Schemas

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.

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.

The Anchoring-and-Adjustment Heuristic

7.2K
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...

Hindsight Biases

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Naturalistic Observations

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...

Area of Science:

  • Cardiology
  • Oncology
  • Gastroenterology

Background:

  • Myocardial infarction (MI) is a leading global cause of death.
  • Malignant neoplasms are the second leading cause of death.
  • Concomitant MI and cancer increase mortality risk; bleeding complications can reveal occult cancers.

Observation:

  • An 81-year-old male presented with acute MI, undergoing percutaneous intervention (PCI).
  • The patient developed early post-stenting hemorrhagic complications.
  • Two concomitant malignant neoplasms were identified as the cause.

Findings:

  • Favorable acute-phase outcome despite de-escalation therapy and high intrastent thrombotic risk.
  • Hemorrhagic complications in acute MI patients warrant investigation for neoplastic causes.
  • Digestive cancers are frequently implicated, but other sites should be considered.

Implications:

  • Early detection of occult cancers in MI patients through bleeding event investigation.
  • Tailored diagnostic strategies based on bleeding source are essential.
  • Improved patient management by addressing both cardiovascular and oncological emergencies.
