required that spades be thrown to diamond boxes, diamonds to 

 dub boxes, and clubs and hearts each be distributed to boxes 

 bearing their own labels, i.e., clubs and hearts were "resident," 

 each card being thrown to a box bearing its number. Since 

 spade boxes were not used, only 39 of the 52 labelled boxes were 

 involved in the investigation. The order of the suit was : clubs, 

 diamonds, spades, hearts (referred to as C, D, S, H); and the 

 numerical order was: Q, 5, 6, 4, 3, 10, 8, 2, K, 9, 7, J, A. Two 

 subjects, D and K distributed C to H, and H to S, and S and D to 

 their respective boxes using only 39 boxes of the case. The 

 order of the suit was identical with that of plan I, but the numeri- 

 cal order ran 10, 8, 6, Q, 5, K, 7, A, J, 9, 4, 2, 3, This formed 

 plan II. Subjects A, B, and C in plan I, and D in plan II, were 

 given pleasant stimuli; subjects E, F, G, and H, plan I, received 

 unpleasant stimuli, while subjects I and J plan I and K, plan II, 

 worked under normal conditions. The 8 stimuli subjects were 

 given their respective stimuli at every other period, beginning 

 with the third; normal periods then, alternated with stimuli 

 periods, the latter always occurring on the odd number. Five 

 distributions were made by all subjects at each period (one hour) 

 except with the first six periods. At the first period, owing to 

 the novelty of the situation and to the difficulty of grasping the 

 instructions, only from one to two distributions were made. 

 The number gradually increased up to the sixth period, when it 

 became evident that all subjects were able to make five records 

 per period (one hour). The amount of practice permitted during 

 the first six periods was governed by the progress of the slowest 

 subjects. The stimuli applied to the four senses, while not al- 

 ways given in the same order, were presented in a cumulative 

 fashion, e.g., before the first distribution, odors and tastes; be- 

 fore the second, odors, tastes and sound; before the third, odors, 

 tastes, sounds and pictures : and all four kinds were given before 

 the fourth and fifth trials. A trial consisted in delivering the pack 

 of 52 cards to the boxes according to the plan already indicated. 

 A distribution comprised five phases: (1) the subject was given 

 the stimulus; (2) he took the deck of cards as hi the act of distri- 

 bution and stood directly in front of the case; (3) the signal
