Document Summary
Etiology the cause, or set of causes, of a disorder. If a set of factors causes symptoms of an anxiety disorder, then removing those factors should alienate those symptoms. Biological model: assumes that a psychological disorder results from malfunction in the brain twin studies determine whether a disorder has a genetic link. Abnormal brain structures may underlie psychological disorders, such as specific phobias, social anxiety disorder, and panic disorder. Concordance: if two twins share a trait the hereditability of a separate disorder can be estimated by comparing the concordance rates of twins and the compare. Specific genes: if identical twins are more likely to share a specific disorder than fraternal, genetics plays a large role. Neurotransmitter activity is part of the etiology of psychopathology abnormal levels may cause disorders. Drug therapies aim to alter nt activity levels back to their normal.
