“…Several studies have shown the perceiving magnitude in one dimension (e.g., numerosity, size, duration) can alter representations in other dimensions (e.g., Casasanto & Boroditsky, 2008;Cohen, Hansel, & Sylvester, 1953;Oliveri et al, 2008;Xuan, Zhang, He, & Chen, 2007). Thus, it is possible that perceiving stimuli at longer distances could prime some generic representation of 'more' and hence prime larger numerical responses.…”

Much evidence suggests that common posterior parietal mechanisms underlie the orientation of attention in physical space and along the mental number line. For example, the small leftward bias (pseudoneglect) found in paper-and-pencil line bisection is also found when participants "bisect" number pairs, estimating (without calculating) the number midway between two others.For bisection of physical lines, pseudoneglect has been found to shift rightward as lines are moved from near space (immediately surrounding the body) to far space. We investigated whether the presentation of stimuli in near or far space also modulated spatial attention for the mental number line. Participants bisected physical lines or number pairs presented at four distances (60, 120, 180, 240 cm). Clear rightward shifts in bias were observed for both tasks. Furthermore, the rate at which this shift occurred in the two tasks, as measures by least-squares regression slopes, was significantly correlated across participants, suggesting that the transition from near to far space induced a common modulation of lateral attention in physical and numerical space. These results demonstrate a tight coupling between number and physical space, and show that even such prototypically abstract concepts as number are modulated by our on-line interactions with the world.

“…Indeed, the currently available data refer to the visual (e.g., Dormal, Seron, & Pesenti, 2006) or auditory (Droit-Volet, Clement, & Favol, 2003;Xuan, Zhang, He, & Chen, 2007) modality, and typically report that when participants perform a numerosity judgment task, temporal intervals are perceived as shorter than their veridical duration. The investigation of this topic using a multisensory approach could lead to a better understanding of the interplay occurring between the mental representation of time, space, numberand, in general, of magnitudes-in both neurologically intact individuals and ultimately in those patients suffering from parietal lesions, a topic which has been, to our knowledge, by now investigated primarily in the visual modality (e.g., Oliveri et al, 2008Oliveri et al, , 2009Vicario, Pecoraro, Turriziani, Koch, & Oliveri, 2008; see also Bueti & Walsh, 2009). …”

Audiotactile interactions in temporal perception

2011

In the present review, we focus on how commonalities in the ontogenetic development of the auditory and tactile sensory systems may inform the interplay between these signals in the temporal domain. In particular, we describe the results of behavioral studies that have investigated temporal resolution (in temporal order, synchrony/asynchrony, and simultaneity judgment tasks), as well as temporal numerosity perception, and similarities in the perception of frequency across touch and hearing. The evidence reviewed here highlights features of audiotactile temporal perception that are distinctive from those seen for other pairings of sensory modalities. For instance, audiotactile interactions are characterized in certain tasks (e.g., temporal numerosity judgments) by a more balanced reciprocal influence than are other modality pairings. Moreover, relative spatial position plays a different role in the temporal order and temporal recalibration processes for audiotactile stimulus pairings than for other modality pairings. The effect exerted by both the spatial arrangement of stimuli and attention on temporal order judgments is described. Moreover, a number of audiotactile interactions occurring during sensory-motor synchronization are highlighted. We also look at the audiotactile perception of rhythm and how it may be affected by musical training. The differences emerging from this body of research highlight the need for more extensive investigation into audiotactile temporal interactions. We conclude with a brief overview of some of the key issues deserving of further research in this area.Keywords Auditory . Tactile . Temporal . Frequency . Audiotactile . Crossmodal similarities .

MultisensoryThe boundaries between hearing and touch: the foundation of an analogyWe continuously interact with environments that provide a large amount of multisensory information to our various senses. Researchers have now convincingly demonstrated that the inputs delivered by the different sensory channels tend to be bound together by the brain (see the section Research on hearing and touch: a multisensory perspective for a fuller discussion of this topic). Unlike the audiovisual and visuotactile sensory pairings, those interactions taking place at both the neuronal and behavioral level between audition and touch have, to date, been explored in far less detail (see Kitagawa & Spence, 2006;Soto-Faraco & Deco, 2009, for reviews of the extant literature). The paucity of research covering this modality pairing is rather surprising when one considers the wide range of everyday situations in which we experience-even though often in subtle and unconscious ways-the interplay between these two senses. Examples include perceiving the "auditory" buzzing and the itchy "tactile" sensation of an insect landing on the back of our neck; reaching for a mobile phone ringing and vibrating in our pocket. What is common to these situations is the exclusive-or, at the very least, predominant-reliance on cues provided by the

“…It has been observed that a visual stimulus composed of an array of dots is more likely to be judged as "long" when it contains more, larger, or brighter dots (Xuan, Zhang, He, & Chen, 2007). Similarly, the duration of a digit is perceived as being longer for high than for low digits (Oliveri et al, 2008). Finally, empty intervals have also been shown to last subjectively longer when they are bounded by large rather than small markers (Ono & Kitazawa, 2009).…”
