To determine the spatial position of an object, observers must integrate position information from the object's components, such as edges, borders, and other structural elements. This process is typically accurate and the perceived position is close to the physical position of the target (He & Kowler,
1991; Kowler & Blaser,
1995). However, there are many factors that contribute to a divergence between the perceived and physical position, including its retinal eccentricity (Müsseler, van der Heijden, Mahmud, Deubel, & Ertsey,
1999), its motion trajectory (Krekelberg,
2001; Krekelberg & Lappe,
2001), changes in frame of reference (Bridgeman, Peery, & Anand,
1997), and adaptation (Whitaker, McGraw, & Levi,
1997). Visual localization has also been shown to be modulated by experimental manipulations of attention, which can yield improved accuracy (Bocianski, Müsseler, & Erlhagen,
2010; Fortenbaugh & Robertson,
2011) and reliability (Prinzmetal, Amiri, Allen, & Edwards,
1998), but also induce illusory shifts in position perception (Kosovicheva, Fortenbaugh, & Robertson,
2010; Suzuki & Cavanagh,
1997; Tsal & Bareket,
1999; Wright, Morris, & Krekelberg,
2011).
