Dynamic and complex domains, like those found in the military and healthcare require operators to experience and cope with changes in task demands, i.e. workload transitions. The literature has shown individual differences affect a person’s ability to handle workload transitions, but the role of individual experience has not been thoroughly examined. The focus of this work aims to understand how the role of video game experience, affects an individual’s ability to handle workload transitions in the context of simulated unmanned aerial vehicle (UAV) control. Twenty-one participants completed a UAV simulation under four workload scenarios: low, high, gradual shift from low to high, and sudden shift from low to high. Performance was compared across self-reported video-game players (VGPs) and non-video game players (NVGPs). Overall accuracy for VGPs was higher than NVGPs. This line of work provides the foundation to understand the effect of video game experience, which can help inform training programs and workplace design for operators in various data-rich environments.

Psychological Dimensions

Summary: Deterioration in performance associated with decreased ability to sustain attention may be found in long and tedious task sessions. The necessity for assessing a number of psychological dimensions in a single session often demands “short” tests capable of assessing individual differences in abilities such as vigilance and maintenance of high performance levels. In the present paper two tasks were selected as candidates for playing this role, the Abbreviated Vigilance Task (AVT) by Temple, Warm, Dember, LaGrange and Matthews (1996) and the Continuous Attention Test (CAT) by Tiplady (1992) . However, when applied to a sample of 829 candidates in a job-selection process for air-traffic controllers, neither of them showed discriminative capacity. In a second study, an extended version of the CAT was applied to a similar sample of 667 subjects, but also proved incapable of properly detecting individual differences. In short, at least in a selection context such as that studied here, neither of the tasks appeared appropriate for playing the role of a “short” test for discriminating individual differences in performance deterioration in sustained attention.

Types Of Instruction

Abstract Despite numerous positive findings of explicit instruction, this topic continues to engage scholars worldwide. One issue that may be crucial for the effectiveness of explicit instruction is the interaction between cognitive individual differences (language aptitude and working memory) and types of instruction. In this experiment, 128 learners of Spanish were randomly assigned to four experimental treatments and completed comprehension-based practice for interpreting object-verb and ser/estar sentences in Spanish. Results revealed that the various combinations of rules and practice posed differential task demands on the learners and consequently drew on language aptitude and working memory to a different extent. We argue that not only are rules and practice both necessary, but that their suitable integration ameliorates task demands, reducing the burden on the learner, and accordingly mitigates the role of participants’ individual differences, thus making a substantial difference for the learning of second language grammar.

This paper looks at the trends in design procedures in Unmanned Aerial Vehicles (UAVs). Rapid advances in technology are enabling more and more capability to be placed on smaller airframes which is spurring a large increase in the number of UAVs being deployed in the army. The military role of UAV is growing at unprecedented rates. The UAV is an acronym for Unmanned Aerial Vehicle, which is an aircraft with no pilot on board. UAVs can be remote controlled aircraft (e.g. flown by a pilot at a ground control station) or can fly autonomously based on pre-programmed flight plans or more complex dynamic automation systems. A variety of design configurations are in use. The primary driving parameters in all UAVs is the need for maximizing available wing area and wing effectiveness, while minimizing the required storage volume. The major factors in determining the relative merit of the different concepts are the evaluation of structural viability, mechanical complexity and overall system survivability by G forces. This paper examines some of the design methodologies and hardware-in-the loop simulation environment to support and validate the UAV hardware and software development.

The Individual

The recent increase in the incidence of shiftwork has been accompanied by a change in the type of task typically performed by the shiftworker. The technological advances which have produced both these effects have meant that the shiftworker is more likely to be engaged in cognitive, mentally taxing tasks than the predominantly perceptual-motor ones typical of earlier times. Contemporary research on time of day effects in performance efficiency has indicated that these task changes may be crucially important in determining on-shift performance, and hence the choice of the individual and shift system that is most suitable. Evidence is reviewed on task demands, the effects of different shift systems, and the role of individual differences. A descriptive model is proposed in which on-shift performance is seen to be dependent on the type of task, type of shift system, and type of person, with the three factors interacting via the worker's various circadian rhythms.

Aerial Combat

The following study is devoted to the phenomenon of unmanned aerial vehicles used throughout known history on the battlefield or for military purposes. The purpose of the following text is to familiarise the reader with an overview with the contemporary and historical employment of the unmanned vehicles on the battlefield. The study also aims to show that the concept of unmanned combat vehicles, also unmanned aerial combat vehicles, is far more ancient than is it is widely known. The article is based on theoretical research methods, mostly multinational academic literature. The author starts with an introduction on the role of limiting soldiers’ fatalities and the concept of removing military men from the battleground. Then, the author presents known examples of using unmanned ships in battles from Thucydides’ times to the invention of the Hell-burner of Antwerp. Further, the case of first unmanned combat aerial vehicle is presented, the bombing balloons from the nineteenth century, followed by a more contemporary study of the military use of unmanned aircrafts. The article is concluded with an analysis of the present employment of drones when they tend to substitute manned aircrafts on various occasions, especially when a mission is deemed “dull, dirty or dangerous”.

Unmanned Aerial Vehicle (UAV) has been used in military application even during the conflicts in World War II. The utilization of UAV was further expanded during the Vietnam War and the role of “eye in the sky” has seen UAV became the ultimate ISTAR (Intelligence, Surveillance, Target Acquisition and Reconnaissance) tool for almost all conflicts. The evolution of UAV in various sizes and features will see UAV saturating the battlefield theater’s cloud in the future. This paper is to present the concept of operations of UAV in the military, segmented by units in battle to enable researchers to concentrate their research on types of UAV to suit the needs of the Malaysian Army. Using effective firepower range of all Malaysian Army arsenals and the commonality in terms of tasking, this study is able to establish the classes in terms of range needed for UAV in the Malaysian Army. From the observation, it is clear that the majority of the intended UAV will be operating in the less than 3 km combat radius.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.
