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

743
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...

Framing Effects

7.9K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Hypothesis: Accept or Fail to Reject?

29.4K
The outcome of any hypothesis testing leads to rejecting or not rejecting the null hypothesis. This decision is taken based on the analysis of the data, an appropriate test statistic, an appropriate confidence level, the critical values, and P-values. However, when the evidence suggests that the null hypothesis cannot be rejected, is it right to say, 'Accept' the null hypothesis?
There are two ways to indicate that the null hypothesis is not rejected. 'Accept' the null...

Principle of Impulse and Moment01:15

Principle of Impulse and Moment

514
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.

Summary

Acceptance and Commitment Therapy (ACT) effectively reduced psychological symptoms and impulsive behaviors in adults. While ACT improved psychological flexibility and distress tolerance, it did not significantly alter delay discounting, contrasting prior findings.

Area of Science:

  • Psychology
  • Clinical Psychology
  • Behavioral Science

Background:

  • Impulsive decision-making is a transdiagnostic issue across various psychological disorders.
  • Acceptance and Commitment Therapy (ACT) shows promise in addressing psychological inflexibility and distress.
  • Understanding ACT's impact on impulsive behaviors is crucial for developing effective interventions.

Purpose of the Study:

  • To investigate the transdiagnostic efficacy of Acceptance and Commitment Therapy (ACT) in reducing impulsive decision-making.
  • To assess ACT's effects on psychological symptoms, valued living, delay discounting, psychological flexibility, and distress tolerance.
  • To compare ACT's outcomes against an inactive control group in a community sample.

Main Methods:

  • A randomized controlled trial involving 40 adults assigned to either ACT or an inactive control group.
  • Eight individual sessions of ACT were administered.
  • Multilevel modeling of growth curves was used to analyze pre-, mid-, and post-assessment data.

Main Results:

  • Significant improvements were observed in psychological flexibility, distress tolerance, and psychological symptoms for the ACT group.
  • The ACT group showed a greater reduction in problem behavior compared to the control group.
  • No significant changes were found in delay discounting tasks or the progress subscale of valued living.

Conclusions:

  • Acceptance and Commitment Therapy (ACT) demonstrates potential as a transdiagnostic treatment for impulsive behaviors.
  • ACT positively impacts psychological flexibility and distress tolerance, contributing to behavioral change.
  • The observed lack of effect on delay discounting warrants further investigation and contrasts with some previous research.
