- 心理学 心理学 心理学
- 汽车工程 汽车工程
背景情况:
- 驾驶焦虑会对道路安全和驾驶体验产生负面影响.
- 焦虑是一种高度兴奋的情绪,在姿势和坐姿行为中体现出来.
- 客观地测量驾驶焦虑,对于开发干预系统至关重要.
研究的目的:
- 为了研究驾驶焦虑和坐着时压力分布之间的关系.
- 识别与焦虑水平升高相关的特定驾驶情况.
- 为车载情绪识别和人机交互系统提供数据.
主要方法:
- 30名参与者通过使用标准化音频和倒计时任务来诱导平静 (基线) 和焦虑状态.
- 在八个驾驶条件下使用压力来测量压力分布和重心波动.
- 用自我评估措施 (SAM) 验证了主观焦虑水平,并使用威尔科克森签名等级测试分析了数据.
主要成果:
- 与基线相比,焦虑导致压力分布增加,大腿,部和腰部的摆动增加.
- 包括aTHR_Max和rCOPBTL_Std在内的40个显著特征,将焦虑与平静区分开来,特别是在左腿,右部和腰部.
- 高不确定性/高互动性场景 (例如交通拥堵,圆形交叉路口) 与焦虑有很强的相关性,与可预测的场景 (例如停车) 不同.
结论:
- 坐着压力分布和摇摆模式可以客观地识别驾驶焦虑.
- 特定的驾驶场景,特别是那些带有不确定性的场景,是焦虑的关键触发因素.

Anxiolytic Drugs: Overview
1.3K
Anxiolytic drugs are vital in managing anxiety disorders by effectively alleviating symptoms such as excessive fear, tachycardia, and tremors. There are several classes of anxiolytic medications, each with unique mechanisms of action and potential side effects.
Primary Types of Anxiolytic Drugs
1. Benzodiazepines:
Benzodiazepines bind to the GABA-A receptor in the brain, enhancing GABA's interaction. This action reduces neurotransmission, effectively blocking anxiety-associated limbic...

Anxiolytic Drugs: Benzodiazepines and Buspirone
2.8K
Benzodiazepines are a class of anxiolytic drugs known for their rapid efficacy and high therapeutic-to-lethal dose ratio, but with a potential risk of drug dependence. These drugs are lipophilic, allowing for rapid absorption after oral administration, eventually reaching the central nervous system (CNS). Once in the CNS, benzodiazepines bind to the allosteric site of the GABAA receptor. This binding enhances the inhibitory effects of the neurotransmitter GABA. By doing so, they prevent...
