  • Leader–follower relationship embodied in movements during violin ensemble performances

    Itagaki Nene, Yagai Yusuke, Miura Akito, Mishima Hiroyuki, Furuyama Nobuhiro

    Cognitive Studies: Bulletin of the Japanese Cognitive Science Society   30 ( 3 ) 285 - 302  2023.09

     View Summary

    Musicians have to coordinate movements interpersonally to perform in an ensemble. As such, this study explores how violinists coordinate movements to play the same melody together in terms of the leader–follower relationships revealed by players’ movements. Twelve violinists participated in the study and played a violin ensemble in pairs. We applied Granger causality analysis to the three-dimensional displacement data of players’ heads, violins, and bows to identify leader–follower relationships between players. The results revealed the following: i) the participants adopted leader–follower roles during trials; ii) as the performance proceeded, the participants swapped roles; iii) the more difficult the parts of the score, the more notable the leader–follower relationships; iv) compared with between-head and between-violin data, the movements for between-bow data were more similar in more parts of the score that demonstrated leader–follower relationships. Further examination of cases where the leader–follower relationships were identified showed that players may have employed their own strategies to achieve a stable, coordinated state. These results suggest that, when the roles of players are not fixed in violin ensembles, performance can be adjusted in multiple ways, including swapping leader–follower roles, which is in stark contrast to previous studies that reported fixed leader–follower relationship when the first violinist only led the other parts in a string quartet.

  • Involvement of global coordinative structure in achieving the local pendulum swinging task

    Yusuke Yagai, Akito Miura, Hiroyuki Mishima, Nobuhiro Furuyama

    PLOS ONE   17 ( 2 ) e0262525 - e0262525  2022.02  [Refereed]

     View Summary

    In the literature on inter-limb coordination, the coordination among ‘‘focal’’ body parts (i.e., the two limbs) directly engaged in a pendulum swinging task has been studied by immobilizing other body parts to reduce “noise,” while putting aside questions of how one maintains posture while performing the task. However, in practical performance of musical instruments, for example, performers must coordinate different body parts in sync with the music while maintaining the whole body’s balance. This study demonstrates the effectiveness and necessity of understanding inter-limb coordination in whole-body coordination. Participants were asked to move two pendulums either in sync or alternatively with metronome beeps under two conditions: immobile (fixed forearms) and mobile (forearms not fixed). The explorative analyses focused on whether and how coordinative structures emerged and whether the degree of task achievement differed according to the phase mode, frequency, and mobility conditions. The motion similarity and phase difference between different parts and the pendulums showed that task-specific coordinative structures emerged in both immobile and mobile conditions. In the in-phase mobile condition, the emergent coordinative structure may have improved task achievement, shown by the phase difference between the left and right pendulums. These findings suggest that the global coordinative structure is involved in achieving the local pendulum swinging task.

  • How Does a Walker Pass Between Two People Standing in Different Configurations? Influence of Personal Space on Aperture Passing Methods

    Tomono, T, Makino, R, Furuyama, N, Mishima, H

    Frontiers in Psychology   10   2651  2019.12  [Refereed]

     View Summary

    Most studies on aperture passability focus on aperture passing involving non-human physical objects. In this study, we examined experimentally how participants pass between two box-shaped frames and between the same frames, each with a human confederate in it, facing various directions. Seven configuration conditions were set up, six of which differed in terms of the human confederates’ sets of directions in the two frames: face-to-face, back-to-back, facing toward or away from the participants, facing leftward or rightward from the participants’ perspective, and the empty frames condition without human confederates. There were seven aperture-width conditions—50, 55, 60, 65, 70, 75, and 80 cm—and participants walked at their normal speed through the apertures. We found that the participants’ shoulder rotation angle in the face-to-face condition was significantly greater than that in the empty frames condition. Further, the participants preferred to rotate their shoulders counterclockwise when our confederates in the aperture faced leftward, and clockwise, when they faced rightward. These results suggest that people change their passing-through methods by considering the social nature of the aperture as well as its width.

