These "cheesecake rats" were quicker to act on visual cues (indicative of impulsivity) but showed more conservative choices in gambling tasks, opting for smaller, safer rewards.Read More

Using data from 1,676 participants, researchers identified a general impulsivity factor, I, which effectively predicts impulsive behaviors. They developed the Adjustable Impulsivity Scale (AIMS) for precise measurement. Findings enhance understanding and measurement of impulsivity.Read More

Through a study on rats, they discovered that impulsivity predicts cocaine consumption not through dopamine production capacity but possibly through the control of its release.Read More
