This article extends the study of judged similarity among kinship terms from consanguineal to step- terms. Based on a sample of college students, it presents a Euclidean representation of American kinship terms that shows that the distinction between consanguineal terms and step- terms is crucial. This representation matches predictions from the componential analysis paradigm and is shared by respondents of both genders with different ethnicities and first languages spoken.
