  • Direct Comparisons of Upper-Limb Motor Learning Performance Among Three Types of Haptic Guidance With Non-Assisted Condition in Spiral Drawing Task.

    IEEE transactions on neural systems and rehabilitation engineering : a publication of the IEEE Engineering in Medicine and Biology Society   32   2545 - 2552  2024  [International journal]

    　View Summary

    In robot-assisted rehabilitation, it is unclear which type of haptic guidance is effective for regaining motor function because of the lack of direct comparisons among multiple types of haptic guidance. The objective of this study was to investigate the effects of different types of haptic guidance on upper limb motor learning in a spiral drawing task. Healthy young participants performed two experiments in which they practiced the drawing movement using a robotic manipulandum with a virtual wall (Path guidance), running direction pushing and virtual wall (Path & Push guidance), restriction to the target movement (Target guidance), or without haptic guidance (Free guidance). Experiment 1 compared the learning effects of the four types of guidance. Experiment 2 investigated the effects of pre-learning with Path, Path & Push, or Target guidance on post-learning with Free guidance. In Experiment 1, Free guidance demonstrated the greatest learning effect, followed by Path guidance, which showed a significantly greater improvement in task performance than the other two types of guidance. In Experiment 2, the type of pre-learning did not influence post-learning with Free guidance. The results suggested that learning with Path guidance showed a slightly slower but comparable effect to Free guidance and was the most effective among the three types of haptic guidance. The superiority of Path guidance over other haptic guidance was interpreted within the framework of error-based learning, in which the intensity of sensory feedback and voluntary motor control play important roles.

  • Visual feedback of finger writing in a patient with sensory aphasia: a case report and theoretical considerations.

    Neurocase   27 ( 1 ) 1 - 6  2020.12  [International journal]

    　View Summary

    Through cognitive task performance, we examined the functional role of finger writing (kūsho) in a Japanese patient with moderate sensory aphasia and reading difficulties. We hypothesized that the visual feedback of kūsho would improve visual language processing, which we tested with a "kanji construction task" using character subparts. Results showed a higher number of correct responses 1) when the patient used kūsho and 2) when visual feedback of finger movements was available. The results suggest that kūsho may not improve the retrieval of phonological information but does aid the visual processing necessary to assemble character subparts.

    本研究では，なぜヒトが意図しない行為をおこなってしまうのかを明らかにするため，実験的に誘発可能な「書字スリップ」とよばれる現象を通してアクション・スリップの生起メカニズムを運動計算論的に解明することを目的とする。2022年度には，初年度に構築した書字動作解析システムの修正・改善を進めたことに加え（課題1），同システムを用いて健常若年者における書き間違い生起メカニズムを検討した（課題2）。
    【課題1：マーカーレス動作追跡システムを用いた深層学習による書字動作解析基盤の確立】
    健常若年者を対象に実施した行動実験を通して，動画データから書字運動を運動学的に解析するプログラム（初年度に作成）の修正・改良をおこなった。実験では，書字スリップを誘発するための急速反復書字課題を実施し，書字中のペンスタイラスの位置データから効果器先端の最適運動特徴点を抽出した。
    【課題2：状態空間モデルに基づく書き間違いの健常モデルの構築】
    書字の運動学的要素と感覚情報入力が書字スリップの生起に与える影響を解明するため，健常若年者を対象に急速反復書字課題を実施した。実験では被験者間条件として視聴覚フィードバックを操作し，書字中の上肢および書字軌道が見える群と見えない群，および書字中に生じる効果器と書字面との摩擦音が聴こえる群と聴こえない群を設定した。得られたデータについて，書字スリップ生起前後の運動学的指標の変化に着目しデータ解析をおこなった。

    　View Summary

    The project obtained two major findings. First, we clarified that voluntary motor action using a body part is executed not to get kinematic feedback but rather to create visual feedbacks of the action for cognitive facilitation. Second, we indicated that the speed-accuracy tradeoff does not exist in learning processes and that the two factors may be independently controlled in human motor system. These findings would help improve motor retaliation for patients with Apraxia and Alexia especially in terms of its theoretical backing.

    　View Summary

    The present study aimed to reveal the underlying mechanism how bodily movements influence cognitive processing of written language by using young and elderly healthy individuals and brain damaged patients. The series of experiments consistently showed that kusho behavior positively affected cognitive task performance (Kanji construction task) only when the visual feedback of the finger movements was available. In addition, we showed a positive correlation between the task performance and vocabulary score only in the condition that target stimuli were presented for 3 seconds. Further, we confirmed that the facilitation effects of kusho behavior for the elderly individuals and a patient with a parietal lobe lesion. These results together supported the hypothesis that the visual aspects of kusho behavior assist cognitive processing regardless of the general cognitive ability.

    　View Summary

    The present study aimed to improve the understanding of the acquired neurological disorder called agraphia (can read but cannot write characters), and to invent a new clinical assessment for the disorder. We had two achievements. First, we provided new quantitative measures which can reflect the symptoms of agraphia patients more accurately and intuitively in terms of motor control theory. Second, using those measures, we made a software application which can easily assess writing disorders in clinical circumstances.

  • Constraints and strategies in tool-use grasping

    Itaguchi Yoshihiro, Yamada Chiharu, Fukuzawa Kazuyoshi

    Proceedings of the Japanese Society for Cognitive Psychology   2015 ( 0 ) 16 - 16  2015

    　View Summary

    The present study investigated how much the strategic factor contributes to the differences between the hand-use and the tool-use grasping in motor control. We predicted that even reach-to-grasp movements with a novel tool would show the hand-like aperture profile when the strategic factors were excluded. To test this idea, we employed fast movements to grasp a target, where participants were instructed not to care if they failed to grasp the target object. The results showed that the kinematic profiles of the grasping movements with using the novel tool became similar to that of hand-use grasping as the velocity increased. The present study implies that the shared computation principle is used for motor planning in both hand-use and tool-use grasping, and that the awkwardness-dependent strategy may be driven to prevent the target object from dropping off from the tips of the effectors.

  • Kinematic Components of Experimentally Induced Slips of the Pen

    YAMADA CHIHARU, Itaguchi Yoshihiro, Fukuzawa Kazuyoshi

    Proceedings of the Japanese Society for Cognitive Psychology   2014 ( 0 ) 2 - 2  2014

    　View Summary

    When people write the same kana character repeatedly as fast as possible, they sometimes mistakenly write other characters that they do not intend to write. This type of error is known as a writing slip (Nihei, 1984; 1990). Previous studies reported certain characters induce writing slips. The present study investigated the relationship between target characters and mistaken characters in terms of the kinematic and visual similarity. As a measure of the kinematic similarity, we used the similarity in trajectory and velocity. We defined visual similarity based on the questionnaire responses. In the experiment, participants most frequently slipped to write 'o' when they intended to write 'a'. Their visual similarity was very high, whereas the kinematic similarity was low. The result suggests the visual similarity affects the occurrence of writing slips to a much greater extent than the kinematic similarity.
