“…Previous work suggests that world-centered aftereffects can be fragile, for phenomena such as duration compression ( Bruno, Ayhan, & Johnston, 2010 ; Burr, Tozzi, & Morrone, 2007 ), motion ( Knapen, Rolfs, & Cavanagh, 2009 ; Turi & Burr, 2012 ), and tilt aftereffects ( Knapen, Rolfs, Wexler, & Cavanagh, 2010 ; Melcher, 2005 ), although reasons for these inconsistent findings in previous work and this work are not clear. Lack of evidence for an aftereffect in the world-centered reference frame in Experiment 5 is in general agreement with previous work showing that attentional and memory factors can affect the remapping of information about objects in the visual field to world-centered coordinates ( Crespi et al, 2011 ; Laurin et al, 2021 ; Mathot & Theeuwes, 2011 ; Prime, Vesia, & Crawford, 2011 ; Yao, Treue, & Krishna, 2016 ; Yoshimoto & Takeuchi, 2019 ). In Experiment 5 , in comparison to the earlier experiments, there were multiple positions on the screen where stimuli were presented across blocks.…”

Exposure to a dynamic texture reduces the perceived separation between objects, altering the mapping between physical relations in the environment and their neural representations. Here we investigated the spatial tuning and spatial frame of reference of this aftereffect to understand the stage(s) of processing where adaptation-induced changes occur. In Experiment 1, we measured apparent separation at different positions relative to the adapted area, revealing a strong but tightly tuned compression effect. We next tested the spatial frame of reference of the effect, either by introducing a gaze shift between adaptation and test phase (Experiment 2) or by decoupling the spatial selectivity of adaptation in retinotopic and world-centered coordinates (Experiment 3). Results across the two experiments indicated that both retinotopic and world-centered adaptation effects can occur independently. Spatial attention to the location of the adaptor alone could not account for the world-centered transfer we observed, and retinotopic adaptation did not transfer to world-centered coordinates after a saccade (Experiment 4). Finally, we found that aftereffects in different reference frames have a similar, narrow spatial tuning profile (Experiment 5). Together, our results suggest that the neural representation of local separation resides early in the visual cortex, but it can also be modulated by activity in higher visual areas.

“…For example, Yoshimoto et al (2014) showed that positive priming was predominantly reported in spatiotopic coordinates, implicating the role of frontal-parietal regions ( Liu, Yu, Peter, & Cavanagh, 2019 ). In a later study Yoshimoto and Takeuchi (2019) found that directing attention away from the ambiguous test stimulus abolished the positive priming effect, strongly suggesting that attention is needed to induce positive priming. Recently, we showed that modulating participant's expectations about the range of possible motion sequences they might perceive influenced their reports of positive priming but failed to affect reports of negative priming ( Heller & Davidenko, 2018 ).…”

“…There is evidence that the different percepts determined by stimulus parameters result from separate underlying mechanisms, one producing negative priming and the other producing positive priming ( Pantle, Gallogly, & Piehler, 2000 ; Kanai & Verstraten, 2005 ; Yoshimoto et al, 2014 ; Heller & Davidenko, 2018 ; Yoshimoto & Takeuchi, 2019 ). Moreover, the evidence suggests that positive priming involves processes that are higher order than those responsible for negative priming.…”

Visual priming of two-step motion sequences

Perception of an ambiguous apparent motion is influenced by the immediately preceding motion. In positive priming, when an observer is primed with a slow-pace (1–3 Hz) sequence of motion frames depicting unidirectional drift (e.g., Right–Right–Right–Right), subsequent sequences of ambiguous frames are often perceived to continue moving in the primed direction (illusory Right–Right …). Furthermore, priming an observer with a slow-pace sequence of rebounding apparent motion frames that alternate between opponently coded motion directions (e.g., Right–Left–Right–Left) leads to an illusory continuation of the two-step rebounding sequence in subsequent random frames. Here, we show that even more arbitrary two-step motion sequences can be primed; in particular, two-step motion sequences that alternate between non-opponently coded directions (e.g., Up–Right–Up–Right; staircase motion ) can be primed to be illusorily perceived in subsequent random frames. We found that staircase sequences, but not drifting or rebounding sequences, were primed more effectively with four priming frames compared with two priming frames, suggesting the importance of repeating the sequence element for priming arbitrary two-step motion sequences. Moreover, we compared the effectiveness of motion primes to that of symbolic primes (arrows) and found that motion primes were significantly more effective at producing prime-consistent responses. Although it has been proposed that excitatory and rivalry-like mechanisms account for drifting and rebounding motion priming, current motion processing models cannot account for our observed priming of staircase motion. We argue that higher order processes involving the recruitment and interaction of both attention and visual working memory are required to account for the type of two-step motion priming reported here.
