Schizophrenia is a severe mental illness where contact with reality and insight are impaired, an example of psychosis. Section 1: Diagnosis and Classification of Schizophrenia. Classification is the process of organising symptoms into categories based on which symptoms cluster together in sufferers.
Social psychologists study how our behaviour is influence by the presence and actions of others. In this topic we will look at how social psychology can explain why we obey and why prejudice occurs. In Social Psychology, surveys are used to collect data. This helps to collect data looking at attitudes.
Evidence to support this is Gottesman (1991), Kety et al (1968) and Tienari (1994). These studies also support that the environment is important in schizophrenia, so the genetic theory is only half right.
Gottesman and Shields. The aim of the study was to review research on family, twin and adoption studies to test for evidence of a genetic cause of Schizophrenia. The participants were 711 participants of adoption studies, 210 monozygotic twins and 316 dizygotic twins studied. The method was a review article of 3 adoption and 5 twin studies between 1967 and 1976. The procedure looked at the.

The twin study, Gottesman and Shields 1966, found that although genes do appear to play a role in schizophrenia because the concordance rate was higher in MZ twins than DZ twins, environmental factors must also be important as the concordance rate for MZ twins was only 42%.
Background Research Children who have one parent with schizophrenia or one parent with manic depression have similar risks in being diagnosed with the same disorder Read through the Gottesman study on pages 29-30.This is an opportunity for you to ask any questions about the study.
Gottesman and Shields confirmed that the average concordance rate for monozygotic twins is 46% whereas is it only 14% in dizygotic twins. These averages were worked out from five studies that they conducted. Adoption studies can separate the environment from genes. An early adoption study by Heston in 1966 of 47 mothers with schizophrenia whose.

The risk of schizophrenia in the general population is 1%. Gottesman and Shields carried out early familial studies and gave % likelihood rates for various relatives. For example, if you have a parent with schizophrenia, the life-time risk of schizophrenia for you is 5.6%. Family studies have confirmed that the disorder does tend to run in.
THREE ESSAYS ON FINANCIAL MARKETS AND MONETARY POLICY Abeba Siraj Mussa, Ph.D. Western Michigan University, 2011 The global financial crisis triggered by fallout from the sub-prime mortgage market in the U.S. has led economists to focus attention on the role of monetary policy in the crisis.

To investigate in a large sample the probability of a child, with 2 parents with a psychiatric illness, being diagnosed with a mental disorder.
Apparently, people who share the greatest number of genes with the people who have schizophrenia, have an increased risk of developing schizophrenia themselves. Gottesman and Shields reviewed the results of 5 twin studies looking for concordance rates for schizophrenia (4). It was found that in MZ twins there was a concordance rate of 35-58%.

This review describes the strategy of using elementary phenotypes for neurobiological and genetic linkage studies of schizophrenia. The review concentrates on practical aspects of selecting the phenotype and then understanding the confounds in its measurement and interpretation.
