Summary
This review explores impulsivity, examining its definitions, neurochemical underpinnings (serotonin, dopamine), and links to timing and aggression. It highlights how factors like reward delay and cognitive functions influence impulsive behavior.
Area of Science:
- Neuroscience
- Behavioral Psychology
- Psychiatry
Background:
- Impulsivity is a complex trait with varied definitions and significant implications across disciplines.
- Understanding the neurobiological and cognitive factors contributing to impulsivity is crucial for developing effective interventions.
Purpose of the Study:
- To comprehensively review the current literature on impulsivity.
- To explore the neurochemical basis, cognitive correlates, and measurement of impulsivity.
Main Methods:
- Literature review of scientific articles on impulsivity.
- Examination of neurotransmitter roles (serotonin, dopamine).
- Analysis of cognitive functions (working memory, attention, self-control) and their relation to impulsivity.
Main Results:
- Impulsivity is influenced by serotonin and dopamine neurotransmission.
- Timing, aggression, reward delay, and value discounting are key experimental considerations.
- Working memory, attention, and emotional regulation play significant roles in modulating impulsive behavior.
Conclusions:
- Impulsive behavior arises from a complex interplay of multiple neurobiological and cognitive mechanisms.
- Accurate measurement of impulsivity in both animal models and human studies is essential for understanding decision-making processes.

01:37Reason and Intuition
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the brain can only use...
01:30Attention-Deficit/Hyperactivity Disorder
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.

01:25Self-Regulation
Self-regulation, also known as self-control, encompasses a range of cognitive and behavioral processes that allow individuals to adjust their internal states and outward actions to align with socially acceptable norms and long-term goals. It plays a fundamental role in adaptive functioning, from resisting impulsive behaviors to persisting through challenging tasks. While its benefits are widely recognized, self-regulation is not limitless. Muraven and Baumeister's theory posits that...
01:28Obsessive-Compulsive Disorder
Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...
01:25Borderline Personality Disorder
Borderline Personality Disorder is a complex and multifaceted mental health condition characterized by pervasive instability in interpersonal relationships, self-image, emotions, and impulse control. This instability manifests in extreme emotional reactions, fear of abandonment, and self-destructive behaviors. The disorder significantly impacts daily functioning, often leading to distress in both personal and professional domains.

01:29Introspection
Introspection, long upheld as a reliable route to self-knowledge, involves examining one's thoughts, emotions, and mental processes. It underpins many psychological practices, from mindfulness meditation to psychotherapy and self-help strategies. However, empirical evidence challenges the accuracy of introspection as a means of understanding oneself.Limitations of Introspective InsightSeminal work by Nisbett and Wilson demonstrated that individuals are frequently unaware of the true causes...
