Fulfilling Positive Stereotypical Expectations, Performance Boosts or Performance Decrements?
… research on effects of negative stereotypes on performance, but less is known about effects of positive stereotypes. Research examining effects of positive stereotypes on performance has found mixed, often competing, results; positive stereotypes have been shown to lead to performance …

Effect of Zolpidem, Zaleplon, and Ramelton on cognitive functioning after awakening from napping
… in the suprachiasmatic nucleus. \r\nCognitive performance following a “full night’s” rest after taking these medications has been more thoroughly studied than performance decrements should return to duty be required. These hypnotics may be used to induce sleep in circumstances not ideal for …

The Effects of Motivation Level and Task Difficulty on Performance on a Vigilance Task
… of these variables as contributors either to performance decrements often found in laboratory research or to performance levels in industrial inspection tasks. Two variables of presumed importance are level of motivation and task difficulty. The purpose of the present experiment was to assess …

The Impact of Sleepiness and Sleep Constructs on Driving Performance
<p>Sleepiness causes performance decrements that lead to thousands of crashes and fatalities annually. Research supports the conclusions that sleep duration and circadian rhythms impact sleepiness and affect driving performance. Conflicting in the literature is whether severity of sleep disorders, …

The effects of alcohol on four behavioral processes: perception, mediation, communication, and motor activity
… it is comprised and alcohol levels at which performance of the task is likely to occur can be postulated, regression equations might be of use in estimating performance decrements on the task under alcohol versus no-alcohol conditions without experimental manipulation. The development of such …

Measuring and modeling the effects of fatigue on performance: Specific application to the nursing profession
… that has been linked to stress, safety, and performance decrements in numerous work environments. Within healthcare, however, a comprehensive definition of fatigue encompassing multiple dimensions has not been considered, but is warranted since nurses perform tasks consisting of diverse …

Driver Response to Simulated Intersections: An Analysis of Workload-Related Variables
… was assessed in three categories of response: performance, subjective, and physiological. A MANOVA was performed on six dependent variables in the 3 (age) by 2 (gender) design. Results indicate significant main effects for both age and gender. The three significant dependent variables were …

Integrating Imperfect Automated Aids Into a Multi -Task Situations
… automated aids may also introduce costs to task performance that are not readily apparent. In four experiments, we examined the impact of interruptions by an alarm embedded within a Cockpit Display of Traffic Information (CDTI) on two types of concurrent tasks; a compensatory tracking task and a …

Ego Depletion-Induced Aberrant Driving in the Post-Work Commute
… demonstrated that prior self-regulation leads to performance decrements in subsequent tasks. This study sought to unite these two lines of research by proposing that ego depletion-induced alterations in attention and motivation are the mechanisms by which workday experiences spill over to the …

The effect of post-resistance exercise water immersion on muscular adaptation and performance in athletes
… increase the risk of injury, illness and performance decrements. Post-exercise recovery strategies (e.g., water immersion) are used in Olympic and teamsport training settings to induce recovery and enhance subsequent performance. Recent suggestions that cold water immersion negatively …

Inciting anarchy in vigilance research: Addressing the limitations of reductionism
… was able to capture multiple facets of vigilance performance, utilize environmental cues that contain bio-meaning, and present demands that evoke bidirectional aspects of vigilance’s functioning. The intersection of these factors was investigated using a combination of subjective, behavioral, and …

The Effects On Operator Performance And Workload When Gunnery And Robotic Control Tasks Are Performed Concurrently
… research was to examine operator workload and performance in a high risk, multi-task environment. Specifically, the research examined if a gunner of a Future Combat System, such as a Mounted Combat System, could effectively detect targets in the immediate environment while concurrently …

The Effects Daily, Maximal of Resistance Exercise on Muscular Function
… becoming "elite". A decrement in an athlete's performance is usually an indicator that overtraining syndrome may be developing. Unfortunately, there is no model that can determine overtraining. A decline in performance results in a depression in maximum muscular force. It is not known whether …

Crash Risk and Mobile Device Use Based on Fatigue and Drowsiness Factors in Truck Drivers
… the U.S. Department of Transportation (US DOT). Performance decrements are typically the result of driver distraction because attentional resources are limited, which are limited; fatigue and drowsiness limit attentional resources further. The purpose of the current research is to gain an …

Cognitive, neuroanatomical and neuroendocrine effects of long-term rotating shift work in a nursing sample
… outbound, transmeridian long-haul flights showed performance decrements on cognitive tasks, reduced hippocampal volumes and increased cortisol levels. The current study aimed to investigate whether work-related sleep disruption caused similar effects among rotating shift-workers from outside the …

Visual Information Acquisition, Decision-making, Pacing and Performance during Time Trial Cycling
… during athletic events to produce the best performance without premature fatigue. Little is understood about the cognitive processes leading to pacing decisions and behaviour. The aim of this thesis was to measure cyclists’ visual behaviour, using eye-trackers, to determine information …

Modeling operator performance in low task load supervisory domains
… causing boredom, lack of vigilance, fatigue, and performance decrements. As more systems are automated and placed under human supervision, this problem will become more prevalent in the future. To mitigate the problem through predicting operator performance in low task load supervisory domains, a …

Effects of instrument panel luminance and hue on simulator driving performance and driver preferences
… For each word presented, six reading and driving performance measures were taken. Also, subjective attractiveness, subjective comfort, and subjective ease of readability of each hue by brightness treatment combination, were measured. Globally, the results tend to indicate that color of …
