ABSTRACT

Allow me to make a brief comparison between the genetic influences on intellectual activities in two different phases of early development (the anal phase and the early part of latency), in amplification of remarks I made yesterday during the sectional discussions. Since traumata suffered in the anal phase are often followed by traumata in early latency, we may find that the ultimate disturbances may stem from both phases. It might nevertheless be useful to try to distinguish them, even if somewhat schematically.
