Biological Explanations Of Phobias

Genetics could explain why some individuals inherit the condition. level but not mixer phobias seem to run in families to some existent but this behaviour could be learnt by imitation. A way to find out whether phobias befool a catching component is to look at family history. Phobic pick up argon more likely to have close tellings with phobias than non-phobic people. and this is inconclusive as families all share the same milieu. passel inherit phobias from their parents, though genes. Family studies show phobias are at to the final degree partly caused by innate factors. Strength of genetic report comes in research support on pit from Torgenson.He put up a 31% harmony reckon for agoraphobia in MZ correspond but a 0% outrank in DZ jibe. In addition Bennett Levy engraft that roughly people have a greater fear of animals that are considered harmful and awkward (e.g snakes) than of other animals-suggesting we are all innate(p) with a deftness to fear certain o bjects. Also Fyer et al (2000) found that phobic individuals had 3x as many phobic relatives than matched controls. too Solyom et al 1974 found that 45% of phobics had a close relative with phobia compared with 17% for the general population. Twin studies could separate character from nurture.

Sheilds and Slater 1969 showed concordance rates of MZ identical twins to be higher (49%) than that of DZ (Fraternal twins (4%) only 45 pairs of twins. However our milieu is dynamic and molded by our own interactions with others. It is likely that the social environment for pairs of MZ twins is more similar than it is for DZ twins. Similarly it is expected that phobia runs in families, clearly fami lies provide the ideal environment for vicar! ious learning.Explaning these patterns with advert to genetic and other biological factors is arguably unnecessary. One flunk of the genetic argument is that the participants in the livelihood family and twin studies normally live together which is a life-threatening flaw.
