  • The Effect of Evaluating Self's Emotions on Frontal Alpha Asymmetry

    Masato Ito, Toru Takahashi, Yuto Kurihara, Rieko Osu

    Brain and Behavior   15 ( 3 )  2025.03  [Refereed]

    　View Summary

    ABSTRACT

    Purpose

    In research to assess emotions from biometric signals, participants are asked to evaluate the emotions they subjectively experienced to confirm whether the assumed emotions were actually elicited. However, the evaluation of emotion may influence the biometric signals related to the emotion itself. While such evaluative processes may function as a form of emotion regulation, which is known to modulate emotional experiences, the neural mechanisms and effects of evaluation itself remain unclear. Specifically, the temporal dynamics of how these evaluations affect emotion‐related brain activity in electroencephalography (EEG) have not been investigated. Based on theories of emotional processing and self‐focused attention, we hypothesized that emotion evaluations would enhance emotional processing as reflected in frontal alpha asymmetry (FAA) through both immediate attentional effects and sustained self‐focused attention.

    Method

    We measured a 29‐channel EEG in 40 healthy participants who were presented with unpleasant and highly arousing images. Participants were assigned to either an experimental group that performed the task with subjective evaluation followed by without subjective evaluation, or a control group that performed the task without subjective evaluation twice. This design allowed us to examine both immediate effects of evaluation and its lasting influence on subsequent emotional processing.

    Finding

    The results revealed that FAA was significantly lower during emotional evaluation compared to conditions without subjective evaluation, particularly during stimulus processing (300–500 ms). This early modulation suggests that evaluation automatically engages attentional processes, may reflect enhanced negative emotional processing as well as the activation of behavioral inhibition system through self‐focused attention.

    Conclusion

    This study demonstrates that the emotional evaluation procedure itself can significantly alter early emotion‐related brain activity, providing insights into how self‐focused emotional evaluation engages both emotional and motivational processes. These findings suggest the need for methodological reconsiderations in EEG emotion estimation studies.

  • A cross-cultural examination of bi-directional mentalising in autistic and non-autistic adults

    　View Summary

    <p>So-called ‘mismatch accounts’ propose that, rather than arising from a socio-cognitive deficit present in autistic people, mentalising difficulties are the product of a mismatch in neurotype between interaction partners. Although this idea has grown in popularity over the recent years, there is currently only limited empirical evidence to support mismatch theories. Moreover, the social model of disability such theories are grounded in demands a culturally situated view of social interaction, yet research on mentalising and/or autism is largely biased towards western countries, with little knowledge on how successful mentalising is defined differently, and how tools to assess socio-cognitive ability compare, across cultures. Using a widely employed mentalising task, the current study investigated and compared the bi-directional mentalising performance of British and Japanese autistic and non-autistic adults and assessed observer-agent kinematic similarity as a potential dimension along which mismatches may occur between neurotypes. Participants were asked to depict various mental state- and action-based interactions by moving two triangles across a touch-screen device, before viewing and interpreting stimuli generated by other participants. In the UK sample, our results replicate a seminal prior study in showing poorer mentalising abilities in non-autistic adults for animations generated by the autistic group. Crucially, the same pattern did not emerge in the Japanese sample, where there were no mentalising differences between the two groups. Limitations of the current study include that efforts to match all samples within and across cultures in terms of IQ, gender and age were not successful for all comparisons, but control analyses suggest this did not affect our results. Furthermore, any performance differences were found for both the mental state- and action-based conditions, mirroring prior work and raising questions about the domain-specificity of the employed task. Our results add support for a paradigm shift in the autism literature, moving beyond deficit-based models and towards acknowledging the inherently relational nature of social interaction. We further discuss how our findings suggest limited cultural transferability of common socio-cognitive measures rather than superior mentalising abilities in Japanese autistic adults, underscoring the need for more cross-cultural research and the development of culturally sensitive scientific and diagnostic tools.</p>

  • Tackling social anxiety with targeted brain stimulation: investigating the effects of transcranial static magnetic field stimulation on self-focused attention

    Nozomi Tomita, Hiroki Katayama, Yuto Kurihara, Toru Takahashi, Sumiya Shibata, Tatsuya Mima, Rieko Osu, Hiroaki Kumano

    Frontiers in Behavioral Neuroscience   18  2024.03  [Refereed]

