The Japanese manufacturing industry is now developing global production by establishing production sites in various countries. High quality assurance is regarded as the strong point of manufacturing in Japan (Abegglen, 1958). However, this situation is under threat (Hunt, 1992). The authors consider it vital to make production operators more independent and creative in addition to their engineering capabilities and skills so as to become an intelligence operator. In view of the need to develop a new, creative, human-oriented production system for meaningful working, the authors propose the human-integrated assist system for creative, meaningful work leading to improved productivity. It supports autonomous development of kaizen as the core of this system for the global production strategy. In the wake of the recent rapid expansion of globalization, shortterm training of production operators is an especially critical issue, particularly for ensuring productivity at the start up of local production. To deal with this issue, it is urgent to apply this system to analyze the factors that contribute to the variations in the skill acquisition level of local operators. This is done with a view to establishing a training method that can support them to stably perform work despite the differences in their ability. In definite terms, a brand-new tool, the visual manual, is characterized by (1) convenience, (2) accumulation of know-how, and (3) utilization of CAD and CAE data for further development of advanced skills for intelligence operators. Given these circumstances, the authors have created a new intelligent IT system, which incorporates a training curriculum adjusted to the skill acquisition level of each operator, thereby bringing the training program to a higher level. During the course of implementation, the authors also adopted an aptitude test for assessing the aptitude and inaptitude of operators. This was designed for the establishment of an efficient training system. Its effectiveness has been tested at the Toyota Motor Corporation, a leading automotive manufacturer, as a system that brings about autonomous, voluntary skill improvement in intelligence operators.

Task analysis for the development of a virtual reality (VR) training system requires analysis and identification of the operator’s interactions with the real-world system and of the objectives of training and the trainee’s skill acquisition requirements. A task analysis approach for developing VR training simulators is presented that is based on analyzing the technology and training requirements concurrently. This approach is compared with traditional approaches for system development, with examples provided from the development of a VR training simulator for industrial maintenance and assembly tasks.

Laparoscopic surgery demands highly skilled surgeons. Traditionally, a surgeon’s knowledge is acquired by operating under a mentor-trainee method. In recent years, laparoscopic simulators have gained ground as tools in skill acquisition. Despite the wide range of laparoscopic simulators available, few provide objective feedback to the trainee. Those systems with quantitative feedback tend to be high-end solutions with limited availability due to cost. A modular smart trainer was developed, combining tool-tracking and force-using employing commercially available sensors. Additionally, a force training system based on polydimethylsiloxane (PDMS) phantoms for sample stiffness differentiation is presented. This prototype was tested with 39 subjects, between novices (13), intermediates (13), and experts (13), evaluating execution differences among groups in training exercises. The estimated cost is USD $200 (components only), not including laparoscopic instruments. The motion system was tested for noise reduction and position validation with a mean error of 0.94 mm. Grasping force approximation showed a correlation of 0.9975. Furthermore, differences in phantoms stiffness effectively reflected user manipulation. Subject groups showed significant differences in execution time, accumulated distance, and mean and maximum applied grasping force. Accurate information was obtained regarding motion and force. The developed force-sensing tool can easily be transferred to a clinical setting. Further work will consist on a validation of the simulator on a wider range of tasks and a larger sample of volunteers.

To ensure optimal auditory development for the acquisition of spoken language, children with hearing loss require early diagnosis, effective ongoing audiological management, well fit and maintained hearing technology, and appropriate family-centered early intervention. When these elements are in place, children with hearing loss can achieve developmental and communicative outcomes that are comparable to their hearing peers. However, for these outcomes to occur, clinicians—early interventionists, speech-language pathologists, and pediatric audiologists—must participate in a dynamic process that requires careful monitoring of countless variables that could impact the child's skill acquisition. This paper addresses some of these variables or “red flags,” which often are indicators of both minor and major issues that clinicians may encounter when delivering services to young children with hearing loss and their families.

Effects of four retest-practice sessions separated by 2 h intervals on the relationship between general intelligence and four reaction time tasks (two memory tests: Sternberg's memory scanning, Posner's letter comparison; and two attention tests: continuous attention, attention switching) were examined in a sample of 83 male participants. Reaction times on all tasks were shortened significantly. The effects were most pronounced with respect to the Posner paradigm and smallest with respect to the Sternberg paradigm. The relationship to general intelligence changed after practice for two reaction time tasks. It increased to significance for continuous attention and decreased for the Posner paradigm. These results indicate that the relationship between psychometric intelligence and elementary cognitive tasks depends on the ability of skill acquisition. In the search for the cognitive roots of intelligence the concept of learning seems to be of importance.
