These technological advancements have profoundly transformed how millions of people interact with and navigate their environments. However, the impact of display type and body position on motor performance remains underexplored. This study aims to elucidate how these environmental constraints affect bimanual coordination by comparing performance under two display conditions: virtual reality (VR) goggles and projected screen. Participants (<em>N</em> = 12), all right-limb dominant, performed a continuous 1:1 bimanual force coordination task with a 90° relative phase offset using Lissajous plots as visual feedback. Performance was assessed in two body positions (upright and recumbent) manipulated by a tilt table. The results revealed that using VR goggles minimized performance differences between the upright and recumbent positions, suggesting that using VR goggles stabilizes motor coordination by reducing perceptual distractions and mitigating environmental constraints. In contrast, the projection screen condition demonstrated higher force coherence in the 8–12 Hz band during the recumbent condition compared to the upright position, indicative of force synchronization differences related to body position. However, the projected screen group displayed lower absolute error during the recumbent positions. This suggests that while VR goggles support consistent motor output across varied postures by simplifying perceptual input, projection screens may enhance motor synchronization and attention under controlled conditions due to more straightforward visual processing. These findings highlight a trade-off between display types: VR offers stability and adaptability, making it advantageous for tasks that require consistent performance across changing postures, whereas projection screens may be better suited for tasks requiring precise motor control and heightened attentional focus. The study underscores the need for task-specific considerations in the design and use of display environments for training, rehabilitation, and motor coordination tasks.</div></div>","PeriodicalId":55046,"journal":{"name":"Human Movement Science","volume":"101 ","pages":"Article 103360"},"PeriodicalIF":1.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143929470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the pattern formation process of interpersonal coordination is relatively well understood, models like HKB lack an ecological dimension that relates the motor pattern to the environment.

Participants rolled a ball back-and-forth between two targets on a beam, by manipulating the beam inclination either individually or dyadically. In an (earlier reported) first step, 16 participants performed two solo action sessions of the task, allowing us to identify pertinent performance characteristics. Here, those participants were paired into 8 dyads to perform a joint action session, allowing us to assess the solo-to-joint transfer of those characteristics. Over blocks, dyads improved their performance by increasing the ball speed and accuracy. While the relative variability of the beam's inclination angle decreased, the range and the timing of the beam motion remained unchanged. Variables (indirectly) related to ball speed, such as the range and timing of the beam motion, were strongly propagated from solo to joint action, while the variables related to ball accuracy, like the beam variability, were only moderately transferred. Most dyads established an anti-phase mode of coordination, with a significant decrease in phase variability over blocks. We also observed significant asymmetries in the coordination. Dyad members with a better solo-action performance were more likely to lead the interaction.

We recorded temporal elements of the task: response time (RespT), reaction time (RT), movement time (MT), and the time interval between task components (TITC) to analyze performance throughout the acquisition phase and in the retention test, chunking, and the informational aspects related to task performance. Additionally, we investigated online and offline learning processes. Both groups learned the task, but the skilled participants exhibited greater improvements in performance, particularly in the retention test. Best performance of skilled participants appear to be linked to the benefits of chunking in serial tasks.

Despite these differences, especially in terms of informational demands, both groups learned predominantly through online learning process. Increasing skill level enhances performance, and influences the learning of new motor skills in a specific sports domain. This advantage may be explained by the superior chunking ability demonstrated by skilled performers, likely resulting from larger experiences within Taekwondo, which facilitated the recombination of previously learned motor skills.

Fifteen PwPD and 13 neurotypical individuals walked over a 26.8 m pathway under three experimental conditions: usual walking, walking with increased arm swing amplitude, and walking with increased arm swing velocity. Gait step parameters, continuous relative phase and latency between arm and leg movements, and PFC hemodynamics were calculated. ANOVA two-way (groups x conditions) showed that the verbal instructions to increase arm swing amplitude and velocity during walking improved gait step parameters and arm-leg interlimb coordination, without changing PFC hemodynamics.

In the NGC analysis, causal relationships were defined as the size of the weight parameters of the first layer of a machine-learning model trained to predict the future state of a specific time-series variable. To verify this approach practically, we conducted an experiment with 16 pairs of expert baseball pitchers and batters, and input datasets with 27 joint resultant velocity (13 pitchers' and 14 batters' joints) were generated and used for model training. The results revealed that significant causal relations exist among intra- and inter-individual body components, such as “the batter's hands have a causal effect from pitcher's throwing arm.” Although the causality from the batters to the pitcher's body is significantly lower than that from the pitchers to the batter's body, it exhibits a significant correlation with the performance outcomes of batters (R<sup>2</sup> = 0.69).

Young, healthy subjects performed steady-state accurate total force production tasks with and without targets for the individual finger forces. These targets varied in size from 1.5% to 40% of the task total force level.

First, variability in the sharing of total force between the individual finger forces, based on practice, that can be seen from the very beginning of trials. Second, negative covariation of finger forces along individual trials based on visual feedback and, potentially, on loops within the central nervous system.
