Fixed Action Patterns01:06

Fixed Action Patterns

17.7K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Heating and Cooling Curves02:44

Heating and Cooling Curves

28.1K
When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

816
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Acid-Base Titration Curves02:23

Acid-Base Titration Curves

141.9K
A titration curve is a plot of some solution property versus the amount of added titrant. For acid-base titrations, solution pH is a useful property to monitor because it varies predictably with the solution composition and, therefore, may be used to monitor the titration’s progress and detect its endpoint. Acid-base titration can be performed with a strong acid and a strong base, a strong acid and a weak base, or a strong base and a weak acid.
For a titration carried out for 25.00 mL of...

Avoidance Learning and Learned Helplessness

2.7K
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...

Irritable Bowel Syndrome I: Introduction01:17

Irritable Bowel Syndrome I: Introduction

1.2K
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...

Area of Science:

  • Medical Education
  • Surgical Simulation
  • Surgical Skills Training

Background:

  • Simulation-based training is crucial for cost-effective surgical education.
  • Ex vivo animal models offer a realistic platform for learning complex procedures.
  • Understanding learning curves accelerates skill acquisition in surgical residents.

Purpose of the Study:

  • To describe the learning curves associated with simulation-based laparoscopic small bowel anastomosis.
  • To identify variables that can accelerate the learning process in surgical training.

Main Methods:

  • Twenty general surgery residents performed laparoscopic jejuno-jejunal anastomoses (JJA) and gastro-jejunal anastomoses (GJA) on swine models.
  • A structured instructional design (ID) incorporated didactic materials, hands-on practice, and feedback.
  • Performance was assessed by procedure time and anastomotic leak occurrence.

Main Results:

  • Proficiency was achieved after approximately 24 procedures for both GJA and JJA.
  • Four distinct learning curve patterns (exponential, rapid, slow, no tendency) were identified.
  • The learning curve pattern could be predicted after the eighth procedure.

Conclusions:

  • Early identification of learning curves aids in estimating training duration and readiness for patient procedures.
  • This method helps identify individuals lacking innate technical skills.
  • Standardized instructional design enables effective learning strategy assessment and comparison.
