Blood oxygenation level-dependent contrast response functions identify mechanisms of covert attention in early visual areas
- X. Li, Z. Lu, B. Tjan, B. Dosher, Wilson Chu
- Medicine
- Proceedings of the National Academy of Sciences
- 22 April 2008
Covert attention can lead to improved performance in perceptual tasks. The neural and functional mechanisms of covert attention are still under investigation. Using both rapid event-related and mixed… Expand
Human efficiency for recognizing 3-D objects in luminance noise
- B. Tjan, W. L. Braje, G. Legge, D. Kersten
- Psychology, Medicine
- Vision Research
- 1 November 1995
The purpose of this study was to establish how efficiently humans use visual information to recognize simple 3-D objects. The stimuli were computer-rendered images of four simple 3-D objects--wedge,… Expand
Rapid and Persistent Adaptability of Human Oculomotor Control in Response to Simulated Central Vision Loss
- M. Kwon, Anirvan S. Nandy, B. Tjan

- Current Biology
- 9 September 2013
The central region of the human retina, the fovea, provides high-acuity vision. The oculomotor system continually brings targets of interest into the fovea via ballistic eye movements (saccades).… Expand
Spatial-frequency characteristics of letter identification in central and peripheral vision
Spatial-frequency characteristics of letter identification are much better understood in the fovea than in the periphery. The purpose of this study was to compare the spatial-frequency… Expand
Saccade-confounded image statistics explain visual crowding
- Anirvan S. Nandy, B. Tjan

- Nature Neuroscience
- 8 January 2012
Processing of shape information in human peripheral visual fields is impeded beyond what can be expected by poor spatial resolution. Visual crowding, the inability to identify objects in clutter, has… Expand
What makes faces special?
- Xiaomin Yue, B. Tjan, I. Biederman
- Psychology, Medicine
- Vision Research
- 1 October 2006
What may be special about faces, compared to non-face objects, is that their neural representation may be fundamentally spatial, e.g., Gabor-like. Subjects matched a sequence of two filtered images,… Expand
Viewpoint Dependence in Visual and Haptic Object Recognition
- F. Newell, M. Ernst, B. Tjan, H. Bülthoff
- Psychology, Medicine
- Psychological science
- 1 January 2001
On the whole, people recognize objects best when they see the objects from a familiar view and worse when they see the objects from views that were previously occluded from sight. Unexpectedly, we… Expand
The Perception of a Face Is No More Than the Sum of Its Parts
When you see a person’s face, how do you go about combining his or her facial features to make a decision about who that person is? Most current theories of face perception assert that the ability to… Expand
The nature of letter crowding as revealed by first- and second-order classification images.
- Anirvan S. Nandy, B. Tjan
- Psychology, Medicine
- Journal of vision
- 7 February 2007
Visual crowding refers to the marked inability to identify an otherwise perfectly identifiable object when it is flanked by other objects. Crowding places a significant limit on form vision in the… Expand
