      The sense of agency, which refers to the subjective feeling of control, is an essential aspect of self-consciousness. We argue that distinguishing between the sensitivity and criterion of this feeling is important for discussing individual differences in the sense of agency and its connections with other cognitive functions.

      PURPOSE: An internal model deficit is considered to underlie developmental coordination disorder (DCD); thus, children with DCD have an altered sense of agency (SoA), which is associated with depressive symptoms. Furthermore, the perception of action-outcome regularity is present in early development, is involved in the generation of SoA, and has roles in adaptive motor learning and coordinated motor skills. However, perceptual sensitivity to action-outcome regularity has not been examined in children with DCD. METHODS: We investigated perceptual sensitivity to action-outcome regularity in 6-15-year-old children with DCD and age- and sex-matched typically developing (TD) children. Both groups were assessed for coordinated motor skills with the Movement Assessment Battery for Children-2nd Edition, while the DCD group was assessed with the DCD Questionnaire, Social Communication Questionnaire, Attention-Deficit/Hyperactivity Disorder-Rating Scale, and Depression Self- Rating Scale for Children. RESULTS: Perceptual sensitivity to action-outcome regularity was significantly reduced in children with DCD. However, there was a significant correlation between perceptual sensitivity to action-outcome regularity and age in DCD and TD children. Perceptual sensitivity to action-outcome regularity was significantly lower in younger children with DCD than in younger and older TD children, but there were no significant differences between older children with DCD and younger and older TD children. CONCLUSION: The current results suggest that children with DCD have significantly reduced perceptual sensitivity to action-outcome regularity at younger ages, which may alter SoA and inhibit internal model development, thereby reducing motor skill coordination.

      Neuromodulation techniques for modulating brain activity can affect performance in a variety of behaviors. Techniques including transcranial alternating current stimulation and random noise stimulation can modulate neural oscillations. However, the intervention effect of neuromodulation approaches on motor learning is poor, partly because the electroencephalography (EEG) power spectra associated with the motor learning process has not yet been fully elucidated. Therefore, we investigated the characteristics of EEG power spectra in the process of motor learning in 15 right-handed healthy participants (5 females; mean age = 22.8 ± 3.0 years). The motor task was a ball-rotation task in which participants rotated two balls in the palm of their left hand. Participants performed a pre-test, the motor learning tasks, and a post-test. In the motor learning tasks, twenty 60 s trials were performed in the clockwise (CW) direction. Before and after the motor learning tasks, CW and counterclockwise (CCW; control condition) tasks were performed for 60 s each as pre- and post-tests. Therefore, CW direction was set as a motor learning task, while CCW was a test-only control task. EEG was recorded during the tests and tasks, and the power spectra in the alpha, beta, and gamma oscillations were calculated and compared between pre- and post-tests. The results showed that in the CW post-test, the power of the gamma band in the left parietal areas and the right frontal area was significantly higher than in the pre-test. In the CCW, there was no significant difference in each band at each area between the pre- and post-tests. Our findings reveal the characteristics of the EEG spectra related to the motor learning process. These results may help to establish more effective neuromodulation approaches to modifying neural oscillations in motor learning, including in rehabilitation fields.

      Sense of agency (SoA) refers to the subjective feeling of controlling one's own actions and sensory feedback. The SoA occurs when the predicted feedback matches the actual sensory feedback and is responsible for maintaining behavioral comfort. However, sensorimotor deficits because of illness cause incongruence between prediction and feedback, so the patient loses comfort during actions. Discomfort with actions associated with incongruence may continue robustly (i.e., "not" adaptable) throughout life because of the aftereffects of the disease. However, it is unclear how the SoA modulates when incongruency is experienced, even for a short term. The purpose of this study was to investigate the adaptability of the SoA in healthy participants in sensorimotor tasks for a short term. Participants were divided into congruent and incongruent exposure groups. The experimental task of manipulating the ratio of the self-control of a PC cursor was used to measure the SoA before and after exposure to congruent or incongruent stimuli. The results showed no significant differences between the groups before and after exposure for a short term. The finding that the SoA was not adaptable may assist in guiding the direction of future studies on how to correct incongruence.

      Along with the comparator model, the perception of action-outcome regularity is involved in the generation of sense of agency. In addition, the perception of action-outcome regularity is related to motor performance. However, no studies have examined the developmental changes in the perception of action-outcome regularity. The current study measured perceptual sensitivity to action-outcome regularity and manual dexterity in 200 children aged between 5 and 16 years. The results showed that perceptual sensitivity to action-outcome regularity was significantly lower in 5-6-year-old children than in 9-16-year-old children, and that it was significantly lower in children with low manual dexterity than in children with medium to high manual dexterity. Correlation analyses revealed significant correlations of age and perceptual sensitivity to action-outcome regularity, but no significant correlation of manual dexterity and perceptual sensitivity to action-outcome regularity, either overall or in any age band. The present study suggests that perceptual sensitivity to action-outcome regularity is immature at 5-6 years of age and that it may be impaired in 5-16-year-old children with poor manual dexterity.

