This study of 24 hospitalized adolescent delinquents revealed that the delinquents were well aware of their impulsivity. This awareness was related not to age, sex, race, police contact, or incarceration but to objective measures of impulsivity. In some impulsive delinquents, internal awareness of their intrapsychic inability to control and modulate impulses was blocked and was projected onto the outside world; it was experienced as a feeling of doom or helplessness about the future.Abstract Teaser
