Picture Changes During Blinks: Looking Without Seeing and Seeing Without Looking
Observers inspected normal, high quality colour displays of everyday visual scenes while their eye movements were recorded. A large display change occurred each time an eye blink occurred. Display changes could either involve “Central Interest” or “Marginal Interest” locations, as determined from descriptions obtained from independent judges in a prior pilot experiment. Visual salience, as dete...
متن کاملSeeing without being seen
Over the past decade, researchers have reported several impressive discoveries aimed at controlling the flow of light in ways that defy common intuition. Andrea Alù and Nader Engheta, at the University of Texas at Austin and the University of Pennsylvania, in a paper in Physical Review Letters now propose a way of sensing with light through a nearly invisible detector [1]. This follows previous...
متن کاملVisual sensing without seeing.
It has often been assumed that when we use vision to become aware of an object or event in our surroundings, this must be accompanied by a corresponding visual experience (i.e., seeing). The studies reported here show that this assumption is incorrect. When observers view a sequence of displays alternating between an image of a scene and the same image changed in some way, they often feel (or s...
متن کاملSeeing without Seeing? Degraded Conscious Vision in a Blindsight Patient
Blindsight patients, whose primary visual cortex is lesioned, exhibit preserved ability to discriminate visual stimuli presented in their "blind" field, yet report no visual awareness hereof. Blindsight is generally studied in experimental investigations of single patients, as very few patients have been given this "diagnosis". In our single case study of patient GR, we ask whether blindsight i...
متن کاملSeeing Seeing
This paper discusses several key issues concerning consciousness and human vision. A brief overview is presented of recent developments in this area, including issues that have been resolved and issues that remain unsettled. Based on this, three Hilbert questions are proposed. These involve three related sets of issues: the kinds of visual experience that exist, the kinds of visual attention th...
