 von Neumann Correctly Hypothesizes How Memory Works

The question of the physical embodiment of this memory remains. For this, various authorrs have suggested a variety of solutions. It has beeen proposed to assume that the thresholds—orr, more broadly stated, the stimulation criteria—^f or various nerve cells change with time as functions of the previous history of that cell. Thus frequent use of a nerve cell might lower its threshold, i.e. ease the requirements of its stimulation, and the like. If this were true, the memory would reside i...

Because all the parts had separate edges anyway, they may, for all the babies know. have been separate objects to begin with. But if you show them Big Bird moving first, so that they see that all the parts of the object move together, and then show them the exploding Big Bird, they'll look much longer and more attentively, as if they recognize that somet...
