Summary
Learner personality, particularly Extraversion, impacts surgical skill acquisition when instructors perceive trainees as trainable. Instructor perceptions and learner traits are crucial for effective surgical training and feedback.
Area of Science:
- Medical Education
- Surgical Skills Training
- Psychology in Medicine
Background:
- Learner variability in surgical skill acquisition is significant despite uniform training.
- Learner personality traits may influence skill acquisition independently.
- Instructor perceptions and feedback dynamics are critical in surgical training.
Purpose of the Study:
- To investigate the association between learner personality and surgical skill acquisition (performance improvement).
- To explore the interaction between instructor perceptions of trainability and learner personality.
- To understand how these factors influence surgical training and feedback.
Main Methods:
- Prospective, two-phase study with 62 undergraduate students (medical and non-medical).
- Participants performed an end-to-side anastomosis on a model over two sessions with expert feedback.
- Assessed learner personality, performance improvement, and instructor perceptions of trainability.
Main Results:
- A significant interaction was found between learner Extraversion and instructor-perceived trainability (OR=4.83, p=0.017).
- Higher Extraversion correlated with improved performance only in those deemed trainable.
- Trainable participants received significantly less feedback (9.45) than non-trainable ones (16.48).
Conclusions:
- Both individual learner characteristics and instructor perceptions are vital for successful surgical skill acquisition.
- The interplay between personality and perceived trainability affects training outcomes.
- Feedback delivery may differ based on instructor perceptions of learner trainability.

01:30Social Cognitive Perspective on Personality
698
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

01:29Theory of Attribution II: Kelley's Covariation Theory

Attribution theory plays a crucial role in social psychology, helping to explain how individuals interpret the causes of behavior. One prominent model within this field is Harold Kelley's covariation theory, which provides a systematic approach to determining whether internal traits or external circumstances drive a person's actions. The model posits that individuals rely on three key types of information—consensus, consistency, and distinctiveness—to make these judgments.Consensus:...

The nursing process provides a clinical decision-making framework for patients and families to establish and implement a personalized care plan. Since part of the nurse's duties is to teach patients, the steps of the nursing process are the most effective way to approach instruction. The nursing process and the teaching-learning process are inextricably linked.

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...

01:24Sources of Self-Esteem II: Performance Feedback

Self-esteem is intricately tied to our perception of competence and our ability to exert control over our lives. One of the primary sources of this perception is performance feedback — the ongoing evaluation of our actions in terms of success and failure. According to Franks and Marolla (1976), people derive self-worth from experiencing themselves as causal agents, capable of achieving goals and overcoming obstacles. This process nurtures a critical component of self-esteem:...

01:29Dark Triad and Person Perception

Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et...
