Impulse01:13

Impulse

21.7K
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...

Impulse Response01:17

Impulse Response

750
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...

Mate Choice01:20

Mate Choice

11.8K
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

Principle of Impulse and Moment01:15

Principle of Impulse and Moment

520
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.

Impulse-Momentum Theorem00:49

Impulse-Momentum Theorem

19.4K
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...

Principle of Angular Impulse and Momentum: Problem Solving

525
Consider a ball of mass m, attached to a massless rod of known length, subjected to a time-dependent torque. If the initial velocity of the mass is known, then the final velocity of the mass for time t can be determined using the principle of angular impulse and momentum.
Initially, a free-body diagram of the system is drawn to illustrate all the forces acting upon the system, providing a crucial understanding of the dynamics at play. Then, the principle of angular impulse and momentum is...

Area of Science:

  • Psychology
  • Behavioral Science
  • Neuroscience

Background:

  • Impulsivity is understood as multifaceted, involving motor and cognitive aspects.
  • The interplay and shared psychological resources between these impulsivity subdomains require further investigation.

Purpose of the Study:

  • To investigate impulsivity transfer effects in electronic gambling.
  • To assess the efficacy of harm-minimization strategies in inducing motor cautiousness and influencing cognitive choice.

Main Methods:

  • 70 regular gamblers participated in an electronic slot machine simulation.
  • Interventions included discriminatory motor choice procedures and responsible gambling messages (emotive/non-emotive).
  • Measures included delay discounting (Monetary Choice Questionnaire) and reflection impulsivity (Information Sampling Task).

Main Results:

  • Discriminatory motor choice procedures successfully induced motor cautiousness.
  • Both discriminatory choice and emotive messages improved cognitive choice.
  • Emotive messages did not improve motor response inhibition, indicating distinct pathways for cognitive enhancement.

Conclusions:

  • Structural changes in slot machines promoting active motor engagement can improve gambling decision-making.
  • This active engagement fosters a transfer of cautiousness to broader cognitive domains.
  • Harm-minimization strategies can be tailored to target specific impulsivity subdomains effectively.
