  • 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.

  • Intentional coordination of breathing and limb movement from the perspective of the dynamical systems approach

    TAKASE Hiroki, MISHIMA Hiroyuki, HARUKI Yutaka

    NINCHISHINRIGAKUKENKYU   1 ( 1 ) 63 - 73  2004.05  [Refereed]

     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.

    [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。