    Mariko Ito, Hiroyuki Mishima

    Ecological Psychology   30 ( 3 ) 250 - 277  2018.07  [Refereed]

    Authorship:Last author

     View Summary

    This study focuses on the perceptual skills used when playing kendama, a toy with a ball, string, and handle. It examines the visual information required for guiding the head and handle movements during the “swing-in” catching maneuver and determines whether information-based strategies such as canceling the rate of change of α (the optical depression angle from the horizon) or cot α (optical acceleration), using tau coupling, or a combination thereof, could be applied to this empirical task. The regressions of both α and cot α with time are found to be highly linear and increase when the skill level increases. For expert players, the k values for the tau coupling based on the center of the ball are clearly lower than those for the tau coupling based on the hole in the ball compared with skilled players. These results suggest that, with increasing skill level, kendama players tend to utilize α or cot α for regulating the observation point and use the sight of the hole as the tau coupling information for controlling the handle.

    【目的】 ヒトは、発達段階で視覚と体性感覚の知覚システムを同時に動員し能動的に動くことでそれらの協調を学習し、様々な環境に対して適応可能になる。今回我々は、自分の身体と支持面を見ながら能動的に動く動作が、視覚と体性感覚の協調に与える影響を姿勢制御の観点から検討した。<br>【方法】 対象は、藤田保健衛生大学倫理審査委員会の承認(10-204)の下、同意を得た健常男性40名(平均年齢22.4±2.3歳)を10名ずつ揺すり、背臥位、腹臥位、腹臥位視覚遮断(腹臥位と同一の対象)、筋トレの5群に分類。重心動揺計(サンプリング周波数10Hz)を用いて、a;視覚情報統制条件とb;鉛直情報呈示条件で30秒間の静止立位時の、c;上肢水平挙上、d;点へのリーチ、e;面へのリーチ条件で15秒間のリーチ姿勢保持時の、単位面積軌跡長(以下、L/A)を計測。各群における治療前後での変化の平均値を算出した。<br>【結果】 各条件におけるL/A(/㎜)の治療前後での変化の平均値を群ごとに示す。<br>揺すり群:a;0.07, b;0.26, c;-0.11, d;-0.01, e;0.22<br>背臥位群:a;-0.07, b;0.11, c;-0.10, d;0.18, e;0.33<br>腹臥位群:a;0.27, b;0.29, c;0.57, d;0.16, e;-0.21<br>腹臥位視覚遮断群:a;-0.06, b;0.16, c;-0.11, d;0.20, e;0.82<br>筋トレ群:a;-0.05, b;0.06, c;-0.49, d;-0.37, e;-0.56<br>【考察】 L/Aは動的、静的な姿勢制御を識別し、その程度を示す微細さの指標となる。L/Aが増加する場合、運動の拡がりに拮抗する筋活動で制御するCA(カウンターアクティビティ)の戦略が優位に、L/Aが減少する場合、支点に対して反対側の重りで釣り合いをとり静的に制御するCW(カウンターウェイト)を活性化する戦略が優位になると考えている。ここで静止立位課題について、bでは全群でCA優位となり、視覚的構造物が空間的定位の指標になったと考えられる。その内、揺すり、腹臥位群はa, bともに、すなわち視覚情報量の大小に関わらずCA優位であり、1つの知覚システムが優位に作用することなく視覚や体性感覚といった複数の知覚システムが協調したためと推察される。一方、背臥位、腹臥位視覚遮断、筋トレ群ではaでCWの活性化が優位となり、視覚情報量の差でバランス戦略が異なるため、視覚と体性感覚が乖離したと考えられる。次にリーチ姿勢保持に関して、cは腹臥位群のみ、dは背臥位、腹臥位、腹臥位視覚遮断群、eは揺すり、背臥位、腹臥位視覚遮断群でCA優位となった。腹臥位群に着目すると、身体の質量バランスが不均衡となり体性感覚への負荷が高まるcと、視覚と体性感覚に対する拘束力が強まるdでCA優位となり、体性感覚だけでなく視覚と協調しながら柔軟な姿勢制御が可能であったと考えられる。また漠然とした注意の中、広い面に触れていれば良いという体性感覚が強く作用するeでは、体性感覚の反応に視覚の反応を沿わせたためCWの活性化が優位になったと考える。<br>【まとめ】 腹臥位群のように絶えず身体と支持面の変化を見ながら能動的に動く動作により、各々の環境・条件での姿勢制御が視覚と体性感覚に対する情報量に、よりダイナミックな適応を示した。視覚と体性感覚の協調を図る運動療法の新たな展開が期待できる。

