Since the establishment of the first preschool psychological laboratory in 1921, the Iowa Child Welfare Research Station has been conducting, as one part of the program in the mental development of young children, a series of experiments that have been repeated, extended and amplified from year to year. These experiments have been planned to afford detailed analyses of performance and the evaluation of psychological processes rather than test standards or the clinical diagnosis of a particular child.
