“…This does not mean that tasks involving linguistic labels might not show a general spatial representation of pitch (e.g. see Bottini et al (2015) for the role of language on the spatial representations of time in the blind). The present results strongly suggest the need to investigate whether other spatial mappings of magnitudes, documented with vision, also hold for touch.…”

The aim of the present study is to investigate whether the crossmodal correspondence robustly documented between auditory pitch and visual elevation has analogues in the audio-tactile domain. Across 4 experiments, the compatibility effects between intuitively congruent pairs of stimuli (i.e., outward tactile movement, going from the inside of the finger toward the fingertip and increasing pitch, or inward tactile movement and decreasing pitch) and incongruent pairs stimuli (i.e., the reverse associations) were measured. Two methods were compared to assess the behavioral effects of such a correspondence: One where participants have to respond to either the auditory or tactile stimulus presented simultaneously, while ignoring the other (speeded classification task), and the other where the auditory and tactile stimuli are presented sequentially and associated to different response buttons (implicit association test). No significant compatibility effect was observed under the speeded classification task. The implicit association test revealed a significant compatibility effect. This effect was similar in the conditions where the finger was placed vertically and horizontally. However, this implicit association between pitch and tactile movements was not observed in blind participants. These results have methodological implications for the explanation and testing of crossmodal correspondences, and the origin of the widely discussed association between pitch and vertical elevation.

“…Thus, additional walking before a second estimation may not have made enough of a difference to influence judgements of pedestrians. Notably, space and time perception are not independent (e.g., Bottini, Crepaldi, Casasanto, Crollen, & Collignon, 2015). In particular, covered distance has a large impact on time perception (Casasanto & Borodintsky, 2008), suggesting that drivers (covering longer distances) experienced the same time as longer than pedestrians did.…”

What a car does to your perception: Distance evaluations differ from within and outside of a car

Almost a century ago it was first suggested that cars can be interpreted as tools, but consequences of this assumption were never tested. Research on hand-held tools that are used to manipulate objects in the environment suggests that perception of near space is extended by using tools. Literature on environment perception finds perception of far space to be modulated by the observer's potential to act in the environment. Here we argue that a car increases the action potential and modulates perception of far space in a way similar to how hand-held tools modulate perception of near space. Five distances (4 to 20 meters) were estimated by pedestrians and drivers before and after driving/walking. Drivers underestimated all distances to a larger percentage than did pedestrians. Underestimation was even stronger after driving. We conclude that cars modulate the perception of far distances because they modulate the driver's perception, like a tool typically does, and change the perceived action potential.

“…Cette nuance par rapport à l'étude de Castronovo et Seron [32] est importante dans la mesure où elle soutient l'idée selon laquelle différentes informations spatiales pourraient être engagées dans des tâches numériques spécifiques [37,38] : une information visuospatiale dans la tâche de comparaison de nombres versus une information verbale-spatiale dans la tâche de jugement de parité. En accord avec ce cadre théorique, la privation visuelle précoce aurait un impact sur la nature du cadre de référence visuo-spatial impliqué dans la tâche de comparaison de nombre mais n'aurait, au contraire, aucun impact sur la nature du cadre de référence verbalspatial impliqué dans la tâche de jugement de parité (voir aussi [39] pour des résultats similaires avec une tâche de congruité espace-temps). Salilas, Grana, El-Yagoubi et Semenza [40] ont par ailleurs démontré que l'orientation spatiale de l'attention avait SYNTHÈSE…”

> Deux fonctions visuo-motrices jouent un rôle important dans le développement des compétences numériques : (1) La vision joue un rôle fondamental dans le traitement des informations environnementales chez la personne voyante en permettant une analyse extrêmement pré-cise de l'espace et des objets qui l'entourent. Depuis fort longtemps, les conséquences de la perte de la vision et les interrogations quant aux mécanismes pouvant pallier l'absence de celle-ci alimentent les débats et passionnent les chercheurs. Qu'arrive-t-il lorsque la vision n'est plus disponible et que nous devons modifier notre utilisation des autres modalités sensorielles afin d'en compenser la perte ? Quelles sont les incidences cognitives réelles de la cécité ? Telle est la question à laquelle nous allons essayer de répondre dans cette revue. Nous étudierons plus particulièrement la façon dont la privation visuelle influence la représentation que nous avons des nombres. Centré sur le développe-ment et la compréhension du système numérique, cet article n'aborde pas tous les aspects de la cognition. Cependant, nous pensons qu'il peut être utile aux cliniciens et aux chercheurs en sciences cognitives. Étudier Vignette (Photo © Inserm -Christophe Baudouin).
