Body movement implied by static images modulates eye movements and subjective time estimation

The present study investigated the influence of body movement implied by artwork on time estimation and its relationship with eye movement. In Experiment 1, the participants were presented with static photographic images of Edgar Degas sculptures that implied different movements. The participants were asked to estimate their exposure times. Overestimation was found for the dancer who represented the greater movement. Eye movements were more directed to legs and arms in the ballerina that implied more movement, indicating more dynamic eye movements for this dancer, which was also overestimated. Experiment 2 further investigated whether this effect was specific to body representation or whether it was linked to the perceptual feature of the images. The participants were presented with drawings that mimicked global shapes (lines) of the Degas sculptures. Differences in time estimation were not obtained under this experimental condition. The results suggest an embodied perception of body movement that modulates eye movements and time estimation...

Escala multidimensional aplicada aos estudos de apreciação musical / Multidimensional scaling applied to studies of musical appreciation

A escala multidimensional (MDS) provém de uma família de técnicas de análise de proximidade de dados, obtida por meio do julgamento do participante que compara vários estímulos em vários traços, concomitantemente. A análise dos julgamentos de proximidade produz um espaço em que pontos representam a relação entre os estímulos em um espaço euclidiano. O ordenamento dos estímulos ao longo das dimensões neste espaço permite que inferências possam ser feitas sobre o universo perceptual subjacente ao grupo de pesquisa. A literatura mostra que a MDS vem ampliando o estudo da música e a mensuração de suas propriedades estruturais.

The multidimensional scaling (MDS) originates from a set of techniques for analyzing proximity of data, which is obtained through the judgments of participants who concomitantly compare several stimuli in various dimensions. The analysis of proximity judgments produces an analysis in which points represent the relationship existent between stimuli in a Euclidean space. The configuration of stimuli in the space defined by these dimensions permits to make inferences about the underlying perceptual universe of the studied group. Literature reveals that MDS is enlarging the study of music and the measurement of its structural properties.

La escala multidimensional (MDS) deriva de una familia de técnicas de análisis de proximidad de datos. Esta proximidad es obtenida a través del juicio de los participantes que comparan diversos estímulos con varias propiedades, al mismo tiempo. El análisis de la evaluación de proximidad produce un espacio en que los puntos representan la relación entre los estímulos en un espacio euclidiano. La clasificación de los estímulos a lo largo de las dimensiones en este espacio, permite realizar inferencias sobre el universo perceptivo del grupo de investigación. La literatura muestra que la MDS amplía el estudio de la música y la medición de sus propiedades estructurales.
