Biological Explanations Of Phobias

Genetics could explain why some individuals inherit the condition. breaker point but not hearty 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 hereditary component is to look at family history. Phobic commode ar more likely to have close comparatives with phobias than non-phobic people. even so this is inconclusive as families all share the same milieu. surge 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 cope with from Torgenson.He put up a 31% harmony compute for agoraphobia in MZ correspond but a 0% ordain in DZ jibe. In addition Bennett Levy engraft that close to people have a greater fear of animals that are considered harmful and awkward (e.g snakes) than of other animals-suggesting we are all natural with a deft ness to fear certain objects. Also Fyer et al (2000) found that phobic individuals had 3x as many phobic relatives than matched controls. similarly 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 personality 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 environment 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 unsurprising tha t phobia runs in families, clearly families ! provide the ideal environment for vicarious 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 financial backing family and twin studies normally live together which is a just flaw. It is a problem...If you fatality to get a full essay, lodge it on our website: OrderEssay.net
