Statistical learning has been studied as a mechanism by which people automatically and implicitly learn patterns in the environment. Here, we sought to examine general assumptions about statistical learning, including whether the learning is long-term, and whether it can occur implicitly. We exposed participants to a stream of stimuli, then tested them(More)
Perceptual learning in adult humans and animals refers to improvements in sensory abilities after training. These improvements had been thought to occur only when attention is focused on the stimuli to be learned (task-relevant learning) but recent studies demonstrate performance improvements outside the focus of attention (task-irrelevant learning). Here,(More)
How is development of cortical maps in V1 coordinated across cortical layers to form cortical columns? Previous neural models propose how maps of orientation (OR), ocular dominance (OD), and related properties develop in V1. These models show how spontaneous activity, before eye opening, combined with correlation learning and competition, can generate maps(More)
This thesis addresses the problem of synthesizing images of real scenes under three-dimensional transformations in viewpoint and appearance. Solving this problem enables interactive viewing of remote scenes on a computer, in which a user can move a virtual camera through the environment and virtually paint or sculpt objects in the scene. It is demonstrated(More)
Drawing a box around an intended segmentation target has become both a popular user interface and a common output for learning-driven detection algorithms. Despite the ubiquity of using a box to define a segmentation target, it is unclear in the literature whether a box is sufficient to define a unique segmentation or whether segmentation from a box is(More)
Multisensory perception has been the focus of intense investigation in recent years. It is now well-established that crossmodal interactions are ubiquitous in perceptual processing and endow the system with improved precision, accuracy, processing speed, etc. While these findings have shed much light on principles and mechanisms of perception, ultimately it(More)
Perceptual learning (PL), the improvement of perceptual skills through practice, is known to be variably affected by the presence of external guidance, depending on the task. In various perceptual tasks, trial-by-trial feedback enhances learning and in some cases it is even necessary to induce learning. However, in some cases PL occurs just as well with(More)
Impaired auditory-phonological processing is widely assumed to characterize dyslexic individuals. However, the magnocellular-dorsal (MD) pathway deficit theory, while controversial, has long been argued to play an important role in developmental dyslexia. The debate has centered on the critique that the visual MD deficit found in individuals with(More)
