Signal but not noise changes with perceptual learning by Bennett, P. J, Gold, J, Sekuler, A. B

“…Perceptual discrimination improves with practice. This 'perceptual learning' is often specific to the stimuli presented during training, indicating that…”

Sound alters visual motion perception by Sekuler, Robert, Sekuler, Allison B, Lau, Renee

“…Little is known about how complementary inputs from different senses are coordinated. To explore the perceptual consequences of this coordination, we devised…”

Identification of band-pass filtered letters and faces by human and ideal observers by Gold, Jason, Bennett, Patrick J., Sekuler, Allison B.

“…To better understand how the visual system makes use of information across spatial scales when identifying different kinds of complex patterns, we measured…”

Corticolimbic Interactions Associated with Performance on a Short-Term Memory Task Are Modified by Age by Della-Maggiore, Valeria, Sekuler, Allison B, Grady, Cheryl L, Bennett, Patrick J, Sekuler, Robert, McIntosh, Anthony R

“…Aging has been associated with a decline in memory abilities dependent on hippocampal processing. We investigated whether the functional interactions between…”

Recruitment of unique neural systems to support visual memory in normal aging by McIntosh, A.R., Sekuler, A.B., Penpeci, C., Rajah, M.N., Grady, C.L., Sekuler, R., Bennett, P.J.

“…The performance of many cognitive tasks changes in normal aging [1–3]. Recent behavioral work has identified some tasks that seem to be performed in an…”

Effects of Aging on the Useful Field of View by SEKULER, A. B, BENNETT, P. J, MAMELAK, M

“…Previous research has shown that the useful field of view (UFOV) is a useful tool in predicting driving ability, and the UFOV also seems to decline with age…”

Spatial characteristics of center-surround antagonism in younger and older adults by Betts, Lisa R, Sekuler, Allison B, Bennett, Patrick J

“…Sensitivity to motion direction is affected by stimulus size, contrast (D. Tadin & J. S. Lappin, 2005; D. Tadin, J. S. Lappin, L. A. Gilroy, & R. Blake, 2003),…”

Collisions between Moving Visual Targets: What Controls Alternative Ways of Seeing an Ambiguous Display? by Sekuler, Allison B, Sekuler, Robert

“…When identical visual targets move directly toward and then past one another, they appear either to stream past one another or to bounce off each other…”

Motion and shape in common fate by Uttal, William R, Spillmann, Lothar, Stürzel, Frank, Sekuler, Allison B

“…We determined how much motion coherence was needed to detect a target group of four moving dots in a dynamic visual noise (DVN) background. The lifetimes of…”

Local and global minima in visual completion: effects of symmetry and orientation by Sekuler, A B

“…The visual information that specifies three-dimensional objects is often incomplete because objects occlude parts of themselves and other objects. Yet people…”

Peripheral spatial vision: limits imposed by optics, photoreceptors, and receptor pooling by Banks, M S, Sekuler, A B, Anderson, S J

“…We examined the contribution of optical and photoreceptor properties as well as receptor pooling to eccentricity-dependent variations in spatial vision by…”

Interactions between symmetry and elongation in determining reference frames for object perception by Sekuler, A B, Swimmer, M B

“…Many theories of object recognition posit that objects are encoded with respect to a perceptual frame of reference. Such theories assume that factors such as…”

Simple-pooling of unidirectional motion predicts speed discrimination for looming stimuli by Sekuler, A B

“…Looming objects comprise many 2D unidirectional motion elements changing over time. However, observers assign a single 3D speed to looming objects, not many…”

Deriving behavioural receptive fields for visually completed contours by Gold, Jason M, Murray, Richard F, Bennett, Patrick J, Sekuler, Allison B

“…The visual system is constantly faced with the problem of identifying partially occluded objects from incomplete images cast on the retinae…”

Representational development of direction in motion perception: a fragile process by Sekuler, A B, Sekuler, R

“…Response to a change in direction is more rapid if the target moves in a predictable direction before the change than if the pre-change direction is not…”

The effects of occlusion and past experience on the allocation of object-based attention by Pratt, J, Sekuler, A B

“…There is considerable evidence indicating that cuing a specific portion of an object results in the entire object's being attended to. In the present study, we…”

Effects of aging on calculation efficiency and equivalent noise by Bennett, P J, Sekuler, A B, Ozin, L

“…Contrast sensitivity under photopic conditions declines with age; however, the cause of this decline remains unknown. To address this issue, we measured…”

Motion segregation from speed differences: evidence for nonlinear processing by Sekuler, A B

“…This paper examines observers' ability to detect regions delimited by speed differences. Several types of translational motion stimuli, of varying task…”

How the visual system detects changes in the direction of moving targets by Sekuler, A B, Sekuler, R, Sekuler, E B

“…To determine how the visual system represents information about change in target direction, we studied the detection of such change under conditions of varying…”

Time course of amodal completion revealed by a shape discrimination task by Murray, R F, Sekuler, A B, Bennett, P J

“…We measured the extent of amodal completion as a function of stimulus duration over the range of 15-210 msec, for both moving and stationary stimuli…”
