I am grateful to the many Faculty and Student Awards page 10 dedicated faculty, staff, and students who made it a fun Faculty News and rewarding year. It is a great honor to be head of this page 13 excellent and congenial department and I have found Alumni News page 15 the experience to be both stimulating and rewarding. The field of psychology has changed a great deal since most of us were in school. Our department now consists of eight different areas or divisions: Biological, Brain and Cognition, Clinical/Community, Cognitive, Developmental, Quantitative, Social-Personality-Organizational, and Visual Cognition and Human Performance. Students and faculty members in these divisions study the mind and behavior at various levels of analysis— from individual neurons, to individual brains, to individual people, to groups, to institutions. In terms of size, we are one of the largest departments on campus with approximately 60 tenure-stream faculty members, nearly 200 graduate students, and approximately 1,300 undergraduate majors. We teach over 50,000 student credit hours each year, and we do it well—80 percent of our teaching ratings are PSYCHOLOGY TImeS Psychology Times is a publication of the above the midpoint of our five-point rating scale.
