“…Although some studies using static stimuli show that a salient stimulus repels the perceived position of a subsequent target (Suzuki & Cavanagh, 1997;DiGiacomo, & Pratt, 2012) others instead report attraction (Zimmermann, Fink, & Cavanagh, 2013;Yamada, Kawabe, & Miura, 2008). Yamada et al (2011) showed that observers mislocalized a target closer to a salient inducer that preceded it. These authors suggested that the attraction was caused by the averaging of the memorized locations of the target and the precue.…”

We investigated the perceived position of visual targets in apparent motion. A disc moved horizontally through three positions from -10° to +10° in the far periphery (20° above fixation), generating a compelling impression of apparent motion. In the first experiment, observers compared the position of the middle of the three discs to a subsequently presented reference. Unexpectedly, observers judged its position to be shifted backward, in the direction opposite that of the motion. We then tested the middle disc in sequences of 3, 5, and 7 discs, each covering the same spatial and temporal extents (similar speeds). The backwards shift was only found for the three-disc sequence. With the extra discs approaching more continuous motion, the perceived shift was in the same direction as the apparent motion. Finally, using a localization task with constant static references, we measured the position shifts of all the disc locations for two-disc, three-disc and four-disc apparent motion sequences. The backward shift was found for the second location of all sequences. We suggest that the backward shift of the second element along an apparent motion path is due to an attraction effect induced by the initial point of the motion.

“…The localization of a target has been investigated by using a relative localization task in which the target location was subjectively compared with the location of a simultaneously presented or a delayed probe. The mislocalization of a target, away from a pre-cued location, occurred when the target and probe were simultaneously presented (Suzuki & Cavanagh, 1997;Yamada et al, 2011). On the other hand, the mislocalization of a target toward a pre-cued location occurred when the target preceded the probe by approximately 1 sec (Yamada et al, 2008b(Yamada et al, , 2011.…”

“…This type of mislocalization occurs because the neural sensitivity of position coding units is inhibited around a focus of attention, and this inhibition resultantly shifts the spatial centroids of population activities of the unit, coding a target location away from the pre-cued location (Suzuki & Cavanagh, 1997). On the other hand, a memorized location of a target is reproduced with a bias toward a pre-cued location (Yamada, Kawabe, & Miura, 2008b, 2012Yamada, Miura, & Kawabe, 2011). The researchers suggest that the spatial distribution of attention modulates location signals of the target around the pre-cued location, and this leads to the mislocalization of the target toward the pre-cued location (Yamada et al, 2008b).…”

“…Previous studies that investigated the mislocalization of a target have employed a cueing paradigm in which external objects were presented to control the location of observers' attentional focus. Because those external objects (such as a bright rectangle) have retinal stimulations at a cued location (e.g., Yamada et al, 2011Yamada et al, , 2012, most of the previous findings are consistent with an idea that the mislocalization of a target towards the external object is caused by memory averaging between a target and an attended external object (Kerzel, 2002). Alternatively, however, it was also possible that the mislocalization of a target occurs because a location signal of a target is directly modulated by spatial distribution of observers' attention.…”

In this way, for a pre-cue based mislocalization of a target, the difference in temporal timing between the target and probe results in the difference in the direction of localization bias.…”

Gaze-cueing of attention distorts visual space

A briefly presented peripheral flash is often mislocalized with a bias toward an attended object. The target mislocalization has been ascribed to the integration of location signals between a target and an attended object, and this results in the mislocalization of the target toward the attended object. It was unclear whether external objects that attract observer's attention were necessary to cause the target mislocalization. This study aimed at examining whether the target mislocalization occurred when the shift of observers' attention was induced by gaze cueing, in which observer's attention is shifted in the direction of other's gaze. This cueing paradigm requires no external object to attract attention, thus it enabled us to directly examine the necessity of external objects in the target mislocalization. Stimuli consisted of a pictorial face, a target, and a probe. First, the pictorial face was presented, and its gaze was shifted so as to look at either upper-right or upper-left. The target was successively presented for 50 msec. After a temporal interval of 0 or 2000 msec was inserted as a retention interval, the probe was presented below the target. The observers' task was to judge whether the target had appeared at the left or right side of the probe location. The target was significantly mislocalized in the direction of gaze shift only when the retention interval was 2000 msec. Moreover, reaction time for detecting a target was shorter at the gazed than non-gazed location. These results suggest that the mislocalization does not require external objects attracting attention. Neural signals of target location are possibly averaged with the attention-induced local change in neural signals, and this results in the target mislocalization toward the gazed location.

Here, we demonstrated that one's own name attracts the subjective location of a visual target. We simultaneously presented observers their own name and others' name in the left and right visual fields. A target circle was presented for 53 ms around the center of the display 200 ms after the names disappeared. Ten observers were required to manually reproduce the target location by pointing with the mouse. The results indicated that the observers significantly mislocalized the target 1.61' on average toward the location of their own name. These observations indicated that the visual space is distorted by one's own name, which biases the spatial distribution of visual attention.
