well as musical experience and training on performance during tasks of executive function using electrophysiological (EEG) measures. The aims included: 1) analyzing differences across groups of bilinguals, monolinguals, bilingual musicians, and monolingual non-musicians on executive function tasks in their performance as well as in their corresponding event-related potentials (ERPs) to evaluate the effects...
Show moreThe purpose of this study was to determine if there is an influence of bilingualism as well as musical experience and training on performance during tasks of executive function using electrophysiological (EEG) measures. The aims included: 1) analyzing differences across groups of bilinguals, monolinguals, bilingual musicians, and monolingual non-musicians on executive function tasks in their performance as well as in their corresponding event-related potentials (ERPs) to evaluate the effects of experience-dependent neuroplasticity, and 2) correlating the ERP measures during executive function tasks with measures of bilingualism and musical training. We used three questionnaires to determine the level of bilingualism, years of instrument use, and musical experience, which were provided online in the first phase of the study through Qualtrics. For the second in-person testing phase of the study, three cognitive tasks that measured stimulus evaluation and working memory (Oddball), response inhibition (Go/No-Go), and cognitive flexibility (Wisconsin Card Sorting Test; WCST) were administered. Also, three behavioral tasks: Digit Span, Short Term Visual Memory Binding, and Corsi block tapping test assessed differences in working memory across the groups. Latency differences were observed for bilingual musicians in Standard trials at frontal electrodes, and faster reaction times to Deviant stimuli were observed in bilingual musicians compared to bilinguals, with no other significant results in response inhibition and cognitive flexibility. Therefore, this study demonstrated that musical experience may influence an individual’s speed in performing a task that uses working memory and stimulus evaluation of unexpected stimuli, as well as in their cognitive efficiency of updating as reflected by earlier peaks in the P300 ERP component.

An EEG experiment was design to test the influence of level of proficiency on processing of emotion content between languages in a sample of Spanish-English bilinguals divided by proficiency levels between two groups of bilinguals, one group of balanced (n=23) and another of unbalanced bilinguals (n=26). The participants rated words in three categories (negative, neutral, and positive) in terms of emotional valence in English and Spanish while EEG was recorded. Event-related potentials were...
Show moreAn EEG experiment was design to test the influence of level of proficiency on processing of emotion content between languages in a sample of Spanish-English bilinguals divided by proficiency levels between two groups of bilinguals, one group of balanced (n=23) and another of unbalanced bilinguals (n=26). The participants rated words in three categories (negative, neutral, and positive) in terms of emotional valence in English and Spanish while EEG was recorded. Event-related potentials were calculated for two components related to emotion processing: the early posterior negativity (EPN) and the late positive complex LPC. 2 (Bilingual group) x 2 (language) x 3 (valence) x 3 (electrode) analyses were conducted on each component, separately for latency and amplitude. The results for the EPN latency indicated a marginally significant valence effect, with emotion words presenting shorter latencies than neutral words across conditions indicating a processing advantage of emotion content in both languages. The EPN amplitude also reflected the effect of valence, with larger amplitudes both emotion categories than for neutral words. The overall EPN amplitude was larger in Spanish than in English for both bilingual groups across valence categories. The LPC latency was longer in English than in Spanish for both bilingual groups, possibly related to Spanish being identified as native language in most of the sample. The LPC amplitude was larger for negative than for emotion than for neutral words for both groups in English and in Spanish for the Balanced group. The Unbalanced group, however, presented larger for positive than for neutral, and for neutral than for negative words. These results suggest that the Balanced and Unbalanced groups process emotion content similarly in English, but differently in Spanish. The Valence effects were consistent across languages for the Balanced group, but not for the Unbalanced group which might reflect an attenuation of the valence effect for negative words in Spanish for this group, and could indicate weaker emotional reactivity to negative words in the less proficient language.

Controversy surrounds the idea that bilingualism leads to enhanced executive function (EF) and brain volume changes, potentially leading to delays in cognitive decline and dementia onset. The purpose of this research was to explore these claims in a sample of elderly monolinguals and bilinguals. This study explored gray matter volume (GMV) in 214 monolinguals and bilinguals (Mage = 71.21, SD = 7.53) who were cognitively normal (CN) or diagnosed with Mild Cognitive Impairment (MCI) or dementia...

The purpose of this research was to explore these claims in a sample of elderly monolinguals and bilinguals. This study explored gray matter volume (GMV) in 214 monolinguals and bilinguals (Mage = 71.21, SD = 7.53) who were cognitively normal (CN) or diagnosed with Mild Cognitive Impairment (MCI) or dementia. Neuropsychological performance was also examined between CN and MCI monolinguals and bilinguals (N = 153) across two visits. Scores from the Digit Span Backwards, Stroop interference, Trail Making Test A minus Trail Making Test B, and category fluency average scores were used. Magnetic Resonance Imaging (MRI) brain regions associated with memory, language, and EF were selected. Additionally, the study examined how a Bilingualism Index (BI) and the age of acquisition of English could predict GMV and EF in Spanish/English bilinguals whose native language was Spanish. Lastly, the initial age of cognitive decline across language groups was compared. Results suggested higher GMV in language and EF regions in bilinguals, but differences were not found in memory regions. Furthermore, neuropsychological performance over time did not vary across language groups; however, bilinguals exhibited reduced Stroop interference as well as lower scores on Digit Span Backwards and category fluency. The age of acquisition of English did not predict GMV or EF scores, while the BI predicted category fluency, with lower scores associated with a higher degree of balanced bilingualism. Overall, the influence of bilingualism appears to be reflected in increased GMV in specific language and EF regions relative to neuropsychological performance.
