Metnin bütünüyle birlikte değerlendirilmeli ama yukarıda tartışma bölümündeki açıklamanız bana bu terimi düşündürdü.

Şu da kısa bir açıklaması:
Impulsivity (or impulsiveness) is a multifactorial construct that involves a tendency to act on a whim, displaying behavior characterized by little or no forethought, reflection, or consideration of the consequences. Impulsive actions are typically "poorly conceived, prematurely expressed, unduly risky, or inappropriate to the situation that often result in undesirable consequences," which imperil long-term goals and strategies for success. A functional variety of impulsivity has also been suggested, which involves action without much forethought in appropriate situations that can and does result in desirable consequences. "When such actions have positive outcomes, they tend not to be seen as signs of impulsivity, but as indicators of boldness, quickness, spontaneity, courageousness, or unconventionality" Thus, the construct of impulsivity includes at least two independent components: first, acting without an appropriate amount of deliberation, which may or may not be functional; and second, choosing short-term gains over long-term ones.

Hiperaktivite/dikkat eksikliği konusundaki çeşitli kaynaklarda ataklık ile dürtüsellik aynı anlamda kullanılmış. Bu da beni "impulsivity" teriminin ataklığı tam olarak karşıladığına ikna etti.
