“…Figure 1 shows the stimulus configuration of a trial in Experiment 1. This configuration was similar to that used in our previous studies (Yoshimoto et al, 2014a;Yoshimoto et al, 2014b) in order to allow comparison with the present results. An achromatic vertical sinewave grating (spatial frequency ¼ 0.5 cycles per degree in visual angle [c/8]) was displayed in a rectangular window (10.08 w 3 3.38 h).…”

“…A darkgray dot with a luminance of 57.9 cd/m 2 and a diameter of 0.58 was displayed to help participants maintain fixation during trials. Similar to our previous studies (Yoshimoto et al, 2014a;Yoshimoto et al, 2014b), we measured the priming effect at four frame of reference conditions (Figure 1). In the retinotopic condition, a dark-gray-colored fixation dot (depicted as a red pot in Figure 1) shifted to the upper region of the screen immediately after the termination of the primer, and the test stimulus was presented in the same retinotopic location as the primer relative to fixation after a variable interstimulus interval (ISI; Figure 1A).…”

Yoshimoto et al (2014aYoshimoto et al ( , 2014b showed that positive priming in spatiotopic conditions was observed only when the interval between the priming and test stimuli was longer than 400 ms. Therefore, as in Yoshimoto et al (2014b), the ISI between the offset of the primer and onset of the test stimulus was changed from 400 to 3,000 ms for this experiment.…”

“…A standard way of examining the spatiotopic effect is to present an observer with two stimuli over time in the same spatial (screen-based) position, separated by a saccade that causes the two stimuli to fall in different retinal locations (Melcher, 2005;Melcher & Colby, 2008;Melcher & Morrone, 2015). Preparing two moving stimuli and examining whether these moving stimuli interact through adaptation or priming would help us to understand the characteristics of spatiotopic effects on visual motion perception (Biber & Ilg, 2011;Burr, Cicchini, Arrighi, & Morrone, 2011;Burr, Tozzi, & Morrone, 2007;Ezzati, Golzar, & Afraz, 2008;Fracasso, Caramazza, & Melcher, 2010;Knapen et al, 2009;Melcher & Fracasso, 2012;Melcher & Morrone, 2003;Ong, Hooshvar, Zhang, & Bisley, 2009;Seidel Malkinson, Mckyton, & Zohary, 2012;Turi & Burr, 2012;Wenderoth & Wiese, 2008;Yoshimoto, Uchida-Ota, & Takeuchi, 2014a;Yoshimoto, Uchida-Ota, & Takeuchi, 2014b; see summary by Marino & Mazer, 2016, table 3). In this study, consequently, we used the visual motion priming paradigm (Ong et al, 2009;Yoshimoto et al, 2014a;Yoshimoto et al, 2014b) in addition to concurrently conducting a dot contrast-change detection task (Crespi et al, 2011) to control the spatial attention of spatiotopic motion perception.…”

“…In our previous studies (Yoshimoto et al, 2014a;Yoshimoto et al, 2014b), participants performed saccades after the offset of a drifting sine-wave priming stimulus and judged the direction of a directionally ambiguous test stimulus that was displayed in retinotopic or spatiotopic coordinates. Through these examinations, we found that positive motion priming is spatiotopic whereas negative priming is predominantly retinotopic.…”

#We almost never experience visual instability, despite retinal image instability induced by eye movements. How the stability of visual perception is maintained through spatiotopic representation remains a matter of debate. The discrepancies observed in the findings of existing neuroscience studies regarding spatiotopic representation partly originate from differences in regard to how attention is deployed to stimuli. In this study, we psychophysically examined whether spatial attention is needed to perceive spatiotopic visual motion. For this purpose, we used visual motion priming, which is a phenomenon in which a preceding priming stimulus modulates the perceived moving direction of an ambiguous test stimulus, such as a drifting grating that phase shifts by 1808. To examine the priming effect in different coordinates, participants performed a saccade soon after the offset of a primer. The participants were tasked with judging the direction of a subsequently presented test stimulus. To control the effect of spatial attention, the participants were asked to conduct a concurrent dot contrast-change detection task after the saccade. Positive priming was prominent in spatiotopic conditions, whereas negative priming was dominant in retinotopic conditions. At least a 600-ms interval between the priming and test stimuli was needed to observe positive priming in spatiotopic coordinates. When spatial attention was directed away from the location of the test stimulus, spatiotopic positive motion priming completely disappeared; meanwhile, the spatiotopic positive motion priming at shorter interstimulus intervals was enhanced when spatial attention was directed to the location of the test stimulus. These results provide evidence that an attentional resource is requisite for developing spatiotopic representation more quickly.

A basic principle in visual neuroscience is the retinotopic organization of neural receptive fields. Here, we review behavioral, neurophysiological, and neuroimaging evidence for nonretinotopic processing of visual stimuli. A number of behavioral studies have shown perception depending on object or external-space coordinate systems, in addition to retinal coordinates. Both single-cell neurophysiology and neuroimaging have provided evidence for the modulation of neural firing by gaze position and processing of visual information based on craniotopic or spatiotopic coordinates. Transient remapping of the spatial and temporal properties of neurons contingent on saccadic eye movements has been demonstrated in visual cortex, as well as frontal and parietal areas involved in saliency/priority maps, and is a good candidate to mediate some of the spatial invariance demonstrated by perception. Recent studies suggest that spatiotopic selectivity depends on a low spatial resolution system of maps that operates over a longer time frame than retinotopic processing and is strongly modulated by high-level cognitive factors such as attention. The interaction of an initial and rapid retinotopic processing stage, tied to new fixations, and a longer lasting but less precise nonretinotopic level of visual representation could underlie the perception of both a detailed and a stable visual world across saccadic eye movements.

Motion perception under mesopic vision

Mesopic and scotopic vision extend over an illuminance range of 106. The goal of the present study was to determine the effect of decreasing light level on the underlying motion mechanism that integrates spatiotemporally separated motion signals. To accomplish this, we took advantage of the phenomenon of visual motion priming, in which the perceived direction of a directionally ambiguous test stimulus is influenced by the directional movement of a preceding priming stimulus. After terminating a drifting priming stimulus, a 180° phase-shifted grating was presented as a test stimulus. The priming and test stimuli were separately presented to the central and peripheral retinas, respectively. The participants judged the perceived direction of this test stimulus at various light levels from photopic to scotopic levels. We found that the effects of motion priming disappeared over 1 log unit of mesopic light levels. When the test stimulus was presented before the offset of the priming stimulus to compensate for the temporal delay in the rod pathway or when both stimuli were presented at the same location in the periphery, a motion-priming effect appeared at mesopic light levels. These results suggest that different temporal characteristics between the cone pathway and rod pathway disturb the function of the putative motion mechanism responsible for the spatiotemporal integration of motion signals, which leads to specific modulation of motion perception over a wide range of mesopic vision.
