Emeritus Associate Professor, Behavioral Neurosciences


Recipient of OSU Department of Psychology Distinguished Teaching Award (2000)

Following her undergraduate education in 1973, Collier received graduate training in developmental psychobiology at Princeton University in 1974 and her Ph.D. in learning and motivation from the University of Washington in 1976. Collier also received training in behavioral medicine during a sabbatical year at Wright State University in 1987. She has served as a grant review panel member for the National Institute of Mental Health, and as consulting editor for the American Psychological Association's Journal Supplement Abstract Service. Her research focus has been in the area of animal learning, motivation, and memory. An integrating theme in her work has been on species- and age-dependent considerations in assessing animal cognitive and memorial processes, particularly in aversive, stressful contexts in early development. A rat animal model is used in her research because such a model permits enhanced control of early experiences, allows easier assessment of the entire developmental period because the rat is a rapidly maturing organism, and provides for interventions that potentially permit investigations of the underlying mechanisms supporting learning. Collier's current work involves investigations of the correlates of arousal and learning in infants, and how the mother, an important component of the young organism's milieu, modulates arousal during infant learning.