  • The Dynamical Stability of Visual Coupling and Knee Flexibility in Skilled Kendama Players

    Mariko Ito, Hiroyuki Mishima, Masato Sasaki

    ECOLOGICAL PSYCHOLOGY   23 ( 4 ) 308 - 332  2011  [Refereed]

     View Summary

    We examined the role of postural control in a skilled task that requires perceptual-motor coordination, the kendama trick "Swing-in," which uses a moving ball on a string. Four expert and 4 novice players participated, each performing 200 trials of Swing-in. The head and knee movements of the experts were more extensive than those of the novices, and the movements of the head and the ball, as well as the knee and the ball, maintained the same patterns longer in the experts than in the novices. At the end of each trial, distances between the head and the ball in the expert group were more consistent than those in the novice group, but the 2 skill groups showed similar variability in distance between the knee and the ball. These findings suggest that kendama experts controlled their body movement to dynamically coordinate them with the moving ball, and the stability of the strong coupling of the head and the ball in the experts seemed to be supported by the flexibility of knee movement.

     View Summary

    We frequently observe occasions when breathing is intentionally controlled to match to concurrent body movement. This study reports on two experiments conducted to examine the stability and variability in the coordination of breathing with wrist-movements, with an inverted pendulum held in the hand. In Experiment 1, two modes of stable coordination of breathing and wrist-movement were identified: (1) the wrist was radially-flexed during inspiration and ulnarly-flexed during expiration; and (2) the wrist was ulnarly-flexed during inspiration and radially-flexed during expiration. In Experiment 2, subjects coordinated breathing and wrist-movements as three factors (phase mode, oscillatory frequency of breathing/wrist-movements, the eigen frequency of the pendulum) were manipulated. The results indicated that the coordination of breathing and wrist-movement exhibits patterns predicted by HKB-equation (e.g., phase transitions from the intended phase mode to the unintended mode). We suggest that breathing and wrist-movement together constitute a self-organizing system and that they are governed not only by the central nervous system but are also constrained by dynamical principles.

     View Summary

    This study examined the stability and variability of interpersonal coordination, in which one person breathed while the other moved a wrist back and forth with an inverted pendulum in hand. Nine pairs of subjects coordinated each other's movement in two relative phase modes. In one mode, Radial flexion-Inspiration and Ulnar flexion-Expiration (RIUE), one subject radially flexed the wrist as the other inhaled and ulnarly flexed it as the other exhaled. In the other, Ulnar flexion-Inspiration and Radial flexion-Expiration (UIRE) mode, the wrist was ! ulnarly flexed at inhalation, and radially flexed at exhalation. Results were as follows: (1) The two were more highly coordinated in RIUE mode than UIRE mode as the frequency of oscillation increased. (2) Phase transitions were observed from URIE to RIUE mode, as the frequency of oscillation increased. And (3) the more different in preferred frequency the pendulum and breathing movements were, the more deviated from the intended relative phase the coordination became. These results suggest that interpersonal coordination of breathing and wrist-pendulum movement is qualitatively equivalent to intra personal coordination between them.

  • Perceiving affordances for switching two actions, "stepping-over" and "passing-under".

    Mishima Hiroyuki

    The Japanese journal of psychology   64 ( 6 ) p469 - 475  1994.02

     View Summary

    J. J. Gibson (1979/1986) proposed that animals perceive 'affordances', which are the functional utilities based on the properties of both the animals and the environment. If this is the case, animals should make judgements about what to do referring to the capability of their own action system. In this study, I examined a perceptual boundary between "stepping-over" and "passing-under" for two groups-the tall group and the short group. Subjects were individually requested to judge whether they would "stepover" or "passunder" a bar presented in front of them which was varied in height. I found that the mean bar-height to leg-length (B/L) ratio at the perceptual action-switching-point is invariant, or 1.07, for each group. This result suggests that animals perceive affordances in controlling action, which means that the environment for animals is structured as to various levels of action.