      Self-related stimuli are important cues for people to recognize themselves in the external world and hold a special status in our perceptual system. Self-voice plays an important role in daily social communication and is also a frequent input for self-identification. Although many studies have been conducted on the acoustic features of self-voice, no research has ever examined the spatial aspect, although the spatial perception of voice is important for humans. This study proposes a novel perspective for studying self-voice. We investigated people's distance perception of their own voice when the voice was heard from an external position. Participants heard their own voice from one of four speakers located either 90 or 180 cm from their sitting position, either immediately after uttering a short vowel (i.e., active session) or hearing the replay of their own pronunciation (i.e., replay session). They were then asked to indicate which speaker they heard the voice from. Their voices were either pitch-shifted by ± 4 semitones (i.e., other-voice condition) or unaltered (i.e., self-voice condition). The results of spatial judgment showed that self-voice from the closer speakers was misattributed to that from the speakers further away at a significantly higher proportion than other-voice. This phenomenon was also observed when the participants remained silent and heard prerecorded voices. Additional structural equation modeling using participants' schizotypal scores showed that the effect of self-voice on distance perception was significantly associated with the score of delusional thoughts (Peters Delusion Inventory) and distorted body image (Perceptual Aberration Scale) in the active speaking session but not in the replay session. The findings of this study provide important insights for understanding how people process self-related stimuli when there is a small distortion and how this may be linked to the risk of psychosis.

      <title>Abstract</title>The sense of agency refers to the feeling of control over one’s own actions, and through them, the external events. This study examined the effect of modified visual feedback on the sense of agency over one’s body movements using virtual reality in healthy individuals whose motor control was disturbed. Participants moved a virtual object using their right hand to trace a trajectory (Experiment 1) or a leading target (Experiment 2). Their motor control was disturbed by a delay in visual feedback (Experiment 1) or a 1-kg weight attached to their wrist (Experiment 2). In the offset conditions, the virtual object was presented at the median point between the desired position and the participants’ actual hand position. In both experiments, participants reported improved sense of agency in the offset condition compared to the aligned condition where the visual feedback reflected their actual body movements, despite their motion being less precise in the offset condition. The results show that sense of agency can be enhanced by modifying feedback to motor tasks according to the goal of the task, even when visual feedback is discrepant from the actual body movements. The present study sheds light on the possibility of artificially enhancing body agency to improve voluntary motor control.

    • Perception and control: individual difference in the sense of agency is associated with learnability in sensorimotor adaptation. 国際誌

      Adaptive motor learning refers to the ability to adjust to novel disturbances in the environment as a way of minimizing sensorimotor errors. It is known that such processes show large individual differences and are linked to multiple perceptual and cognitive processes. On the other hand, the sense of agency refers to the subjective feeling of control during voluntary motor control. Is the sense of agency just a by-product of the control outcome, or is it actually important for motor control and learning? To answer this question, this study takes an approach based on individual differences to investigate the relationship between the sense of agency and learnability in sensorimotor adaptation. Specifically, we use an adaptive motor learning task to measure individual differences in the efficiency of motor learning. Regarding the sense of agency, we measure the perceptual sensitivity of detecting an increase or a decrease in control when the actual level of control gradually increases or decreases, respectively. The results of structure equation modelling reveal a significant influence of perceptual sensitivity to increased control on motor learning efficiency. On the other hand, the link between perceptual sensitivity to decreased control and motor learning is nonsignificant. The results show that the sense of agency in detecting increased control is associated with the actual ability of sensorimotor adaptation: people who are more sensitive in detecting their control in the environment can also more quickly adjust their behaviors to novel disturbances to acquire better control, compared to people who have a less sensitive sense of agency. Finally, the results also reveal that the processes of increasing control and decreasing control may be partially independent.

      Driving assistance technology has gained traction in recent years and is becoming more widely used in vehicles. However, drivers usually experience a reduced sense of agency when driving assistance is active even though automated assistance improves driving performance by reducing human error and ensuring quick reactions. The present study examined whether driving assistance can maintain human sense of agency during early deceleration in the face of collision risk, compared with manual deceleration. In the experimental task, participants decelerate their vehicle in a driving simulator to avoid collision with a vehicle that suddenly cut in front of them and decelerated. In the assisted condition, the system performed deceleration 100 ms after the cut-in. Participants were instructed to decelerate their vehicle and follow the vehicle that cut-in. This design ensured that the deceleration assistance applied a similar control to the vehicle as the drivers intended to, only faster and smoother. Participants rated their sense of agency and their driving performance. The results showed that drivers maintained their sense of agency and improved driving performance under driving assistance. The findings provided insights into designing driving assistance that can maintain drivers' sense of agency while improving future driving performance. It is important to establish a mode of joint-control in which the system shares the intention of human drivers and provides improved execution of control.

