To explore gender-, and age-related differences on locus of control orientation, the Levenson's Tri-factorial Scale was administered to a 1200-male/female Brazilian subjects sample within a 17-to-56 age range. Anova 2X7 found out a main effect due to gender on the "Powerful Others" factor, men scoring higher than women. Reliable age differences were observed at the level of internality factor when scoring for "Total Internality". Generally speaking, internality increased with age.