     View Summary

    The purpose of this study was to clarify what makes skilled drummers different from unskilled drummers, especially the relationship between local beat movements and global whole-body movements. We analyzed the performance of skilled and novice drummers on the task of playing 1/8 note beats on an electronic drum, as well as the center of pressure (CoP) data, which is representative of whole-body motion during the performance of the task. This feature is more pronounced immediately after kicking the bass drum pedal. We also analyzed movement data of pendulum wiggling at the wrist and the whole-body, which are the basis of such local and global movements including drum-set playing. The results suggest that the global coordination structure is involved in the accomplishment of the local pendulum task.

In animal experiments, we have revealed that perinatal exposure to dioxin causes social behavioral abnormality, accompanied with brain activity abnormalities in social stress situation. In this research, we succeeded in developing and practicing the analysis index of new mouse social behaviors focusing on social stress, as well as its data analysis algorithm, using the image analysis system.

     View Summary

    Optic flow generated by skilled/unskilled automobile driver (, that could be viewed by passengers in the car,) was recorded and re-presented to participants in the experiment. The result showed that the optic flow generated by the skilled driver would have the effects as follows: guiding the observer’s eye gaze to the distal point on the road, and to the inner distal point beyond the curve. Besides, the results of other experiments showed that lateral optic flow might induce anterior-posterior sway movement of observer’s head, and texts (number symbols) included in optic flow would inhibit the movement of observer’s head.

     View Summary

    This research aims at understanding from the viewpoint of the ecological phenomenology all human activity as circulative interactions between body-subject and the environment and trying to establish philosophical and theoretical ground for a comprehensive human environmental science. We have focused on the issue of how to construct a middle-scale human environment that is suitable for human wellbeing and environmental sustainability. During our 5 years research, we have achieved many splendid results, for examples a series of anthology, papers, presentations, symposiums, workshops, and invited lectures, as shown in “study results” and largely contributed to the formation of a new field of positivistic phenomenology of the environment.

     View Summary

    The purpose of our research was, in the light of an ecological approach, to investigate musicians’ bodily skills and their coordinative body structure that acts as a foundation of “dexterity” in musical performance. First, in order to record the features of body movement, we designed an experiment with a professional violinist and asked her to play musical fragments before and after receiving ecological-physical therapy. We found differences in the sensor data and also in the therapist’s diagnosis after the treatment. This implied that, through the therapy, the violinist’s muscle tension was reduced and some coordinative structures between body segments emerged and/or were re-activated, which increased flexibility and allowed the violinist to improve her performance. Additionally, we attempted to describe the continuity between experts’ bodily skills and young infants’ musical activities with reference to studies on the development of children’s physical and musical abilities.

    The effect of the act of wiggling one's body on posture control was studied. The change of strategy for posture control after the therapeutic wiggling movement (wiggling one's body by a physical therapist, or by oneself) was compared with the strategy after an ordinal strength training for outer muscles in terms of the sway in quiet standing. The results showed that the wiggling movement seemed to facilitate one's perception to his/her body by dynamic touch, and change the posture control strategy from static to dynamic.

     View Summary

    Psycholinguistic research on speech and spontaneous gesture has revealed that spontaneous gesture makes important contributions to the production and comprehension of instructions and narratives (e.g., story retelling). However, speech-gesture coordination is not necesarily stable all the time, but it can sometimes be disfluent. Possible factors contributing to the disfluency include speech tempo, complexity of the content of speech, honorifix, complexity due to the adjustment made for the addressee's comprehension level about the contents, etc. There does not seem to be systematic study about how spontaneous gesture and speech become disfluent and how they are organized to become fluent again. The present study focuses on what is called "microslips" in research on intrumental actions, and attempts to determine whether microslips can be observed with gesture, and, if so, what the conditions are to induce microslips in gesture. For this purpose, we collected cartoon narrative data of speakers relating the story of "Canary Row," where factors such as listener location was manipulated. The results suggest the effect of listener location and complexity of the speech content on average frequency of microslips on spontaneous gesture. These outcomes are to be described in papers in preparation for submitting as journal papers as well as presentations to be made in academic conferences.

