    Auditory stimulus timing influences perceived duration of co-occurring visual stimuli

    There is increasing interest in multisensory influences upon sensory-specific judgments, such as when auditory stimuli affect visual perception. Here we studied whether the duration of an auditory event can objectively affect the perceived duration of a co-occurring visual event. On each trial, participants were presented with a pair of successive flashes and had to judge whether the first or second was longer. Two beeps were presented with the flashes. The order of short and long stimuli could be the same across audition and vision (audio–visual congruent) or reversed, so that the longer flash was accompanied by the shorter beep and vice versa (audio–visual incongruent); or the two beeps could have the same duration as each other. Beeps and flashes could onset synchronously or asynchronously. In a further control experiment, the beep durations were much longer (tripled) than the flashes. Results showed that visual duration discrimination sensitivity (d′) was significantly higher for congruent (and significantly lower for incongruent) audio–visual synchronous combinations, relative to the visual-only presentation. This effect was abolished when auditory and visual stimuli were presented asynchronously, or when sound durations tripled those of flashes. We conclude that the temporal properties of co-occurring auditory stimuli influence the perceived duration of visual stimuli and that this can reflect genuine changes in visual sensitivity rather than mere response bias

    Looming sounds enhance orientation sensitivity for visual stimuli on the same side as such sounds

    Several recent multisensory studies show that sounds can influence visual processing. Some visual judgments can be enhanced for visual stimuli near a sound occurring around the same time. A recent TMS study (Romei et al. 2009) indicates looming sounds might influence visual cortex particularly strongly. But unlike most previous behavioral studies of possible audio-visual exogenous effects, TMS phosphene thresholds rather than judgments of external visual stimuli were measured. Moreover, the visual hemifield assessed relative to the hemifield of the sound was not varied. Here, we compared the impact of looming sounds to receding or "static" sounds, using auditory stimuli adapted from Romei et al. (2009), but now assessing any influence on visual orientation discrimination for Gabor patches (well-known to involve early visual cortex) when appearing in the same hemifield as the sound or on the opposite side. The looming sounds that were effective in Romei et al. (2009) enhanced visual orientation sensitivity (d0) here on the side of the sound, but not for the opposite hemifield. This crossmodal, spatially specific effect was stronger for looming than receding or static sounds. Similarly to Romei et al. (2009), the differential effect for looming sounds was eliminated when using white noise rather than structured sounds. Our new results show that looming structured sounds can specifically benefit visual orientation sensitivity in the hemifield of the sound, even when the sound provides no information about visual orientation itself. © The Author(s) 2011

    Il saggio costituisce una prima riflessione sul nuovo istituto introdotto dal D.Lgs. n. 276/2003, fornendone un inquadramento sistematico sulla base del quale sono poi affrontati i problemi applicativi che scaturiscono dalla disciplina di legge

    Casa Romei, museo dei 5 sensi. Un focus sulla vista

    No full text
    Casa Romei è una antica dimora rinascimentale ferrarese costruita dal mercante Giovanni Romei a partire dal 1443, in seguito ingrandita e abbellita in concomitanza delle sue nozze con Polissena d’Este. I dipinti parietali interni ed esterni, le decorazioni fiorite, la Sala delle Sibille e dei Profeti e i soffitti lignei costituiscono un corpus artistico unico della Ferrara del primo Rinascimento. Con il passaggio di proprietà al Monastero del Corpus Domini (1491) la casa assunse nuove funzioni e aspetto, così come ci ricorda l’elaborato trigramma del cortile d’onore. Le sale del piano superiore, decorate da eleganti grottesche, furono rinnovate dal Cardinale Ippolito II d’Este, figlio di Lucrezia Borgia, sepolta proprio nella chiesa del Corpus Domini [Sardo 2019]. Aperto al pubblico come museo nel 1955, l’edificio è oggi un importante landmark di questo ambito urbano, ed ha aumentato progressivamente il numero dei propri visitatori grazie ad un serrato programma di iniziative tra cui ‘Sogno o Son Deste’, proiezioni luminose notturne sulle facciate della corte d’onore (2018) e il progetto ‘La crocefissione ricomposta’ (2020). Il contributo intende presentare il progetto di ricerca, in corso di realizzazione, intitolato ‘Casa Romei museo dei 5 sensi. Analogico e digitale per una esperienza inclusiva del Rinascimento Ferrarese’, con un focus sulla vista, attraverso i metodi e gli strumenti della rappresentazione.Casa Romei is an ancient Renaissance residence in Ferrara built by the merchant Giovanni Romei starting in 1443, later enlarged and embellished for his wedding to Polissena d’Este. The internal and external wall paintings, the floral decorations, the Rooms of Sibyls and of Prophets and the wooden ceilings constitute a unique artistic corpus of early Ferrara’s Renaissance. With the transfer of ownership to the Corpus Domini Monastery (1491) the house assumed new functions and appearance, as the elaborate trigram of the courtyard of honour reminds us. The rooms on the upper floor, decorated with elegant grotesques, were renovated by Cardinal Ippolito II d’Este, son of Lucrezia Borgia, who was buried in the Corpus Domini church [Sardo 2019]. Opened to the public as a museum in 1955, the building is today an important landmark in this urban area, and has gradually increased the number of its visitors thanks to a tight program of initiatives including ‘Sogno o Son Deste’, light projections on the facades of the corte d’onore at night (2018) and the project ‘The reconstructed crucifixion’ (2020). The paper presents the ongoing research project entitled ‘Casa Romei Museum of the 5 senses. Analog and digital for an inclusive experience of the Ferrara’s Renaissance’, with a focus on the view, through the methods and tools of representation