      The self is a distinct entity from the rest of the world, and actions and sensory feedback are our channels of interaction with the external world. This study examined how the sense of control influences people's perception of sensorimotor input under the framework of categorical perception. Twenty human participants (18 males, two females) took part in both experiments. Experiment 1 showed that the sensitivity (d') of detecting a 20% change in control from no change was higher when the changes occurred at the control-category boundary than within each category. Experiment 2 showed that the control categories greatly affected early attention allocation, even when the judgment of control was unnecessary to the task. Taken together, these results showed that our perceptual and cognitive systems are highly sensitive to small changes in control that build up to a determinant change in the control category within a relatively narrow boundary zone between categories, compared to a continuous, gradual physical change in control.Significance Statement Categorical perception is an important cognitive function that connects human low-level perceptual systems with high-level conceptual systems. Categorical perception has been intensively studied with sensory features (e.g., color and faces), but little is known about sensorimotor information, despite its importance for interacting with the external world. This is the first study to show that individuals perceive their control in meaningful categories rather than via linear encoding. The categorical perception of control diminishes sensitivity to differences within control categories, while increasing sensitivity to sensorimotor inputs at the control-category boundaries. The findings broaden our understanding on how human action influences the perception of action consequences, and how humans organize the external world according to the consequences of their actions.

      In everyday life, people control objects in the world around them to varying degrees. The processes people actively use to establish their control, while interacting with an environment containing large ambiguity, remain unknown. This study examines how people explore their control over the environment and how they detect small differences in control among objects. In the experimental task, participants moved three dots on a screen and identified one dot over which the level of control is different from that of the other two. The results support a two-step behavior mechanism underlying the sensing of control difference: People first explore their overall control in the environment, and then the results of the initial exploration are used to selectively tune the direction (i.e., either more or less) of the detected control difference, ensuring efficient and rapid detection of the type of control difference that is potentially important for further action selections.

      <p>Improving the walking functions of hemiplegia patients after a stroke or brain injury is an important rehabilitation challenge. Recently, walking assist robots have been introduced in advanced rehabilitation facilities as a way to improve the efficiency of patient rehabilitation and restore their walking functions. Expert therapists can apply this device on different patients; however, such application mainly depends on the therapist's tacit knowledge. Thus, it is often harder for novice therapists to apply such devices on different types of patients. Consequently, effective use of a walking assist robot has become a new patient rehabilitation skill. Taking rehabilitation as a service provided by medical doctors or therapists to their patients, this study aims to improve the quality of the rehabilitation service. In particular, the objective of this study is to abstract the rehabilitation skill of expert therapists in using a walking assist robot by applying a service science methodology known as skill education. Skill abstraction was performed by interviewing an expert therapist. From this interview, it was found that the expert therapist classified hemiplegia patients into four different classes. Using videos of patients walking, further analysis revealed the expert's tacit knowledge, which was indicated by differences observed among these four groups in particular phases of the patients' walking patterns. This study shows that by successfully obtaining explicit knowledge of part of a rehabilitation skill by using a walking assist robot (which until now was a tacit knowledge of experts), and then organizing the acquired explicit knowledge, even non-experts can easily reproduce the skill of experts in new patient rehabilitation.</p>

      <p>Several disease presentations are linked to a mismatch between the real body and the body's internal representation of itself. In order to develop effective rehabilitation therapies, it is necessary to understand the mechanisms underlying changes in body representation. In this study, we focused on changes in body representation of the upper limb as a large part of the body and investigated the conditions under which such changes occur. Participants were presented four conditions which differentially affected their sense of ownership and agency, including a movement condition related to their sense of agency, and a visual hand information condition related to the sense of ownership. In the experiment, participants were asked to move their upper limb forward and backward on a manipulandum. Results of the study showed that visual hand position affected changes in body representation relevant to both conscious and unconscious body parts. In addition, changes in the representation of the unconscious body part occurred with, and were dependent on, active movement.</p>

