Goldstein is Reader in Neuropsychology at the Institute of Psychiatry and Honorary Consultant Clinical Psychologist at the Maudsley Hospital. Here she has provided the clinical neuropsychology service to the Neuropsychiatry Unit at the Lishman Unit for over 15 years. For some of that time she also either worked in the epilepsy surgery programme at the Maudsley Hospital, or was attached to a regional neurology service. She is actively involved in pre- and post-qualification training of clinical psychologists. She devised and still runs the PG Diploma in Clinical Neuropsychology at the Institute of Psychiatry and has been involved in the devel- opments in post-qualification training in clinical neuropsychology being planned by the British Psychological Society. She is actively involved in neuropsychological and other clinical research and has published widely, in areas including motor neurone disease, epilepsy and dissociative seizures, synaesthesia, bipolar disorder and dyspraxia, holding a number of research grants including from the Medical Research Council and Motor Neurone Disease Association. After gaining clinical experience with a wide range of psychiatric conditions and receiving a clinical qualification from the Institute of Psychiatry, Dr Jane E. McNeil took up a position at the National Hospital for Neurology and Neurosur- gery in London, where she specialized in the neuropsychological assessment of a wide range of neurological disorders. Subsequently, Dr McNeil became interested in the practical and treatment applications of theoretical Neuropsychology and moved first to Queen Elizabeth’s Military Hospital, during this time publishing studies of confabulation and acquired disorders of calculation, and then to the Homerton University Hospital in London, where she has worked for the last eight years providing a specialist neuropsychological rehabilitation service to patients with single incident neurological disorders. She studied for her PhD on dyscalculia at the University of London under Professors E. K. Warrington and Robin Morris. She also currently works as a clinical lecturer in neuropsychological rehabilitation at the Institute of Psychiatry and teaches on the PG Diploma in Clinical Neuropsy- chology and the Doctorate in Clinical Psychology. Most recently Dr McNeil has been investigating the efficiency of outcome measures after brain injury and continu- ing investigations into dyscalculia.

The assumption is that, if a species perceives the illusion like humans do, they probably share the same perceptual mechanisms. Here, we investigated whether horses are susceptible to the Muller-Lyer illusion, a size illusion in which two same-sized lines appear to be different in length because of the spatial arrangements of arrowheads presented at the two ends of the lines. Horses showed a human-like perception of this illusion, meaning that they may display similar perceptual mechanisms underlying the size estimation of objects. Abstract: The perception of different size illusions is believed to be determined by size-scaling mechanisms that lead individuals to extrapolate inappropriate 3D information from 2D stimuli. The Muller-Lyer illusion represents one of the most investigated size illusions. Studies on non-human primates showed a human-like perception of this illusory pattern.

    Vision Stefano Ferrari Universit`adegli Studi di Milano [email protected] Methods for Image processing academic year 2016–2017 Biological vision and image processing I The human visual perception results from a chain of processing tasks, often cooperating with other perceptual activities. I Image processing is a discipline (mainly) based on mathematical and statistical concepts, with constraints imposed by the image acquisition technology. I The study of the human vision is useful for more than one reason: I the output of some processes is targeted for the vision of a human user; I the operation of the organs devoted to the acquisition and perception of images can inspire the development of similar artificial devices; moreover, the performance of image processing algorithms have to be compared; I some known mulfunctioning of the biological apparatus do not affect the image processing devices.

