Cognitive Dissonance01:38

Cognitive Dissonance

36.8K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Design of Transmission Shafts - Stress Analysis

724
Designing a transmission shaft requires a thorough understanding of the stresses induced by bending moments and torques, especially in systems where power is transferred through gears. These forces create force-couple systems at the centers of the shaft's cross-sections, leading to both transverse and torsional loading. Although shearing stresses from transverse loads are typically smaller than those from torques and are often overlooked, the significant normal stresses from these loads...

Group Design

10.3K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Factorial Design02:01

Factorial Design

13.7K
Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...

Language and Cognition01:27

Language and Cognition

745
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Cognitive Therapy01:25

Cognitive Therapy

945
Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

Area of Science:

  • Medical Education
  • Surgical Simulation
  • Gastroenterology

Background:

  • Endoscopic submucosal dissection (ESD) training faces instructor shortages in Western countries.
  • Surgical simulators offer a potential solution to augment ESD training.
  • Cognitive task analysis (CTA) is a validated method for improving healthcare training programs.

Purpose of the Study:

  • To apply a CTA-based approach to identify cognitive aspects of ESD performance.
  • To generate qualitative insights for enhancing ESD training.

Main Methods:

  • Utilized CTA framework for semi-structured interviews with ESD practitioners (4 experts, 4 novices).
  • Conducted three observations of expert ESD trainers during procedures or workshops.
  • Analyzed interview and observation data for qualitative themes and relationships.

Main Results:

  • Identified thematic insights across four cognitive categories: learning goals/principles, challenges/concerns, strategies, and decision-making.
  • Mapped specific insights to various tasks within the ESD procedure.
  • Revealed cognitive themes crucial for effective ESD training.

Conclusions:

  • CTA successfully identified cognitive themes related to ESD procedural tasks.
  • Qualitative insights can inform the design of ESD training systems, including virtual reality simulators.
  • This approach supports the development of effective training tools for endoscopic submucosal dissection.
