Hajime Otani has been at Central Michigan University since 1989, the year he received his Ph.D. in Experimental Psychology from the University of Georgia.

Research Interest:

Dr. Otani has been investigating basic processes of human memory and cognition. In particular, he has been interested in basic mechanisms of encoding and retrieval. To investigate the mechanisms, he has been examining various memory phenomena, such as hypermnesia, word frequency effects, feeling of knowing, and prospective memory, and how these phenomena are affected by various encoding methods. Recently, he has also developed an interest in cognitive aging. He plans to test older adults to find out how basic cognitive mechanisms change as one ages. He is also examining how basic processes of memory and cognition are affected by neuro-degenerative diseases such as Huntington's and Alzheimer's diseases.
