Abstract

None:

Auditory verbal hallucinations (AVH) represent the experience of hearing voices in the absence of a corresponding external stimulus. Previous studies have posited a link between AVH and changes in emotion perception. We conducted a systematic review to examine whether such alterations relate consistently to AVH, and to what extent they depend on the participants' clinical status and stimulus characteristics (i.e., sensory modality, complexity, and emotional valence).

Method:

We searched the Web of Science and Pubmed databases for articles examining the relationship between emotion perception and AVH.

Results:

The final sample included 18 articles and a total of 21 experimental tasks. Lower emotion recognition accuracy and alterations in neural indices of emotion decoding from negative vocal stimuli were associated with AVH.

Conclusion:

Altered emotion perception in voice hearers is modulated by emotional valence and complexity: atypical performance was observed more systematically for speech and negative stimulus valence. Despite methodological differences between studies, altered perception of negative vocal emotions in AVH was observed in most studies. We present recommendations for future studies.

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...
