Abstract
La literatura en psicología cognitiva ha enfatizado que la posi-
ción del cuerpo en el espacio y los patrones de búsqueda visual de estímu-
los son variables cruciales para explicar la capacidad de estimar distancias
numéricamente. En este artículo, hemos probado la hipótesis de que la re-
calibración de la propiocepción interfiere en la capacidad de estimar numé-
ricamente el espacio peri-personal fijo. El paradigma experimental Rubber
Hand Illusion (RHI) se aplicó como herramienta para manipular temporal-
mente el sentido de propiocepción en la mano derecha del participante. Se
pidió a diecisiete estudiantes universitarios que, dentro de la RHI, estima-
sen señales espaciales fijadas horizontalmente antes y después de dos con-
diciones de estimulación táctil (estimulaciones síncronas x asíncronas). Los
resultados evidenciaron que la recalibración proprioceptiva de la mano fue
temporalmente alterada por ambos patrones de estimulación. Sin embargo,
los efectos de estimar las señales fijas numéricamente en dirección de la lí-
nea media del cuerpo sólo fueron observados consistentemente en la con-
dición de estimulación síncrona.
Estos resultados sugieren que la estimación numérica de señales fijas peri-
personales está fuertemente asociadas con la recalibración proprioceptiva,
corroborando la literatura sobre integración multisensorial de la percep-
ción.
Research in cognitive psychology has emphasized that the body's position in space and patterns of visual searching for stimuli are crucial variables to explain the ability to estimate distances numerically. In this paper, we tested the hypothesis that proprioception recalibration inter- feres in the ability to numerically estimate fixed peri-personal space. The Rubber Hand Illusion (RHI) experimental paradigm was applied as a tool to temporally manipulate the sense of proprioception in participant’s right hand. Seventeen college students were asked to estimate horizontal fixed spatial cues before and after two conditions of tactile stimulation within RHI (synchronous versus asynchronous stroking). Results evidenced that proprioceptive recalibration of the hand were temporally altered by both stroking patterns. However, the effects of numerically estimate fixed hori- zontal cues towards the body midline were only consistently observed in the synchronous stroking condition. These findings suggest that numerical estimates of peri-personal fixed cues are strongly associated with proprio- ceptive recalibration, corroborating the literature on multisensory integra- tion of perception.
