Visual imagery has been closely linked to brain mechanisms involved in perception. Can
visual imagery, like visual perception, improve by means of training? Previous research has …

What is learned during perceptual learning? We address this question by analyzing how
perceptual inefficiencies improve over the course of perceptual learning (Dosher & Lu …

The human ability to introspect on thoughts, perceptions or actions− metacognitive ability−
has become a focal topic of both cognitive basic and clinical research. At the same time it …

After encoding, memory traces are fragile and easily disrupted by new learning until they are
stabilized through a process termed consolidation,. However, several studies have …

Maximizing rewards per unit time is ideal for success and survival in humans and animals.
This goal can be approached by speeding up behavior aiming at rewards and this is done …

Integration of sensory signals that emanate from the same source, such as the visual of lip
articulations and the sound of the voice of a speaking individual, can improve perception of …

The belief that learning can be modulated by social context is mainly supported by high-
level value-based learning studies. However, whether social context can even modulate low …

Translating noisy sensory signals to perceptual decisions is critical for successful
interactions in complex environments. Learning is known to improve perceptual judgments …

Adult amblyopes can improve positional acuity through practice; however, the neural
mechanisms underlying this improvement are still not clear. In this study, seven adult …

The role of feedback in perceptual learning is probed in an orientation discrimination
experiment under destabilizing non-stationary conditions, and explored in a neural-network …
