TO EXPLORE THE NATURE OF THE LEARNING PROCESS, THREE IMPORTANT PROBLEM AREAS WERE STUDIED. STUDIES IN THE FIRST AREA, ATTITUDINAL AND AFFECTIVE SKILLS, ARE CONCERNED WITH INDUCING A CHILD TO LEARN AND SUSTAINING HIS ATTENTION. STUDIES IN THE SECOND AREA, COGNITIVE SKILLS, SOUGHT TO DISCOVER WHETHER GENERAL IDEAS AND SKILLS CAN BE LEARNED IN SUCH A WAY IN ONE SUBJECT THAT THEY WILL MATERIALLY AFFECT PROGRESS IN ANOTHER. STUDIES IN THE THIRD AREA, STIMULUS CONTROL, ARE CONCERNED WITH PRESENTING LEARNING MATERIALS IN AN OPTIONAL SEQUENCE. WORKING PAPERS AND NOTES ON THE PLENARY SESSIONS ARE APPENDED. THIS MONOGRAPH PRESENTS THE RESULTS OF THE WORKING CONFERENCE ON RESEARCH ON CHILDREN'S LEARNING (CAMBRIDGE, MASS., JUNE 14-28, 1963).
