Resumen

Las personas que experimentan alucinaciones verbales auditivas (AVH) muestran una percepción alterada de la emoción, particularmente con estímulos vocales negativos. Esta revisión sistemática pone de relieve un vínculo consistente entre la audición de voces y las dificultades para reconocer emociones.

Área de la Ciencia:

La neurociencia
La psiquiatría
Psicología

Sus antecedentes:

Las alucinaciones auditivas verbales (AVH) implican escuchar voces sin estímulos externos.
Investigaciones anteriores sugieren una conexión entre AVH y la percepción alterada de la emoción.

Objetivo del estudio:

Revisar sistemáticamente la relación entre la percepción de las emociones y la AVH.
Determinar si estas alteraciones son consistentes e influenciadas por el estado clínico y las características del estímulo.

Principales métodos:

Búsqueda sistemática de la literatura en las bases de datos Web of Science y Pubmed.
Análisis de 18 artículos que incluyen 21 tareas experimentales.

Principales resultados:

Las personas con AVH demostraron una menor precisión en el reconocimiento de emociones.
Los marcadores neuronales indicaron una alteración en la decodificación de las emociones, especialmente para los estímulos vocales negativos.

Conclusiones:

La percepción alterada de la emoción en AVH está influenciada por la valencia y la complejidad emocionales, particularmente para el habla y los estímulos negativos.
La percepción atípica de emociones vocales negativas se observa con frecuencia en los estudios de AVH.

Palabras clave:

Auditory Perception

Auditory Perception

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

Perceiving Loudness, Pitch, and Location

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...

Auditory Pathway

Auditory Pathway

Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking...

Positive Symptoms Schizophrenia: Hallucinations and Delusions

Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

Hearing

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Labeling Emotion

Labeling Emotion

Emotional labeling is a cognitive process that involves identifying and naming one's emotions, such as anger, fear, happiness, or sadness. It allows individuals to recognize and express their internal emotional states, a critical aspect of emotional regulation and communication. Labeling emotions requires more than mere recognition; it also involves drawing upon memory and contextual cues to understand the current situation and apply a corresponding emotional label. For instance, feeling...
