Beschreibung:
Psychogenetics, the study of heritable factors in mental functioning, is just beginning to emerge as a well-defined discipline. Much of our information on genetic factors in human behavior, both normal and abnormal, has been derived from twin family studies. Such studies have been particularly fruitful with respect to schizophrenia. Although the precise etiology of this psychosis is still unknown, data pointing toward the operation of genic elements have been consistent as well as replicable. As for traits falling into the normal range of variation, extensive investigations have been carried out with respect to intellectual performance during the past century, and here, too, constantly accumulating evidence indicates that genetic factors strongly influence measurable intellectual functioning at all age levels, including the period of senescence. Thus, despite its popularity among psychologists, the concept of the human mind as a tabula rasa upon which the environment inscribes its diversity is no longer tenable.
