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 years or above participated in the study. Participants ...

Theories of visual perception traditionally have considered a static retinal image to be the starting point for processing; and has considered processing both to be passive and a literal translation of that frozen, two dimensional, pictorial image. This paper considers five problem areas in the analysis of human visually guided locomotion, in which the traditional approach is contrasted to newer ones that utilize dynamic definitions of stimulation, and an active perceiver: (1) differentiation between object motion and self motion, and among the various kinds of self motion (e.g., eyes only, head only, whole body, and their combinations); (2) the sources and contents of visual information that guide movement; (3) the acquisition and performance of perceptual motor skills; (4) the nature of spatial representations, percepts, and the perceived layout of space; and (5) and why the retinal image is a poor starting point for perceptual processing. These newer approaches argue that stimuli must be ...
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 as scene size, emerge in the human brain in time. First, we identified an electrophysiological marker of ...

The aim of this study was to determine the interrelationship of visual-motor integration, visual perception and motor coordination with object control skills in Grade 1-learners in th e North-West Province of South Africa. This study is based on only the baseline data of a longitudinal study (NW-CHILD study) in progress. The Grade 1-learners (N=806) had a mean age of 6.84±0.39 years. The Developmental Test of Visual-Motor Integration (4th ed.) (VMI), was used to evaluate visual skills, while the Test of Gross Motor Development-2 evaluated six object control skills. There was a statistical significant (p?0.01) association between VMI, two object control skills and total score for object control skills. Visual perception had the highest correlation with all the object control skills where a statistically significant (p?0.05) association with five object control skills and the total score was obtained. Motor coordination had small but significant correlations with two object control skills. ...

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 and accuracy of perceptual

The thesis aspires to challenge CP by means of this formal analysis. Whether it belongs to a simple technique or a sophisticated visual scheme of ancient Chinese artists; the representational space of geometry; the making of visual perception by means of technical implements; and the bodily experience in actual space, are all shown to be indispensible parts of the present research. A concluding case study of the Chinese landscape garden gives a further demonstration that the pictorial ideas and visual techniques that once contributed to the iconological and psychological understanding of Chinese painting have also delivered an idealised form of spatial perception within the garden - where the sense of depth is firstly eliminated, and then artistically reconstituted. In this way, the nature of cavalier perspective will therefore have been explored on two levels - in the form of both spatial representation and bodily perception in actual space.. ...

Neurons in the primate medial temporal lobe (MTL) respond selectively to visual categories such as faces, contributing to how the brain represents stimulus meaning. However, it remains unknown whether MTL neurons continue to encode stimulus meaning when it changes flexibly as a function of variable task demands imposed by goal-directed behavior. While classically associated with long-term memory, recent lesion and neuroimaging studies show that the MTL also contributes critically to the online guidance of goal-directed behaviors such as visual search. Do such tasks modulate responses of neurons in the MTL, and if so, do their responses mirror bottom-up input from visual cortices or do they reflect more abstract goal-directed properties? To answer these questions, we performed concurrent recordings of eye movements and single neurons in the MTL and medial frontal cortex (MFC) in human neurosurgical patients performing a memory-guided visual search task. We identified a distinct population of ...

Our interests include the properties of visual attention and of spatial maps, visual perception during eye and head movements, the information and use of multiple cues for the perception of depth and motion, the perception of duration of visual events, and visual decision processes. We also do research on hearing and touch, especially in their interactions with and analogies to vision. Our methodological approaches are mostly experimental (visual psychophysics) with links to modeling and brain imaging ...
An emerging topic in behavioural biology and psychology is brain lateralization. E.g. the asymmetrical organization of the brain in the left right plain. At first, this phenomenon was described only in humans, and was regarded as one of the extraordinary features of our „superior‟ brain. Later, it was discovered that lateralization exists in many animal species. This asymmetrical organization of the brain results in asymmetrical output called behaviour. The most common example of this in humans is handedness. Asymmetry is described in more and more behaviours, but its origin remains debated. Are they simply „nature‟; hard-coded in our DNA? Or are they „nurture‟ and caused by environmental conditions or experience? The subject of this thesis is asymmetries in visual perception in humans. It is easy to think we perceive the world in an unbiased way. But with an asymmetric brain, it is more likely that we also have asymmetrical perception. This study tries to answer some important ...

Visual scene analysis is a computer-based effort to simulate visual perception. It requires the computer to identify which parts of a scene belong together to form objects. The key process is called constraint satisfaction. The computer locates edges and corners where lines come together (called vertexes). The assignment of meaning to each line and vertex has the effect of limiting or constraining the interpretation put on other parts of the scene. The constraints propagate. Each part of the scene, when interpreted, helps to limit possible interpretations of other parts of the scene.. Constraint-propagation eventually produces one interpretation of the whole scene that is consistent with all the evidence. Classic work on visual scene analysis in the mid-60s culminated in a successful program by the 1980s. Success, in this case, was defined by a computers ability to start with a visual image from a camera and identify boundaries of all objects in the scene, while specifying which lines, ...

Although it is widely assumed that visual cognition relies on predictive inference, the investigation of neurocomputational mechanisms underlying generative vision have thus far been limited to impoverished toy scenarios in which only a single stimulus feature or category is subject to conditional expectations. Here, we built on this work to tackle the more complex but realistic scenario of the visual brain managing concurrent expectations for multiple object features and to shed light on the transformation from expectations concerning individual stimulus features to a unified, object-level expectation. To develop and test formal hypotheses, we harnessed computational modeling in combination with behavioral and neuroimaging data, which allowed us to adjudicate between rival possibilities concerning how different feature expectations (and attention) interact in driving perceptual decisions and neural representations (Table 1). Behavioral data (Fig. 1) and fMRI data (Figs. 4, 6) from two ...
