Visuo-Motor Interaction in the Estimation of Distance: Athletes vs. No-Athletes

Abstract

To build a representation of the space surrounding us with an appropriate perceptual precision, our brain has to obtain the distance information from a variety of cues that are present in the scene. But these data are affected in some way by our self-motion perception. Using an indirect method of distance estimation, we investigated the effect of the visuo-motor interactions on the perception of distance in two groups of observers, one of athletes and other of no-athletes. The results showed a difference between the distances obtained in static and dynamic conditions and also in the magnitude of the absolute errors of each group. The data were modeled and interpreted in terms of the Bayesian framework of perceptual inference.

Does who I am and what I feel determine what I see (or say)? A meta-analytic systematic review exploring the influence of real and perceived bodily state on spatial perception of the external environment

“…Two experiments used comparable distance measures, but in athletic populations ( Asaf, Santillán & Barraza, 2015 ; Jarraya et al, 2013 ). Asaf, Santillán & Barraza (2015) showing no difference (Hedge’s g range: −0.13 to 0.09) in distance estimations based on their fatigue manipulation (treadmill running 2 min), whereas Jarraya et al (2013) found very large effect sizes following cycling for 10 mins (Hedge’s g range: 8.32 to 10.08), indicating participants estimated distances as closer in the post-exercise (fatigued) condition compared to the pre-exercise condition. Pooling of the studies’ similar distances (12 m and 11 m) was non-significant, with high heterogeneity (I 2 = 96%).…”

Estimación de la percepción de distancia durante la locomoción

“…Esto se debe a que el cuerpo necesita un tiempo para acostumbrarse al movimiento, especialmente cuando hay una asincronía entre la información interoceptiva y exteroceptiva. Coincidente con trabajos anteriores (Durgin et al, 2005), encontramos que un tiempo de adaptación de dos minutos corriendo a la velocidad empleada en la medición (nosotros utilizamos sobre todo 4 y 8 Km/h) era suficiente para lograr la adaptación, tanto en atletas como en no-atletas (Asaf, Santillán, & Barraza, 2014).…”