      The sense of agency emerges when our voluntary actions produce anticipated or predictable outcomes in the external world. It remains unclear how the sense of control also influences our perception of the external world. The present study examined perceptual processing of self-generated motion versus non-self-generated motion using steady-state visual evoked potentials (SSVEPs). Participants continuously moved their finger on a touchpad to trigger the movements of two shapes (Experiment 1) or two groups of dots (Experiment 2) on a monitor. Degree of control was manipulated by varying the spatial relation between finger movement and stimulus trajectory across conditions. However, the velocity, onset time, and offset time of visual stimuli always corresponded to participants’ finger movement. Stimuli flickered at a frequency of either 7.5 Hz or 10 Hz, thus SSVEPs of these frequencies and their harmonics provided a frequency-tagged measurement of perceptual processing. Participants triggered the motion of all stimuli simultaneously, but had greater levels of control over some stimuli than over others. Their task was to detect a brief colour change on the border(s) of one shape (Experiment 1) or of one group of dots (Experiment 2). Although control over shapes/dots was irrelevant to the visual detection task, we found stronger SSVEPs for stimuli that were under a high level of control, compared with the stimuli that were under a low level of control. Our results suggest that the spatial regularity between self-generated movements and visual input boosted the neural responses underlying perceptual processing. Our results support the preactivation account of sensory attenuation, suggesting that perceptual processing of self-generated events is enhanced rather than inhibited.

      <p>Back pain has been a serious problem for novice nurses who care for bedridden patients. To avoid back pain, placing a slippery sliding sheet beneath a patient has been suggested so that nurses can pull it when repositioning the patient rather than lifting the patient. However, inappropriate use of the sheet may not reduce lumbar pain. Therefore, it is important to identify skills required for novice nurses to perform bed care movements using a sliding sheet. This study firstly performed interview to obtain useful knowledge from expert nurses who are skilled in using a sliding sheet. Next, a simulation study was then conducted to determine specific bed care movements that would minimize lumbar joint moment associated with lumbar pain. The simulated and expert movements were compared to validate whether expert movements decreases lumbar joint moment. Finally, a novice participant was taught these expert movements, and the educational effect of using these skills was validated. Our results showed that the experts used characteristic movements, keeping the upper arm and trunk stabilized and utilizing a shift in body weight, when performing bed care movements with the sliding sheet. Additionally, the expert movements and simulated movements were shown to be similar. This result confirmed that expert movements could contribute to reducing lumbar joint moments. Moreover, a novice participant could decrease lumbar moment using skills derived from effective education.</p>

      "Sense of control" refers to the subjective feeling of control over external events. Numerous neuropsychological studies have investigated the neural basis of the sense of control during action performance; however, most previous studies have focused on responses to a single discrete action outcome rather than real-time processing of action-outcome sequences. In the present study, we aimed to identify whether certain patterns of brain activation are associated with the perceived control during continuous movement. We recorded electroencephalography (EEG) signals while participants continuously moved a right-handed mouse in an attempt to control multiple visual stimuli. When participants perceived a sense of control over the stimuli, we observed a positive potential approximately 550 ms after the onset of movement, while no similar potential was observed when participants reported a lack of control. The appearance of this potential was consistent with the time window of awareness of control in a behavioral test using the same task, and likely reflected the explicit allocation of attention to control. Moreover, we found that the alpha-mu rhythm, which is linked to sensorimotor processing, was significantly suppressed after participants came to a conclusion regarding the level of control, regardless of whether control or lack of control was perceived. In summary, our results suggest that the late positive potential after the onset of the movement and the suppression of alpha-mu rhythm can be used as markers of the perception of control during continuous action performance and feedback monitoring.

      Sense of agency (SoA) refers to the feeling of controlling ones own actions, and the experience of controlling external events with ones actions. The present study examined the effect of strength of intentional effort on SoA. We manipulated the strength of intentional effort using three types of buttons that differed in the amount of force required to depress them. We used a self-attribution task as an explicit measure of SoA. The results indicate that strength of intentional effort enhanced self-attribution when action-effect congruency was unreliable. We concluded that intentional effort importantly affects the integration of multiple cues affecting explicit judgments of agency when the causal relationship action and effect was unreliable.

      Body representation refers to perception, memory, and cognition related to the body and is updated continuously by sensory input. The present study examined the influence of goals on body representation updating with two experiments of the rubber hand paradigm. In the experiments, participants moved their hidden left hands forward and backward either in response to instruction to touch a virtual object or without any specific goal, while a virtual left hand was presented 250 mm above the real hand and moved in synchrony with the real hand. Participants then provided information concerning the perceived heights of their real left hands and rated their sense of agency and ownership of the virtual hand. Results of Experiment 1 showed that when participants moved their hands with the goal of touching a virtual object and received feedback indicating goal attainment, the perceived positions of their real hands shifted more toward that of the virtual hand relative to that in the condition without a goal, indicating that their body representations underwent greater modification. Furthermore, results of Experiment 2 showed that the effect of goal directed movement occurred in the active condition, in which participants moved their own hands, but did not occur in the passive condition, in which participants' hands were moved by the experimenter. Therefore, we concluded that the sense of agency probably contributed to the updating of body representation involving goal directed movement.