    Media literacy has got it position in education in Japan. Among the reading and writing, there are many practices to watch and to recognize TV programs. However, there are few actions to the picture production.
    We have to show the models of the picture to activate picture production in Japanese school. Because, school teacher try to make work as broadcast level then practice do not continue. It is not understood that there is the development of picture production in the same way as the painting of the child, so child may make original work. In Japan, there is the culture that citizens enjoy the development of the child. We exhibit pictures and the handwritings of the child even though it's not so good works. We should make same culture.
    In this study, we cleared as follows:
    1. We made the system which children and students produce picture works in cooperation with elementary, junior high and high school teachers. We broadcast the works in Fukui pref. in cooperation with NHK Fukui Broadcasting, Station. 135 schools broadcasted their productions. It is a one-third of the total number of schools in Fukui pref. We showed that school had power to make a picture.
    2. We made the system to broadcast picture works made by university students in cooperation with NHK Mito Broadcasting Station. In the case of university, there are three purposes in picture production. 1st. We perform it media literacy education. We teach students how to make picture works and they are requested to make picture works as research report. 2nd. We promote it as the student's operant activity, assertion or expression of themselves. 3rd. We promote it as the introduction of our study and education activity. We broadcasted 32 programs in 3 years. We introduced research institute and student's circles in live for 18 times. We have broadcasted Total 50 times.
    Conclusion: We showed that we have a power to make picture works from elementary school to University. And also, we showed we can make so many products. We made a model of cooperation between School and Broadcasting Station which would be possible in the other areas and promote picture works.

    道具使用場面における課題の難易度と全身の協応状態との関係を明らかにするために、実験参加者の課題遂行時における「測定圧力中心分布」を、重心動揺計(ひずみゲージ式変換器:LUB-5OKB-P 4台、計装用コンディショナ:WGA-67OB-O 4台から構成)によって測定した。実験参加者の課題は「ハサミ(全長165mm,刃渡り75mm)の開閉運動」とし、ハサミの開閉運動(ヒンジ部における角度変化)を村田製作所製トリマポテンショメータ(PVS1A)によって計測した。大学生(すべて右利き)を被験者とし、楽な呼吸を行いながらもっとも好ましい速度で、しかし実際には紙を切らずに空中でハサミを開閉する条件(A条件)、および、楽な呼吸を行いながらもっとも好ましい速度で、A4版上質コピー用紙の長辺の縁を「およそ1cmの深さで、できるだけ細かく、ほぼ一定の間隔で短冊状に切り込むこと」を繰り返す条件(B条件)とに分けて実験を行った。重心動揺計から得られた波形データ(30秒間分)について、再帰性定量化分析(Recurrence Quantification Analysis)における3つの指標(%REC,%DET,MAXLINE)によって評価した。その結果、特に「%DET値」において、A条件<B条件となることがあきらかとなった。この結果は、ハサミを単に空中で開閉しているときとよりも、ハサミを使って紙を切るという注意を要する課題を遂行しているときに、全身の協調状態に関して、より決定論性の強い状態が構築されていることを示している.呼吸運動は重心の変動に影響を与える要因の一つであるが、呼吸運動を含む全身の協調状態は、道具使用場面において、課題に即して目的的に変化することが示唆された.

    本研究は、発話と身振りというマルチモーダルな身体運動の個人内及び個人間で成立する協調を生態心理学と心理言語学の観点から明らかにし、特に発話・身振り双方の下位系である呼吸運動との協調に着目して、発話と身振りの協調を生態力学的・心理言語学的に制約する情報を特定することを目的として行われた。今年度は以下の2つの研究を行った。
    (1)昨年度までに、母音の発声と手首の伸展・屈曲運動を同期させる協調実験を、個人内協調と個人間協調に関してそれぞれ実施した。その結果、発声と手首運動とのあいだの協調ダイナミクスの質的な転換と、呼吸運動のパターンの質的な転換とが密接に関わっていることを示した。これを踏まえて、今年度は、手首運動と呼吸運動の協調に関して、再帰定量分析(RQA)という手法を用いて直接評価した。その結果、個人内、個人間協調とも、協調モードの違いによって、カップリングの強さに違いがあることなどが明らかになりつつある。
    (2)「まく(巻く)」を連続して何度も発声すると、ある時点で「くま(熊)」に意味が反転したように感じられる、いわゆる意味反転という現象がある。この反転現象が課題開始から生起するまでにかかる時間は、意味的に関連する身振り(例では巻く動作)を共起させることで、遅延されることが知られている。本実験では、これが身振りのイメージによるものか、またはダイナミカルな情報によるものかを吟味することを目的として実験を実施したが、先行研究の結果とは異なり、身振り動作の種類が意味反転のタイミングには影響せず、動作の周波数のみが影響するという結果が得られた。この結果が示唆するところについては現在考察を進めているところである。
    この他、自然会話そのものに関する研究についても一定の成果が得られた。これらの成果の一部はすでに公表済みであるが、現在、公表していないものにっいて論文執筆作業を進めているところである。

