Resumen
La seguridad de los peatones es desigual, con personas negras, masculinas y visiblemente inseguras que enfrentan mayores riesgos. El comportamiento de rendimiento del conductor está influenciado por las acciones de los peatones y la demografía, lo que pone de relieve la necesidad de intervenciones de seguridad específicas.
Área de la Ciencia:
- Planificación urbana y seguridad en el transporte.
- Sociología y disparidades de salud pública.
- Ciencias del comportamiento y análisis de riesgos.
Sus antecedentes:
- La seguridad de los peatones es un gran desafío urbano con importantes disparidades sociodemográficas en las muertes.
- Comprender los comportamientos de los peatones y los conductores es crucial para abordar estas desigualdades de seguridad.
Objetivo del estudio:
- Investigar cómo los atributos individuales, el contexto social y las condiciones ambientales influyen en los comportamientos de los peatones que cruzan y los conductores que ceden.
- Identificar los factores que contribuyen a las disparidades en los resultados de la seguridad de los peatones.
Principales métodos:
- Análisis de más de 1.000 horas de imágenes de video de dos intersecciones urbanas.
- Anotación manual de los cruces de peatones y las interacciones de los vehículos.
- Estimación de modelos binarios de logit para cruces de peatones no conformes (NCPC) y conductores inflexibles (DUY).
Principales resultados:
- Hombres, negros y peatones inseguros visiblemente alojados, así como aquellos que cruzan solos o corriendo, exhiben tasas más altas de cruces no conformes y menor rendición del conductor.
- El incumplimiento de los peatones es el predictor más fuerte de la inflexibilidad del conductor.
- La inflexibilidad del conductor es más común durante las horas de la mañana, con vehículos personales y hacia peatones más viejos, negros / marrones o visiblemente inseguros.
Conclusiones:
- Las intervenciones para la seguridad de los peatones deben abordar factores sociales y de comportamiento, incluida la marginación y el contexto.
- Los hallazgos apoyan la equidad en el transporte al revelar cómo los factores sociales moldean el riesgo.
- Las intervenciones deben extenderse más allá de la infraestructura para incluir educación, reducción de sesgos e iniciativas comunitarias.

02:30Naturalistic 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...

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 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...

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...

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.

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.
