Larynx01:21

Larynx

3.5K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

437
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...

Physiological Theories: Cannon-Bard Theory of Emotion

1.3K
The Cannon-Bard theory of emotion, proposed by Walter Cannon and Philip Bard, challenges the notion that emotions are solely the result of physiological responses. Instead, this theory suggests that emotional experiences and physiological arousal occur simultaneously but operate through independent mechanisms. This dual response is initiated by the brain, specifically by the thalamus, which plays a critical role in processing sensory information.
Upon perceiving a stimulus, such as a dangerous...

Functionalism01:11

Functionalism

2.0K
William James, John Dewey, and Charles Sanders Peirce were instrumental in founding functional psychology, which draws heavily from Darwin's theory of evolution by natural selection. This theory suggests that individual traits, including behaviors, are adapted to their environments through natural selection. At the heart of functionalism is the concept of adaptation, meaning that a trait enhances an individual's chances of survival and reproduction.
James envisioned psychology's...

Higher Mental Functions of the Brain: Language

2.8K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Hyperpnea and Hyperventilation01:25

Hyperpnea and Hyperventilation

2.0K
Hyperventilation refers to a higher-than-normal rate and depth of breathing, often associated with anxiety attacks. This excessive breathing surpasses the body's need to expel CO2, leading to a condition known as hypocapnia - an unusually low level of carbon dioxide in the blood. Hypocapnia can constrict cerebral blood vessels, reducing blood flow to the brain, which may result in dizziness or fainting. Early signs include tingling and muscle spasms in the hands and face, caused by falling...

Area of Science:

  • Speech and Hearing Sciences
  • Otolaryngology
  • Voice Science

Background:

  • Vocal hyperfunction (VH) is a significant factor in prevalent voice disorders.
  • Current understanding of VH's etiological and pathophysiological mechanisms requires enhancement.
  • Improved knowledge is crucial for advancing prevention, diagnosis, and treatment strategies for VH-related conditions.

Purpose of the Study:

  • To facilitate and guide future research on vocal hyperfunction (VH).
  • To propose a comprehensive theoretical framework for understanding VH.
  • To enhance the scientific basis for managing VH-related voice disorders.

Main Methods:

  • Integration of prevailing clinical perspectives and existing research evidence.
  • Development of a theoretical framework for VH based on a 30-year-old model.
  • Presentation of key hypotheses regarding contributing factors and treatment responses for VH subtypes.

Main Results:

  • A proposed framework categorizes VH into phonotraumatic and nonphonotraumatic types.
  • Multiple interacting factors are identified as contributors to the development and maintenance of VH.
  • Hypotheses are presented on the influence of these factors on VH manifestations and treatment outcomes.

Conclusions:

  • The updated framework aims to direct future research, especially longitudinal studies.
  • Advancing knowledge on VH etiology and pathophysiology is expected.
  • This research should refine the framework and improve evidence-based prevention and clinical management of VH disorders.
