Heredity, color vision, and alcoholism

Ninety-two Cree individuals were tested with the Farnsworth-Munsell 100-Hue Test (FM = 100). Information concerning racial membership, age, sex, and drinking behavior was collected. High error scores (for the FM-100) were found in this Cree population. Alcoholic individuals (both abstinent and nonabstinent) had higher error scores than a comparable population of nonalcoholic Cree individuals from the same population. Implications concerning the etiology of alcoholism are discussed.
