here between subjective estimates of the reaction time and introspective 
analysis of the reaction consciousness. (11) P. Stroobant, Compt. rend.,

Wundt, P. P., iii., 1903, 436. The essay may be extended beyond the 
reaction experiment to psychophysics at large : cf. H. Leitzmann, P. S., 
V., 1889, 79 ; K. Pearson, Phil. Trans. Roy. Soc. Lond., cxcviii. A, 1902, 
235 ff. (criticise the experimental procedure in this paper). (12) G. O.

§ 38. Compound Reactions : Discrimination, Cognition and Choice. 
—The psychology of the compound reactions discussed in Sec¬ 
tion 26 of the text is, perhaps, in even less satisfactory a state than 
is the psychology of the simple reaction. The first classification 
presented is, of course, purely external. It is useful to the student 
as a bit of mnemotechnics, but it has no psychological signifi¬ 
cance.1 The second classification is psychological : but it is sche¬ 
matic in the extreme, and so far as the assimilative complexes 
‘ discrimination ’ and ‘ cognition ’ are concerned it implies a cer¬ 
tain system of psychology (Wundt, P. P., ii., 1893, 442 ; iii., 1903, 
536). It was put forward by the author in 1898 (Primer, 
260 ff.). 
There can be no doubt that the plan of the compound reaction 
may be widely varied beyond the limits of this second classifica¬ 
tion. There can be little doubt, either, that the classification 
groups together problems of very various degrees of psychologi¬ 
cal complexity, problems which are therefore, in reality, differ¬ 
ent problems. Nevertheless, Wundt has made this field of experi¬ 
mental work so peculiarly his own that it seems unwise, on the 
basis of the material at hand and in a work like the present, to 
undertake any more detailed analysis. 
1 A somewhat similar classification, in which, however, psychological factors 
play a part, was proposed by Jastrow, Time Relations, 1890, 27. The author’s 
table was made out independently of Jastrow’s work.
