概括
药物对冲动选择的影响各不相同,但速率依赖性,即效果取决于基线行为率,有助于解释差异. 这个由彼得·B·杜斯 (Peter B. Dews) 提出的原则在行为药理学中仍然至关重要.
科学领域:
- 行为药理学行为药理学
- 神经科学是一个神经科学.
- 心理药理学 心理药理学
背景情况:
- 药物如何影响冲动行为存在差异.
- 冲动选择可能会受到基线行为水平的影响.
- 彼得·B·杜斯 (Peter B. Dews) 的利率依赖原则为理解这些变化提供了一个框架.
研究的目的:
- 探索速度依赖如何解释兴奋剂和阿片类药物对冲动选择影响的差异.
- 为了确定这些依赖于速率的药物效应背后的行为机制.
- 突出Dews在行为药理学工作的持续相关性.
主要方法:
- 对兴奋剂和阿片类药物和冲动选择的临床前研究的审查.
- 对实验数据的分析药物对强化剂的灵敏度的影响,强化剂的大小和延迟.

Reason and Intuition
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the brain can only use...
The Anchoring-and-Adjustment Heuristic
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 $2,000...
Hindsight Biases
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?
Attribution Theory
Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958). An internal factor is an...
Fundamental Attribution Error
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is called the fundamental attribution...
Personal Choice and Fate Attributions
Some individuals interpret life events as a consequence of their personal choices and actions, while others believe that outcomes are dictated by fate or destiny. This divergence in perspective has been examined in psychological and cross-cultural studies, particularly in relation to religious faith and cultural beliefs about causality.Fate and Personal ResponsibilityPeople who emphasize personal responsibility view events as direct consequences of their decisions. For instance, breaking a leg...
