Book excerpt: Nancy Caro Hollander profiles ten Argentine, Chilean, and Uruguayan psychologists and psychoanalysts who experienced firsthand, and later strove to comprehend, the political and social oppression that occurred under the military dictatorships in their countries during the 1970s and 1980s. She recounts how psychoanalysts employed what she calls "liberation psychology" to understand the brutal trauma suffered by the populace under fiercely repressive regimes and then to help themselves and others to confront and overcome a culture of intimidation, coercion, torture, and, frequently, murder.
