A computer-controlled rehabilitation for aphasics with writing impairments is presented. Subjects were asked to type words under dictation. Each time a letter was typed in its correct position, it was displayed on a screen. If the contrary, the error was not displayed, thus avoiding visual reinforcement of false choices. This method of rehabilitation has proved efficient as concerns typewriting. More importantly, some learning transfer to handwriting was observed at the completion of experimental training. The results showed a significant reduction in the number of misspelled words as well as in the erroneous choice and serial ordering of letters. The stability of the observed improvement is discussed in relationship to variables such as the time elapsed since brain damage and the type of writing difficulty.

The College of Education at Kent State University has recently implemented a computer-controlled advising system for use by undergraduate education students. This computer program provides information in a variety of different areas including descriptions of various education programs, deadlines and applications, student teaching, and other topics that may be helpful to these students. Preliminary evaluation shows that the system is easy to use and effectively able to answer the questions often asked by undergraduate students in the College.

The Stability

Examining whether human cognitive performance is affected by environmental conditions requires stable performance measures prior to stressor exposure. This study evaluated the stability and reliability of six computer-based cognitive performance tasks. A Microsoft Excel Visual Basic for Applications (VBA) macro program, the Stability and Reliability Analysis System (SRAS), was developed to evaluate performance of the cognitive tests using three approaches for identifying stability: Graphical Analysis, Learning Curve Fitting, and Statistical Analysis. The results of the comparative evaluation indicated that the SRAS macro program was effective in determining differential stability for the various tasks and measures. Across all tasks, the use of a compound graphical analysis approach was better than a single graph method in terms of providing a more reliable estimation of task stability. Learning curves were fit to each performance measure. For most tasks, the best-fit models were power and logarithmic models. The statistical analysis methods provided conservative estimates of task stability.

Computer-based clinical simulations provide a means for health care students to practice independent choice and action without the necessary constraints of patient safety. A specific diagnostic model is described along with its use in the training and evaluation of health care personnel. The educational viability of the model is examined in terms of a) the apparent reality of the simulation, b) the stability of student performance, c) the relationship of student performance on simulation to performance on more conventional testing methodologies, and d) the applicability of simulation to allied health care personnel. The implications for students, faculty and curriculum of computer-based clinical simulations are discussed.

AbstractLack of standardization and unblinding threaten the research of mechanisms involved in expectancy effects on pain. We evaluated a computer-controlled virtual experimenter (VEx) to avoid these issues. Fifty-four subjects underwent a baseline-retest heat pain protocol. Between sessions, they received an expectancy manipulation (placebo or no-treatment) delivered by VEx or text-only control condition. The VEx provided standardized “social” interaction with the subjects. Pain ratings and psychological state/trait measures were recorded. We found an interaction of expectancy and delivery on pain improvement following the intervention. In the text conditions, placebo was followed by lower pain, whereas in the VEx conditions, placebo and no-treatment were followed by a comparable pain decrease. Secondary analyses indicated that this interaction was mirrored by decreases of negative mood and anxiety. Furthermore, changes in continuous pain were moderated by expectation of pain relief. However, retrospective pain ratings show an effect of expectancy but not of delivery. We conclude that we successfully applied an automated protocol for inducing expectancy effects on pain. The effect of the VEx regardless of treatment may be due to interactions of attention allocation and locus of control. This points to the diversity of expectancy mechanisms, and has implications for research and computer-based treatment applications.

In order to keep the stability of tool’s removal function, it is required that the anastomosis be tight between the tool and workpiece surface in Computer-controlled Optical Surfacing (CCOS). In this paper, the influence of tool’s character on anastomosis status is firstly studied. The relation model on the ratio of radius to thickness, Young's modulus of the tool, normal asphericity and normal arc height of workpiece surface is established, and the macroscopical condition of tight anastomosis is derived in aspheric optics machining. According to the microcosmic distribution of surface error, the mathematical relation between anastomosis error and removal rate is researched. In the end, the influence rule of anastomosis status on the convergence ratio of residual error is analyzed in machining zone. Based on the conclusion of machining instance, it is found that workpiece material would be fast removed in middle contact zone when the peak value of tool’s removal function locates in its center position.

With the ever increasing emphasis on computer-controlled hardware, computerized data processing and computer-based display of results, there is a tendency to forget the operating characteristics of some of the older, more mundane, components of X-ray diffractometers and X-ray fluorescence analysis units. We place our trust in the specifications of the components supplied by the equipment manufacturers and, while usually complete, it nevertheless behooves us to be well aware of the operation of the various hardware components of diffractometers and spectrometers.

Theoretical Results

A general class of car-following models is analyzed where the longitudinal acceleration of a vehicle is determined by a nonlinear function of the distance to the vehicle in front, their velocity difference, and the vehicle’s own velocity. The driver’s response to these stimuli includes the driver reaction time that appears as a time delay in governing differential equations. The linear stability of the uniform flow is analyzed for human-driven and computer-controlled (robotic) vehicles. It is shown that the stability conditions are equivalent when considering ring-road and platoon configurations. It is proven that time delays result in novel high-frequency oscillations that manifest themselves as short-wavelength traveling waves. The theoretical results are illustrated using an optimal velocity model where the nonlinear behavior is also revealed by numerical simulations. The results may lead to better understanding of multi-vehicle dynamics and allow one to design cooperative autonomous cruise control algorithms.
