The cognitive neuroscience of implicit category learning
There is much recent interest in the question of whether people have available a single category learning system or a number of qualitatively different systems. Most proponents of multiple systems have hypothesized an explicit, rule-based system and some type of implicit system. Although there has been general agreement about the nature of the explicit system, there has been disagreement about ...
متن کاملMultiple Systems of Perceptual Category Learning: Theory and Cognitive Tests
The COVIS (COmpetition between Verbal and Implicit Systems) theory of category learning (Ashby, Alsonso-Reese, Turken, & Waldron, 1998) postulates two systems that compete throughout learning – a frontal-based explicit system that uses logical reasoning and depends on working memory and executive attention, and a basal ganglia-mediated implicit system that uses procedural learning. The implicit...
متن کاملIncreased Cognitive Load Enables Unlearning in Procedural Category Learning
Interventions for drug abuse and other maladaptive habitual behaviors may yield temporary success, but are often fragile and relapse is common. This implies that current interventions do not erase or substantially modify the representations that support the underlying addictive behavior — that is, they do not cause true unlearning. One example of an intervention that fails to induce true unlear...
متن کاملCognitive Models of Test-Item Effects in Human Category Learning
Imagine two identical people receive exactly the same training on how to classify certain objects. Perhaps surprisingly, we show that one can then manipulate them into classifying some test items in opposite ways, simply depending on what other test items they are asked to classify (without label feedback). We call this the Test-Item Effect, which can be induced by the order or the distribution...
متن کاملCategory use and category learning.
Categorization models based on laboratory research focus on a narrower range of explanatory constructs than appears necessary for explaining the structure of natural categories. This mismatch is caused by the reliance on classification as the basis of laboratory studies. Category representations are formed in the process of interacting with category members. Thus, laboratory studies must explor...
