The Psychology department held a symposium on child development and education in honor of Professor L. Joseph Stone, who died in December of 1975. The keynote speaker, Jerome Kagan of Harvard lectured on “The Human Infant: Origin, Transition, and Competent Agent.” Kagan asserted that a child’s development did not occur on a continuum but instead was “discontinuous” and punctuated by “major growth jumps.”      The Miscellany News

Like Professor Stone, Kagan was a pioneer in developmental psychology.  His Personal Development was published in 1971, and The Growth of the Child: Reflections on Human Development, appeared in 1978.