  • Visual Perception Glossary
    Visual Perception Glossary Amodal perception The part of an object that is not visible because occlu- ded can be amodally perceived. Amodal perception is different and one step removed from modal percepti- on of real or illusory contours. Apparent motion When an object is presented at two different locati- ons after a brief time interval observers perceive mo- tion. The fi rst empirical investigation was carried out by Sigmund Exner . His aim, as well as the subsequent work by Max Wertheimer , was in establishing that motion was a basic sensation. Attention Refers to the selective processing of some aspect of information, while ignoring other information. The sudden onset of a stimulus can capture attention, but people can also exert some control on where they di- rect their attention. Bi-stable stimulus A particular stimulus that can produce two percepts over time, even though it is unchanged as a stimulus. An example is the Necker cube . Brightness Brightness refers to perception of how much light is coming from a given surface or object. A brighter objects refl ects more light than a less bright object. However perception of brightness is not fully deter- mined by luminance (see Illusory contours). 192 Visual Perception Glossary Cerebral lobe The cerebral cortex of the human brain is divided into four main lobes. Frontal (at the front), occipital (at the back), temporal (on the sides) and parietal (at the top). Consciousness Sorry this is too hard, your guess is as good as mine. Cortex The cortex is the outer layer of the brain . In most mammals the cortex is folded and this allows the surface to have a greater area given in the confi ned space available inside the skull.

  • The Blind Spot
    Sight (Vision) The Blind Spot One of the most dramatic experiments to perform is the demonstration of the blind spot. The blind spot is the area on the retina without receptors that respond to light. Therefore an image that falls on this region will NOT be seen. It is in this region that the optic nerve exits the eye on its way to the brain. To find your blind spot, look at the image below or draw it on a piece of paper: To draw the blind spot tester on a piece of paper, make a small dot on the left side separated by about 6-8 inches from a small + on the right side. Close your right eye. Hold the image (or place your head from the computer monitor) about 20 inches away. With your left eye, look at the +. Slowly bring the image (or move your head) closer while looking at the +. At a certain distance, the dot will disappear from sight...this is when the dot falls on the blind spot of your retina. Reverse the process. Close your left eye and look at the dot with your right eye. Move the image slowly closer to you and the + should disappear. Here are some more images that will help you find your blind spot. For this image, close your right eye. With your left eye, look at the red circle. Slowly move your head closer to the image. At a certain distance, the blue line will not look broken!! This is because your brain is "filling in" the missing information.

This is a world of objects, most of which have pretty fixed properties. The clothes you are currently are always the same color. Yes, children grow, but they tend to grow so slowly that we do not directly observe their growth but can only become aware of growth by looking back across time. Yet, the visual system must use the visual stimulus that enters the eye. The light that comes from a given object may or may not be as constant as the object is. Take the example of a person walking away from you. From Chapter 4, in our discussion of visual angle, it became apparent that as an object gets farther from the eye, the visual angle of that object gets smaller (refer back to Interactive Illustration 4.x, Visual Angle).

  • Systematic Structural Analysis of Optical Illusion Art and Application in Graphic Design with Autism Spectrum Disorder
    SYSTEMATIC STRUCTURAL ANALYSIS OF OPTICAL ILLUSION ART AND APPLICATION IN GRAPHIC DESIGN WITH AUTISM SPECTRUM DISORDER RELATORE :PROF. ARCH. PH.D ANNA MAROTTA CORRELATORE : ARCH. PH.D ROSSANA NETTI STUDENT:LI HAORAN SYSTEMATIC STRUCTURAL ANALYSIS OF OPTICAL ILLUSION ARTAND APPLICATION IN GRAPHIC DESIGN WITH AUTISM SPECTRUM DISORDER Abstract To explore the application of optical illusion in different fields, taking M.C. Escher's painting as an example, systematic analysis of optical illusion, Gestalt psychology, and Geometry are performed. Then, from the geometric point of view, to analyze the optical illusion formation model. Taking Fraser Spiral Illusion and Herring Illusion as examples, through the dismantling and combination of Fraser Spiral Illusion and the analysis of the spiral angle, and Herring Illusion tilt angle analysis, the structure of the graph is further explored. This results in a geometric drawing method that optimizes the optical illusion effect and applies this method to graphic design combined with the autism spectrum. Therefore, this project will remind the ordinary people and designers to pay attention to the universal design while also paying attention to extreme people through the combination of graphic design and optical illusion. That is, focus on autism spectrum disorder (ASD), provide more inclusive design and try their best to provide autism spectrum with the deserving autonomy and independence in public space. Meanwhile, making the autism spectrum “integrate” into the general public’s environment so that their abilities match the environment and improve self-care capabilities.
