Multiplayer Online Battle Arena (MOBA) games rely primarily on combat to determine the ultimate outcome of the game. Combat in these types of games is highly-dynamic and can be difficult for novice players to learn. Typically, mastery of combat requires that players obtain expert knowledge through practice, which can be difficult to concisely describe. In this paper, we present a data-driven ap...

The aim of this study was to investigate the effects of caffeine on reaction time during a specific taekwondo task and athletic performance during a simulated taekwondo contest. Ten taekwondo athletes ingested either 5 mg·kg⁻¹ body mass caffeine or placebo and performed two combats (spaced apart by 20 min). The reaction-time test (five kicks "Bandal Tchagui") was performed immediately prior to ...

Declaration of interest None. Fundingdetailed in Acknowledgements. There is extensive documentation of the prevalence, severity and correlates of posttraumatic stress disorder (PTSD) in Vietnam veterans exposed to the trauma of combat and war-zone service (Kulka et al, 1990). Research with Vietnam combat veterans has been used to create and refine the DSM criteria for PTSD (Shephard, 2001), to ...

BACKGROUND A significant subgroup of individuals with posttraumatic stress disorder (PTSD) exhibits chronic, unremitting symptomatology that has also been associated with smaller hippocampal volume. The hippocampus plays a significant role in configural processing of contextual cues that facilitates context-appropriate extinction of conditioned fear. We test the hypothesis that hippocampus-base...

While longitudinal posttraumatic stress responses are known to be heterogeneous, little is known about predictors of those responses. We investigated if locus of control (LOC) and coping style are associated with long-term PTSD-trajectories after exposure to combat. Six hundred and seventy five Israeli soldiers with or without combat stress reaction (CSR) from the Lebanon war were assessed 1, 2...

We present the development of a 3D real-time visual Cellular Agent model (VCELL). VCELL is used for simulating land combat and is collaboratively modeled using a cellular agent model based on the Cell-DEVS formalism and an advanced immersive environment based on a 3D real-time visual simulation. VCELL is used to enhance and improve the random selection caused by movement algorithms of Agentbase...

Although data are inconclusive, popular perception has linked military combat, posttraumatic stress disorder (PTSD), and criminal behavior. This paper discusses the multifactorial elements of this association that include both conscious and unconscious parameters of psychologic functioning. Testimony on combat-related PTSD has been presented in the courtroom to support veterans' claims of not g...

The purpose of this study was to examine whether appraisals of desirable and undesirable effects of military service mediated the effect of combat stress on posttraumatic stress disorder (PTSD) symptoms in later life in 1,287 male veterans, aged 44-91 years (M = 63.56, SD = 7.46), 40% of whom had been in combat. The men reported more desirable effects of military service (e.g., mastery, self-es...

This study assessed the contribution of baseline psychological symptoms, combat exposure, and unit support in the etiology of posttraumatic stress disorder (PTSD), and psychological distress. From 2004-2006, 67% of a random sample of 2,820 participants who had been assessed for psychological symptoms in 2002 were reassessed. Baseline psychological symptoms, combat exposure, and unit support fac...

This paper introduces a simple multiagent-based \toy model" of land combat called ISAAC (Irreducible Semi-Autonomous Adaptive Combat) to illustrate how certain aspects of land combat can be viewed as emergent phenomena resulting from the collective, nonlinear, decentralized interactions among notional combatants. ISAAC takes a bottom-up, synthesist approach to the modeling of combat, vice the m...