      In many sports, essential skills exist in terms of muscle activation in order to improve performance. However, it is difficult to identify the important muscle activation, and moreover novices cannot observe and imitate it since muscle activation is hardly visible. This study especially focuses on human rowing motion to extract an important skill in terms of muscle activation and we develop skill education system for novices to learn the skill. Firstly, strength and activation timing of lower leg muscle are evaluated to detect the expert skill based on their peak value and cross correlation during movement. Next, new skill education system is suggested by simultaneous presentation of real human movement and muscle activations of the targeted muscle. In the proposed system, muscle color is continuously changed based on its activation level for novices to perceive their muscle activation visually. Both experts and novices participated at our skill extraction experiment to compare their muscle activation. Results showed that experts had larger peak activation level and different profile in rectus femoris muscle. Therefore, our skill education system focused on rectus femoris muscle to present its activation level and movement simultaneously. In order to evaluate efficacy of the developed system, four different education instructions were conducted to novices; linguistic education, simultaneous presentation of motion and muscle activation of the expert, off-line presentation of novices motion and muscle activation, and real time presentation of novices motion and muscle activation. Performance of novices was evaluated after each instruction based on peak activation level, cross correlation, and exerted power on the rowing ergometer. These performance change after each education implied providing integrated view of novices motion and muscle activation in real-time could improve performance of rowing motion.

      Sense of agency refers to the subjective feeling of controlling events through one's behavior or will. Sense of agency results from matching predictions of one's own actions with actual feedback regarding the action. Furthermore, when an action involves a cued goal, performance-based inference contributes to sense of agency. That is, if people achieve their goal, they would believe themselves to be in control. Previous studies have shown that both action-effect comparison and performance-based inference contribute to sense of agency; however, the dominance of one process over the other may shift based on task conditions such as the presence or absence of specific goals. In this study, we examined the influence of divided attention on these two processes underlying sense of agency in two conditions. In the experimental task, participants continuously controlled a moving dot for 10 s while maintaining a string of three or seven digits in working memory. We found that when there was no cued goal (no-cued-goal condition), sense of agency was impaired by high cognitive load. Contrastingly, when participants controlled the dot based on a cued goal (cued-goal-directed condition), their sense of agency was lower than in the no-cued-goal condition and was not affected by cognitive load. The results suggest that the action-effect comparison process underlying sense of agency requires attention. On the other hand, the weaker influence of divided attention in the cued-goal-directed condition could be attributed to the dominance of performance-based inference, which is probably automatic.

      We examined the influence of goals on sense of control relative to that experienced when taking action randomly. In the experimental task, participants controlled the direction of a moving dot by pressing the left and right keys at will without a specific goal (the control condition), directed the moving dot to a destination as often as possible (the strong goal condition), or kept the moving dot in the central area of the screen (the weak goal condition) for as long as possible. The results showed that the strong goal impaired the sense of control, but the weak goal did not exert an influence. We concluded that the goal-based expectation influenced sense of control, but the goal-directed action selection did not. Furthermore, we proposed a modified comparator model of the sense of control, offering a promising approach to integration of the predictive and postdictive processes involved in the sense of control.

      The sense of agency refers to the feeling of being able to initiate and control events through one's actions. The "intentional binding" effect (Haggard, Clark, & Kalogeras, 2002), refers to a subjective compression of the temporal interval between actions and their effects. The present study examined the influence of action-outcome delays and arousal on both the subjective judgment of agency and the intentional binding effect. In the experiment, participants pressed a key to trigger a central square to jump after various delays. A red central square was used in the high-arousal condition. Results showed that a longer interval between actions and their effects was associated with a lower sense of agency but a stronger intentional binding effect. Furthermore, although arousal enhanced the intentional binding effect, it did not influence the judgment of agency. (C) 2015 Elsevier Inc. All rights reserved.

      The sense of agency refers to the feeling that one is controlling events through one's own behavior. This study examined how task performance and the delay of events influence one's sense of agency during continuous action accompanied by a goal. The participants were instructed to direct a moving dot into a square as quickly as possible by pressing the left and right keys on a keyboard to control the direction in which the dot traveled. The interval between the key press and response of the dot (i.e., direction change) was manipulated to vary task difficulty. Moreover, in the assisted condition, the computer ignored participants' erroneous commands, resulting in improved task performance but a weaker association between the participants' commands and actual movements of the dot relative to the condition in which all of the participants' commands were executed (i.e., self-control condition). The results showed that participants' sense of agency increased with better performance in the assisted condition relative to the self-control condition, even though a large proportion of their commands were not executed. We concluded that, when the action-feedback association was uncertain, cognitive inference was more dominant relative to the process of comparing predicted and perceived information in the judgment of agency.

