Biomedical Approach about mental disorders
Biomedical Approach about mental disorders In contrast, the biomedical perspective, shared primarily by mainstream psychiatrists and psychologists, views the cause of mental disorders as physical dysfunction, such as biochemical or anatomical defects. From this standpoint, internal symptoms are the defining aspects of mental illness. Culture may influence the content of specific symptoms (e.g., the religious […]

Cultural Idioms of Distress One prevailing viewpoint, the cultural idioms of distress perspective, posited by Arthur Kleinman, Byron Good, Janis Jenkins and other medical anthropologists, suggests that mental ill ness cannot be separated from its sociocultural context. As stated by Draguns, a particular symptom only becomes an indicator of distress in its ‘‘transaction with the […]

The Schizoaffective Continuum
The Schizoaffective Continuum Although our diagnostic system treats schizophrenia and the affective disorders as unrelated diseases, there is a continuum from schizophrenia to affective disorders, patients with schizoaffective symptoms outnumber those with purely schizophrenic or purely affective symptoms.

Psychopath Signs and Symptoms
Psychopathic Personality Symptoms. The modern usage of the term psychopathy dates from Cleckley’s clinical descriptions. Two of the features, impulsivity and an absence of anxiety, have been the object of motivational hypotheses. Lykken demonstrated poor electrodermal conditioning and/or rapid extinction using electric shock as the unconditioned stimulus and proposed that the electrodermal hyporeactivity reflected low […]

Mania Symptoms of and Symptoms
Mania The genetic contribution to mania is strong, underscoring the need to consider biological factors. Mania appears to fit nicely into the theoretical framework that employs appetitive and aversive motivational systems, as seen in Depue’s attempt to specify a biological substrate for mania within a neurobehavioral framework. With respect to motivational systems, the symptoms of […]

Appetitive and Aversive Motivation in Depression
Appetitive and Aversive Motivation in Depression The constructs of appetitive and aversive motivation are central to behavioral theories of depression. Depression is viewed as associated with the activation of aversive motivation and/or a disruption of appetitive motivation, and the greater emphasis is on the disruption of appetitive motivation. Indeed, disruption of appetitive motivation is a […]

a mechanism underlying substance abuse
Substance Abuse Major aspects of the literature on substance abuse fit particularly well with the motivational model. Although at one time it was argued that drug abuse could be attributed to physiological dependence per se, there has been a substantial move toward the view that ‘‘abuse of reinforcers’’ conveys the essence of drug abuse, either […]
