Heightened alertness state -

In this regard, many forms of meditation putatively rely on the ability to sustain, control and monitor attentional processes Malinowski, Both focused attention and monitoring styles of meditation clearly draws from tonic resources, as these forms of meditation rests on attending pre-specified mental objects and monitoring mental events, while staying watchful of mental distractions Lutz et al.

Moreover, mounting evidence shows the enduring impact of meditative training on vigilance and attentional flexibility, as individuals become better at monitoring their own attentional states and avoiding the displacements of attention towards taskirrelevant perceptual or cognitive events MacLean et al.

In regards to our previous discussion about the current views on attentional failures, these. Regardless of both viewpoints, findings emphasize how improvements primarily emerge at the level of tonic alertness, as showcased by the reduction in episodes of mind-wandering following mindfulness training, thereby revealing the plasticity of this attention system Mrazek et al.

Some gains also transpire for the executive network, reflected by improved selection of relevant sensorimotor information and inhibition of irrelevant one Tang et al.

Overall, this nascent research domain highlights the possibility to improve tonic alertness capacities, leading to psychological benefits that translate into better mundane task performance and overall well-being. Further evidence also hints to the fact that meditation improves the management of top-down anticipatory resources, a relevant aspect to phasic alertness.

One notorious example notably shows how meditative practices improve the flexible allocation of attention in the attentional blink paradigm.

In this experimental approach, researchers typically embed two targets in a rapid stream of visual stimuli. Some have argued that this decline follows from some type of temporal bottleneck in attentional processing, whereby attending to the first event prevents the deployment of attentional resources to the second one e.

Using this experimental strategy as a mean to investigate the effects of mindfulness meditation on attention, a research group found that rigorous practice allows practitioners to eventually overcome such limitations by reliably extending their attentional resources across both target events, instead of solely focusing on the first one Slagter et al.

Thus, individuals become better at planning and managing their attentional focus. Practitioners therefore become more proficient at allocating their attention in an effortless manner Wallace, Overall, these overarching findings demonstrate how contemplative practices rely on the alerting system to monitor and maintain attentional resources active.

These mental practices largely draw from the endogenous regulation and reactivation of mental sets. Moreover, they highlight the inherent plasticity of the alerting system. Due to its pervasive nature, vigilance has been the subject of considerable study; researchers have scrutinized the notion of vigilance from different angles across multiple domains of enquiry.

Few, however, have attempted to link this body of work into an overarching synthesis. Relying on a prevalent framework pertaining to the cognitive neuroscience of attention, we herein demonstrate how vigilance represents a core modulator of human cognition and consciousness.

We explain how phasic and tonic alertness provide the conceptual means to understand the effects of vigilance on human performance, while connecting this research to the sciences of hypnosis and.

Critically, we show how the effects of alertness, which largely originate from sub-cortical brain structures concerning arousal, go beyond task performance and extend to the realm of alerted consciousness and contemplative practices.

Accordingly, we consider phasic and tonic alertness as core constructs of human performance and experience. We hope that our account fuels future investigations to explore further intersections across the multiple domains of vigilance.

As such, people fighting in the military or experiencing violence at home may exhibit hypervigilance with good reason. However, hypervigilance can also happen when there is not a real, physical danger.

When this happens, it is as a result of a mental health condition. PTSD is an anxiety disorder that people can develop after experiencing or seeing a traumatic or life-threatening event.

Events that can cause PTSD include:. Hypervigilance is a key feature of PTSD, as people are in fear of re-living the trauma. This can cause them to be constantly on-guard, in anticipation of the trauma happening again. People diagnosed with generalized anxiety disorder GAD or social anxiety may experience hypervigilance.

This is most likely to happen in new situations or when they meet new people. However, there is some debate as to whether anxiety causes hypervigilance, or whether anxiety disorders result from hypervigilant behavior. A study , conducted on rats, found that a hypervigilant state made them more vulnerable to anxiety.

More research is needed to understand whether hypervigilance is a symptom or a cause of anxiety disorders.

There are common triggers that can bring on hypervigilant behavior in those who are affected by it. These triggers include:.

The first step in treatment if a person experiences hypervigilance due to domestic violence or military combat, is to remove them from the dangerous environment. When someone experiences hypervigilance due to a mental health condition, other treatments that may help include:.

As well as taking medication if it is prescribed and attending therapy if they have been referred, people may look for other ways to manage hypervigilance.
