THIS manual is designed to meet the requirements for a series of individual experiments in the first course in psychology. It makes individual experiments, as opposed to class demonstrations, practicable, regardless of laboratory facilities or the size of the class. The student is given means and encouragement for pursuing each problem intensively in order that he may acquire independence of thought and action, realize the actuality of mental processes, and get here and there a vision of the vastness, the orderliness, the practical significance, and the charms of mental life.
No laboratory facilities are required. In this there is a triple gain: it saves the manifolding of equipment, it frees the student from the technicalities incidental to the manipulation of apparatus at a time when his energies need to be conserved for the grasping of the psychological problem, and it saves time for the class period, the experiments being adapted for outside assignments. The apparatus other than that ordinarily at the disposal of students is supplied with the book in the accompanying envelope.*____________________
