摘要：AbstractWhat do young people think about lying? Does the conception of lie vary among boys and girls and in different stages of adolescent's development? This article attempts to recognize the conceptions of lie in adolescences in terms of gender and school grade, as well as to contribute to strengthening school-family relations by recognizing the factors that promote deception. A questionnaire was applied to 112 Portuguese students, and the evidence collected reveal that although there are situations in which gender differences are notorious, is essentially in school grades and thus age that we note the most significant differences in conceptions of the lie.
