*  Exercise increases visual cognition in older adults | JOV | ARVO Journals
Impaired vision is a significant independent risk factor for falls among older adults. Impaired vision is also associated with reduced spatial cognition in frequent fallers. Despite the evidence of a strong influence of visual cognitive factors on fall risk in older adults, most guidelines for fall prevention still only focus on visual acuity and corrective eyewear. Regular physical activity alleviates some of the issues related to falls risk (e.g. increased muscle strength, improved neuromuscular control, and reduced reaction time). Increased physical activity may also increase blood flow in the hippocampus, suggesting physical activity can improve spatial cognition. However, it is currently unknown how visual cognition changes with regular exercise participation. The purpose of the current study was to examine changes in visual cognition following a 12-week exercise intervention program. Thirty-four independent living older adults age 60 ...

*  Deep Neural Networks explain spatio-temporal dynamics of visual scene and object processing | JOV | ARVO Journals
Understanding visual cognition means knowing where and when what is happening in the brain when we see. To address these questions in a common framework we combined deep neural networks (DNNs) with fMRI and MEG by representational similarity analysis. We will present results from two studies. The first study investigated the spatio-temporal neural dynamics during visual object recognition. Combining DNNs with fMRI, we showed that DNNs predicted a spatial hierarchy of visual representations in both the ventral, and the dorsal visual stream. Combining DNNs with MEG, we showed that DNNs predicted a temporal hierarchy with which visual representations emerged. This indicates that 1) DNNs predict the hierarchy of visual brain dynamics in space and time, and 2) provide novel evidence for object representations in parietal cortex. The second study investigated how abstract visual properties, such ...

*  Spatial and temporal acuity of visual perception can be enhanced selectively by attentional set. - Wellcome Centre for...
The aim of this research was to study the relationship between perceptual judgments about space and time. If spatial and temporal judgments were dissociable, they should be modulated selectively by attention. We compared the effect of the attentional set upon fine-grained spatial versus temporal discrimination of visual perception in two experiments. Using identical sensory stimulation, we measured perceptual judgments on either the size of a small spatial gap or the duration of a brief temporal gap. The attentional set was manipulated by cuing the task that was most likely to be performed. In one experiment, a neutral cue was also used, to measure relative benefits and costs of spatial and temporal task sets. If the attentional set could be directed selectively to spatial and temporal task-relevant dimensions, performance on both spatial and temporal acuity tasks should be specifically modulated by task cuing. The results showed that the attentional set enhanced the speed ...

*  Object perception: When our brain is impressed but we do not notice it | JOV | ARVO Journals
What do you see in Figure 1: An old or a young woman? Prolonged inspection suggests both-but not simultaneously. When we observe an ambiguous figure, like the "Old/Young Woman" (Boring, 1930), our percept is unstable, changing spontaneously between two or more possible interpretations. The information that enters via our eyes is very often ambiguous, not least due to the projection of the 3D world onto our 2D retinae. Visual perception can thus be viewed as an incessant attempt to solve the visual "inverse problem" of how several perceptual interpretations can result from one and the same retinal image. Given this uncertainty, how is the brain at all able to construct a stable percept of the world, reliable enough for us to act successfully in the world and survive in the long run? There is a general consensus regarding the earliest steps of visual perception, such as the visual areas' retinotopic and ...
*  Temporal dynamics of generalized flash suppression in V4 | JOV | ARVO Journals
A wide range of salient visual stimuli can be made to suddenly disappear from view following the onset of a large surrounding pattern (generalized flash suppression, GFS, Wilke et al (2003)). The interaction of two factors has previously been found to maximize the probability of perceptual suppression in the context of GFS: some kind of interocular interaction other than spatial conflict, combined with the introduction of approximately a second temporal delay between target and surround onset (stimulus onset asynchrony, SOA). In the present study we examined the neurophysiological basis of this observation by means of multielectrode recordings in area V4 of awake monkeys. Specifically, we were interested in whether the increased probability of perceptual target suppression with longer SOAs could be explained by a decay in the firing rate of neuronal populations responding to the target. To test this, we systematically varied the time between target and surround onset between 0 ms ...

*  Illumination assumptions account for individual differences in the perceptual interpretation of a profoundly ambiguous stimulus...
Where might such beliefs come from? It would be hard to ascertain why someone assumes that something is in a shadow or not. In general, one can expect that people assume things to be more likely that they have encountered more often in their past in a Bayesian fashion. For instance, slower speeds are much more commonly encountered than faster speeds, so if someone is exposed to moving stimuli under observation conditions with some uncertainty, they will take into account that slower speeds are more likely than faster ones and downgrade their speed estimates accordingly (Stocker & Simoncelli, 2006). In the color domain, one would expect that someone who has encountered more short-wavelength light to assume a short-wavelength (or bluish) illumination if there is uncertainty about the nature of the illuminant. In contrast, someone who has encountered more long-wavelength lights in their past would be more likely to assume a long-wavelength (or yellowish) illuminant in the same situation. Those are ...
