La indiferencia a la disonancia en los nativos amazónicos revela una variación cultural en la percepción de la música
Nature
|July 14, 2016
Resumen
Las preferencias de consonancia musical no son universales. El Tsimane amazónico aislado
Área de la Ciencia:
- Psicología
- Musicología
- Antropología
Sus antecedentes:
- La percepción de la consonancia musical y la disonancia es un debate de larga data en musicología y psicología.
- La teoría de la música occidental plantea un contraste entre las combinaciones de sonidos consonantes (agradables) y disonantes (desagradables).
- Los orígenes de las preferencias de consonancia se debaten, con teorías que sugieren raíces biológicas o condicionamiento cultural.
Objetivo del estudio:
- Investigar las variaciones interculturales en las preferencias de consonancia.
- Para determinar si las preferencias de consonancia son innatas o culturalmente adquiridas.
- Examinar las respuestas estéticas a la música en una población con una exposición cultural occidental mínima.
Principales métodos:
- Se realizaron experimentos con el pueblo Tsimane' de la Amazonía, una sociedad con una exposición limitada a la cultura occidental.
- Se incluyeron grupos de comparación de Bolivia y los Estados Unidos, con diversos grados de exposición a la música occidental.
- Los participantes calificaron la agradabilidad de varios acordes musicales consonantes y disonantes y las armonías vocales.
Principales resultados:
- Los participantes del Tsimane calificaron los acordes consonantes y disonantes y las armonías vocales como igualmente agradables.
- A pesar de esto, los Tsimane' demostraron habilidades de discriminación similares a las occidentales y respuestas estéticas a sonidos familiares y rugosidad acústica.
- Los habitantes urbanos bolivianos mostraron una preferencia por la consonancia, aunque menos pronunciada que los residentes de los Estados Unidos.
Conclusiones:
- Las preferencias de consonancia pueden estar ausentes en culturas aisladas de la música occidental, desafiando las teorías de sesgo innato.
- Los resultados sugieren que las preferencias de consonancia no están vinculadas a los sonidos naturales armónicos.
- La exposición cultural a la armonía musical parece ser el factor dominante que da forma a las respuestas estéticas a la música.

Auditory Perception
1.4K
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

Perceiving Loudness, Pitch, and Location
1.3K
The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...

Perception of Sound Waves
5.9K
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...

Factors Affecting Perception
3.0K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

Sound Intensity Level
5.0K
Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and...

Causes of Similarity-Dissimilarity Effect

The similarity-dissimilarity effect, a fundamental concept in social psychology, explains how interpersonal similarities and differences influence attraction and social interactions. This effect is supported by three key psychological perspectives: balance theory, social comparison theory, and consensual validation.Balance Theory and Cognitive ConsistencyBalance theory, developed by Fritz Heider, posits that individuals seek cognitive consistency in their relationships. When two people share...
