Summary
This study defines normal bodily urges, crucial for understanding impulse-control disorders. It compares these urges to the urge to tic in Tourette syndrome, identifying areas for future research.
Area of Science:
- Neurobiology
- Psychiatry
- Behavioral Science
Background:
- Understanding the neurobiological basis of urges is key for treating impulse-control disorders.
- Interoceptive urges are normal bodily sensations that prompt action.
Purpose of the Study:
- To characterize the features of normal bodily urges.
- To compare these urges with the urge to tic in Tourette syndrome.
- To identify areas for further investigation into urge phenomena.
Main Methods:
- Phenomenological characterization of interoceptive urges.
- Comparative analysis with patient-reported urges in Tourette syndrome.
Main Results:
- Normal bodily urges involve awareness of sensation, urgency, distress upon delay, temporary suppression, relief after action, and survival association.
- Key differences and similarities between bodily urges and the urge to tic were identified.
Conclusions:
- Characterizing normal urges provides a framework for understanding pathological urges.
- Further research is needed to elucidate the neurobiological underpinnings and clinical implications of urge phenomena.

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

01:29Instinct Theory

Instinct theory proposes that innate biological instincts, like animal behavioral patterns, primarily drive human behavior. These instincts are inborn, not learned, and are fundamental to decision-making and action. Just as animals rely on instincts for critical survival functions such as migration, nest building, and defense, humans are also believed to exhibit behaviors rooted in evolutionary needs. For example, the instinct to reproduce motivates sexual behavior, while territorial instincts...

Primary motives such as sleep, sex, and pain avoidance are crucial drivers of behavior in humans and animals. These motives ensure survival, reproductive success, and overall well-being by prompting actions that meet essential bodily needs.
Sleep is a fundamental physiological drive that fosters a state of restfulness crucial for several bodily functions. It facilitates body restoration, the process by which the body repairs, rejuvenates, and maintains itself during sleep, including memory...

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...

Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.
