The capability of the adult primate visual system for rapid and accurate recognition of targets
in cluttered, natural scenes far surpasses the abilities of state-of-the-art artificial vision …

Seeking to understand how people recognize objects, we have examined how they identify
letters. We expected this 26-way classification of familiar forms to challenge the popular …

Whereas much is known about the visual shape selectivity of neurons in the inferior
temporal cortex (ITC), less is known about the role of visual learning in the development and …

A large body of data suggests that phonological deficits play an important causal role in
dyslexics' reading difficulties. The functional role of visual impairments is still highly debated …

External noise paradigms, measuring contrast threshold as a function of external noise
contrast (the “TvC” function), provide a valuable tool for studying perceptual mechanisms …

The job of any sensory system is to create objects in the world out of the incoming proximal
stimulus energy. The energy is neutral; it does not specify the objects itself. Thus, sensory …

In this study, we applied the external noise method and the PTM model to identify
mechanisms underlying performance deficits in amblyopia. Amblyopic and normal …

Dosher and Lu (1998)[Perceptual learning reflects external noise filtering and internal noise
reduction through channel reweighting. Proceedings of the National Academy of Sciences of …

Perceptual learning is an improvement in perceptual task performance reflecting plasticity in
the perceptual system. Practice effects were studied in two object orientation tasks: a first …

The way in which input noise perturbs the behavior of a system depends on the internal
processing structure of the system. In visual psychophysics, there is a long tradition of using …
