Attention alters appearance
information than it can process effectively. The high energy cost of neuronal activity involved in cortical computation severely limits our capacity to process this information1. Visual attention serves as a mediating mechanism, enabling us to selectively grant priority of processing to certain aspects of the visual scene. One means of granting priority is to direct one’s gaze towards the relev...
متن کاملAttention alters the appearance of spatial frequency and gap size.
Transient attention is the automatic and short-lasting preferential processing of an area in visual space initiated by sudden stimulation in the same vicinity. Transient attention enhances early visual processing in a variety of dimensions, increasing contrast sensitivity, spatial resolution, and acuity. A recent study established that the increase in contrast sensitivity is accompanied by an i...
متن کاملAttention alters the appearance of motion coherence.
Selective attention enhances visual information processing, as measured by behavioral performance and neural activity. However, little is known about its effects on subjective experience. Here, we investigated the effect of transient (exogenous) attention on the appearance of visual motion, using a psychophysical procedure that directly measures appearance and controls for response bias. Observ...
متن کاملCross-modal cueing of attention alters appearance and early cortical processing of visual stimuli.
The question of whether attention makes sensory impressions appear more intense has been a matter of debate for over a century. Recent psychophysical studies have reported that attention increases apparent contrast of visual stimuli, but the issue continues to be debated. We obtained converging neurophysiological evidence from human observers as they judged the relative contrast of visual stimu...
متن کاملDissecting Spatial Visual Attention
it has been recognized that at least two forms of spatial attention can be found in vision. For example, Wundt (1902) observed that attention could be involuntary or voluntary. A variety of distinctions have been made that more or less correspond to Wundt’s distinction, including goal-directed attention versus stimulus-driven capture and endogenous attention versus exogenous attention. the term...
