Excerpt from Sensory Discrimination in Normal, and Feeble Minded Children A real and growing need is felt at present for information concerning the mental differences of rmals and defectives1 of the same mental but of different chrological ages. The typical defective is insipid, barren of original ideas, lacking in inhibition, poor in judgment, with intellectual curiosity, and his accomplishments arc the results of prolonged training and experience. The rmal child of the same mental age is original, inquisitive, vivacious, full of initiative. As Binet aptly expresses it (1, p. 122): The impression that is obtained when one passes some time with an imbecile or an idiot is that they are literally les pauvres d'esprit. They do t differ from rmals in the same way as do certain types of dements by unexpected and sometimes unique and bizarre phemena, which are like extra attachments to an already kwn mechanism; the difference is t one of more but of less. The defective is a rmal who lacks something. But what is the nature of this defect? If ever the idea of higher and lower processes had an opportunity for application in psychology, it is certainly among the individuals of this species. One feels that it is especially the higher part of the intelligence, the finest and the most delicate that has t developed in them. They are reduced to the coarsest and therefore the simplest, the most elementary, the most general in man.
