Welcome to the demo for the illusory temporal reversal Illusory temporal reversal: demo page General Instructions: In the next page you will access the actual demo. Before you start, please move your mouse cursor onto the rotating background composed of blue crosses, and click once to make sure that the Flash program is working properly. Your eyes should be at about arm's length (~50cm) from the screen. Task Instructions: Now, when the yellow ring disappears from your perception, press any key on the keyboard once, as soon as possible. Note: You may need to repeat the experiment several times (to get acquainted with Motion Induced Blindness, the keypress procedure and the ensuing flash) before actually experiencing the illusion.

Apple Retina Display – Jonesblog By now it seems that most people on the planet have heard of Apple’s latest iPhone, the iPhone 4 which was released today. One of the many compelling features of the new phone is the Retina Display. When Steve Jobs first invoked this term at the WWDC, my eyebrows were raised. Being a retinal scientist, I was immediately skeptical of just what he meant by “retinal display”. I am including images below of the iPhone 1G, the iPhone 3G, the iPhone 4G and the iPad to show some perspective on pixel sizes. As you can see from this image, the iPhone 1G pixels (each composed of a red, green and blue sub-pixel) measure approximately 150μm x 500μm. As in the 1G iPhone, the iPhone 3G pixels are essentially the same size, though with a different contact location. This image of the iPhone 4G LCD is made at the same magnification as the 1G and 3G iPhones illustrating the substantially smaller pixel size in the iPhone 4G. iPhone1: ~150 x 150μm iPhone 3G: ~150μm x 150μm iPhone 4G: ~78μm x 78μm Dr.
Отмеченые поля A и B одинакового цвета (зрительная иллюзия)психо Комната Эймса — это помещение, сконструированное определенным образом, для того, чтобы вызывать оптическую иллюзию. Cоздана офтальмологом и психологом Адельбертом Эймсом в 1946 году, по оригинальной идее Гельмгольца. Комната воспринимается как обычная прямоугольная, хотя на самом деле таковой не является.Дальняя стена расположена под острым углом к одной стене и, соответственно, под тупым углом к другой. Схема комнаты Эймса. Ложная перспектива усугубляется клетчатым полом, и рисунками на полу и потолке. В результате оптической иллюзии, человек, стоящий в ближнем (к наблюдателю) углу такой комнаты, выглядит великаном, а находящийся в дальнем углу — карликом. При передвижении человека из одного угла в другой, создается ощущение, что он увеличивается в размерах или уменьшается.Видео: Комментариев: 10

Art as Visual Research: 12 Examples of Kinetic Illusions in Op Art This is the fifth article in the Mind Matters series on the neuroscience behind visual illusions. Scientists did not invent the vast majority of visual illusions. Rather, they are the work of visual artists, who have used their insights into the workings of the visual system to create visual illusions in their pieces of art. It was only with the birth of the op art (for “optic art”) movement that visual illusions became a recognized art form. The accompanying slides illustrate several works of art in which objects that are perfectly still appear to move. Slide Shows: Op Art Illusions Are you a scientist?
