  • Olfactory Cues to Reduce Retrograde Interference During the Simultaneous Learning of Conflicting Motor Tasks

    Eiko Matsuda, Daichi Misawa, Shiro Yano, Toshiyuki Kondo

    Journal of Robotics and Mechatronics   34 ( 4 ) 746 - 755  2022.08  [Refereed]

     View Summary

    We investigated the ability of humans to adapt to a novel environment by kinematic transformation. This adaptation was studied via behavioural experiments using a robotic manipulandum – a system designed to arbitrarily generate virtual force fields against a human hand and subsequently record the hand’s trajectory. By repeating motor tasks, this study’s participants gradually learned to move correctly under a newly experienced force field, such as rotating in a clockwise direction. However, each participant’s motor memory was destroyed if he/she experienced an opposing force field (e.g., in a counterclockwise direction) immediately after learning the initial movement, which is known as retrograde interference. In some previous studies, it has been considered that by presenting sensory cues to highlight the difference in two opposing force fields, participants can learn both force fields independently without interference. In this study, we investigated the functionality of olfactory cues – specifically lemon and lavender odors – in reducing retrograde interference. Forty-five university students participated in an experiment using a robotic manipulandum. Our results have shown that the presence of lemon odor reduces the destruction of motor memory, while that of lavender did not, suggesting that odors can enhance simultaneous motor learning but the effect depends on the type of odor used.

  • Time Series Analyses of the Responses to Sensory Stimuli of Children with Severe and Multiple Disabilities

    Eiko Matsuda, Tatsuki Takenaga, Mamoru Iwabuchi, Kenryu Nakamura

    Journal of Robotics and Mechatronics   34 ( 4 ) 726 - 738  2022.08  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    Severe and multiple disabilities (SMD) refers to the simultaneous occurrence of intellectual and physical problems. SMD in children is difficult to assess, as they often do not have the proper language or bodily responses to represent their feelings. In this study, we propose a methodology for evaluating reactions of children with SMD to sensory stimuli that does not rely on observations by humans, but rather is based on automatic detection of video-recorded data and quantification by time-series analyses. We present two case studies with typical participants: one with large body movements (P1) and another with subtle body movements (P2). For P1, it was observed that he showed larger bodily movements just before the onset of tactile stimuli, while he became silent for approximately 10 s after the onset, with the stimuli causing him to reduce self-stimulatory behavior and pay attention to his external environment. For P2, two quantitative methodologies – correlation coefficient and Granger causality – were adopted, to compare behavioral difference during the presentation of either sour or sweet taste stimuli. For the sweet conditions, the movement of the mouth was considered to be generated by some internal causes. Through these experiments, we confirmed the authenticity of assessments made by the participants’ caregivers, and also revealed otherwise unseen behavioral patterns and structures.

  • Developmental Changes in Number Personification by Elementary School Children

    Frontiers in Psychology   9   2214 - 2214  2018  [Refereed]  [International journal]

     View Summary

    Children often personify non-living objects, such as puppets and stars. This attribution is considered a healthy phenomenon, which can simulate social exchange and enhance children's understanding of social relationships. In this study, we considered that the tendency of children to engage in personification could potentially be observed in abstract entities, such as numbers. We hypothesized that children tend to attribute personalities to numbers, which diminishes during the course of development. By consulting the methodology to measure ordinal linguistic personification (OLP), which is a type of synesthesia, we quantified the frequency with which child and adult populations engage in number personification. Questionnaires were completed by 151 non-synesthetic children (9-12 years old) and 55 non-synesthetic adults. Children showed a higher tendency than adults to engage in number personification, with respect to temporal consistency and the frequency of choosing meaningful answers. Additionally, children tended to assign unique and exclusive descriptions to each number from zero to nine. By synthesizing the series of analyses, we revealed the process in which number personification diminishes throughout development. In the discussion, we examined the possibility that number personification serves as a discrimination clue to aid children's comprehension of the relationships between numbers.

  • Olfactory Cues to Enhance Simultaneous Motor Leaning in Opposing Force Fields

    Eiko Matsuda, Daichi Misawa, Shiro Yano, Kondo Toshiyuki

    2017 IEEE International Symposium on Micro-Nano Mechatronics and Human Science (MHS2017)   2018-January   267 - 269  2017  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    Simultaneous learning of two contradicting motor tasks (i.e. tasks with opposing force fields) has been reported to be difficult. Osu et al. (2004) [11] revealed that such dual learning is achieved by attributing different contextual cues to each motor task (e.g. displaying a red color during motor task A and a blue color during moto task B). Based on this previous study, we aimed to study whether olfactory stimuli can serve as contextual cues. We conducted behavioral experiments in which the participants were required to learn arm-reaching tasks in unfamiliar force fields. As contextual cues, we used odors of lemon and lavender, which have opposing functions: Lemon is believed to enhance mental or physical task performance, while lavender is considered to be a relaxant. Our results showed that lemon odors reduced the number of errors after learning contradicting motor tasks, while lavender did not. This suggests that specific olfactory cues can serve as contextual cues to promote the simultaneous learning of contradicting motor tasks.

