TL;DR: The model with latent classes and specificities gave a better fit to the data and made the acoustic correlates of the common dimensions more interpretable, suggesting that musical timbres possess specific attributes not accounted for by these shared perceptual dimensions.
Abstract: To study the perceptual structure of musical timbre and the effects of musical training, timbral dissimilarities of synthesized instrument sounds were rated by professional musicians, amateur musicians, and nonmusicians The data were analyzed with an extended version of the multidimensional scaling algorithm CLASCAL (Winsberg & De Soete, 1993), which estimates the number of latent classes of subjects, the coordinates of each timbre on common Euclidean dimensions, a specificity value of unique attributes for each timbre, and a separate weight for each latent class on each of the common dimensions and the set of specificities Five latent classes were found for a three-dimensional spatial model with specificities Common dimensions were quantified psychophysically in terms of log-rise time, spectral centroid, and degree of spectral variation The results further suggest that musical timbres possess specific attributes not accounted for by these shared perceptual dimensions Weight patterns indicate that perceptual salience of dimensions and specificities varied across classes A comparison of class structure with biographical factors associated with degree of musical training and activity was not clearly related to the class structure, though musicians gave more precise and coherent judgments than did nonmusicians or amateurs The model with latent classes and specificities gave a better fit to the data and made the acoustic correlates of the common dimensions more interpretable

TL;DR: The hypothesis that SAS in dyslexic participants might be responsible for their atypical perception of rapid sequential stimulus sequences in both the auditory and the visual modalities is supported.

TL;DR: This amodal disorder was reported in a dyslexic participant with a phonological disorder, well in accordance with the hypothesis that sluggish auditory attention shifting contributes to difficulties in phoneme awareness and literacy acquisition.

TL;DR: The view that the auditory SAS plays a role in developmental Dyslexia via its impact on phonological abilities is supported and a visual temporal disorder in dyslexia might emerge at a later developmental stage, when the visual system normally becomes more expert at rapid temporal processing.

TL;DR: Evidence that the same participants exhibit similar processing style across modalities strongly supports the idea of a cognitive style to process information and common processing principle in perception.

TL;DR: Investigation of congenital amusia, a lifelong disorder of musical processing, impacts sensitivity to musical emotion elicited by timbre and tonal system information finds amusics rated Western melodies as more tense compared to controls, as they relied less on tonality cues than controls in rating tension for Western melodies.
Abstract: Emotional communication in music depends on multiple attributes including psychoacoustic features and tonal system information, the latter of which is unique to music. The present study investigated whether congenital amusia, a lifelong disorder of musical processing, impacts sensitivity to musical emotion elicited by timbre and tonal system information. Twenty-six amusics and 26 matched controls made tension judgments on Western (familiar) and Indian (unfamiliar) melodies played on piano and sitar. Like controls, amusics used timbre cues to judge musical tension in Western and Indian melodies. While controls assigned significantly lower tension ratings to Western melodies compared to Indian melodies, thus showing a tonal familiarity effect on tension ratings, amusics provided comparable tension ratings for Western and Indian melodies on both timbres. Furthermore, amusics rated Western melodies as more tense compared to controls, as they relied less on tonality cues than controls in rating tension for Western melodies. The implications of these findings in terms of emotional responses to music are discussed.

TL;DR: Work confirms that, neurobiologically, dyslexia is characterised by dysfunction of the normal left hemisphere language network and also implicates abnormal white matter development.

TL;DR: The overall set of data highlights that some musical capacities are acquired through exposure to music without the help of explicit training and reach such a degree of sophistication that they enable untrained listeners to respond to music as "musically experienced listeners" do.

TL;DR: The present 3 year longitudinal study shows that prereading attentional orienting--assessed by serial search performance and spatial cueing facilitation--captures future reading acquisition skills in grades 1 and 2 after controlling for age, nonverbal IQ, speech-sound processing, and nonalphabetic cross-modal mapping.
