Interest Areas

Dr. Guerin is an Associate Director of the Fullerton Longitudinal Study (FLS), a collaborative research effort initiated by Allen W. Gottfried in the CSUF Department of Psychology in 1978. The FLS team has charted the development of over 100 children and their families from the children’s first birthday through 38 years. The FLS is internationally known and cited widely in developmental psychology and child development textbooks. Dr. Guerin’s specific research activities focus on the developmental correlates of children’s temperament and intellectual development.
