In the 1st expt the order of presentation of the stimulus-words in the typical word-number situation was systematically varied. The prediction of a descending gradient after reward following from the guessing-sequence hypothesis was borne out. No other statistically acceptable gradient effects were uncovered in the performance of 40 subjects. The 2d study involved an analysis of "randomly" guessed numbers. It was found that, college students exhibited pronounced tendencies to guess numbers sequentially. More than two thirds of the responses of 77 subjects fell within the limits of plus or minus 2 units of the preceding number guessed. Rarely did the same number follow itself. This evidence is interpreted as definitely ascribing the after-gradient of the "spread of effect" to number-guessing habits.
