ABSTRACT
The physical study of infancy has given rich rewards in the past fifty years, and it might well be that a similar interest in emotional development would produce rewards even more rich. In psychological matters is a tendency towards development which is innate, and which corresponds to the growth of the body and the gradual development of functions. Independence is something that is achieved out of dependence, but it is necessary to add that dependence is achieved out of what might be called double dependence. The achievement of a degree of independence may quite normally be lost and regained over and over-again, and often an infant may return to dependence after being markedly independent at one year. Integration appears to be linked with the more definite emotional or affective experiences, such as rage, or the excitement of a feeding situation.
