Research On Vigilance And Sustained Attention

Dr. Gilmartin believes that hypervigilance is the way law enforcement officers must view the world. He stated that “officer must learn to perceive the world as potentially hazardous in order to survive the streets.” Hypervigilance allows an on-duty officer to develop the perceptual set of skills for officer safety. Every decision made by officers is based on the set of perceptual set of hypervigilance. A hypervigilance officer may experience increased blood pressure, blood sugar, heart rate and etc. But effects of hypervigilance can take a toll on an officer personal life and psychologically over a significant course of time.

Growing up in a generation where technology is at our fingertips, the brain changes its organization and functioning to accommodate the abundance of stimulation forced on it by the modern world. I recognize where Restak’s logic comes from because individuals are so dependent on phones and laptops that it becomes a challenge for people to complete work on their own. People feel as if it is necessary to have an electronic device by their side, tricked into believing multitasking is an acquired skill when in reality the brain is struggling. With the constant use of extra devices, Restak suggests “multitasking”

In the excerpt from Richard Restak, he talked about how the plasticity of our brain is changing the way we do things toay. The human brain is changing everyday and there is no way anyone can stop it. Richard Restak, an expert on the brain, talks about how the plasticity of our brains is changing constantly. He believes that this change is negatively hindering our ability to focus and produce a single task. The rewiring of our brains is forcing us as humans to make many changes to our everyday lives, and the main change it is causing us is that in order to function we need to multitask. Multitasking is the new thing today; everyone wants to be able to do as many things as

Sam Anderson book reviewer for New York magazine and writer of many articles like, In Defense of Distraction, Anderson has primarily become interested in the way culture and our habits of reading has drastically changed with technology. In the article In Defense of Distraction, Anderson explores the poor attention one has developed throughout the decades and how this attention has distracted the human mind in a way that it has centered to our cultural attention. It is an inevitable habit we seem to apply in our everyday life’s, in our yoga class one a week, the cancer slowly spreading across our body, the pretty little liars show that is shown every Tuesday that seems to not be enough. We seem to pay attention all the time

Multitasking, helpful or harmful? In Alina Tugend’s “Multitasking Can Make You Lose…Um…Focus”, Tugend explores multitasking in several ways. Explaining how we as humans sacrifice focus “shifting focus from task to task gives illusion that we’re simultaneously tasking”. Also, how our brains react to operating and trying to do more than one task at once. Only one or two visual stimulants can activate our neurons at one particular time. Lastly, how we can recreate boundaries and cope with everyday life and multitasking. Tugend reiterates several times the importance of one task at a time so we as humans can effectively complete tasks to the best of our abilities instead of giving partial focus and not efficiently completely a task. Multitasking is very beneficial at times, but more often there are significant downfalls; it is crucial we learn how to manage the downfalls of juggling tasks, events, conversations, and daily events.

In the essay “Multitasking can make you lose … Um … Focus” Alina Tugend exams why multitasking can make you lose focus. Tugend explains what multitasking is in the first section she also explains why it is bad. She then brings in a professor to explain how multitasking works in a scientific way. Alina Tugend then uses case studies to show how multitasking can cause loss of focus and impairment in motor activities. She then shows how multitasking can actually delay your progress on completing projects by constantly switching to different tasks. Tugend then sums it all up by trying to teach us how to better ourselves and to not multitask.

In “Multitasking Can Make You Lose...Um...Focus,” Alina Tugend examines the negative aspects and many disadvantages that occur through multitasking. Tugend begins by stating that multitasking is the norm for today’s fast paced society; however, in reality it is pulling focus from the task at hand. The author continues on to cite various researchers who express that the brain cannot simultaneously do two tasks at once and is actually just flipping back and forth between tasks rapidly. Although multitasking seems like a time efficient method, Tugend reveals, it is actually creating a large amount of stress and pressure on the individual. Furthermore, the author notes that multitasking actually pulls away from the task at hand creating a great time loss. Tugend even goes on to explain that multitasking is proving to be bad for innovation by not allowing an individual to think in depth about one task for an extended period of time. With Tugends article in mind I agree that multitasking puts a lot of stress and pressure on the individual, creates a loss in time, and is awful for innovation.

Attention is considered to be a core cognitive process, it refers to how people actively process specific information in the environment. Attention refers to how people select from information and stimuli in the environment, facilitating processing of some of the stimuli and inhibiting processing of others. "Everyone knows what attention is, it is the taking possession by the mind in clear and vivid form, of one out of what seem several simultaneously possible objects or trains of thought...It implies withdrawal from some things in order to deal effectively with others, and is a condition which has a real opposite in the confused, dazed, scatterbrained state. “This definition of attention was proposed by psychologist William James (1890). This review will focus on literature that gives explanation to selective attention. Selective attention refers to the process where a person is able to select out of many stimuli and focus on the one they want and ignore other stimuli.

Also, our arousal will only last for a certain amount of time, our attention can easily be distracted from our current task to something else. Vigilance is being about to keep your attention on one thing for a long period of time, regardless of different distractions. For example, when I’m reading a weekly lesson I can only process so much information at once (attention) before I get distracted by something else. However, when I’m taking a test, I have to be able to focus my attention on that test for a good stretch of time

Hypervigilance by definition is,“A worldview based on a “threat based” biologically driven perspective in which everyday events unfold as potentially dangerous to officer safety.” (Gilmartin, 2002 p.6). A police officer works in an environment where they have to be reactive and it is hard to turn off. This can exhausting and can lead some to depression. Officers in turn will work side jobs to fulfill the need to constantly have the feeling of being hypervigilant and be around their work family. However, this can cause issues within a home or in a relationship. It can take a negative toll on the body physically. It causes increased blood pressure, respiration, body temperature and other functions. (2002). It is imperative that an officer finds

In this experiment we tried to replicate the Monsell 2003 Task Switching experiment. 18 Participants took a brief task-switching test via program Revolution Maker©. Each trial was randomly assigned. The participants were presented with numbers one through nine and on each trial had to react to the number, to identify either its odd or even or if the magnitude was either less than 5 or more than 5. We hypothesis that when individuals are engaged in a cognitive task there is a time cost that occurs when asked to switch between tasks as opposed to repeating tasks.

The clumping together of knowledge, growing low attention span, and separation of focus has not only made it harder to avoid distraction, but it also has resulted in less efficient work and performance. It was discovered in a study that when the participants were told to switch between solving math problems and classifying geometric objects, it took longer for them to solve each problem. As the tasks got progressively more complex and difficult, it took a significantly longer time for the participants to complete the assignment, especially those who were unfamiliar with the subject (Rubinstein). This revelation is particularly

In modern aviation, pilot fatigue has become a vital problem that needs urgent intervention. The full effect of fatigue is frequently unforeseen however, many of its harmful effects have been known for a long time. When comparing with individuals who usually have enough rest, individuals who suffer from fatigue act slowly, have difficulties in memory, and are involved in many mistakes. In addition, the negative impact can or may lead to aviation accidents and errors (Caldwell, Mallis, Caldwell, Paul, Miller, & Neri, 2009).

Vigilance is defined as the action or state of being alert and watchful. It is concerned both with what is and what will be. Thus it is important to be Vigilant in the army for many reasons. Not the least of which being it could keep you and your buddies alive despite the world’s best attempts to make you otherwise. But it means more than just staying awake and alert at guard duty. It means both being mentally and physically prepared to react to changing conditions and to being aware and cognizant of the current conditions. There are three important categories to discuss here and expound upon. The First is Vigilance
