Biological reason of phobias

Innate factors

One biological justification for the reason for phobic disorders suggests that we are able to relate it back to our genetics. This theory values the ‘nature' area in the character vs foster debate. This theory uses twin research to try and individual genetic factors from environmental factors in order to draw a causal realization between genetics and phobias. If a better concordance rate was found between MZ and DZ twins we're able to suggest a genetic inheritance for the phobia. Kindler predicted a 67% heritability rate pertaining to agoraphobia, 59% for bloodstream injury, 51% for social phobia and 47% intended for animal anxiety. This shows that there are innate factors which in turn influence the development of a phobic disorder and those with a phobic relative happen to be greater susceptible to develop a phobia.

This theory suggests that phobics might have developed an oversensitive dread response which could explain for what reason they are thus anxious inside the presence with their feared stimuli, called the adrenergic theory. This can be discussed through the functioning of the ANS which settings organs induced in excitement levels, such as the center. Individuals who receive abnormally large levels of sexual arousal levels in the ANS would show higher amounts of adrenaline that might result in anxiety attacks and improved anxiety that the same will happen again the moment exposed to the feared stimuli. This suggests that individuals who get an oversensitive fear response are more likely to develop phobias because they inherit a genetic predisposition to exhibit even more fearful features in the presence of scared stimuli than non-phobics.

Assisting evidence with this theory originates from a study by simply Fyer ain al. they will found that probands acquired 3 times as many relatives that experienced phobic disorders than usual controls. This gives evidence to back up the theory as it suggests that there is a high heritability rate between probands and family members, implying there must be a genetic origins for the trait.
