Extract

Twin studies and investigations into the relationship between schizophrenia-like psychosis and cerebral dysfunction are of considerable interest. Refinement in twin studies has led to less emphasis being placed upon the genetic factor, but the pitfalls surrounding twin techniques, especially with regard to monozygous pairs and the similarity of their environment, have led Penrose (1971) to the opinion that twin study ‘is especially useful, not for genetical researches but in assessing the effects of environmental influences which lead to discordance in identical twin pairs'.
