The neural correlates of pausing behaviours in L2 writing
This study is the first to explore the neural correlates of cognitive processes proposed in models of writing, combining fMRI scanning with keystroke logging to bring together insights from neuroscience and behavioural research. We focused on a key writing mechanism, pausing; specifically, we examined how pause location (within words, between words/sentences) may relate to neural processes. The participants were 21 intermediate-level Japanese uni…
The neural correlates of mid- and end-clause silent pauses in L1 and L2 speech
This study examined how the location of silent pausing (mid- vs. end-clause) may relate to neural processes during spontaneous L1 and L2 speech production. Twenty intermediate-level Japanese speakers of L2 English carried out eight monologic, oral decision-making tasks, four in English and four in Japanese. While completing the tasks, their brain activity was recorded through fMRI scanning. Participants’ speech was transcribed, and the resulting …
Neural mechanisms of attitudinal prosody in a second language
Understanding how attitudinal prosody is processed in a second language (L2) remains an open question, particularly regarding its neural mechanisms and the role of real-world experiences. Using functional magnetic resonance imaging (fMRI), we examined how native Japanese learners processed attitudinal versus linguistic prosody in their L1 (Japanese) and L2 (English) during a forced-choice judgment task. Across languages, attitudinal and linguisti…
The neural correlates of nominal classification rule learning and their individual differences
Learning a second language involves not only the acquisition of abstract grammatical rules, such as word order, but also rules based on language-specific semantic distinctions, as seen in nominal classification systems. However, little is known about the neural mechanisms underlying learning of such systems. The present study examined the neural correlates of nominal classification rule learning and the role of individual differences in working m…
Task-generated processes in second language speech production
The last three decades have seen significant development in understanding and describing the effects of task complexity on learner internal processes. However, researchers have primarily employed behavioral methods to investigate task-generated cognitive load. Being the first to adopt neuroimaging to study second language (L2) task effects, we aimed to provide novel insights into the neural correlates of task-related variation in L2 oral producti…
Reduced body-image disturbance by body-image interventions is associated with neural-response changes in visual and social processing regions
We identified distinct neural mechanisms (bodily visuospatial and socio-cognitive processing) associated with the reduction in each component of body-image disturbance. Our results imply that different neural mechanisms are related to reduced perceptual disturbance and the expression thereof, whereas similar neural mechanisms are related to the reduction and expression of affective disturbance. Considering the small sample size of this study, our…
An fMRI validation study of the word-monitoring task as a measure of implicit knowledge
In this study, neural representation of adult second language (L2) speakers’ implicit grammatical knowledge was investigated. Advanced L2 speakers of Japanese living in Japan, as well as L1 Japanese speakers, performed a word-monitoring task (proposed as an implicit knowledge test) in the MRI scanner. Behavioral measures were obtained from aptitude tests for explicit (language analytic ability) and implicit (statistical learning ability) learning…
A multifactorial framework of psychobehavioral determinants of coping behaviors
Coronavirus disease 2019 dramatically changed people's behavior because of the need to adhere to infection prevention and to overcome general adversity resulting from the implementation of infection prevention measures. However, coping behavior has not been fully distinguished from risk perception, and a comprehensive picture of demographic, risk-perception, and psychobehavioral factors that influence the major coping-behavior factors remain to b…
Does the eight-factor “power to live” in disaster exist since childhood
Background: Studies on the survivors of the 2011 Great East Japan earthquake and tsunami have revealed eight factors, called power to live, which are closely related to resilience and effective coping after intense and prolonged stress. However, whether the eight factors, which were examined in adults, are applicable to children is unclear. The purpose of this study is to evaluate whether the eight-factor structure of power to live was present si…
Does domain-general auditory processing uniquely explain the outcomes of second language speech acquisition, even once cognitive and demographic variables are accounted for
Extending the paradigm in L1 acquisition, scholars have begun to investigate whether participants’ domain-general ability to represent, encode, and integrate spectral and temporal dimensions of sounds (i.e., auditory processing) could be a potential determinant of the outcomes of post-pubertal L2 speech learning. The current study set out to test the hypothesis that auditory processing makes a unique contribution to L2 speech acquisition, for 70 …
Intentional binding and self-transcendence
Sense-of-agency (SoA) is implicated in a wide range of pro-survival behavioral capacities from a classical psychological perspective. However, in recent years, SoA has primarily been considered a sensorimotor process indexed by intentional binding, and pro-survival behavioral capacity has been considered multifactorial. To revisit their association, considering such conceptual updates, we examined the relationship between intentional binding and …
Neural mechanisms of language learning from social contexts
Humans learn languages in real-life situations by integrating multiple signals, including linguistic forms, their meanings, and the actions and intentions of speakers. However, little is known about the neural bases underlying the social learning of a second language (L2) in adults. In this study, 36 adults were asked to learn two sets of L2 spoken words through translation versus simulated social interactive videos (social learning). Brain activ…
Brain activity predicts future learning success in intensive second language listening training
This study explores neural mechanisms underlying how prior knowledge gained from pre-listening transcript reading helps comprehend fast-rate speech in a second language (L2) and applies to L2 learning. Top-down predictive processing by prior knowledge may play an important role in L2 speech comprehension and improving listening skill. By manipulating the pre-listening transcript effect (pre-listening transcript reading [TR] vs. no transcript read…
Evaluation of energy density and macronutrients after extremely brief time exposure
Anxiety increases visual attention to hedonic foods
Testing Second Language Oral Proficiency in Direct and Semidirect Settings
This study used functional magnetic resonance imaging (fMRI) to identify differences in the neural processes underlying direct and semidirect interviews. We examined brain activation patterns while 20 native speakers of Japanese participated in direct and semidirect interviews in both Japanese (first language [L1]) and English (second language [L2]). Significantly greater activation was observed in the regions involved in social communication (th…
