“…We only had data for an L2 contrast and, thus, it is possible that our cohort of bilinguals favored English over Spanish. It is also possible that the robust L2 speech processing indicated that the early bilinguals we tested were able to adjust their phonological contrasts based on linguistic contexts (see Casillas & Simonet, 2018). We did not attempt to manipulate context, and the experimental setting decidedly favored English, with the consent and instructions carried out in English.…”

Automaticity of speech processing in early bilingual adults and children

We examine whether early acquisition of a second language (L2) leads to native-like neural processing of phonemic contrasts that are absent in the L1. Four groups (adult and child monolingual speakers of English; adult and child early bilingual speakers of English and Spanish, exposed to both languages before 5 years of age) participated in a study comparing the English /ɪ/ - /ε/ contrast. Neural measures of automatic change detection (Mismatch Negativity, MMN) and attention (Processing Negativity, PN and Late Negativity, LN) were measured by varying whether participants tracked the stimulus stream or not. We observed no effect of bilingualism on the MMN, but adult bilinguals differed significantly from adult monolinguals on neural indices of attention. The child bilinguals were indistinguishable from their monolingual peers. This suggest that learning a L2 before five years of age leads to native-like phoneme discrimination, but bilinguals develop increased attentional sensitivity to speech sounds.

“…First, as was noted elsewhere, future research should include both discrimination and identification tasks because those tasks may tap into different perceptual skills involved in different stages of perceptual learning. Likewise, it would be beneficial to control for language mode within the study, encouraging L2 processing by providing materials and instructions in the L2 whenever possible, given that even novice learners may demonstrate dual perceptual boundaries (Casillas & Simonet, 2018; Gonzales, Byers‐Heinlein, & Lotto, 2019). With respect to the production tasks, the participants in the present study may have been able to use the auditory form presented during delayed repetition to enhance their production.…”

Revisiting Perception–Production Relationships: Exploring a New Approach to Investigate Perception as a Time‐Varying Predictor

Models of L2 pronunciation learning have hypothesized that accurate speech perception promotes accurate speech production. This claim can be evaluated longitudinally by examining the extent to which changes in stop consonant perception predict changes in stop consonant production. Taking a time‐sensitive view of the perception–production link, this study used longitudinal data to analyze perception as a time‐varying predictor of production accuracy. Mixed‐effects models were fit to oddity, delayed word repetition, and picture description tasks to examine how participants’ perception and production changed over time. Oddity task perception data were then decomposed into their between‐ and within‐subjects components and integrated into the delayed repetition and picture description production models. Surprisingly, only the between‐subjects predictors reached significance, and the strength of the perception–production link varied across production tasks and target phones. The methods used have implications for future research on perception–production links.

“…Previous studies have used perceptual cues, including conversations, videos, and/or magazines to create influential language contexts in bilinguals’ speech perception (Antoniou et al, 2012; Casillas & Simonet, 2018; Elman et al, 1977; Flege & Eefting, 1987a; García-Sierra et al, 2009; 2012; Gonzales & Lotto, 2013; Hazan & Boulakia, 1993). However, this design cannot disambiguate if the bottom-up properties, or rather the top-down conceptual knowledge, provided by the perceptual cues themselves primarily influenced the observed double phonemic boundary effect.…”

“…Other investigations have shown that bilinguals remain sensitive to the linguistic properties of perceptual cues and preferentially tailor speech processing towards the most appropriate language (Casillas & Simonet, 2018; Gonzales & Lotto, 2013; Ju & Luce, 2004; Lagrou, Hartsuiker & Duyck, 2011). In an eye-tracking paradigm targeting bilinguals’ lexical access, Ju and Luce (2004) presented highly proficient Spanish–English bilinguals four pictures of objects along with a spoken Spanish target word that always began with a voiceless stop consonant (i.e., /p, t, k/).…”

“…This leads Spanish–English bilinguals to perceptually shift their boundary towards negative VOT in Spanish contexts and towards long lags in English contexts when language contexts are established before, and throughout, behavioral tasks (Casillas & Simonet, 2018; Elman, Diehl & Buchwald, 1977; Flege & Eefting, 1987a; García-Sierra, Diehl & Champlin, 2009; Gonzales & Lotto, 2013; Gonzales, Byers-Heinlein & Lotto, 2019), and passive listening tasks that measure the neural activity associated with speech sound discrimination (García-Sierra, Ramírez-Esparza, Silva-Pereyra, Siard & Champlin, 2012). Bilinguals whose languages share similar phonetic structures to that of Spanish and English also have shown a similar pattern (Antoniou, Tyler & Best, 2012; Hazan & Boulakia, 1993).…”

Matching the Mismatch: The interaction between perceptual and conceptual cues in bilinguals’ speech perception

Speech perception involves both conceptual cues and perceptual cues. These, individually, have been shown to guide bilinguals’ speech perception; but their potential interaction has been ignored. Explicitly, bilinguals have been given perceptual cues that could be predicted by the conceptual cues. Therefore, to target the perceptual-conceptual interaction, we created a restricted range of perceptual cues that either matched, or mismatched, bilinguals’ conceptual predictions based on the language context. Specifically, we designed an active speech perception task that concurrently collected electrophysiological data from Spanish–English bilinguals and English monolinguals to address the extent to which this cue interaction uniquely affects bilinguals’ speech sound perception and allocation of attentional resources. Bilinguals’ larger MMN-N2b in the mismatched context aligns with the Predictive Coding Hypothesis to suggest that bilinguals use their diverse perceptual routines to best allocate cognitive resources to perceive speech.