    　View Summary

    Previous studies suggested that self-focused attention (SFA), implicated in social anxiety disorder (SAD), correlates with heightened activity in the right frontopolar area (rFPA), which is the right prefrontal cortex just behind the forehead. Transcranial static magnetic field stimulation (tSMS) is a non-invasive brain stimulation method capable of temporarily suppressing brain function beneath the magnet. We explored whether tSMS on individuals with tendencies toward SAD elicited (1) suppressing rFPA activation during the resting-state and (2) reducing SFA during a subsequent speech task. Twenty-three university students with social anxiety performed two speech tasks. Between tasks, the tSMS group received neodymium magnet stimulation while the sham group received fake magnet stimulation on the rFPA for 20 min. Resting-state rFPA activities was measured using functional near-infrared spectroscopy (fNIRS), while SFA (body sensations and observer perspective), field perspective, and detached mindfulness (DM) perspective were assessed via questionnaires during both speech tasks. The observer perspective means SFA to self-imagery from others’ viewpoint, while the field and DM perspectives mean appropriately focusing on the external environment. The results indicated that tSMS intervention decreased rFPA activity from pre- to post-intervention rest. Then, tSMS reduced SFA to bodily sensations and increased DM perspective from pre- to post-intervention speech, especially in those with high levels of social anxiety. Furthermore, tSMS enhanced the field perspective regardless of social anxiety tendency. The results suggest that tSMS may suppress overactivity in rFPA, reduce SFA to body sensation, and increase adaptive attention in highly socially anxious individuals. Our study suggests the possibility of the clinical application of tSMS for treating SAD.

  • The topology of interpersonal neural network in weak social ties

    Yuto Kurihara, Toru Takahashi, Rieko Osu

    Scientific Reports   14 ( 1 )  2024.02  [Refereed]

    　View Summary

    Abstract

    The strategies for social interaction between strangers differ from those between acquaintances, whereas the differences in neural basis of social interaction have not been fully elucidated. In this study, we examined the geometrical properties of interpersonal neural networks in pairs of strangers and acquaintances during antiphase joint tapping. Dual electroencephalogram (EEG) of 29 channels per participant was measured from 14 strangers and 13 acquaintance pairs.Intra-brain synchronizations were calculated using the weighted phase lag index (wPLI) for intra-brain electrode combinations, and inter-brain synchronizations were calculated using the phase locking value (PLV) for inter-brain electrode combinations in the theta, alpha, and beta frequency bands. For each participant pair, electrode combinations with larger wPLI/PLV than their surrogates were defined as the edges of the neural networks. We calculated global efficiency, local efficiency, and modularity derived from graph theory for the combined intra- and inter-brain networks of each pair. In the theta band networks, stranger pairs showed larger local efficiency than acquaintance pairs, indicating that the two brains of stranger pairs were more densely connected. Hence, weak social ties require extensive social interactions and result in high efficiency of information transfer between neighbors in neural network.

    Scientific Reports   12 ( 1 )  2022.04  [Refereed]

    　View Summary

    Abstract

    Inter-brain synchronization is enhanced when individuals perform rhythmic interpersonal coordination tasks, such as playing instruments in music ensembles. Experimentally, synchronization has been shown to correlate with the performance of joint tapping tasks. However, it is unclear whether inter-brain synchronization is related to the stability of interpersonal coordination represented as the standard deviation of relative phase (SDRP). In this study, we simultaneously recorded electroencephalograms of two paired individuals during anti-phase tapping in three interactive tapping conditions: slow (reference inter-tap interval [ITI]: 0.5 s), fast (reference ITI: 0.25 s), and free (preferred ITI), and pseudo tapping where each participant tapped according to the metronome sounds without interaction. We calculated the inter-brain synchronization between pairs of six regions of interest (ROI): frontal, central, left/right temporal, parietal, and occipital regions. During the fast tapping, the inter-brain synchronization significantly increased in multiple ROI pairs including temporoparietal junction in comparison to pseudo tapping. Synchronization between the central and left-temporal regions was positively correlated with SDRP in the theta in the fast condition. These results demonstrate that inter-brain synchronization occurs when task requirements are high and increases with the instability of the coordination.

  • Development and validation of new evaluation scale for measuring stroke patients’ motivation for rehabilitation in rehabilitation wards

    Taiki Yoshida, Yohei Otaka, Shin Kitamura, Kazuki Ushizawa, Masashi Kumagai, Yuto Kurihara, Jun Yaeda, Rieko Osu

    PLoS ONE   17 ( 3 ) e0265214 - e0265214  2022.03  [Refereed]

    　View Summary

    Objective

    This study aimed to develop the Motivation in stroke patients for rehabilitation scale (MORE scale), following the Consensus-based standards for the selection of health measurement instruments (COSMIN).

