Attention induced motion blindness
Recent studies have shown evidence for modulation of cortical activity by attention in visual areas involved in motion processing. Behavioural effects of this modulation have only been reported for high-order, but not for luminance-based motion. We show that attentional load can even affect the perception of a first-order motion inducing a short-termed motion blindness. The detection of transie...
متن کاملMotion-Induced Blindness and Motion Streak Suppression
In motion-induced blindness (MIB), persistent static targets intermittently disappear when presented near moving elements [1, 2]. There is currently no consensus regarding the cause or causes of MIB [3-7]. Here, we link the phenomenon to a mechanism that is integral for normal human vision, motion streak suppression [8]. The human visual system integrates information over time [9], resulting in...
متن کاملA Functional Account of Motion-Induced Blindness
In motion-induced blindness (MIB), salient objects in full view can repeatedly fluctuate into and out of conscious awareness when superimposed onto certain global moving patterns. Here we suggest a new account of this striking phenomenon: Rather than being a failure of visual processing, MIB may be a functional product of the visual system’s attempt to separate distal stimuli from artifacts of ...
متن کاملExtrinsic grouping factors in motion-induced blindness
We investigated how various grouping factors altered subjective disappearances of the individual targets in the motion-induced blindness display. The latter relies on a moving mask to render highly salient static targets temporarily subjectively invisible. Specifically, we employed two extrinsic grouping factors, the connectedness and the common region, and examined whether their presence would...
متن کاملOrientation-selective adaptation during motion-induced blindness.
When a global moving pattern is superimposed on high-contrast stationary or slowly moving stimuli, the latter occasionally disappear for periods of several seconds (motion-induced blindness, MIB). Here, an adaptation paradigm was used to determine if orientation-selective adaptation still occurs for the stimulus that is no longer visible. Two slowly drifting high-contrast Gabor patches were pre...
