This experimental study tested whether exposure to female centerfold images causes young adult males to believe more strongly in a set of beliefs clinical psychologist Gary Brooks terms "the centerfold syndrome." The centerfold syndrome consists of five beliefs: voyeurism, sexual reductionism, masculinity validation, trophyism, and nonrelational sex. Past exposure to objectifying media was positively correlated with all five centerfold syndrome beliefs. Recent exposure to centerfolds interacted with past exposure to predict three of the five centerfold syndrome beliefs. Recent exposure to centerfolds had immediate strengthening effects on the sexual reductionism, masculinity validation, and nonrelational sex beliefs of males who view objectifying media less frequently. These effects persisted for approximately 48 hours.