  • A Robotic Approach to Understanding the Role and the Mechanism of Vicarious Trial-And-Error in a T-Maze Task

    Eiko Matsuda, Julien Hubert, Takashi Ikegami

    PLOS ONE   9 ( 7 ) e102708:1 - 19  2014.07  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    Vicarious trial-and-error (VTE) is a behavior observed in rat experiments that seems to suggest self-conflict. This behavior is seen mainly when the rats are uncertain about making a decision. The presence of VTE is regarded as an indicator of a deliberative decision-making process, that is, searching, predicting, and evaluating outcomes. This process is slower than automated decision-making processes, such as reflex or habituation, but it allows for flexible and ongoing control of behavior. In this study, we propose for the first time a robotic model of VTE to see if VTE can emerge just from a body-environment interaction and to show the underlying mechanism responsible for the observation of VTE and the advantages provided by it. We tried several robots with different parameters, and we have found that they showed three different types of VTE: high numbers of VTE at the beginning of learning, decreasing numbers afterward (similar VTE pattern to experiments with rats), low during the whole learning period, and high numbers all the time. Therefore, we were able to reproduce the phenomenon of VTE in a model robot using only a simple dynamical neural network with Hebbian learning, which suggests that VTE is an emergent property of a plastic and embodied neural network. From a comparison of the three types of VTE, we demonstrated that 1) VTE is associated with chaotic activity of neurons in our model and 2) VTE-showing robots were robust to environmental perturbations. We suggest that the instability of neuronal activity found in VTE allows ongoing learning to rebuild its strategy continuously, which creates robust behavior. Based on these results, we suggest that VTE is caused by a similar mechanism in biology and leads to robust decision making in an analogous way.

     View Summary

    Spontaneous development of neuronal cells was recorded around 4-34 days in vitro (DIV) with high-density CMOS array, which enables detailed study of the spatio-temporal activity of neuronal culture. We used the CMOS array to characterize the evolution of the inter-spike interval (ISI) distribution from putative single neurons, and estimate the network structure based on transfer entropy analysis, where each node corresponds to a single neuron. We observed that the ISI distributions gradually obeyed the power law with maturation of the network. The amount of information transferred between neurons increased at the early stage of development, but decreased as the network matured. These results suggest that both ISI and transfer entropy were very useful for characterizing the dynamic development of cultured neural cells over a few weeks. © 2013 IEEE.

    共感覚とは、1種類の刺激入力に対して、複数の感覚や認知が同時に感じられる現象である。例えば「アルファベットのaを見ると赤く感じる」などが挙げられる。共感覚は人口の1%に見られることがわかっているが、一方で、一般的な成人にも「共感覚的傾向」と呼ばれる、共感覚に似た色字対応が見られることがわかっている。文字や数字などに対して色などのイメージを付与することで、具体的に捉えることが可能となり、理解が促進されるという、共感覚的傾向の機能的側面が示唆されている。本研究課題では、広く一般に見られる共感覚的傾向に焦点を絞り、学習との関連を示すことである。具体的には、以下の実験1, 実験2の2段階に分けて検討している。
    <BR>
    実験1として計画していた、「漢字の読み替えによる共感覚的傾向の発達的変化」については、小学生を対象に、漢字と色との対応関係を調べるためのものである。実際に、小学3-6年生184名を対象に調査紙による調査を行った。また、追加実験として成人200名を対象にした調査を行った。その結果、小学生にも成人にも、漢字の色字対応が広く見られたが、年齢による変化は見られなかった。これは成人に見られる色字対応が、小学3年生の時点で形成されていることを示している。以上の結果を現在論文にまとめているところである。
    <BR>
    実験2として計画していた、「数学者に見られる共感覚的傾向」については、予備調査として位置づけられるウェブアンケートを実施し、今年度は大規模な調査紙調査を実施する予定である。これにより、数字や数学的概念に対する共感覚的な印象が、数学の理解にどのように影響しているのかを明らかにすることが期待される。

    1.小学生に見られる数字の擬人化傾向と発達的変化
    子どもは一般的に、ぬいぐるみや家具など様々なものを擬人化することが知られている。これまで研究されてきた子どもの擬人化傾向は、具体的な事物に関するものであり、例えば数字・月日・文字などの抽象的な事物に対しても、起こりうるのかは明らかにされてこなかった。本研究では、特に数字の擬人化に着目し、子どもは抽象的な事物に対しても擬人化を行い、それが具象物に対する擬人化傾向と同様、大人になるにつれて消失するとの仮説を立て、これを検証した。小学4年生, 6年生, 成人を対象に調査紙調査を行ったところ、1) 擬人的表現を割り当てた頻度、2) 回答の一貫性、3) 回答の多様性の3つの観点から、小学4年生には強い擬人化傾向が見られたが、年齢が上がるほど傾向が弱まることが示された。この結果に基づき、擬人的傾向と抽象的な事物の学習との関連性を議論した。また、成人に見られる共感覚的傾向との類似性から、共感覚的傾向の発達的側面について考察を行った。本成果は、2018年にポーランドで行われた国際会議ASSC22 にて、また、国際的な学術誌であるFrontiers in Psychology にて発表した。

    2.ロボットマニピュランダムを用いた、能動的な色選択による逆行性干渉の軽減
    手先の運動学習において、2つの相反する運動は干渉し合うため、同時に学習することが困難であると言われてきたが、2つの運動を弁別するための感覚刺激 (色, 音など) を運動と同時に提示することで、干渉を軽減できる可能性が論じられてきた。本研究では、被験者がその運動に似合うと感じる感覚刺激であれば、干渉の軽減に効果があるとの仮設を立て、これを検証した。その結果を2018年度日本心理学会全国大会にて発表した。