      This study examined the effects of instruction on verbal and spatial strategies on the learning about large-scale spaces by people with different levels of sense of direction. 103 participants learned two routes from a video, first without instruction and second with verbalization, spatial operation, or no instruction. For landmark learning, people with a good sense of direction benefited from both verbalization and spatial operation, and people with a poor sense of direction benefited from verbalization only. For survey learning, verbalization had a disruptive effect, and people with a good sense of direction did worse with instruction, either verbal or spatial. By contrast, survey learning by people with a poor sense of direction was not affected by verbalization or spatial operation, indicating their difficulty with survey learning and insensitivity to strategy instruction.

      Many people complain that they do not photograph well. In the present study, we hypothesised that the self-face is memorized more beautifully than reality, which may result in reports of being not photogenic. We took photographs of students who were in the same university course and were familiar with one another. We then magnified or shrunk the size of their eyes (Experiment 1; N = 10) and their mouths (Experiment 2; N = 10). We asked the students to select the picture that seemed most like their classmates' real faces or their own real face. The results showed that there were significant differences between memories of their own and others' faces. Participants selected their classmates' real faces to a greater degree than the modified faces. However, participants tended to select pictures of themselves with magnified eyes and shrunken mouths more often than for their classmates. In Experiment 3 (N = 22), more male participants were included and the influence of gender and mirror-reversed images were examined. We found that there were no significant differences across gender, and the mirror reversal did not change the participants' selections. The bias of self-face recognition may reflect different memory processes for the self and others.

      This study examined how different components of working memory are involved in the acquisition of egocentric and allocentric survey knowledge by people with a good and poor sense of direction (SOD). We employed a dual-task method and asked participants to learn routes from videos with verbal, visual, and spatial interference tasks and without any interference. Results showed that people with a good SOD encoded and integrated knowledge about landmarks and routes into egocentric survey knowledge in verbal and spatial working memory, which is then transformed into allocentric survey knowledge with the support of all three components, distances being processed in verbal and spatial working memory and directions in visual and spatial working memory. In contrast, people with a poor SOD relied on verbal working memory and lacked spatial processing, thus failing to acquire accurate survey knowledge. Based on the results, a possible model for explaining individual differences in spatial knowledge acquisition is proposed. Copyright © 2012 Cognitive Science Society, Inc.

      This study examined how different components of working memory are involved in spatial knowledge acquisition for good and poor sense-of-direction (SOD) people. We employed a dual-task method, and asked participants to learn routes from videos with verbal, visual and spatial interference tasks and without any interference. Results showed that participants with a good SOD encoded landmarks and routes verbally and spatially, and integrated knowledge about them into survey knowledge with the support of all three components of working memory. In contrast, participants with a poor SOD encoded landmarks only verbally, and tended to rely on the visual component of working memory in the processing of route knowledge. Based on the results, a possible model for explaining the differences in spatial knowledge acquisition and SOD was proposed. Copyright (C) 2010 John Wiley & Sons, Ltd.

      Car race drivers are always in dangerous and harsh environments. In order to reduce risks due to mental stress, it is important to evaluate stress during a car race in real-time. The present study measured three physiological indices, heart rate variability, sweat rate, and electromyogram of massester from a professional racer during a car race. However, the relation between these indices, and the types of stress still remains unclear. In the present study, we examined the relations between the three indices and factors linked with these indices during car race with factor analysis. The results suggested that the three physiological indices related to two different factors. One factor scored high when driver saw other nearby car, and was influenced mainly by heart rate variability and sweat rate. We suggest that mental stress is probably high in such scenes, and named this factor as mental stress. Furthermore, the other factor showed high values during urgent accelerations and decelerations, and was influenced mainly by electromyogram of massester. During urgent accelerations and decelerations, the driver probably suffered from large physical discomfort. Therefore, we named the second factor as physical stress. In summary, we found the three physiological indices reflected two different types of stress during car race. Moreover, according to the results of factor analysis, we proposed a method of real-time estimation of both mental and physical stress with the three physiological indices during car race.

      To improve rehabilitation of the diseases which are caused by the mismatch between real body and body representation, it is necessary to understand the mechanism of body representation change. It is assumed that sense of agency and sense of ownership are closely-related with body representation and influence body representation change of the body parts without visual information. We focused on human upper limb and performed experiment with participants on four condition related to sensitivity of agency and ownership. We measure perceived position change of elbow and finger by pointing judgement using motion capture. Visual stimulation which participants given is only virtual hand. Our experiment has revealed that sense of agency influence the body representation change on the body parts which is invisible to participants.

