OBJECTIVE Most research on the effects of severe psychological stress has focused on stress-related psychopathology. Here, the author develops psychobiological models of resilience to extreme stress. METHOD An integrative model of resilience and vulnerability that encompasses the neurochemical response patterns to acute stress and the neural mechanisms mediating reward, fear conditioning and ...
Remitting illness such as affective or schizoaffective disorder is appropriately described by a vulnerability model. Clinical evidence is reviewed here to clarify the relationship between the affective-disorder-like and schizophrenia-like symptoms in a schizoaffective episode. A model is proposed which treats vulnerability to schizoaffective and schizophreniform psychosis as the result of two f...
with respect to population growth and agricultural development in ardabil plain, vulnerability assessment of the plain aquifer is necessary for management of groundwater resources and the prevention of groundwater contamination. in this study, vulnerability of ardabil plain aquifer to pollution was evaluated by drastic method. drastic model was prepared by seven effective parameters on vulnerab...
A tentative model of schizophrenic psychotic episodes is presented, based on the evidence that certain characteristics of individuals may serve as vulnerability factors and that environmental stressors may precipitate psychotic periods in vulnerable individuals. Certain information-processing deficits, autonomic reactivity anomalies, and social competence and coping limitations are viewed as po...
The triple vulnerability model (Barlow, 2000, 2002) posits that three vulnerabilities contribute to the etiology of emotional disorders: (1) general biological vulnerability (i.e., dimensions of temperament such as neuroticism and extraversion); (2) general psychological vulnerability (i.e., perceived control over life stress and emotional states); (3) disorder-specific psychological vulnerabil...
A growing body of findings underlines the critical role of the early environment in normal growth and development. Human studies suggest that severe stress during childhood increases vulnerability to development of affective psychopathology in adulthood. Neonatal maternal separation in rodents (rats or mice) is an established model of early stress for studying the neuroendocrine and behavioral ...
vulnerability and contamination risk assessment is of great importance in karst aquifer management. because of vastness of karst in zagros, natural conditions and human activity within the region of aquifer, pollution emission has become one of the most important challenges in front of zagros aquifers. the purpose of this study is to assess marab aquifer vulnerability, using riske model and, de...
Increased vulnerability to aversive experiences is one of the main risk factors for stress-related psychiatric disorders as major depression. However, the molecular bases of vulnerability, on the one hand, and stress resilience, on the other hand, are still not understood. Increasing clinical and preclinical evidence suggests a central involvement of the glutamatergic system in the pathogenesis...
