Previous research [M. Luyat, E. Gentaz, Body tilt effect on the reproduction of orientations: studies on the visual oblique effect and subjective orientations, J. Exp. Psychol. Hum. Percept. Perform. 28 (2002) 1002-1011. M. Luyat, E. Gentaz, T.R. Corte, M. Guerraz, Reference frames and haptic perception of orientation: body and head tilt effects on the oblique effect, Percept. Psychophys. 63 (2001) 541-554], using head tilt paradigm to uncouple the gravitational, egocentric and subjective reference frames, showed that the oblique effect was mapped in a subjective gravitational reference frame with the subjective vertical as a cardinal orientation. However, the subjective vertical is not only affected by the tilt of head but also by the tilt of visual context. Then, the tilt of visual oriented cues is another paradigm permitting to evidence the role of the subjective gravitational reference frame. Sixteen participants were asked to reproduce five different orientations of a luminous line: horizontal (0 degrees ), 45 degrees (oblique), 90 degrees (vertical), 135 degrees (oblique) and the subjective vertical. These orientations were reproduced with no visual contextual cues and with tilted visual contextual cues tilted 15 degrees either to the left or to the right. The results showed that the oblique effect decreased with tilted visual contexts but was not completely suppressed. These results proved that this oblique effect is defined in a multimodal reference frame which integrates not only vestibular and proprioceptive cues but also peripheral visual information.Lire moins >
