Examining task-dependencies of different attentional processes as reflected in the P3a and reorienting negativity components of the human event-relat…
2005
Abstract Unexpected changes in task-irrelevant auditory stimuli are capable to distract processing of task-relevant visual information. This effect is accompanied by the elicitation of event-related potential (ERP) components associated with attentional orientation, i.e. P3a and reorienting negativity (RON). In the present study we varied the demands of a visual task in order to test whether the RON component – as an index of attentional reorientation after distraction – is confined to a semantic task requiring working memory. In two ERP experiments we applied an auditory-visual distraction paradigm in which subjects were instructed to discriminate visual stimuli preceded by a task-irreleva…
From spatial acoustic changes to attentive behavioral responses within 200 ms in humans
1999
Human event-related potentials (ERPs) and electro-oculograms (EOGs) were recorded in 14 subjects presented with spatially deviant tones in a series of standard tones. In separate sessions, they were instructed to read a book, to count the deviant tones, and to respond to the deviant tones by shifting the eyes towards them from the standard tone source. When reading a book, the mismatch negativity (MMN) of ERP, reflecting pre-attentive detection of acoustic changes, was elicited to the deviant tones at approximately 105-180 ms. No deviance related EOGs were observed in the reading or counting conditions. When the subjects responded behaviorally to the deviant tones, EOGs revealed that the ey…
Perceptual Performance as a Function of Intra-Cycle Cardiac Activity
1975
The purpose of the experiment was to test the hypothesis of a systematic change in perceptual performance within a single cardiac cycle due to the activity of the baroreceptors in carotid sinus. As an index of perceptual performance the ds-parameter from signal detection theory (TSD) was used. A 1000 Hz sine tone had to be detected in a background of white noise. Each of 4 subjects received on the average 4605 noise or noise plus tone stimuli distributed over 10 experimental sessions. When comparing performance during time intervals before and after baroreceptor activity onset no significant difference was found. Also, when tracing perceptual performance over the whole cardiac cycle in step…
Decoding Musical Training from Dynamic Processing of Musical Features in the Brain
2018
AbstractPattern recognition on neural activations from naturalistic music listening has been successful at predicting neural responses of listeners from musical features, and vice versa. Inter-subject differences in the decoding accuracies have arisen partly from musical training that has widely recognized structural and functional effects on the brain. We propose and evaluate a decoding approach aimed at predicting the musicianship class of an individual listener from dynamic neural processing of musical features. Whole brain functional magnetic resonance imaging (fMRI) data was acquired from musicians and nonmusicians during listening of three musical pieces from different genres. Six mus…
Perceiving musical tension in long chord sequences
1999
We attempted to predict perceived musical tension in longer chord sequences by hierarchic and sequential models based on Lerdahl and Jackendoff's and Lerdahl's cognitive theories and on Parncutt's sensory-psychoacoustical theory. Musicians and nonmusicians were asked to rate the perceived tension of chords which were drawn either from a piece composed for the study (Exp. 1) or from a Chopin Prelude (Exps. 2-4). In Exps. 3 and 4, several experimental manipulations were made to emphasize either the global or the local structure of the piece and to verify how these manipultions would affect the respective contribution of the models in the ratings. In all experiments, musical tension was only w…
FOREWORD a Musicologie sans frontières/Muzikologija bez granice/Musicology without frontiers. Essays in Honour of Stanislav Tuksar
2010
La vita e l'opera di Stanislav Tuksar e il suo contributo alla musicologia internazionale. In particolare gli studi di estetica della musica e di storiografia, nonché il suo lavoro di editor della "International Review of the Aesthetics and Sociology of Music" e i saggi importanti sul rapporto tra le culture nazionali e il cosmopolitismo nell'Europa centrale, in relazione alla Croazia e agli Slavi del Sud dal sedicesimo al diciannovesimo secolo.
Does Formal Musical Structure Affect Perception of Musical Expressiveness?
1996
The aim of the study was to assess the effect of systematic modifications in global musical structures on perceived expressiveness. Recorded performances of piano pieces of Bach, Mozart and Schonberg were segmented into short chunks of six seconds in average. These chunks were linked either in a forward order (Original version) or in a backward order (Inverted version). In the inverted version, the formal global structure of the pieces was destroyed, but the superficial features and the local structures inside the chunks were unaltered. Forty non-musician subjects were required to rate the musical expressiveness of these pieces on 29 semantic scales. Half listened to the three original ver…
Sonic Strokes and Musical Gestures - The Difference between Musical Affect and Musical Emotion
2009
Musicological theories traditionally address the expressive powers of music within a framework of signification, in which musical affect is considered as a meaningful musical gesture. Consequently, affect is regarded as a property of the music instead of as a bodily reaction of the listener. I will outline a different conception of musical affect that takes into account the bodily nature of perception. I will introduce the notion of sonic stroke, i.e. a sound that induces affect in the listener. A sonic stroke thus is responsible for the occurrence of musical affect. By relating the notion of sonic stroke to musical gesture the differences between the two can be articulated, as well as how …
Ugo Gaïsser e Francesco Falsone: due pionieri della ricerca sulla musica bizantina degli Albanesi di Sicilia
2016
A Ugo Gaisser, monaco benedettino di origine tedesca, Rettore del Pontificio Collegio Greco di Roma dal 1905 al 1912, va attribuito il merito di aver avviato una specifica attenzione nei confronti della musica bizantina degli Albanesi di Sicilia. Gaisser conobbe personalmente Alberto Favara a Roma durante il Congresso internazionale di Scienze Storiche nel 1903. In quell’occasione Alberto Favara lesse la celebre comunicazione Le melodie tradizionali di Val di Mazzara, mentre Gaisser presentò un contributo dal titolo I canti ecclesiastici italo-greci. Proprio a un allievo di Gaisser, Francesco Falsone, si deve la prima ampia raccolta di trascrizioni musicali (si tratta di circa ben 240 pagin…
I suoni di Amelia
2008
Amelia Rosselli (1930-1996) è stata una delle voci più originali della poesia italiana del secondo dopoguerra. La sua prima vocazione fu quella musicale, cui dovette rinunciare per un combinato di eventi; ma la musica è rimasta un continuo riferimento in tutta la sua produzione poetica. Il saggio inizialmente ricostruisce la formazione e la produzione critica in campo musicale di Amelia Rosselli, per poi identificare nella sua poesia la cifra squisitamente musicale.
