Current Research Efforts:

Adaptive Experimental Design: Experimentation is fundamental to the advancement of psychological science. One of the greatest challenges in model comparison is designing an experiment that clearly distinguishes between models. In design optimization, we are interested in identifying an experimental design under which the experiment is likely to produce the most differentiating outcomes between the models under consideration in some defined sense. For example, in designing an experiment investigating whether the rate of forgetting over time follows a power curve or an exponential curve, the experimenter must determine “optimally” the values of time intervals between the study and test sessions. Recent developments in sampling-based Monte Carlo methods in Bayesian statistics make it possible to determine these values and thereby identify an optimal design. The work has been supported by the National Institute of Mental Health.
