Aging alters surround modulation of perceived contrast.
It is well established that many visual functions deteriorate with age. Perhaps counter-intuitively, a recent study revealed that older people actually require less time to discriminate the direction of motion of large, high contrast moving stimuli than young adults (L. R. Betts, C. P. Taylor, A. B. Sekuler, & P. J. Bennett, 2005). L. R. Betts et al. (2005) proposed their finding as evidence fo...
متن کاملExogenous attention enhances 2nd-order contrast sensitivity
Natural scenes contain a rich variety of contours that the visual system extracts to segregate the retinal image into perceptually coherent regions. Covert spatial attention helps extract contours by enhancing contrast sensitivity for 1st-order, luminance-defined patterns at attended locations, while reducing sensitivity at unattended locations, relative to neutral attention allocation. However...
متن کاملCross-modal attention enhances perceived contrast.
Visual Attention Each time we open our eyes, we are confronted with an overwhelming amount of information. How is it possible, then, that we still have a strong impression that we understand what we see? Visual attention is the mechanism that turns looking into seeing, allowing us to select a certain location or aspect of a busy visual scene, and prioritize its processing. Such selection is nec...
متن کاملCue contrast modulates the effects of exogenous attention on appearance
Exogenous spatial attention can be automatically engaged by a cue presented in the visual periphery. To investigate the effects of exogenous attention, previous studies have generally used highly salient cues that reliably trigger attention. However, the cueing threshold of exogenous attention has been unexamined. We investigated whether the attentional effect varies with cue salience. We exami...
متن کاملNonretinotopic Exogenous Attention
Attention is crucial for visual perception because it allows the visual system to effectively use its limited resources by selecting behaviorally and cognitively relevant stimuli from the large amount of information impinging on the eyes. Reflexive, stimulus-driven attention is essential for successful interactions with the environment because it can, for example, speed up responses to life-thr...
