Unsupervised Category Learning With Integral-Dimension Stimuli, Shawn W. Ell, Gregory F. Ashby, Steven B. Hutchinson
Psychology Faculty Scholarship
Despite the recent surge in research on unsupervised category learning, the majority of studies have focused on unconstrained tasks in which no instructions are provided about the underlying category structure. Relatively little research has focused on constrained tasks in which the goal is to learn pre-defined stimulus clusters in the absence of feedback. The few studies that have addressed this issue have focused almost exclusively on stimuli for which it is relatively easy to attend selectively to the component dimensions (i.e., separable dimensions). In the present study, we investigated the ability of participants to learn categories constructed from stimuli for …

The Possible Connection Of Gamma Oscillation And 3-D Object Representation, Thien N. Vu
The Possible Connection Of Gamma Oscillation And 3-D Object Representation, Thien N. Vu
Summer Research
We process and encode for different features of a particular object (shape, color, texture, etc.) in distinct areas of the brain. How we bind these attributes together into a unified perception of an object is unknown. Past research suggests that synchronized activity between brain areas, particularly induced gamma activity (~ 40 Hz), may account for this binding process and the basis of our conscious perceptual experience, specifically through object representation. In this study, participants were asked to look at a series of 2-D pictures of cars from distinctive rotations (00, 900, 1800) and were …

Feeling At Home: Learning, Law, Cognitive Science, And Narrative, Lea B. Vaughn

What is the "how and why" of law's affinity for narrative? In order to explain why the use of stories is such an effective teaching and presentation strategy in the law, this paper will consider theories and accounts from cognitive as well as evolutionary psychology, neuroscience, and, briefly, cultural anthropology. This account seeks to address "how" narrative helps us learn and use the law as well as "why" we are so compelled to use stories in teaching and in practice.
Brain science, simplified here, suggests that the first task is to grab someone's attention. Emotionally charged events are more likely …
