Final answer:
Common characteristics of antisocial personality disorder include a lack of remorse, superficial charm, and impulsivity, while conformity and sincerity are generally not associated with this disorder.
Step-by-step explanation:
The characteristics that are common in people with antisocial personality disorder (ASPD) include a lack of remorse, superficial charm, and impulsivity. Individuals with ASPD don't typically display conformity or sincerity; rather, they may exhibit behaviors that are in direct opposition to societal norms and may manipulate or harm others without feeling guilty. Additionally, their charm is often superficial, used as a means to deceive or exploit others for personal gain. Impulsivity is another hallmark trait, characterized by the tendency to act on whim without considering consequences.
People with high levels of psychoticism, which is related to ASPD, tend to be nonconformists and impulsive, as noted by Eysenck, Eysenck & Barrett (1985). This dimension contrasts with high superego control, which is associated with high impulse control and prosocial behaviors. Thus, an understanding of impulsivity and a lack of remorse within the context of personality disorders is critical when studying antisocial personality disorder.
