Northeastern University, Department of Psychology, 360 Huntington Avenue, Boston, MA 02115, USA Received 1 July 2003; revised 30 December 2003; accepted 7 January 2004 Abstract —We report on the erasure of the iconic memory of an array of 12 black letters flashed on a continuously- present white field. Erasure

and inter-reflections, the screens were masked with a matte black card, which had a circular hole (1.3 deg diameter) at the screen's centre. Both meters have a circular measurement field with a diameter of 1 deg that filled the centre of the unmasked part of the screen. In Fig. 1, the sets of points

of black and white dots that moves coherently with a constant speed. Using these targets, we have been able to explore the role that the contrast between the target and the background play in determining how long it takes for the target to disappear (referred to as the ‘time-to-fade’). 1 For instance

an AB, Wee and Chua (2004) interposed a singleton (an outline square enclosing a distractor) between T1 and T2. Both T1 and T2 were salient, being black among white distractors. A salient letter distractor had no effect on AB. However, interposition of the singleton increased the usual AB effect, and

design for SSDs. By comparison, many contemporary SSDs attempt to provide multiple visual features at once. To explain one device in detail, the EyeMusic takes images from a camera, reduces the spatial resolution to 40 by 24 pixels and simplifies to 6 colours (red, green, blue, yellow, white and black

Philip Kellman examines what might be consid- ered to be an instantaneous texton gradient. Imagine a field of moving black and white dots divided into two regions. There is no difference between the dots in the two regions. However, when a dot moves across the border from one region to the other, it

contains the stimulus to be presented outside the window. The third video board contains a black-and-white image of the window that is used as a key signal for the video switcher. The video switcher selects between the video signals of the first and the second video board on a pixel-by- pixel basis

optical transfer function to describe the system’s performance. By analogy, the fourth paper by Yang and Reeves uses weighted Hermite polynomials (WHPs), i.e. another variation form of Hermite polynomials, to characterize the human visual system as a black box with an emphasis on the spatial inhomogeneity

estimating head motion from video recordings, for example. Stimuli were displayed using 64-bit Unity 5.61f1 (Unity Technologies, San Francisco, CA, USA), using the SteamVR platform. The simulated environment comprised a box-shaped room with black floor, walls, and ceiling. The riloid patterns were displayed
