With the understanding of phobias has come a magic bag of treatments: exposure therapy that can stomp out a lifetime phobia in a single six-hour session; virtual-reality programs that can safely simulate the thing the phobia most fears, slowly stripping it of its power to terrorize; new medications that can snuff the brain’s phobic spark before it can catch.
In the past year, the U. S. Food and Drug Administration approved the first drug—an existing antidepressant.
Most psychologists now assign phobias to one of the three broad categories: social phobias, in which the sufferer feels paralyzing fear at the prospect of social or professional encounters; panic disorders, in which the person is periodically {{U}}blindsided{{/U}} by overwhelming fear for no apparent reason; and specific phobias—fear of snakes and enclosed spaces and heights

Such a "sociodemographic" approach tends to regard assimilation as a benign process, taking for granted increased economic advantages and inevitable cultural integration, in a supposedly egalitarian context. However, this approach fails to take into account the colonial nature of the Puerto Rican case, with this group, unlike their European predecessors, coming from a nation politically subordinated to the United S
