One of my pupils hascontrived a similar arrangement for measuring how fastH9wfastadog a dog thinks. The general plan is shown in Fig. results cannot yet be made public, as it is the ruleof the laboratory to let the experimenter speak the New Haven experiments the school children Time of dis-crimination andchoice as de-pending on Fig. 29. Measuring how Fast a Dog Thinks. were required to distinguish between two colors, reactingto blue and not to red. This involved the mental proc-esses of discrimination and choice, in addition to simplereaction. The results are shown in Fig. 30. The figuresat the bottom indicate the ages; those at the left give thenumber of hundredths of a second required for reactionwith discrimination and choice. The topmost line doesnot concern us here. Thinking- Time. 61 REACTION WITH DISCRIMINATION }m CHOICE The time required decreases with age. On the whole,the boys and girls are equally quick, the differences gen-erally being too small to be worth noticing. It might besuggested that, since boys are quicker in simple reaction,they must take a longer time for mere discrimination andchoice in order to give equal totals. The figures seemto indicate that forthe more involvedmental processes thegirls are quicker, butI hesitate to admitsuch a libel on myown sex. Ir
