Final answer:
Psychologists are least likely to suggest that neglectful child-rearing practices are a primary factor in the development of schizophrenia. Instead, a combination of genetic factors and environmental stressors are seen as pivotal, with particular emphasis on genetic vulnerability and disturbed home environments.
Step-by-step explanation:
Psychologists are least likely to suggest that neglectful child-rearing practices contribute(s) to the development of schizophrenia. Research indicates that a combination of both genetic vulnerability and environmental stress is necessary for schizophrenia to develop, and that genetics alone do not tell the full story. Evidence from studies by Tienari and colleagues shows that the risk of developing schizophrenia is significantly higher for adoptees with a high genetic risk raised in disturbed family environments. Meanwhile, prenatal viral infections, dopamine overactivity, and shrinkage of cerebral tissue are all factors that have been linked to the disease with prenatal viral infections spotlighted in the 2004 study by Brown et al. The dopamine hypothesis of schizophrenia, proposed by Snyder in 1976, and the shrinkage of cerebral tissue are also acknowledged contributors to the development of schizophrenia.
