Physiological reaction to a perceived threat or harmful event

The fight-or-flight-or-freeze or the fight-flight response (also called hyperarousal or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival.[1] It was kickoff described past Walter Bradford Cannon.[a] [2] His theory states that animals react to threats with a general belch of the sympathetic nervous system, preparing the animal for fighting or fleeing.[3] More specifically, the adrenal medulla produces a hormonal cascade that results in the secretion of catecholamines, peculiarly norepinephrine and epinephrine.[iv] The hormones estrogen, testosterone, and cortisol, also as the neurotransmitters dopamine and serotonin, also bear on how organisms react to stress.[5] The hormone osteocalcin might also play a part.[half dozen] [vii]

This response is recognised as the first phase of the general adaptation syndrome that regulates stress responses among vertebrates and other organisms.[8]

Proper noun [edit]

Originally understood as the fight-or-flight response in Cannon's research,[9] the state of hyperarousal results in several responses across fighting or fleeing. This has led people to calling it the fight, flight, freeze response (or fight-flying-faint-or-freeze, amongst other variants).[10] The wider array of responses, such equally freezing, fainting, fleeing, or experiencing fright,[11] has led researchers to use more neutral or accommodating terminology such every bit hyperarousal or the acute stress response.

Physiology [edit]

Autonomic nervous system [edit]

The autonomic nervous arrangement is a control organisation that acts largely unconsciously and regulates center rate, digestion, respiratory charge per unit, pupillary response, urination, and sexual arousal. This arrangement is the primary mechanism in control of the fight-or-flight response and its part is mediated past two different components: the sympathetic nervous system and the parasympathetic nervous organisation.[12]

Sympathetic nervous organisation [edit]

The sympathetic nervous system originates in the spinal string and its main function is to actuate the physiological changes that occur during the fight-or-flight response. This component of the autonomic nervous organization utilises and activates the release of norepinephrine in the reaction.[13]

Parasympathetic nervous system [edit]

The parasympathetic nervous organisation originates in the sacral spinal cord and medulla, physically surrounding the sympathetic origin, and works in concert with the sympathetic nervous system. Its principal function is to activate the "balance and digest" response and return the body to homeostasis after the fight or flight response. This system utilises and activates the release of the neurotransmitter acetylcholine.[xiii]

Reaction [edit]

The reaction begins in the amygdala, which triggers a neural response in the hypothalamus. The initial reaction is followed by activation of the pituitary gland and secretion of the hormone ACTH.[14] The adrenal gland is activated virtually simultaneously, via the sympathetic nervous system, and releases the hormone epinephrine. The release of chemical messengers results in the production of the hormone cortisol, which increases blood pressure, blood sugar, and suppresses the immune system.[xv] The initial response and subsequent reactions are triggered in an effort to create a boost of energy. This boost of energy is activated by epinephrine bounden to liver cells and the subsequent production of glucose.[16] Additionally, the apportionment of cortisol functions to turn fatty acids into available energy, which prepares muscles throughout the body for response.[17] Catecholamine hormones, such as adrenaline (epinephrine) or noradrenaline (norepinephrine), facilitate immediate concrete reactions associated with a training for violent muscular action and:[18]

  • Acceleration of center and lung action
  • Paling or flushing, or alternate betwixt both
  • Inhibition of stomach and upper-abdominal activeness to the point where digestion slows downwards or stops
  • General effect on the sphincters of the body
  • Constriction of blood vessels in many parts of the trunk
  • Liberation of metabolic energy sources (particularly fatty and glycogen) for muscular action
  • Dilation of blood vessels for muscles
  • Inhibition of the lacrimal gland (responsible for tear product) and salivation
  • Dilation of pupil (mydriasis)
  • Relaxation of bladder
  • Inhibition of erection
  • Auditory exclusion (loss of hearing)
  • Tunnel vision (loss of peripheral vision)
  • Disinhibition of spinal reflexes
  • Shaking

Part of physiological changes [edit]

The physiological changes that occur during the fight or flight response are activated in order to requite the torso increased force and speed in apprehension of fighting or running. Some of the specific physiological changes and their functions include:[19] [20]

  • Increased blood flow to the muscles activated by diverting blood flow from other parts of the torso.
  • Increased blood pressure, heart rate, claret sugars, and fats in social club to supply the body with actress energy.
  • The blood clotting function of the body speeds up in lodge to prevent excessive blood loss in the upshot of an injury sustained during the response.
  • Increased musculus tension in order to provide the trunk with extra speed and strength.

