Research statement

By bridging psychometric theory and methods with cognitive psychology using computer technologies, I have been involved in expanding item response theory (latent trait models). I have also proposed new families of mathematical models, called the acceleration model, the logistic positive exponent family of models, etc., as well as the competency space approach to cognitive assessment. These models can be utilized to clarify many issues in cognitive psychology.
