Schemas

12.1K
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.

Social Traps01:41

Social Traps

23.8K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Naturalistic Observations

16.4K
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 Cell Cycle Control System02:11

The Cell Cycle Control System

12.7K
The cell cycle is an organized set of events that leads the cell to divide into two daughter cells, each containing chromosomes identical to the parent cell. It is the cell cycle that leads to the formation of an entire organism from a single-cell zygote. Besides, cell division also functions in the renewal or repair of tissues in adult multicellular eukaryotes. For example, in the bone marrow, the stem cells divide to form new blood cells. Although essential for several functions, cell...

Bystander Effect02:09

Bystander Effect

9.7K
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.

Summary

Protected cycle lanes make cyclists feel safer, but may lead to higher speeds. Further research is needed to understand if this impacts overall road safety for active transport.

Area of Science:

  • Transportation science
  • Human factors engineering
  • Urban planning

Background:

  • Low cycling rates are often linked to safety concerns.
  • Protected cycle lanes are proposed to improve cyclist safety.
  • Existing research on their effectiveness is conflicting.

Purpose of the Study:

  • To investigate cyclists' perceptions and speeds in protected vs. unprotected cycle lanes.
  • To understand factors influencing cyclist behavior and safety in different infrastructure.
  • To inform the design of safer active transport environments.

Main Methods:

  • Two studies were conducted: an online questionnaire with video clips and an on-road experiment.
  • Cyclists' perceptions of safety, difficulty, and attentional demand were assessed.
  • Cyclists' speeds were measured in protected lanes, unprotected lanes, and streets without cycle lanes.

Main Results:

  • Cyclists reported feeling safer and less concerned about hazards in protected cycle lanes.
  • There was no evidence of reduced attentional demand in protected lanes.
  • Higher maximum cycling speeds were observed in protected cycle lanes.

Conclusions:

  • Protected cycle lanes enhance perceived safety and willingness to cycle.
  • Increased speeds in protected lanes warrant further investigation regarding actual safety outcomes.
  • Optimizing protected cycle lane design requires balancing perceived safety with speed management.
