Katrina N. Rhymer, Ph.D. received her Ph.D. in School Psychology from Mississippi State University in 2000. She completed her internship at the Houston Independent School District in Houston, TX. She has been at Central Michigan University since 2000. She has been a Licensed Psychologist in the state of Michigan since 2008.
My research involves examining academic interventions used with children. The majority of my research has involved examining the explicit timing intervention and the interspersal intervention for mathematics. Currently, we are investigating the relationship between empirically-validated academic interventions and general anxiety, test anxiety, and math anxiety.
