Postural configuration affects the perception of earth-based space during pitch tilt

Abstract: This study investigates the relative contribution of body parts in the elaboration of a whole-body egocentric attraction phenomenon previously observed during earth-based judgments. This was addressed through a particular earth-based task requiring estimating the possibility of passing under a projected line, imagining a forward horizontal displacement. Different postural configurations were tested, involving whole-body tilt, trunk tilt alone or head tilt alone. Two legs positions relative to the trunk were ma… Show more

“…A comparable linear relationship was subsequently observed when judging objects' elevation and the possibility of passing under them, suggesting that the two estimations shared common processes, intimately linked to the perceived horizontal direction (Bringoux, Robic, Gauthier, & Vercher, 2008). The origin of this body tilt effect observed in darkness upon judgements of passability was recently investigated, demonstrating that several body parts could jointly intervene in this phenomenon (Bourrelly, Bringoux, & Vercher, 2009;Bourrelly, Vercher, & Bringoux, 2011). For instance, we previously highlighted the influence of postural configurations, by manipulating whole-body tilt, trunk tilt alone, and head tilt alone (Bourrelly et al, 2011).…”

“…The present study investigated whether orientational visual cues from optic flow may help to reduce the influence of body tilt previously observed in darkness on estimating the passability under a barrier when imagining a forward horizontal displacement (Bourrelly et al, 2009(Bourrelly et al, , 2011Bringoux et al, 2008). The underlying issues were to better understand how spatial references could interact for the perception of space.…”
