Attention alters appearance
- M. Carrasco, S. Ling, Sarah Read
- Psychology, Medicine
- Nature Neuroscience
- 1 March 2004
Does attention alter appearance? This critical issue, debated for over a century, remains unsettled. From psychophysical evidence that covert attention affects early vision—it enhances contrast… Expand
Emotion Facilitates Perception and Potentiates the Perceptual Benefits of Attention
- E. Phelps, S. Ling, M. Carrasco
- Psychology, Medicine
- Psychological science
- 1 April 2006
Does emotion affect how people see? We investigated the effects of emotion and attention, as well as their conjoint effect, on contrast sensitivity, a dimension of early vision. We manipulated the… Expand
How spatial and feature-based attention affect the gain and tuning of population responses
- S. Ling, Taosheng Liu, M. Carrasco
- Psychology, Medicine
- Vision Research
- 2 June 2009
How does attention optimize our visual system for the task at hand? Two mechanisms have been proposed for how attention improves signal processing: gain and tuning. To distinguish between these two… Expand
Sustained and transient covert attention enhance the signal via different contrast response functions
- S. Ling, M. Carrasco
- Psychology, Medicine
- Vision Research
- 1 April 2006
We investigated the mechanisms underlying the effects of sustained and transient covert attention on contrast sensitivity. The aim of this study was twofold: (1) Using a zero-noise display, we… Expand
Perceptual Learning Selectively Refines Orientation Representations in Early Visual Cortex
- Janneke F. M. Jehee, S. Ling, Jascha D. Swisher, R. S. van Bergen, F. Tong
- Psychology, Medicine
- The Journal of Neuroscience
- 21 November 2012
Although practice has long been known to improve perceptual performance, the neural basis of this improvement in humans remains unclear. Using fMRI in conjunction with a novel signal detection-based… Expand
When sustained attention impairs perception
- S. Ling, M. Carrasco
- Psychology, Medicine
- Nature Neuroscience
- 10 September 2006
Virtually all behavioral and neurophysiological studies have shown that sustained (endogenous, conceptually driven) attention enhances perception. But can this enhancement be held indefinitely? We… Expand
A population-coding model of attention’s influence on contrast response: Estimating neural effects from psychophysical data
- F. Pestilli, S. Ling, M. Carrasco
- Psychology, Medicine
- Vision Research
- 2 June 2009
Human psychophysics and monkey physiology studies have shown that attention modulates early vision - contrast sensitivity and processing. But how can we bridge the effects of attention on perceptual… Expand
Transient covert attention does alter appearance: A reply to Schneider (2006)
- S. Ling, M. Carrasco
- Psychology, Medicine
- Perception & psychophysics
- 1 August 2007
We recently demonstrated that transient covert attention increases the apparent contrast of a stimulus (Carrasco, Ling, & Read, 2004). Schneider (2006) proposes that the observed increase in apparent… Expand
Attention alters orientation processing in the human lateral geniculate nucleus
Orientation selectivity is a cornerstone property of vision, commonly believed to emerge in the primary visual cortex. We found that reliable orientation information could be detected even earlier,… Expand
Transient attention does increase perceived contrast of suprathreshold stimuli: A reply to Prinzmetal, Long, and Leonhardt (2008)
- M. Carrasco, Stuart Fuller, S. Ling
- Psychology, Medicine
- Perception & psychophysics
- 1 October 2008
Carrasco, Ling, and Read (2004) showed that transient attention increases perceived contrast. However, Prinzmetal, Long, and Leonhardt (2008) suggest that for targets of low visibility, observers may… Expand