Emotional components [edit]

Emotion regulation [edit]

In the context of the fight or flight response, emotional regulation is used proactively to avoid threats of stress or to control the level of emotional arousal.[21] [22]

Emotional reactivity [edit]

During the reaction, the intensity of emotion that is brought on by the stimulus will also decide the nature and intensity of the behavioral response.[23] Individuals with higher levels of emotional reactivity may exist decumbent to anxiety and assailment, which illustrates the implications of appropriate emotional reaction in the fight or flight response.[24] [25]

Cognitive components [edit]

Content specificity [edit]

The specific components of cognitions in the fight or flight response seem to be largely negative. These negative cognitions may be characterised by: attention to negative stimuli, the perception of cryptic situations every bit negative, and the recurrence of recalling negative words.[26] There besides may be specific negative thoughts associated with emotions normally seen in the reaction.[27]

Perception of control [edit]

Perceived command relates to an individual'south thoughts near control over situations and events.[28] Perceived control should be differentiated from actual control because an individual's beliefs about their abilities may not reflect their bodily abilities. Therefore, overestimation or underestimation of perceived control can lead to feet and aggression.[29]

[edit]

The social information processing model proposes a variety of factors that make up one's mind behavior in the context of social situations and preexisting thoughts. The attribution of hostility, especially in ambiguous situations, seems to be ane of the near of import cognitive factors associated with the fight or flight response because of its implications towards aggression.

Other animals [edit]

Evolutionary perspective [edit]

An evolutionary psychology explanation is that early animals had to react to threatening stimuli apace and did not have fourth dimension to psychologically and physically ready themselves. The fight or flight response provided them with the mechanisms to chop-chop respond to threats against survival.[32] [33]

Examples [edit]

A typical instance of the stress response is a grazing zebra. If the zebra sees a lion closing in for the impale, the stress response is activated as a means to escape its predator. The escape requires intense muscular try, supported past all of the torso's systems. The sympathetic nervous organisation'south activation provides for these needs. A similar example involving fight is of a cat nigh to be attacked by a domestic dog. The cat shows accelerated heartbeat, piloerection (hair standing on end), and student dilation, all signs of sympathetic arousal.[18] Note that the zebra and cat withal maintain homeostasis in all states.

In July 1992, Behavioral Ecology published experimental research conducted by biologist Lee A. Dugatkin where guppies were sorted into "bold", "ordinary", and "timid" groups based upon their reactions when confronted by a smallmouth bass (i.e. inspecting the predator, hiding, or pond away) subsequently which the guppies were left in a tank with the bass. After lx hours, twoscore percent of the timid guppies and xv percent of the ordinary guppies survived while none of the bold guppies did.[34] [35]

Varieties of responses [edit]

Animals respond to threats in many circuitous ways. Rats, for instance, try to escape when threatened but will fight when cornered. Some animals stand perfectly still so that predators will not see them. Many animals freeze or play dead when touched in the hope that the predator will lose interest.

Other animals accept culling cocky-protection methods. Some species of cold-blooded animals change color swiftly to camouflage themselves.[36] These responses are triggered by the sympathetic nervous organization, simply, in social club to fit the model of fight or flight, the idea of flight must exist broadened to include escaping capture either in a concrete or sensory fashion. Thus, flight tin exist disappearing to another location or merely disappearing in place, and fight and flying are oftentimes combined in a given situation.[37]

The fight or flight actions also have polarity – the private tin either fight against or abscond from something that is threatening, such as a hungry king of beasts, or fight for or wing towards something that is needed, such as the safety of the shore from a raging river.

A threat from some other fauna does not always issue in immediate fight or flight. In that location may be a menses of heightened awareness, during which each fauna interprets behavioral signals from the other. Signs such as paling, piloerection, immobility, sounds, and body language communicate the status and intentions of each animate being. There may be a sort of negotiation, later which fight or flying may ensue, merely which might also result in playing, mating, or cypher at all. An example of this is kittens playing: each kitten shows the signs of sympathetic arousal, merely they never inflict existent damage.
