Reversal Learning

11.

Defining the neural mechanisms of probabilistic reversal learning using event-related functional magnetic resonance imaging.

Event-related functional magnetic resonance imaging was used to measure blood oxygenation level-dependent responses in 13 young healthy human volunteers during performance of a probabilistic reversal-learning task. The task allowed the separate ...

Response scale transfer for visual speed.

By reversing the presentation order and frequency of stimuli between two series of trials, we studied how the category scale for visual speed is transferred across stimulus contexts. Participants judged five stimulus speeds, using three categories (slow, ...

Learning, retention and generalization of a mirror tracing skill in Alzheimers disease.

The present study examined the ability of 12 patients with probable Alzheimers disease (AD) and 12 age- and education-matched normal control (NC) subjects to learn and retain the visuomotor skills necessary to efficiently trace a pattern (e.g., a 4- or ...

Neurocognitive function and joint attention ability in young children with autism spectrum disorder versus developmental delay.

Studies have shown that young children with autism are not impaired on prefrontal tasks relative to what would be expected for their mental age, raising questions about the executive dysfunction hypothesis of autism. These studies did not include ...

Stability of functional equivalence and stimulus equivalence: effects of baseline reversals.

Functional equivalence and stimulus equivalence classes were established, reversed, and tested for stability with college students. Functional stimulus classes were established using a task in which students were trained to say nonsense words in the ...
