まとめ
歩行者の安全性は不平等で,黒人,男性,および目に見える住宅の不安定な個人がより高いリスクに直面しています. ドライバーの譲歩行動は,歩行者の行動と人口統計によって影響を受け,ターゲットを絞った安全対策の必要性を強調しています.
科学分野:
- 都市計画と交通の安全性
- 社会学と公衆衛生の格差 社会学と公衆衛生の格差
- 行動科学とリスク分析
背景:
- 歩行者の安全は都市における大きな課題であり,死亡者数には社会統計学的差が大きい.
- 歩行者と運転者の行動を理解することは,これらの安全不平等に対処するために不可欠です.
研究 の 目的:
- 個々の属性,社会的文脈,環境条件が,歩行者交差点やドライバーの許容行動にどのように影響するかを調査する.
- 歩行者の安全に関する結果の格差に寄与する要因を特定する.
主な方法:
- 2つの都市交差点からの1,000時間以上のビデオ映像の分析.
- 歩行者横断路と車両の相互作用に関する手動の注釈.
- 非準拠の歩行者横断 (NCPC) とドライバーの不屈 (DUY) のバイナリロギットモデルの推定.
主要な成果:
- 男性,黒人,目に見える不安全な歩行者を収容するだけでなく,単独で横断したり走ったりする人は,不適切な横断の割合が高く,ドライバーの降伏率が低い.
- 歩行者の不服従は,ドライバーの不屈の最も強い予測要因です.
- ドライバーの不屈は,朝の時間,個人用車,そして年寄り,黒人/茶色人,または目に見える不安全な歩行者に対してより一般的です.
結論:
- 歩行者の安全への介入は,疎外と文脈を含む社会的および行動的要因に対処する必要があります.
- 調査結果は,社会的要因がリスクをどのように形作るかを明らかにすることによって,輸送の公平性を支持しています.
- 介入はインフラストラクチャを超えて,教育,バイアス削減,コミュニティイニシアチブを含むべきである.

Naturalistic Observations
17.8K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Bystander Effect

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.

Observational Studies

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Cross-Sectional Research
12.7K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Surveys
17.1K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Schemas
12.4K
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.
