Dr. Bellezza is not accepting new graduate students.

Dr. Bellezza's main area of research involves applying general-processing-tree (multinomial) models to explaining the functioning of human memory. These mathematical techniques allow research to analyze complex behavior into basic cognitive mechanisms retrieval of information from memory and decision-making. Remembering is a mix of storing information, retrieving incomplete information from memory, and making decisions and judgments based on typically incomplete information.

Dr. Bellezza's multinomial model is the basis of a recent grant proposal that explores deterioration in memory as part of the aging process. Preliminary data show a good fit of the multinomial model with younger adults, and the proposal extends these findings to older adults. Specific predictions have been made that test the viability of the multinomial model versus other models that have been applied to understand memory decrements in older adults.
