Conditions under which stereopsis and motion perception are blind.
We describe modified random-dot stereograms in which the corresponding elements differ from non-corresponding elements in colour, size, and luminance. Despite these visible differences between the elements, depth perception collapses when the spatially integrated luminous flux is similar for the corresponding and non-corresponding elements. Our results suggest that a low-pass spatial filter pre...
متن کاملPerception of coherent motion, biological motion and form-from-motion under dim-light conditions
Three experiments investigated several aspects of motion perception at high and low luminance levels. Detection of weak coherent motion in random dot cinematograms was unaffected by light level over a range of dot speeds. The ability to judge form from motion was, however, impaired at low light levels, as was the ability to discriminate normal from phase-scrambled biological motion sequences. T...
متن کاملComparing the Role of Lateral Force During Active and Passive Touch: Lateral Force and its Correlates are Inherently Ambiguous Cues for Shape Perception under Passive Touch Conditions
Lateral forces are important cues for shape perception through active touch [1,2]. They can elicit illusory haptic shapes, or perceptually transform the shape of physical objects [1]. Here, it is shown that lateral force, and correlates such as acceleration and velocity, are inherently ambiguous as shape cues under passive touch conditions. The lateral forces arising when passively touching obj...
متن کاملPerson perception by active versus passive perceivers
Person perception research is dominated by studies of passive perceivers who exert no control over the information they receive. In contrast, perceivers in everyday life can often actively choose the type and quantity of information they receive. In this study, active and yoked passive perceivers formed impressions of individuals based on information from Facebook. Compared to active perceivers...
متن کاملActive versus passive processing of biological motion.
Johansson's point-light walker figures remain one of the most powerful and convincing examples of the role that motion can play in the perception of form (Johansson, 1973 Perception & Psychophysics 14 201 - 211; 1975 Scientific American 232(6) 76 - 88). In the current work, we use a dual-task paradigm to explore the role of attention in the processing of such stimuli. In two experiments we find...
