Prediction Intervals01:03

Prediction Intervals

3.3K
The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Timing and Consequences on Behavior01:08

Timing and Consequences on Behavior

354
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective. 
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

The Anchoring-and-Adjustment Heuristic

7.7K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Decision Making: P-value Method

6.8K
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim  is also stated. These statements can act as null and alternative hypotheses:  a null hypothesis would be a neutral statement while the alternative hypothesis can...

Pharmacokinetic Models: Comparison and Selection Criterion01:26

Pharmacokinetic Models: Comparison and Selection Criterion

334
Physiological and compartmental models are valuable tools used in studying biological systems. These models rely on differential equations to maintain mass balance within the system, ensuring an accurate representation of the dynamic processes at play.
Physiological models take a detailed approach by considering specific molecular processes. They can predict drug distribution, metabolism, and elimination changes, providing a comprehensive understanding of how drugs interact with the body.

The Availability Heuristic01:08

The Availability Heuristic

6.9K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

  • 神经科学是一个神经科学.

背景情况:

  • 延迟折扣模型评估对延迟后果的敏感性.
  • 超波形模型引入了"s"参数,以减少人类受试者数据的差异.
  • "s"参数在数学上允许后果和延迟之间的非线性关系,可能反映主观的时间流逝.

研究的目的:

  • 检查与参与者的基于时间的经验相关的超波形's'的概念证明.
  • 调查"s"参数是否与时间估计和时间距离估计的准确性相关.
  • 探索"s"参数的概念价值,以计算时间感知在主体层面的差异.

主要方法:

  • 211名成年人参与了一个众包样本.
  • 参与者完成了时间估计任务 (持续时间判断).
  • 参与者完成了时间距离估计任务 (主观延迟感知).

主要成果:

  • 参与者普遍低估了过期的持续时间.
  • 收入和日制折扣任务,但不是超波罗的"s",与时间估计的准确性有很大关系.
  • 参与者的年龄和延迟框架,但不是超波罗的"s",与时间距离估计差异显著相关.

结论:

  • 超波罗形's'参数可能无法解释在本研究中测量的时间估计中的个体差异.
  • 拉希林"s"的适度效果表明,在解释主观时间差异时,概念价值有限.
  • 需要进一步研究以了解"s"参数在受试者级别时间感知变化中的作用.