    自己の身体の方向を知覚する際の、身体部位の慣性主軸の効果について確認するための実験を行った。被験者は椅子に腰掛け、前腕に十字型の機材(前後約63cm、左右約60cm、質量約675g。アルミと樹脂製)を固定された。機材の左右に突き出た腕には、「右に200g」「左に200g」「左右に100gずつ」のいずれかの条件で重りが取り付けられた。被験者は上腕を体側に密着させ、前腕を床と平行に保つように教示された。被験者の前腕部は、高さ80cmの位置に床と平行に設置されたパネル(幅120cm、奥行48cm)で上部から覆い隠された。パネル上部の被験者に相対する位置に、横一列(10cm間隔)に並んだ目標が取り付けられ、被験者は各試行においてそのうちの1つを、前腕の水平方向の向きを調整することによって指示するように求められた。以上の実験から、被験者の前腕による方向指示は、(1)重りの位置の条件によって体系的な誤差が生じる、(2)その誤差は、十字型の機材を含めた前腕部の慣性主軸の方向と一致していることが確認された。これにより、身体方向の知覚が当該部位の慣性主軸の知覚に基づいていることが確認された。しかし、一方で(3)指示すべき目標の位置による効果があることも確認された。その原因の一つとして、肘関節の内旋/外旋にともなう筋群のバランスの変化が考えられる。そこであらかじめ被験者の前腕部に一定の負荷を加えることにより、内旋/外旋のための筋群の一部を疲労させ、そのバランスを崩した上で同様の実験を行った。その結果、とりわけ前腕部の回外運動に関わる筋群を疲労させた際に、慣性主軸の方向に関する感受性が低下することが確認された。以上の結果から、自己の身体の方向に関する触覚的な印象を支える慣性主軸の知覚が、筋群のダイナミックなバランスによって支えられていることが示唆された。

  • 能動触による弾性体の触知覚

    1997  

     View Summary

    [手続き] つり下げられた弾性体(ひも。ケプラー製)の長さの知覚とその際に行われる能動的な探索運動との関係を明らかにするために以下の実験を行った。 金属製の支柱からつり下げられた4種類の長さのひも(0.6 m、0.8 m、1.0m、1.2m)を、その下端を手で持ち下方に引いてひもを振動させることで非視覚的に被験者(8名)にひもの長さを特定させた。ひもの上端には張力センサーを取り付け、ひもに力を加えられた時間を測定した。それらのデータをA/D変換器経由でコンピュータに取り込み、「ひも-手」系のダイナミクスを解析、特定した。[結果] 分析の結果、手で引かれた後に減衰するひものダイナミクスは以下の式で表されると考えられる。  It = a log e X + b (1) (Itはひもを引く個々の動作の間隔、Xはひもの長さ、aとbは定数) 8名のうち5名の被験者で、ひものダイナミクスに同調した運動(式(1)に良く当てはまる運動)を行った。つまり、短いひもでは短い時間間隔でひもに打撃を加え、長いひもでは短いひもよりも長い減衰までの時間を待って次の打撃を与えており、それがlogの関係にあった。また、これらの5名の被験者は、ひもの長さ(ひも上端の固定点までの距離)の知覚における成績もすぐれていた。一方、ひものダイナミクスに同調した運動を行わなかった3人の被験者では、ひもの長さの知覚における成績が他の5人と比較して良くなかった。[まとめ] (i)対象を知覚するための探索運動は、対象のダイナミクス(より正確に言えば、対象とそれに対して運動を仕掛ける知覚者の身体の構成するシステムのダイナミクス)によって制約されており、知覚者の探索運動は実際にそのダイナミクスに同調することができる (ii)対象(と身体)のダイナミクスに対して探索運動が同調できなければ、対象の知覚が困難である。研究成果の発表(予定も含む)三嶋博之。 (Sep. 17、 1997). 能動的触活動によるひもの長さの知覚(2)。ポスター発表、 日本心理学会第61回大会、 関西学院大学。
