Anecdotal and preliminary evidence suggests that Soldiers returning from a combat deployment engage in an increased number of health risk behaviors. Three potential factors driving this change were examined in this study; posttraumatic stress disorder (PTSD), concussion and traumatic brain injury (TBI), and perceived invincibility. We studied members of a(More)
Anxiety sensitivity (i.e., the disposition to react to autonomic arousal with fear) has taken a central role in recent conceptualizations of anxiety. However, questions regarding the dimensional nature of anxiety sensitivity remain. In particular, the factor structure of anxiety sensitivity is unexplored in nonadult populations. The factor structure of the(More)
Risk-taking propensity can be influenced by sensation-seeking traits and self-perceived invincibility. We hypothesized that the latter factor may reflect a stable trait that endures across situations and may influence risk-taking behavior. We developed and validated a 20-item scale, the Invincibility Belief Index (IBI) to measure this construct. The IBI(More)
Participants were asked to draw inferences about correlation from single x,y observations. In Experiment 1 statistically sophisticated participants were given the univariate characteristics of distributions of x and y and asked to infer whether a single x, y observation came from a correlated or an uncorrelated population. In Experiment 2, students with a(More)
INTRODUCTION Research has shown that tactile displays are an effective tool for augmenting spatial orientation and situation awareness information provided to aircraft operators. The tactile situation awareness system (TSAS) has been shown to improve flight performance in conditions of degraded visual environments and to safely maintain performance during(More)
INTRODUCTION Providing information via the tactile sensory system allows the pilot to increase awareness without further taxing the visual and auditory perceptual systems. In this study, tactile cues were presented to pilots for target orientation during a simulated helicopter extraction over a moving target. The efficacy of the cues provided by the tactile(More)
