Professional Values01:29

Professional Values

10.7K
Nurses are responsible for caring for patients during birth, death, illness, and healing. Professional values guide the decisions and actions that nurses make in their careers. If nurses know the decisions and actions to take, providing patients with exceptional care is possible.
The values that are the foundation of the nursing profession are altruism, autonomy, human dignity, and social justice.
First, altruism refers to the concern for the welfare and well-being of others without personal...

The Professional Nurse01:22

The Professional Nurse

6.5K
Professional nurses are not limited to bedside care and are taking roles of greater responsibility. A nurse should have a knowledge-based practice, including personal, theoretical, procedural, cultural, and reflexive knowledge. Additionally, nurses must be competent in cognitive, technical, interpersonal, and ethical/legal skills. Some of the best attributes of successful nurses include the following:
Communication skills: These are critical characteristics, especially speaking and listening.

Muscles for Facial Expressions01:14

Muscles for Facial Expressions

4.8K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

56.0K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

659
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Multiple Comparison Tests01:13

Multiple Comparison Tests

4.5K
Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

Summary
This summary is machine-generated.

Professional training courses for facial image comparison do not improve accuracy, even when practitioners believe they do. Longer, specialized training may offer benefits, but current methods lack empirical validation for enhancing identification skills.

Area of Science:

  • Forensic Science
  • Cognitive Psychology
  • Human Factors

Background:

  • Facial image comparison is crucial for national security and criminal investigations.
  • Practitioners receive training to enhance face identification abilities, but its effectiveness is unproven.
  • Existing training programs lack empirical validation regarding accuracy improvement.

Purpose of the Study:

  • To review the content of professional facial image comparison training courses worldwide.
  • To evaluate the effectiveness of representative training courses on face identification accuracy.
  • To determine if current training methods improve accuracy in novices and practitioners.

Main Methods:

  • Content analysis of eleven professional training courses.
  • Pre- and post-training accuracy assessment of face identification in 152 novices and 236 practitioners.
  • Evaluation of four representative training courses, including short and 3-day programs.

Main Results:

  • Short training courses (1-hour, half-day) showed no improvement in identification accuracy.
  • Despite perceived improvement by 93% of trainees, objective accuracy did not increase.
  • A 3-day course showed minor, inconsistent improvements, lacking qualitative changes associated with expertise.

Conclusions:

  • Current short-term professional training courses are ineffective in improving facial image identification accuracy.
  • Longer, examination-focused training and longitudinal approaches may be necessary for skill development.
  • Agencies should seek evidence-based strategies to enhance face identification decisions due to the lack of validated training.