      Sense of Agency (SoA) refers to the experience of controlling external events. SoA is considered to have predictive and postdictive aspect. Recent studies have investigated the relationship between SoA and event-related potentials, but these studies focused only on the postdictive aspect, while the brain activities related to the predictive aspect of SoA remain unclear. In the present study, we focused on readiness potential (RP) and examined the influence of prediction of SoA on RP. In the experiment, participants pressed a key to trigger a tone, and the event-related potentials before and after the key-press was recorded. In the normal predictive condition, all the tones were presented after key-press, thus participants could predict that their key-press would probably cause a tone. In contrast, in the low predictive condition, one third of the tones were presented before the key-presses, thus the causability of key-presses on tones were doubtful. The results indicated earlier RP in the normal predictive condition relative to the low predictive condition, although the difference did not reach significant level due to the small sample size. We will increase participants to confirm the difference in RP between the two predictive conditions in future work. We believe that our work provides important knowledge for the understanding of the neural basis of SoA.

      本研究項目では身体認知・情動が超適応の獲得の過程に与える影響を解明し、身体制御の変化を定量的予測可能な数理モデルを構築し、検証することを目的とする。さらに、数理モデルを基づいて、身体認知・情動を介して、超適応機能を促すモデルベースの介入手法の提案と検証を行う。本年度の主な成果として、1)身体意識の生起と喪失に異なるメカニズムを発見した、2)脳卒中や脳梗塞の後に運動機能が低下した片麻痺患者の回復過程における適応プロセスを調査した、3)身体意識が運動学習に与える影響を検討した。
      本年度の具体的成果を以下に3つ挙げ、それぞれ概要を説明する。
      研究代表者らのグループ(淺間,温)は、運動主体感の生起メカニズムについて、フィードバックと行動の統計的規則性の検出が重要な役割を果たすことを発見し、運動主体感の生起メカニズムを説明するモデルを提案した。また、運動主体感の生起と喪失に異なる脳内神経基盤が存在するという仮説の検証を行った。
      研究分担者の安琪(東京大学)らのグループでは、脳卒中や脳梗塞の後に運動機能が低下した片麻痺患者の回復過程における適応プロセスを調査した。その中でも日常生活において重要な起立動作に着目し、運動障害の程度が異なる患者間において筋シナジーがどのように異なるのか調べた。このことから片麻痺患者の起立動作において、筋シナジーの活動タイミングを指標として、運動回復の過程および適応プロセスを推定できるということが示唆された。
      研究分担者の井澤(筑波大学)らのグループは、超適応の理論的背景を調べる目的で、脳が運動学習スピードを適応的に変化させる機構において、学習の効果に対する認識が与える影響を調べた。得られた研究成果は、効率的なリハビリテーションプログラムの立案のためには科学的根拠の提供に繋がると考えられる。

      本研究の最終目標は、「直感」や「勘」のような人間が無意識的に行う認知メカニズムをシステム化し、ロボットに実装することである。その要素技術として、環境に対して強化学習するロボットが適応的に振る舞うために、獲得済み知識を選択して再利用する際に、保存されている全知識を検索するのではなく、予め再利用する「知識群」の候補を選択する手法を確立する。そのために本研究課題では、1)プロトタイプ理論に基づき,知識群をカテゴリに分割する方法論の構築(認知心理学の知見の応用)、2)センサ入力情報等から特徴量とプロトタイプを抽出し、カテゴリを機械学習する手法の開発(工学と認知心理学の融合)、3)活性化拡散モデルに基づきカテゴリから知識群を選択し、複数方策を結合して再利用する手法と強化学習手法の統合(工学的システム開発)、を行う。具体的には、我々が提案する活性化拡散モデルに基づく方策ネットワーク内の方策群を、視覚入力等の環境観測情報から特徴量に基づきカテゴリとして分類し、仮想的なノードとしてカテゴリ内方策の傾向を表すプロトタイプを方策ネットワークに接続する。方策選択では、観測された環境特徴量からプロトタイプを選択し、接続された方策を一斉に活性化することで、方策選択における計算量を削減し、認知的経済性の実現を目指す。
      本研究課題では、提案手法の評価を計算機シミュレーションと実機ロボットにより行う。タスクとして、複数の形状での最短経路問題(静的タスク)、マルチエージェントによる協調搬送作業(動的タスク)で検証する。2019年度は,検証用の小型実機ロボットとして、搬送作業用のフォークリフトによるハンドリング機構を持つ移動ロボットの設計を行った。また,プロトタイプ理論に基づく知識のカテゴリ化について、認知心理学の観点からモデル化の方針について議論した。活性化拡散モデルに基づく方策選択手法の改良を行った。

