An award-winning playwright, a psychologist interested in memory who helped found the discipline of cognitive psychology and an authority on elephant and whale communication are among the guest speakers in a Monday afternoon lecture series on memory and creativity to be offered this spring at Cornell.

The Feb. 9 and March 30 lectures have been reversed since the original announcement to accommodate the lecturers' schedules.

The lectures, which are free and open to the public, are part of an English department undergraduate course, "Mind and Memory: Explorations of Creativity in the Arts and Sciences," co-directed by Diane Ackerman and James McConkey. Ackerman is a well-known poet and naturalist, and author of A Natural History of the Senses. McConkey is a novelist and essayist, author of Court of Memory and the Goldwin Smith Professor of English Emeritus at Cornell.

Except for the week of spring recess, the lectures will be offered on consecutive Mondays beginning Jan. 26 and will be held from 2:55 to 4:10 p.m. in Hollis Cornell Auditorium in Goldwin Smith Hall.
