FIGURE 12.11 A combination of vulnerability and stress may produce psychological problems. The top bar shows low vulnerability and low stress. The result? No problem. The same is true of the next bar down, where low vulnerability is combined with moderate stress. Even high vulnerability (third bar) may not lead to problems if stress levels remain low. However, when high vulnerability combines with moderate or high stress (bottom two bars) the person “crosses the line” and suffers from psychopathology.

In people suffering from schizophrenia, a reduction in dopamine activity can quiet a person’s agitation and psychotic symptoms.
