The role of the extended amygdala and amygdala in mediating emotion and inhibitory control in native language versus second language processing is currently not well understood. The current study examined activity in the extended amygdala and amygdala when twelve healthy young adults were exposed to emotional-linguistic stimuli in either their native language (i.e., Japanese) or in a second language (i.e., English) using a go/no-go task while undergoing fMRI scans. Data was bootstrapped using random resampling. A significant interaction was observed for the amygdala and extended amygdala activity for language (English vs. Japanese), emotional-linguistic valence (positive, negative, neutral) and inhibitory control (go/no-go condition). Furthermore, main effects were observed for language and valence for the amygdala and extended amygdala. Main effects were observed for inhibitory control for the extended amygdala and right amygdala but not for the left amygdala, which did not show a main effect for inhibitory control. Significant interactions and main effects were also observed for behavioral outcomes (go/no-go reaction time and accuracy scores) for the amygdala and extended amygdala. Post hoc analyses found that under conditions of inhibitory control participants had less activation in the extended amygdala and amygdala when processing emotional information in English (i.e., second language) compared to Japanese (i.e., native language). In summary, our findings suggest that the amygdala and extended amygdala may mediate emotion and inhibitory control when participants process information in their native (Japanese) versus a second language (English).

Abstract

The current study examined the relationship between trait emotional intelligence (TEI), academic stress, burnout, and engagement in Japanese undergraduate students learning English as a second language. One hundred eighty-four participants (females = 87, mean age = 19.7 years) completed two questionnaires, one administered at the beginning of the academic semester (i.e., baseline), and one administered at the end of the academic semester (i.e., follow-up). Structural equation modeling revealed that TEI factors predicted engagement and negatively predicted academic stress, while stress strongly predicted burnout. Cluster analysis and ANOVA revealed that participants with high TEI reported significantly lower scores for stress and burnout and higher scores for academic engagement (i.e., emotional and agentic) compared to participants with low TEI. In addition, exhaustion significantly increased between baseline and follow-up for participants with low TEI but not for participants with high TEI. For participants with high TEI, inadequacy significantly decreased whereas emotional engagement significantly increased between baseline and follow-up. Results suggest that increasing TEI may reduce academic stress and burnout while increasing engagement among second language learners in a Japanese context.

The role of positive and negative psychological factors in predicting effort and foreign language anxiety for languages other than English (LOTE) is not well understood. Therefore, two hundred twenty-one students attending a private university in Tokyo, Japan participated in a research study. Participants were studying one of four LOTEs, specifically Chinese (n = 41), Spanish (n = 76), French (n = 62) or German (n = 42). Students spent, on average, more than two years studying each respective LOTE. Questionnaire surveys were used to assess the following constructs: integrative orientation, intrinsic motivation, introjected regulation, teacher and parental support, intended effort for learning the LOTE and LOTE anxiety. Descriptive statistics and regression analyses were conducted to assess the data. Complex and diverse interrelationships among teacher and parental supports, positive and negative orientations, and outcome variables (intended effort and anxiety) were observed in each LOTE.

The current study had two objectives: (a) to quantitatively investigate whether Japanese language learners of English have inclusive second language (L2) self-related motivations, and how inclusive L2 self-related motivations contribute to English learning effort and self-rated English ability, and (b) to qualitatively examine how Japanese learners of English incorporate parental expectations and values about English into their L2 self during each stage of their English learning experience, and how higher and lower English proficiency learners incorporate parental values and opinions into their L2 self. We found that an inclusive L2 self-related motivation explained the interaction between social/contextual factors and English learning effort or self-rated English ability. A gap was observed between higher and lower English proficiency groups regarding the degree of incorporating parental expectations, values, and feelings about English into their sense of L2 self. Having an inclusive L2 self successfully introduces different viewpoints into current self-related motivational frameworks within language learning contexts, which to date have only emphasised individual levels of self perspectives to the exclusion of inclusive self figures derived from social surroundings.
