Hindsight Biases

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?

Cognitive Learning

Cognitive Learning

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Principles of Classical Conditioning

Principles of Classical Conditioning

Classical conditioning, as described by Ivan Pavlov, is a foundational concept in associative learning, where a neutral stimulus becomes capable of eliciting a conditioned response through association with an unconditioned stimulus. The process of acquisition, where this learning occurs, and the subsequent phenomena of contiguity, contingency, generalization, discrimination, extinction, and spontaneous recovery are crucial for a comprehensive understanding of classical conditioning.
During the...

Avoidance Learning and Learned Helplessness

Avoidance Learning and Learned Helplessness

Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

Behaviorism

Behaviorism

The field of behaviorism was pioneered by figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner fundamentally shifted the focus of psychology to the observable and controllable aspects of human and animal behavior. This shift marked a critical evolution in the discipline, emphasizing scientific rigor and experimental methodology.
The core premise of behaviorism is its focus on observable behavior rather than internal thoughts or feelings. This approach argues that true scientific...

Purposive Learning

Purposive Learning

E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a...

Summary

Post-tonsillectomy bleeding is a significant risk, especially in younger children. Overnight observation is recommended after any bleeding episode due to increased risk of severe recurrence.

Pediatric Surgery
Public Health

Background:

A 2007 consensus paper addressed life-threatening post-tonsillectomy hemorrhage risks in children.
This led to a nationwide multicenter study assessing tonsil and adenoid surgeries.

Purpose of the Study:

Evaluate the incidence and severity of postoperative hemorrhage after tonsillectomy, tonsillotomy, and adenoidectomy.
Analyze risk factors and outcomes, including the need for surgical revision.

Main Methods:

A 9-month prospective study assessed consecutive tonsillectomies, tonsillotomies, and adenoidectomies in Austrian public hospitals.
Data collected via online questionnaire included patient demographics, surgical details, and postoperative bleeding events graded by severity.

Main Results:

The study included 6,765 patients (tonsillectomy 31%, tonsillotomy 19%, adenoidectomy 50%).
Postoperative hemorrhage occurred in 15% after tonsillectomy and 2.3% after tonsillotomy, increasing with age.
Surgical revision was needed in 4.2% of tonsillectomy patients and 0.9% of tonsillotomy patients.

Conclusions:

Tonsillotomy has increased in younger children following 2007 guidelines.
Overnight hospital admission is advised for all postoperative hemorrhage cases due to a doubled risk of severe re-bleeding after a minor event.
