Student Research Spotlight: Working Memory in Spanish–English and Chinese–English Bilinguals

Working Memory in Spanish–English and Chinese–English Bilinguals 



Speaking more than one language has its benefits.  For example, bilinguals have demonstrated greater working memory capacity when compared to monolinguals in numerous studies. But what is it about bilingualism that may lead to such an advantage? And are all bilinguals equally benefitted despite similarity or dissimilarity of the languages they speak?  

Suet Mui Ma (Debby), a senior at Brigham Young University-Hawaii, hypothesized that Chinese-English bilinguals would have a greater working memory on visual-spatial task than Spanish-English bilinguals, while controlling for language proficiency and gender differences.  Debby was inspired, as a bilingual student, to investigate this area as she has had personal experience in the perceived discrepancies between different language speakers.

Students from a diverse multicultural University were recruited for her study.  Participants were proficient in two languages, either Spanish-English or Chinese-English. Participants were given self-rated language proficiency questions from the American Council Teaching of Foreign Languages (ACTFL).  Participants then engaged in a paper folding task to measure working memory. This task involved mental rotation and serial operations.  The results supported the hypothesis that Chinese-English bilinguals have greater working memory than Spanish-English bilinguals.

What was most challenging and most exciting thing about your study?

"Finding Chinese-English bilinguals was the easy part because of my connections.  However, Spanish-English bilinguals are hard to come by.  It took a lot of face-to-face invitation and social media outreach to find participants for my study.  After running the statistics, my first results were not significant.  Then I decided to use an ANCOVA to control for gender and self-reported English level.  Then I got really excited; my results were significant! My hypothesis that Chinese-English bilinguals would have a greater working memory than Spanish-English bilinguals was supported!"

What were some interesting experiences you had while conducting your study?

"Observing the subjects while participating in the study was so interesting.  You could see the reaction differences between the two groups of bilinguals.  There was definitely a difference in the speed of Spanish-English bilinguals compared to Chinese-English bilinguals.  Both groups showed struggles in the task as they scratched their heads and mumbled to themselves."

What advice would you give other undergraduate students prior to conducting their own psychological research?

"I would recommend students to take some fundamental psych classes before they conduct their own psychological research.  The more classes they take, the more ideas they will have for their research.  From my own experience, I took most of the psych classes before conducting my research.  After taking multivariate statistics and biopsychology, it was a lot easier for me to find research on my topic as well as finding the best analyses for my experiment.  Attending psychology research labs (496R) is very valuable.  It helps students to know more about the processes of doing research.  PSYC 496R preveiews PSYC 305 and 490, as students get the hands-on experience in research."

Debby plans to graduate in the Fall of 2016 from Brigham Young University-Hawaii as a psychology major.  In the Spring of 2016, Debby presented her study in China at the Xi'an Conference where it then went on to get published in Psychology and Behavioral Sciences journal. Debby plans to continue her education onto graduate school in the clinical field.  She remarks learning applicable statistical analyses and having many great opportunities to participate in research and present that research to the public as an undergraduate psychology major at Brigham Young University-Hawaii.

  1. Thank you for sharing this blog. Your experiences can help a researcher like me. I am interested in the matters of Counselling PSychologists.
