| الوصف: | espanolAunque la asociacion perceptiva entre la verticalidad y la frecuencia auditiva ha sido ampliamente estudiada, la relacion entre la intensidad y la verticalidad sigue sin entenderse completamente. Mientras que se asume que los sonidos mas y menos intensos estan asociados de forma igual con la elevacion espacial, existen diferencias perceptivas entre los dos tipos de sonidos que sugieren lo contrario. Por ejemplo, los sonidos mas intensos tienden a generar mas actividad, tanto en el aspecto conductual como neuronal, que los sonidos mas flojos. En este estudio, investigamos si esta diferencia influye en la correspondencia transmodal entre la intensidad y la verticalidad. En una fase inicial, los participantes aprendieron asociaciones arbitrarias entre uno de dos tonos que diferian en intensidad (82dB vs. 56 dB) y uno de dos rectangulos coloreados (azul vs. amarillo). Durante la fase experimental, se les presentaron los dos estimulos coloreados (cada uno de ellos localizado por encima o debajo de un punto central de partida), junto con uno de los dos tonos. Los participantes tenian que indicar cual de los dos rectangulos coloreados correspondia al tono previamente asociado moviendo el cursor del raton desde el punto de partida hasta el objetivo. Los resultados mostraron que los participantes fueron significativamente mas rapidos cuando respondian al tono mas intenso cuando el objetivo visual se situaba arriba (condicion congruente) que cuando se situaba abajo (condicion incongruente). Para los sonidos menos intensos no se observaron diferencias entre las condiciones congruente (flojo-abajo) e incongruente (flojo-arriba). En general, este patron de resultados sugiere que las posibles diferencias en la actividad neuronal generadas por sonidos de mayor y menor intensidad influyen el grado en el que la intensidad y la elevacion espacial comparten contenido representacional. EnglishAbstract Although the perceptual association between verticality and pitch has been widely studied, the link between loudness and verticality is not fully understood yet. While loud and quiet sounds are assumed to be equally associated crossmodally with spatial elevation, there are perceptual differences between the two types of sounds that may suggest the contrary. For example, loud sounds tend to generate greater activity, both behaviourally and neurally, than quiet sounds. Here we investigated whether this difference percolates into the crossmodal correspondence between loudness and verticality. In an initial phase, participants learned one-to-one arbitrary associations between two tones differing in loudness (82dB vs. 56dB) and two coloured rectangles (blue vs. yellow). During the experimental phase, they were presented with the two-coloured stimuli (each one located above or below a central “departure” point) together with one of the two tones. Participants had to indicate which of the two-coloured rectangles corresponded to the previously-associated tone by moving a mouse cursor from the departure point towards the target. The results revealed that participants were significantly faster responding to the loud tone when the visual target was located above (congruent condition) than when the target was below the departure point (incongruent condition). For quiet tones, no differences were found between the congruent (quiet-down) and the incongruent (quiet-up) conditions. Overall, this pattern of results suggests that possible differences in the neural activity generated by loud and quiet sounds influence the extent to which loudness and spatial elevation share representational content. |
