Summary
Impulsive traits are linked to problematic internet use (PIU) and smoking in young adults. Specific impulsivity dimensions predict PIU and smoking, suggesting shared mechanisms in addictive behaviors.
Area of Science:
- Psychology
- Neuroscience
- Public Health
Background:
- Problematic Internet Use (PIU) is a growing mental health concern.
- PIU shares similarities with substance use disorders, but underlying mechanisms are not fully understood.
Purpose of the Study:
- To investigate the relationship between specific impulsive traits and PIU.
- To explore the association between impulsive traits and cigarette smoking behaviors in young adults.
Main Methods:
- Two independent samples of university students (N1=1281, N2=1034) were assessed over 3 years.
- Multiple impulsivity measures were used: Barratt Impulsiveness Scale-11 (BIS-11), UPPSP Impulsive Behaviors Scale (UPPSP), and Delay-discounting Test (DDT).
- Logistic regression models analyzed the predictive relationships.
Main Results:
- BIS-11 Attentional Impulsiveness positively predicted both PIU and cigarette smoking across samples.
- BIS-11 Motor Impulsiveness, UPPSP Lack of Perseverance, Lack of Premeditation, and Negative Urgency predicted PIU.
- UPPSP Sensation Seeking uniquely predicted cigarette smoking.
Conclusions:
- Specific dimensions of impulsivity are concurrently implicated in PIU and cigarette smoking.
- These findings highlight potential shared trait markers for addictive behaviors in young adults.

21.4K
According to Newton’s second law of motion, the rate of change of the momentum of an object is the net external force acting on it. The total change in momentum between two timepoints thus depends on both the external force acting on it and the time over which it acts. Describing this mathematically, the total change of an object’s motion is proportional to the force vector and the time over which it is applied. This product is called impulse.
Additionally, it can be shown that the...

The impulse response is the system's reaction to an input impulse. In an RC circuit, the voltage source is the input, and the capacitor's voltage is the output. The system's state and output response before and after input excitation are distinctly defined.
Kirchhoff's law forms an input signal equation, with the capacitor's current and voltage providing the output. Substituting the current and dividing by RC yields a differential equation. The output for an impulse input is the impulse...

When one considers a rigid body undergoing a plane motion, which is essentially a blend of translational and rotational movement, the application of Newton's second law gives the formula for the translational movement of such a body. If this equation is multiplied by a time interval, dt, and then integrated over the limits of integration, it results in an equation that embodies the principle of linear impulse.

The total change in the motion of an object is proportional to the total force vector acting on it and the time over which it acts. This product is called impulse, a vector quantity with the same direction as the total force acting on the object.
By writing Newton's second law of motion in terms of the momentum of an object and the external force acting on it, and simultaneously using the definition of the impulse vector, it can be shown that the total impulse on an object is equal to its...

The angular impulse and momentum principle provides insights into how forces applied at a distance from an object's rotational axis influence its angular velocity. It builds upon the crucial relationship between the moment of force and angular momentum. By integrating this equation, substituting the limits for the initial and final times, a comprehensive expression representing the angular impulse and momentum principle is derived.
