Neuropsychology of Perceptual Category Learning 1 The Neuropsychology of Perceptual Category Learning
There is widespread agreement that multiple qualitatively different category learning systems mediate the learning of different category structures. Two systems that have received support are (1) a frontal-based explicit system that uses logical reasoning, depends on working memory and executive attention, and is mediated primarily by the anterior cingulate, the prefrontal cortex, and the assoc...
متن کاملStimulus Modality and Perceptual Category Learning 1 Stimulus Modality Interacts with Category Structure in Perceptual Category Learning
Two experiments were conducted that examined information-integration and rule-based category learning using stimuli that contained auditory and visual information. Results suggest that it is easier to perceptually integrate information within these sensory modalities than across modalities. Conversely, it is easier to perform a disjunctive rule-based task when information comes from different s...

متن کاملWhen does fading enhance perceptual category learning?
Training that uses exaggerated versions of a stimulus discrimination (fading) has sometimes been found to enhance category learning, mostly in studies involving animals and impaired populations. However, little is known about whether and when fading facilitates learning for typical individuals. This issue was explored in 7 experiments. In Experiments 1 and 2, observers discriminated stimuli bas...
متن کاملCategory learning and perceptual categorization in schizophrenia.
The aim of this study was to evaluate category learning in schizophrenia on tests of perceptual abstraction. Participants learned to categorize simple geometrical shapes. The categories were either well-defined (discrete categories, or DCs) or ill-defined (graded categories, or GCs). In DCs, the cues defining category membership can be verbalized in an all-or-none fashion, while in GCs they can...
