Fractionating auditory priors: A neural dissociation between active and passive experience of musical sounds
2019
Learning, attention and action play a crucial role in determining how stimulus predictions are formed, stored, and updated. Years-long experience with the specific repertoires of sounds of one or more musical styles is what characterizes professional musicians. Here we contrasted active experience with sounds, namely long-lasting motor practice, theoretical study and engaged listening to the acoustic features characterizing a musical style of choice in professional musicians with mainly passive experience of sounds in laypersons. We hypothesized that long-term active experience of sounds would influence the neural predictions of the stylistic features in professional musicians in a distinct…
Hippocampus responds to auditory change in rabbits
2010
Any change or novelty in the auditory environment is potentially important for survival. The cortex has been implicated in the detection of auditory change whereas the hippocampus has been associated with the detection of auditory novelty. Local field potentials (LFPs) were recorded from the CA1 area of the hippocampus in waking rabbits. In the oddball condition, a rare tone of one frequency (deviant) randomly replaced a repeated tone of another frequency (standard). In the equal-probability condition, the standard was replaced by a set of tones of nine different frequencies in order to remove the repetitive auditory background of the deviant (now labelled as control-deviant) while preservi…
Perception of musical tension in short chord sequences: The influence of harmonic function, sensory dissonance, horizontal motion, and musical traini…
1996
This study investigates the effect of four variables (tonal hierarchies, sensory chordal consonance, horizontal motion, and musical training) on perceived musical tension. Participants were asked to evaluate the tension created by a chord X in sequences of three chords {C major → X → C major} in a C major context key. The X chords could be major or minor triads major-minor seventh, or minor seventh chords built on the 12 notes of the chromatic scale. The data were compared with Krumhansl’s (1990) harmonic hierarchy and with predictions of Lerdahl’s (1988) cognitive theory, Hutchinson and Knopoff’s (1978) and Parncutt’s (1989) sensory-psychoacoustical theories, and the model of horizontal mo…
Enhanced development of auditory change detection in musically trained school-aged children: a longitudinal event-related potential study
2013
Adult musicians show superior auditory discrimination skills when compared to non-musicians. The enhanced auditory skills of musicians are reflected in the augmented amplitudes of their auditory event-related potential (ERP) responses. In the current study, we investigated longitudinally the development of auditory discrimination skills in musically trained and nontrained individuals. To this end, we recorded the mismatch negativity (MMN) and P3a responses from children who play a musical instrument and age-matched children with no musical training at ages 7, 9, 11, and 13. Basic auditory processing was investigated by recording ERPs in the Multi-Feature Paradigm that included frequency, du…
Effect of different treatments in calcium-free medium on basal tone and contractile responses of guinea pig tracheae.
1995
Acetylcholine (ACh; 0.1 mmol/l) and KCl (80 mmol/l) induce a biphasic contractile response in isolated guinea pig tracheae maintained at 37 degrees C either in the presence or absence of extracellular Ca2+. Exposure of the tissue to Ca(2+)-free solution evokes a significant decrease in basal tone and the sources of Ca2+ appear to be decreased by prolonged agonist stimulation, and even more by successive agonist stimulation. After an incubation period of 20 min in Ca(2+)-containing solution, the response is restored. Mg(2+)-depletion in Ca(2+)-free medium increased the contractile response to ACh, but not to KCl, and delayed the tonic component of the next contraction elicited in Ca(2+)-cont…
A comparison of the effects for sustained versus shifted attention on dichotic listening performance.
2009
We measured the effect of two types of directed attention instructions, sustained by a verbal cue or shifted by a tone cue with different time intervals (150, 450, and 750 ms), on a consonant-vowel dichotic listening (C-V DL) test for a large group of right- and left-handed participants of both sexes. An increasing of the hits and a decreasing of the intrusions from the baseline DL test scores was evident for both types of attentional manipulations, with no differences regarding sex or handedness. Increasing the time from 150 to 450 ms benefited the focusing of attention but this advantage was markedly attenuated at the longer 750-ms interval. The improving effect was seen for the hits of b…
Boosting syntax training with temporally regular musical primes in children with cochlear implants
2018
International audience; Objectives : Previous research has suggested the use of rhythmic structures (implemented in musical material) to improve linguistic structure processing (i.e., syntax processing), in particular for populations showing deficits in syntax and temporal processing (e.g., children with developmental language disorders). The present study proposes a long-term training program to improve syntax processing in children with cochlear implants, a population showing syntax processing deficits in perception and production.Methods : The training program consisted of morphosyntactic training exercises (based on speech processing) that were primed by musical regular primes (8 sessio…
The effects of mothers’ musical background on sedentary behavior, physical activity, and exercise adherence in their 5-6-years-old children using mov…
2017
Objectives The purpose of this study was to examine whether mothers’ musical background has an effect on their own and their children’s sedentary behavior (SB) and physical activity (PA). The aim was also to assess children’s and their mothers’ exercise adherence when using movement-to-music video program. Design Sub-group analysis of an intervention group in a randomized controlled trial (ISRCTN33885819). Method Seventy-one mother-child-pairs were divided into two categories based on mothers’ musical background. Each pair performed 8 weeks exercise intervention using movement-to-music video program. SB and PA were assessed objectively by accelerometer, and exercise activity, fidelity, and …
Multisensory integration of drumming actions: musical expertise affects perceived audiovisual asynchrony
2009
We investigated the effect of musical expertise on sensitivity to asynchrony for drumming point-light displays, which varied in their physical characteristics (Experiment 1) or in their degree of audiovisual congruency (Experiment 2). In Experiment 1, 21 repetitions of three tempos x three accents x nine audiovisual delays were presented to four jazz drummers and four novices. In Experiment 2, ten repetitions of two audiovisual incongruency conditions x nine audiovisual delays were presented to 13 drummers and 13 novices. Participants gave forced-choice judgments of audiovisual synchrony. The results of Experiment 1 show an enhancement in experts' ability to detect asynchrony, especially fo…
MÚSICA Y DESCARGA DE INTERNET: ANÁLISIS DE SUS ANTECEDENTES E IMPLICACIONES DE GESTIÓN
2014
La descarga de música de Internet es un fenómeno cada vez más extendido, que está causando importantes daños a la industria musical. Tomando como referencia la Teoría del Comportamiento Planeado, el presente trabajo trata de identificar las variables que condicionan la intención del individuo de descargarse música no autorizada, incorporando nuevas relaciones no contempladas explícitamente en la teoría considerada. Sólo conociendo el por qué del comportamiento se podrá valorar la posible instrumentalización de acciones a tendentes mejorar la situación por la que atraviesa la industria musical. A partir de los resultados obtenidos, se proponen acciones vinculadas con la gestión.
