“…The instructions were frequently repeated to keep subjects alert and concentrated on the task throughout the experiment. We assume that auditory signals did not affect visual localization, as no attentional focus on the spatial location of the sound was required (Bertelson and Radeau 1981;Pick et al 1969;Warren 1979).…”

We investigated the influence of gaze elevation on judging the possibility of passing under high obstacles during pitch body tilts, while stationary, in absence of allocentric cues. Specifically, we aimed at studying the influence of egocentric references upon geocentric judgements. Seated subjects, orientated at various body orientations, were asked to perceptually estimate the possibility of passing under a projected horizontal line while keeping their gaze on a fixation target and imagining a horizontal body displacement. The results showed a global overestimation of the possibility of passing under the line, and confirmed the influence of body orientation reported by Bringoux et al. (Exp Brain Res 185(4):673-680, 2008). More strikingly, a linear influence of gaze elevation was found on perceptual estimates. Precisely, downward eye elevation yielded increased overestimations, and conversely upward gaze elevation yielded decreased overestimations. Furthermore, body and gaze orientation effects were independent and combined additively to yield a global egocentric influence with a weight of 45 and 54%, respectively. Overall, our data suggest that multiple egocentric references can jointly affect the estimated possibility of passing under high obstacles. These results are discussed in terms of ''interpenetrability'' between geocentric and egocentric reference frames and clearly demonstrate that gaze elevation is involved, as body orientation, in geocentric spatial localization.

“…In the ventriloquist illusion, the apparent location of a target sound is shifted towards a visually displaced distracter that moves or flashes in synchrony with that sound (Bermant & Welch, 1976;Bertelson & Aschersleben, 1998;Bertelson & Radeau, 1981;Klemm, 1909). Besides this immediate bias in sound localization, one can also observe aftereffects following prolonged exposure to a ventriloquized sound (Bertelson, Frissen, Vroomen, & De Gelder, 2006;Radeau & Bertelson, 1974.…”

“…For example, synchronized sounds and light flashes with a different spatial location tend to be localized closer together (the ventriloquist effect). The common finding is that there is a substantial effect of the light flashes on the location of the sound (e.g., , but under the right conditions, one can also observe that the sound attracts the location of the light (Bertelson & Radeau, 1981). The spatial attraction thus occurs both ways, and is rather independent of where endogenous or exogenous spatial attention is located (Bertelson, Vroomen, de Gelder, Driver, in press; Vroomen, Bertelson, de Gelder, submitted).…”
