Explicit processing of melodic structure in congenital amusia can be improved by redescription-associate learning.

Congenital amusia is a neurodevelopmental disorder of musical processing. Previous research demonstrates that although explicit musical processing is impaired in congenital amusia, implicit musical processing can be intact. However, little is known about whether implicit knowledge could improve explicit musical processing in individuals with congenital amusia.

Music training is associated with better clause segmentation during spoken language processing.

Musical expertise is known to affect speech perception at units below clause/sentence. This study investigated whether the musician's advantage extends to a higher and more central level of speech processing (i.e.

The autistic brain can process local but not global emotion regularities in facial and musical sequences.

Whether autism spectrum disorder (ASD) is associated with a global processing deficit remains controversial. Global integration requires extraction of regularity across various timescales, yet little is known about how individuals with ASD process regularity at local (short timescale) versus global (long timescale) levels. To this end, we used event-related potentials to investigate whether individuals with ASD would show different neural responses to local (within trial) versus global (across trials) emotion regularities extracted from sequential facial expressions; and if so, whether this visual abnormality would generalize to the music (auditory) domain.

Music-induced emotions influence intertemporal decision making.

People tend to choose smaller, immediate rewards over larger, delayed rewards. This phenomenon is thought to be associated with emotional engagement. However, few studies have demonstrated the real-time impact of incidental emotions on intertemporal choices.

Is Absolute Pitch Associated With Musical Tension Processing?

Absolute pitch (AP) is a superior ability to identify or produce musical tones without a reference tone. Although a few studies have investigated the relationship between AP and high-level music processing such as tonality and syntactic processing, very little is known about whether AP is related to musical tension processing. To address this issue, 20 AP possessors and 20 matched non-AP possessors listened to major and minor melodies and rated the levels of perceived and felt musical tension using a continuous response digital interface dial.

The human brain processes hierarchical structures of meter and harmony differently: Evidence from musicians and nonmusicians.

The processing of temporal structure has been widely investigated, but evidence on how the brain processes temporal and nontemporal structures simultaneously is sparse. Using event-related potentials (ERPs), we examined how the brain responds to temporal (metric) and nontemporal (harmonic) structures in music simultaneously, and whether these processes are impacted by musical expertise. Fifteen musicians and 15 nonmusicians rated the degree of completeness of musical sequences with or without violations in metric or harmonic structures.

Impaired emotional processing of chords in congenital amusia: Electrophysiological and behavioral evidence.

This study investigated whether individuals with congenital amusia, a neurogenetic disorder of musical pitch perception, were able to process musical emotions in single chords either automatically or consciously. In Experiments 1 and 2, we used a cross-modal affective priming paradigm to elicit automatic emotional processing through ERPs, in which target facial expressions were preceded by either affectively congruent or incongruent chords with a stimulus onset asynchrony (SOA) of 200 msec. Results revealed automatic emotional processing of major/minor triads (Experiment 1) and consonant/dissonant chords (Experiment 2) in controls, who showed longer reaction times and increased N400 for incongruent than congruent trials, while amusics failed to exhibit such a priming effect at both behavioral and electrophysiological levels.

The neural basis for understanding imitation-induced musical meaning: The role of the human mirror system.

Music can convey meanings by imitating phenomena of the extramusical world, and these imitation-induced musical meanings can be understood by listeners. Although the human mirror system (HMS) is implicated in imitation, little is known about the HMS's role in making sense of meaning that derives from musical imitation. To answer this question, we used fMRI to examine listeners' brain activities during the processing of imitation-induced musical meaning with a cross-modal semantic priming paradigm.

Musical training modulates the early but not the late stage of rhythmic syntactic processing.

Syntactic processing is essential for musical understanding. Although the processing of harmonic syntax has been well studied, very little is known about the neural mechanisms underlying rhythmic syntactic processing. The present study investigated the neural processing of rhythmic syntax and whether and to what extent long-term musical training impacts such processing.

Neural differences between the processing of musical meaning conveyed by direction of pitch change and natural music in congenital amusia.

Music is a unique communication system for human beings. Iconic musical meaning is one dimension of musical meaning, which emerges from musical information resembling sounds of objects, qualities of objects, or qualities of abstract concepts. The present study investigated whether congenital amusia, a disorder of musical pitch perception, impacts the processing of iconic musical meaning.

Perception of hierarchical boundaries in music and its modulation by expertise.

Hierarchical structure with units of different timescales is a key feature of music. For the perception of such structures, the detection of each boundary is crucial. Here, using electroencephalography (EEG), we explore the perception of hierarchical boundaries in music, and test whether musical expertise modifies such processing.

Conveying the concept of movement in music: An event-related brain potential study.

This study on event-related brain potential investigated whether music can convey the concept of movement. Using a semantic priming paradigm, natural musical excerpts were presented to non-musicians, followed by semantically congruent or incongruent pictures that depicted objects either in motion or at rest. The priming effects were tested in object decision and implicit recognition tasks to distinguish the effects of automatic conceptual activation from response competition.

Spatial conceptual associations between music and pictures as revealed by N400 effect.

The processing of extramusical meaning can be reflected in N400 effects of the ERP. However, how conceptual representations can be activated in music still needs to be specified. We investigated the activation of iconic meaningful representations in music by using a cross-modal semantic priming paradigm with an implicit task.
