Much recent evidence suggests some dramatic differences in the way people learn
perceptual categories, depending on exactly how the categories were constructed. Four …

Visual perceptual learning (VPL) is long-term performance increase resulting from visual
perceptual experience. Task-relevant VPL of a feature results from training of a task on the …

The dominant paradigm for inference in psychology is a null-hypothesis significance testing
one. Recently, the foundations of this paradigm have been shaken by several notable …

Visual perceptual learning through practice or training can significantly improve
performance on visual tasks. Originally seen as a manifestation of plasticity in the primary …

Reports published in Vision Research during the late years of the 20th century described
surprising effects of long-term sensitivity improvement with some basic visual tasks as a …

To investigate the nature of plasticity in the adult visual system, perceptual learning was
measured in a peripheral orientation discrimination task with systematically varying amounts …

The field of perceptual learning has identified changes in perceptual templates as a
powerful mechanism mediating the learning of statistical regularities in our environment. By …

Humans have the metacognitive ability to judge the accuracy of their own decisions via
confidence ratings. A substantial body of research has demonstrated that human …

Visual perceptual learning (VPL) is defined as a long-term improvement in performance on a
visual task. In recent years, the idea that conscious effort is necessary for VPL to occur has …

This study aimed to identify neural mechanisms that underlie perceptual learning in a visual-
discrimination task. We trained two monkeys (Macaca mulatta) to determine the direction of …
