“…While perceptual similarity appeared also to have a role in target perception and masking in Experiment 2, crucially, this was always orthogonal to the impact of identity. Spatial repetition blindness has been demonstrated previously, such that the repetition of a stimulus of the same type impairs perception (Harris et al, 2015;Kanwisher, 1991;Luo & Caramazza, 1996). In the present study, the conditions that created spatial RB exacerbated masking, demonstrating an interaction between RB and OSM.…”

“…Typically, RB has been demonstrated using rapid serial visual presentation (RSVP) streams, in which items are represented at the rate of approximately 10 images per second, and participants are likely to fail to perceive or report the repeated items. RB, however, is not limited to sequential presentation of the items, because it also is found when repeated items are presented simultaneously in different spatial locations, known as Bspatial RB^ (Harris, Wong, & Andrews, 2015;Kanwisher, 1991;Kanwisher & Potter, Fig. 2 Masking magnitude (the difference in accuracy between simultaneous and delayed mask offset conditions) for each of the inducer condition in Experiment 1.…”

The visual system is constantly bombarded with dynamic input. In this context, the creation of enduring object representations presents a particular challenge. We used object-substitution masking (OSM) as a tool to probe these processes. In particular, we examined the effect of target-like stimulus repetitions on OSM. In visual crowding, the presentation of a physically identical stimulus to the target reduces crowding and improves target perception, whereas in spatial repetition blindness, the presentation of a stimulus that belongs to the same category (type) as the target impairs perception. Across two experiments, we found an interaction between spatial repetition blindness and OSM, such that repeating a same-type stimulus as the target increased masking magnitude relative to presentation of a different-type stimulus. These results are discussed in the context of the formation of object files. Moreover, the fact that the inducer only had to belong to the same Btype^as the target in order to exacerbate masking, without necessarily being physically identical to the target, has important implications for our understanding of OSM per se. That is, our results show the target is processed to a categorical level in OSM despite effective masking and, strikingly, demonstrate that this category-level content directly influences whether or not the target is perceived, not just performance on another task (as in priming).

“…For instance, a stroke situated on the left hemisphere might disturb language and comprehension, which reduce the ability to communicate (Karbe et al, 1990 ; Pirmoradi et al, 2016 ). When the right hemisphere is affected, the intuitive thinking, reasoning, solving problems as well as the perception, judgment and the visual-spatial functions could be impaired (Tatemichi et al, 1994 ; Patel et al, 2002 ; Cumming et al, 2012 ; Sun et al, 2014b ; Harris et al, 2015 ; Tiozzo et al, 2015 ; Save-Pédebos et al, 2016 ). It makes thus difficult for patients to locate objects, walk up or down stairs or get dressed.…”

Stroke often aggravated age-related cognitive impairments that strongly affect several aspects of quality of life. However, few studies are, to date, focused on rehabilitation strategies that could improve cognition. Among possible interventions, aerobic training is well known to enhance cardiovascular and motor functions but may also induce beneficial effects on cognitive functions. To assess the effectiveness of aerobic training on cognition, it seems necessary to know whether training promotes the neuroplasticity in brain areas involved in cognitive functions. In the present review, we first explore in both human and animal how aerobic training could improve cognition after stroke by highlighting the neuroplasticity mechanisms. Then, we address the potential effect of combinations between aerobic training with other interventions, including resistance exercises and pharmacological treatments. In addition, we postulate that classic recommendations for aerobic training need to be reconsidered to target both cognition and motor recovery because the current guidelines are only focused on cardiovascular and motor recovery. Finally, methodological limitations of training programs and cognitive function assessment are also developed in this review to clarify their effectiveness in stroke patients.
