Using a simulated Emergency Medical Services (EMS) dispatch center during multi-casualty incident management, this study explored whether the presence of a separate situation display in a Command and Control (C2) setting might require attention at the expense of attending an individual task display, and how it influenced performance and situational awareness. Overall, participants always attended the task display more than the situation display. However, the situation display drew attention at the expense of attending less the task display. The presence of the situation display was related to improved performance and better situational awareness (SA), particularly in the projection level of the SA, which could account also for the better decision-making performance. Participants may have developed an attention allocation strategy to effectively utilize the information of the situation display and execute their tasks on the task display.

Phase-locked loops (PLL) is a phase and/or frequency tracking system, widely used in communication and control systems. The sinusoidal multiplicative type PLL still remains a recurrent model, due the fact that its derivation is originated from the maximum likelihood approach. In this note, it is showed as a generalized product, called q-product, which can be used to implement the phase detector and improve some important parameters of the PLL system, as the block linearity and pull-in characteristics. Numerical examples are presented in order to illustrate the proposal.

This study investigated heart rate (HE) and respiration functioning during rifle shooting to test hypotheses derived from Schwartz's (1979) systems and disregulation theory, and to compare biofeedback with verbal instruction in developing awareness and control of autonomic patterns. Male subjects (N = 8) were pretested to determine HE and respiration patterns affecting performance. They were then divided into two equal groups and given either auditory biofeedback or verbal instruction. The auditory-biofeedback group received continuous pattern feedback through earphones while the verbal instruction group received only presession instruction without feedback. Each group trained for five sessions of 40 shots each. Following training, two 40-shot sessions were conducted. A scaled interview was administered pre- and posttraining to determine awareness/control of autonomic functioning. Compared to the verbal instruction group, the results showed that the biofeedback group significantly improved performance and consistency of the desired pattern and had significantly greater awareness/control of the autonomic pattern. The results supported the systems and disregulation theory as well as the viability of biofeedback for altering imbalances within the systems.

This paper examines the application of order-or-processing networks to the simulation of performance of a complex skill, the copying of high-speed Morse code. A sequence of processing stages and memory buffers is described that is presumed, on the basis of earlier work, to represent the task. Two models of this sequence, distinguished by their assumptions regarding concurrent processing of characters, are also presented. Simulations were run on these models to find the parameters that yielded the best fit to performance data from 19 students undergoing the early stages of military Morse code training. The implications of the results to an analysis of early performance and the potential benefits of applying the same technique to data obtained from students late in training are discussed.

AbstractPurpose. The effects of practice were analyzed in the control of fast and accurate spatially constrained movements. Methods. Twenty men (20-26 years old) evenly divided into an experimental and control group were analyzed in three time periods: pre-test, post-test, and retention. Discrete Aiming Task ver. 2.0 software simulated Fitts’ task (1954) and provided kinematic analysis of mouse cursor movements (displacement, velocity, and acceleration). The task consisted of using the mouse to click on two parallel targets as fast and accurately as possible. Four target widths (W = 2.0, 1.0, 0.5, and 2.5 inches) and three distances between the targets (D = 2.0, 4.0, and 8.0 inches) were used to provide indexes of difficulty (ID) from 1 to 6 bits. The experimental group performed 108 practice trials (three blocks of 36 trials on different days) while the control group had no practice. Results. Movement time (MT) decreased in the experimental group largely due in part to a reduction of time used for feedback. It is suggested that the improvement in performance as a function of practice occurred through the interdependence of programming and the feedback process. As the task was practiced, there was decreased need for feedback due to better pre-programming of the primary submovement and the improved use of sensorial feedback information. This strategy and a lengthened deceleration phase can help explain the paradigm of fast and accurate movement as a result of practice. Conclusions. Despite the improved performance changes as a consequence of practice, Fitts’ Law proved to be robust enough to predict MT as a function of ID.

4C/ID model is a typical model that it develops students' complex ability. The effectiveness of 4C/ID model is approved by many scholars of vocational education and higher education fields. This research takes interactive self-introduce skill training of primary school English as an example, and relevant experiments were carried out based on the instructional design of 4C/ID model for the need of developing complex skill in elementary education. Research shows that 4C/ID model can be applied to develop primary English complex skills. Compared to other traditional English teaching model, 4C/ID model is beneficial to improve pupils' oral English ability, improve self-directed learning ability and close the achievement gap of students and so on. However, the deficiency of 4C/ID model is that it cannot improve students’ learning goal skill and it cannot strengthen students’ knowledge memory and so on.