      運動主体感とは,自分の意識で自分の行動を制御し,外部の事象の変化を引き起こしたという主観的な感覚を指す.この概念は,感覚,知覚と行動との関係を論じる上で,またロボット等を人間が制御する際にキーとなる概念である.しかし,現在まで,手の動きと,視覚 的な対象の関係が主要な関心であり,制御者の身体のグローバルな移動に対する運動主体感という問題は扱われていない.本研究は,操作者自 身の体の全体的な移動に注目し,操作者の視覚的な注意の空間分布と関係づけようとする.身体全体の運動の運動主体感に着目する点,また,それを空間的な注意分布として評価する点に新規性がある.
      上記の展望に基づき,本研究の具体的な目標は以下の2点に集約される.
      1自己移動を伴う身体運動時の知覚・認知特性の一例として,自転車走行時の視覚特性,とりわ け低次・高次の有効視野その他の,知覚・認知特性への効果の検討を行う.
      2その時,運動と視覚入力の整合性(生態学的な妥当性),運動主 体感を操作し,そうした要因の効果の検討を行う.
      自転車走行時の研究はいくつか存在するが,本研究が目的とする自転車走行時の視覚特性,特に注意の空間分布の問題を扱った研究は見当たらない.本研究では自転車をローラー台装置に装着し,低速から高速までの自己移動をシミュレートし,身体が比較的安定した状態で,視知覚・認知特性を検討する.同時に,運動主体感の操作も行い,運動主体感の強さの注意分布への効果をも検討する.本年は,視覚的な運動感を誘発する刺激(背景刺激)として,放射状に拡張・収斂するランダムドットパターンを用い,自転車走行時の視覚の基本特性,低次・高次の有効視野との関係 静止時,および様々な速度での走行条件を組み合わせ,視力,低次・高次の有効視野を計測・比較する実験を実施し,視力,低次・高次の有効視野に関する基本データを取得した.

      本研究は運動主体感に対するメタ認知、すなわち、「自分が制御している」という主観的な感覚に対してどのぐらい確信を持つのかという認識を研究テーマとしている。運動主体感のメタ認知の行動レベルの特徴を解明し、さらにその神経基盤を解明することを目的とする。2019年度は以下の研究を行ってきた。
      (1)運動検出課題を用いて、運動主体感の判断と運動主体感のメタ認知に用いる下位プロセスの違いを実験で検討した。具体的に、3つのドットから自分が制御できるドットを検出する運動検出課題を用いた。自分が制御できるドットにおいて、一定な角度誤差を入れる条件と他人の運動を混ぜる条件を組み合わせ、ドットの運動と自分の運動の間の規則性と予測誤差をシステム的に操作した。そこで、他人の運動の割合を試行ごとにstaircase法で調整し、運動検出課題の正答率を一定なレベルに固定したうえ、回答の自信を問うことでメタ認知のパフォーマンスを測り、規則性検出と予測誤差がメタ認知に与える影響を調べた。この研究はpreregistered reportとして投稿中であると同時に、すでに20人分の被験者実験を行った。
      (2)運動制御の増加と減少を検出する認知プロセス及び神経基盤の検討を行った。まず行動実験において、ドットに対する制御が20%増加または減少の条件を設け、検出感度を検討し、初期の制御レベルの影響を検討した。行動実験の成果をまとめた論文は現在投稿中である。次に、制御レベルが増加または減少することを検出する脳内神経基盤をfMRI実験を用いて検討する予定であり、現在予備実験が終了し、次に本実験に移る段階である。

      運動主体感や身体保持感などの身体意識は,脳内身体表現に基づき実時間で創出される(Fast dynamics).一方,脳内身体表現は知覚運動経験を通してゆっくりと生成・更新され,変容する(Slow dynamics).研究項目B01では,この身体意識に関する脳内身体表現の生成・更新のダイナミクスのモデル化を行った.具体的に、身体意識の創出と脳内身体表現の変容の数理モデル化,認知身体マッピング器モデルの検証,およびモデルベーストリハビリテーションへの応用の検討を行った.

      特別研究員(RPD)温文氏は初年度及び翌年度の最初の4か月間にイギリスのInstitute of Cognitive Neuroscience (ICN), University College Londonに渡航し,Prof. Patrick Haggardのグループと共同研究を行った.運動主体感の生起または喪失によって,注意及び知覚感覚処理の変化について,行動実験および脳波実験を用いて調べた.ICNの研究グループではこの分野の専門家が多数所属し,行動実験及び脳波実験のための被験者データベース,脳波計測装置,実験室が整えているため,当初計画した研究を順調に進めることができた.
      温氏は初年度において運動主体感の生起によって注意の変化及び脳波における特徴的な変化を調べ,運動主体感の生起の時間特性を解明するため重要な成果を得た.これらの成果はJournal of Cognitive Neuroscience及びNeuroImage誌に論文として掲載された.翌年度において,再度イギリスに滞在し,運動主体感の生起と運動制御のモデルを構築し,行動実験を用いて検証を行った.その成果は現在学術論文の投稿準備中である.その後,常勤の研究職に就いたため,特別研究員の採用を年度中に辞退したが,採用期間中に十分な成果を挙げていると言えると考えられる.
