I. Introduction

II. Methods

  • INTRODUCTION

  • This study focuses on a set of three questions regarding language learning in bilinguals and monolinguals

  • Does being bilingual facilitate subsequent language acquisition?

  • How does bilingualism facilitate the acquisition of a third language (L3)?

  • If there are multiple ways in which L3 learners benefit from being bilingual, how do these effects interact?

  • HYPOTHESES

  • Domain general: Being bilingual makes learning an L3 easier because of the cognitive advantages associated with bilingualism. These advantages include enhanced attention and executive control (Bialystok & Craik, 2008).

  • Domain Specific: Knowing a wider range of certain linguistic features facilitates the learning of new but related features.

  • Cumulative: The domain general and domain specific effects are additive, thus allowing bilinguals to benefit from general cognitive advantages and language-specific experience.

  • BILINGUALISMAND SUBSEQUENT LANGUAGE LEARNING

  • Kaushanskaya & Marian (2009a & b): Bilingualism facilitates L3 acquisition due to general cognitive advantages

  • Best (1995): An “attuned” perceptual system possesses an increased ability to acquire information to which it has become sensitized

  • Best et al (2001): Discrimination of non-native contrasts facilitated if phonologically equivalent to native contrasts

  • Sanz, (2000): Bilingual education has a positive effect on L3 acquisition

  • Cenoz & Valencia (1994), Swain et al (1990): Literacy in multiple languages improves L3 acquisition

  • CURRENT STUDY

  • The goal of the current study is to determine whether the domain general, domain specific, or cumulative hypothesis is true for the acquisition of a third language. By determining which hypothesis is true, the benefits of bilingual education and bilingualism can be better understood.

  • PARTICIPANTS

  • Paid Northwestern University participants

    • 12 Mandarin-English bilinguals

    • 12 English monolinguals

  • MATERIALS

  • Female speaker of Gujarati

  • Mandarin-like language (ML): 8 sound stimuli containing a Mandarin feature (retroflex consonants)

    • /ti/, /te/, /tu/, /to/, /ʈi/, /ʈe/, /ʈu/, /ʈo/

  • English-like language (EL): 8 sound stimuli containing an English feature (fricative voicing)

    • /βi/, /βe/, /βu/, /βo/, /ɸi/, /ɸe/, /ɸu/, /ɸo/

  • Normalized for pitch and amplitude

  • 16 different pictures each paired with a stimulus

    • Sample pictures:

  • PROCEDURE

  • Participants sit in a sound booth equipped with a monitor to display pictures

    • Participants are provided with a keyboard to input responses and a set of headphones to hear stimuli

  • TRAINING: Participants learn one artificial language (15 minutes of training)

    • No responses necessary during training

  • TEST: Participants complete a word-picture pairing test (10 minutes)

    • Participants are presented with a full set of 8 pictures on the monitor

    • Each picture is paired with a corresponding number

    • Stimuli are presented consecutively

    • Following each presentation, participants are given time to choose the picture paired with the stimulus

    • Participants input their response using the number pad on the keyboard

  • Repeat with second language

    • Counter-balanced languages between subjects

IV. Discussion

  • PREDICTION

  • Cumulative hypothesis was predicted to be correct

  • English monolinguals would perform worse on both EL and ML

  • Mandarin bilinguals would perform better on ML and English monolinguals would perform better on EL

  • ACTUAL RESULTS

  • Domain general hypothesis most well-supported

  • Mandarin-English bilinguals outperformed English monolinguals overall in both languages

  • No domain specific effect = No cumulative effects

  • RELATIVE DIFFICULTYOF EL

  • Reaction times suggest that EL is a more difficult language than ML

  • Explains discrepancy between expected accuracies of bilingual and monolingual groups and actual results

  • Speed-accuracy tradeoff also suggests relative difficulty of EL

  • More time needed for EL despite worse accuracy by both groups

  • DOMAIN GENERAL HYPOTHESIS

  • Bilinguals have an advantage in subsequent language learning

  • The domain general hypothesis was most well-supported

  • Mandarin-English bilinguals better at both languages

  • Both groups better at ML, although reaction times suggest that ML was an easier language overall

  • No evidence for domain specific hypothesis because English monolinguals did not perform better on EL

  • FUTURE WORK

  • Follow-up experiment will compare Korean-English bilinguals and Mandarin-English bilinguals

  • Domain specific evidence possibly lacking due to increased difficulty of EL relative to ML

  • Can possibly find domain specific evidence by controlling for difficulty of artificial languages

  • Evidence also more likely to be found because two bilingual groups will be compared

  • Will reveal whether bilingual advantages are due to previous experience with specific language features

  • Artificial language based on Korean phonology will be created

  • Vowels will remain identical to those used in EL and ML

  • Domain general, domain specific, and cumulative hypotheses will once again be considered

Figure 1: Predicted results (Cumulative effect)Y-axis indicates degree of accuracy. Note that English monolinguals perform better on ML than Mandarin-English bilinguals perform on EL. However, the better performance of bilinguals across both languages is due to cumulative domain general and domain specific effects.

Figure 2: Comparative accuracy of both groups

p = 0.007** between groupsp = 0.098* between languages

Mandarin-English BilingualsML accuracy = 87%, EL accuracy = 81%

p = 0.35

English MonolingualsML accuracy = 77%, EL accuracy = 68%

p = 0.191

Results suggest that EL may have been more difficult

Explains discrepancy between expected scores and actual scores for English monolinguals

Figure 3Comparative reaction times of both groups

p = 0.519 between groupsp = 0.006** between languages

Mandarin-English BilingualsML reaction time = 0.221 second/answerEL reaction time = 0.26 second/answer

p = 0.096*

English MonolingualsML reaction time = 0.219 second/answerEL reaction time = 0.265 second/answer

p = 0.009**

Both groups reacted slower during testing of EL

Performance is significantly different

Speed differences between groups were not significant but speed differences within groups were significant
