What behavior is characterized by impulsive actions that lack examination of motives?

The behavior characterized by impulsive actions that lack examination of motives is best captured by the concept of impulsivity. Individuals exhibiting impulsivity tend to act on desires or urges without forethought or consideration of consequences, which aligns with the definition provided in the question.

While the psychopathic personality may include impulsive behaviors, it is more specifically characterized by a broader set of traits, including lack of empathy, superficial charm, and manipulativeness, rather than solely impulsivity. Therefore, while psychopathy can manifest impulsive actions, it involves a more complex web of behaviors and motivations.

In contrast, extraversion refers to sociability and assertiveness, and neuroticism involves emotional instability and anxiety, neither of which directly encapsulates the concept of acting impulsively without consideration of motives. Thus, impulsivity is distinctly the behavior that matches the description provided in the question.
