概括
本研究引入香烟购买任务时间 (CPT-T) 来衡量时间成本如何影响香烟需求. 结果表明,日益增加的时间延迟减少了需求,类似于货币成本,验证了CPT-T作为一个有用的工具.
科学领域:
- 行为经济学是一种行为经济学.
- 药物成科学 药物成科学
- 心理药理学 心理药理学
背景情况:
- 传统的香烟购买任务 (CPT) 评估基于货币成本的需求.
- 时间作为消费决策成本的作用经常被忽视.
- 引入了一种新型措施,即购买香烟的任务时间 (CPT-T),以评估需求作为时间成本的函数.
研究的目的:
- 引入和验证卷烟购买任务时间 (CPT-T) 作为对卷烟需求的衡量标准.
- 调查时间成本对香烟消费的影响.
- 评估CPT-T的特异性和歧视性有效性.
主要方法:
- 实验1:参与者 (N=50) 在假设的延迟条件下完成了标准CPT.
- 实验2:参与者 (N=50) 通过延迟完成了CPT-P,通过货币条件完成了CPT-T.
- 实验3:使用CPT-T比较吸烟者 (n=50) 和非吸烟者 (n=50) 之间对香烟,芯片和纸的需求.
主要成果:
- 随着时间延迟的增加,需求强度下降,证实时间是成本.
- 时间和货币成本的增加减少了需求强度和断点,与需求定律保持一致.
- 吸烟者对香烟的需求高于非吸烟者;吸烟者优先考虑香烟和纸,而不是芯片,这表明感知到的基本性.
结论:
- 时间作为增强剂需求的成本,包括香烟.
- CPT-T是一个有效和具体的措施,用于评估由时间成本影响的香烟需求.
- 这些发现支持新的理论框架,以了解与强化器病理学相关的物质使用障碍.

Chronic Obstructive Pulmonary Disease-IV: Assessement and Diagnostic Studies
Assessing and diagnosing Chronic Obstructive Pulmonary Disease (COPD) involves a detailed approach that includes a comprehensive review of medical history, physical examination, and a variety of diagnostic tests. This thorough evaluation is essential to ensure an accurate diagnosis and guide effective management strategies.

Pulmonary Function Tests
Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
