概括
驾驶时使用手机,特别是在环形交叉路口,会增加车祸的风险. 分散注意力的年轻司机,特别是使用手机的男性,显示安全边际减少,尽管有些人表现出风险补偿.
科学领域:
- 交通安全研究 交通安全研究
- 驾驶过程中的人类因素
- 道路几何学和事故分析
背景情况:
- 旋转带来复杂的驾驶挑战,增加了事故风险.
- 手机的分心显著加剧了这些风险,尤其对年轻的司机来说.
- 道路几何形状,驾驶状态和驾驶员特征对复合风险的综合影响尚未得到充分研究.
研究的目的:
- 在手机分散注意力的情况下,在圆形路口接受差距时调查碰撞风险.
- 分析道路几何形状,驾驶状态 (手机使用) 和驾驶员特征之间的相互作用.
- 了解分心场景中的安全边缘和驾驶员异质性.
主要方法:
- 使用CARRS-Q驾驶模拟器与32名持驾照的年轻驾驶员进行了测试.
- 在三种电话条件下检查了差距接受场景:基线,手持和自由手.

01:42Schemas

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

01:25The 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...

01:15Assumptions of Survival Analysis

Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.
