Advances in embryology, genetics and neuroimaging are helping to discern possible correlations between facial structures, brain and personality. A behavior that has been the subject of much research is impulsiveness, where different conceptualizations have arisen with some etiological controversy. Objectifying the possibility of different levels of impulsivity in the face is studied. For an adult sample (N =33), the Novelty Seeking dimension of Temperament and Character-Revised by Cloninger, the Barratt Impulsiveness Scale (BIS-11) and Impulsiveness Scale State (EIE) were used. In the forehead the degree of inclination front to back was measured, resulting in a positive association with the 3 psychometric scores. Three judges evaluated the level of inclination of the forehead, resulting in a high reliability and a high correlation with the objective measurement of inclination. Although the sample is small, the data provides an objective approach to the study of the variable analyzed.
