SANCHEZ-SARMIENTO, PAOLA; GIRALDO-HUERTAS, JUAN JOSÉ  e  QUIROZ-PADILLA, MARÍA FERNANDA. Impulsivity: A view from the behavioral neuroscience and developmental psychology. Av. Psicol. Latinoam. [online]. 2013, vol.31, n.1, pp.241-251. ISSN 1794-4724.

Impulsivity has been linked to three main factors: performing without direct involvement of the frontal lobe functions, an increase in the speed of response, and the acquisition of immediate gratification. This behavioral inhibition deficit involves a variety of behaviors including aspects of hyperexcitability, behavioral disinhibition and higher order decision making. Although by tradition, the definition of this executive function has been conceptualized from a psychopathological view, currently, the wide variety of neuropsychological, developmental and animal models assessment techniques encourage us to establish dialogues that integrate the knowledge of these theoretical perspectives for the interpretation and understanding of impulsivity.