    Method

    Study participants included rehabilitation professionals working at the convalescent rehabilitation hospital and stroke patients admitted to the hospital. The original MORE scale was developed from an item pool, which was created through discussions of nine rehabilitation professionals. After the content validity of the scale was verified using the Delphi method with 61 rehabilitation professionals and 22 stroke patients, the scale’s validity and reliability were examined for 201 stroke patients. The construct validity of the scale was investigated using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and item response theory analysis. Cronbach’s alpha confirmed its internal consistency. Regarding convergent, discriminant, and criterion validity, Spearman’s rho was calculated between the MORE scale and the Apathy Scale (AS), Self-rating Depression Scale (SDS), and Visual Analogue Scale (VAS), which rates the subjective feelings of motivation.

    Results

    Using the Delphi method, 17 items were incorporated into the MORE scale. According to EFA and CFA, a one-factor model was suggested. All MORE scale items demonstrated satisfactory item response, with item slopes ranging from 0.811 to 2.142, and item difficulty parameters ranging from -3.203 to 0.522. Cronbach’s alpha was 0.948. Regarding test-retest reliability, a moderate correlation was found between scores at the beginning and one month after hospitalization (rho = 0.612. p &lt; 0.001). The MORE scale showed significant correlation with AS (rho = -0.536, p &lt; 0.001), SDS (rho = -0.347, p &lt; 0.001), and VAS (rho = 0.536, p &lt; 0.001), confirming the convergent, discriminant, and criterion validity, respectively.

    Conclusions

    The MORE scale was verified as a valid and reliable scale for evaluating stroke patients’ motivation for rehabilitation.

  • 非侵襲的脳刺激による個体間脳波オシレーションのモジュレーション効果検証

    2024  

    　View Summary

    人インタラクションの場面では、二者間の脳活動が同期する現象が観察されている。しかし、対人インタラクションと脳間同期の共起に関する因果関係については、まだ十分に解明されていない。そこで本研究では、右側頭頭頂接合部（rTPJ）をターゲットとし、二人同時に経頭蓋交流電気刺激（hyper-tACS）を、交互タッピング課題中に実施した。tACSを用いることで、特定の脳波周波数帯域に対してモジュレーションを行うことができる。刺激周波数として6 Hz（シータ帯域）、10 Hz（アルファ帯域）、20 Hz（ベータ帯域）の3条件と、位相モードとして同位相・逆位相の2条件を設定し、これらを組み合わせた3×2の被験者内計画を実施した。パイロットスタディとして、3ペア（計6名）を対象に実験を行った。タッピング直後には、互いに協働して作業できたと感じたかを測定するため、Joint Agencyに関するVisual Analog Scale（VAS）形式の質問紙に回答してもらった。各周波数帯域における同位相刺激と逆位相刺激の差を検討したところ、6 Hz刺激のみ同位相刺激のほうが逆位相刺激よりもJoint Agencyの得点が高い傾向が認められた。以上より、rTPJにおける脳間同期がJoint Agencyの生成に寄与している可能性が示唆される。今後はさらに実験参加者を増やすとともに、シャム刺激（sham）条件との比較を進めていく予定である。

  • 対人インタラクション中の個体間脳波同期に着目した二重共感理論へのアプローチ

    2023  

    　View Summary

    自閉スペクトラム症者（ASD者）が対人インタラクション（以下，インタラクション）を苦手としているのは，相手が定型発達者（TD者）のときであり，相手がASD者の場合はインタラクションが円滑に行える可能性が示唆されており、これを二重共感問題の理論と呼ぶ。本研究では、二重共感問題の理論が二者間における脳波の同期性から立証できるか検証を行った。過去の研究では相互の予測を伴うインタラクション中にお互いの脳波同期の程度が高くなることが示されている（Kurihara et al. 2022,&nbsp;Sci. Rep.）。これを踏まえ、相互予測を伴うdual-Ball Catch Task（野球におけるフライボールを参加者2人のどちらかがキャッチする心理実験課題）を作成した。12ペアを対象に、dual-Ball Catch課題中の脳波を2人同時に計測し、ASD傾向を測る尺度（Autism Quotient; AQ）を取得した。その結果、ボールを落とさず上手に課題を行えているペアで、高いアルファ（8-12Hz）の脳波同期がみられた。今後は取得したAQについても解析し、二重共感問題の理論について検証を行っている予定である。
