“…According to the previous explanation, geocentric judgements would be attracted towards the whole Z-body axis, regardless of the perception of tilt (Carriot, DiZio, & Nougier, 2008). This whole-body attraction has been reported more or less important, however, depending on the dimension of body tilt (roll vs. pitch;Ebenholtz, 1970) or the direction to be estimated (vertical vs. horizontal;Betts & Curthoys, 1998;Carriot et al, 2008;Lejeune, Thouvarecq, Anderson, Caston, & Jouen, 2009). Alternatively, the Z-trunk axis and the Z-head axis were also shown to constitute relevant egocentric references influencing the perception of earthbased directions (Guerraz, Poquin, Luyat, & Ohlmann, 1998;Wade, 1969Wade, , 1970Wetzig & Baumgarten, 1990).…”
