Perceptual learning improves contrast sensitivity of V1 neurons in cats

T Hua, P Bao, CB Huang, Z Wang, J Xu, Y Zhou, ZL Lu - Current biology, 2010 - cell.com
Background Perceptual learning has been documented in adult humans over a wide range

Economic value biases uncertain perceptual choices in the parietal and prefrontal cortices

C Summerfield, E Koechlin - Frontiers in human neuroscience, 2010 - frontiersin.org
An observer detecting a noisy sensory signal is biased by the costs and benefits associated
with its presence or absence. When these costs and benefits are asymmetric, sensory, and …

Ideal observer analysis of crowding and the reduction of crowding through learning

GJ Sun, STL Chung, BS Tjan - Journal of vision, 2010 - jov.arvojournals.org
Crowding is a prominent phenomenon in peripheral vision where nearby objects impede
one's ability to identify a target of interest. The precise mechanism of crowding is not known …

[HTML][HTML] Spatially extensive summation of contrast energy is revealed by contrast detection of micro-pattern textures

TS Meese - Journal of vision, 2010 - iovs.arvojournals.org
Vision must analyze the retinal image over both small and large areas to represent fine-
scale spatial details and extensive textures. The long-range neuronal convergence that this …

Perspectives on modeling in cognitive science

RM Shiffrin - Topics in cognitive science, 2010 - Wiley Online Library
This commentary gives a personal perspective on modeling and modeling developments in
cognitive science, starting in the 1950s, but focusing on the author's personal views of …

Information-limited parallel processing in difficult heterogeneous covert visual search.

BA Dosher, S Han, ZL Lu - Journal of Experimental Psychology …, 2010 - psycnet.apa.org
Difficult visual search is often attributed to time-limited serial attention operations, although
neural computations in the early visual system are parallel. Using probabilistic search …

Shared mechanisms of perceptual learning and decision making

CT Law, JI Gold - Topics in cognitive science, 2010 - Wiley Online Library
Perceptual decisions require the brain to weigh noisy evidence from sensory neurons to
form categorical judgments that guide behavior. Here we review behavioral and …
