Abstract The purpose of this study was to test the usability of ultrasound as a visual feedback tool in L2 pronunciation training. Six Japanese-speaking learners, aged 28–33 years, participating in a course in French phonetics for L2 learners, took part in the study. Four of them received three individual 45-minute lessons of ultrasound pronunciation training. The other two participants did not. Articulatory and acoustic data of French isolated /y/ and /u/ and Japanese [ɯ] were recorded before and after the ultrasound training, as well as two months later for the learners receiving the training. The analysis of the articulatory data revealed that three speakers with ultrasound feedback improved in the production of the French vowels, the contrast between them, as well as the contrast between the two French vowels and the Japanese [ɯ], suggesting that ultrasound may be a useful tool in second language pronunciation learning.

Practical Information

In this article, a survey of current psycholinguistic techniques relevant to second language acquisition (SLA) research is presented. I summarize many of the available methods and discuss their use with particular reference to two critical questions in current SLA research: (1) What does a learner’s current knowledge of the second language (L2) look like?; (2) How do learners process the L2 in real time? The aim is to show how psycholinguistic techniques that capture real-time (online) processing can elucidate such questions; to suggest methods best suited to particular research topics, and types of participants; and to offer practical information on the setting up of a psycholinguistics laboratory.

Second language (L2) sentence processing research studies how adult L2 learners understand sentences in real time. I review how L2 sentence processing differs from monolingual first-language (L1) processing and outline major findings and approaches. Three interacting factors appear to mandate L1–L2 differences: ( a) capacity restrictions in the ability to integrate information in an L2; ( b) L1–L2 differences in the weighting of cues, the timing of their application, and the efficiency of their retrieval; and ( c) variation in the utility functions of predictive processing. Against this backdrop, I outline a novel paradigm of interlanguage processing, which examines bilingual features of L2 processing, such as bilingual language systems, nonselective access to all grammars, and processing to learn an L2. Interlanguage processing goes beyond the traditional framing of L2 sentence processing as an incomplete form of monolingual processing and reconnects the field with current approaches to grammar acquisition and the bilingual mental lexicon.

Abstract Sports-assisting technologies have been developed; however, most are to improve performances in individual sports such as ski, batting, and swimming. Few studies focused on team sports which require not only motor ability of individual players but also perceptual abilities to grasp positions of their own and others. In the present study, we aim to validate the feasibility of a visual feedback system for the improvement of space perception in relation to other persons that is necessary. Herein, the visual feedback system is composed of a flying drone that transmits the image to the participant’s smart glasses. With and without the system, the participant was able to see his/her own relative position in real time though the glass. Nine participants tried to position themselves on the line between two experimenters 30 m away from each other, which simulated the situation of a baseball cutoff man. As a result, the error distance between the participants’ position and the line significantly decreased when using the system than that without the system. Furthermore, after participants practiced the task with the system the error decreased compared to that before the practice. In conclusion, the real-time feedback system from the bird’s-eye view would work for improving the accuracy of space perception.

Abstract Background: Visual feedback from the center of pressure (COP) on the benefits of standing quietly remains controversial. The study was to investigate the adaptive effect of COP real-time visual feedback training provided by smart wearable devices on standing in silence. Methods: Thirty healthy female college students were randomly divided into three groups (visual feedback balance training group (VFT), non-visual feedback balance training group (NVFT) and control group (CG)) .Two force plates were used to calculate the coordinates of COP anteroposterior (COPAP) and COP mediolateral (COPML).The motion analysis system is used to calculate the coordinates of the center of mass in two directions. Enhanced visual feedback on the screen in the form of fluctuating in different directions, VFT received real-time visual feedback from Podoon APP for training, the NVFT only performs open eye balance without receiving real-time visual feedback. The CG group did not receive any visual feedback. The training lasted 4 weeks, the training lasts 30 minutes at an interval of 1 days. Results: After four weeks of balance training, the results showed that visual feedback training can improve the stability of human posture control by one leg stance and tandem stance static balance training on VFT intelligent App. The parameters of COPML/AP max displacement, COPML/AP velocity and COP radius and COP area in the VFT were significantly increased (p＜0.05).Conclusion: The conclusion shows that COP real-time visual feedback training provided by smart wearable devices can reduce postural sway better and improve body balance ability than general training when standing quietly.
