(8) Suppose that you perform a selective action; the action issues from a conflict of determining tendencies; you ‘decide’ among various possibilities of action. Does the decision always take place in the same way, or can you distinguish ‘types’ of decision?—Do not hurry to answer the question; keep it by you, and answer it in the light of experience. (9) We saw that the motor reaction (which has its counterpart in everyday life) is a telescoped impulsive action. Can you mention any other kinds of action (also occurring in everyday life) which do not find their precise place under the headings of the chapter? (10) What kinds of action are involved in the product of constructive imagination? (11) (_a_) What is the chief psychological difference between hesitation and deliberation? (_b_) Give, from your own experience, a detailed analysis of some desire. (12) It is very important that you should become acquainted with the reaction experiment, and should analyse a number of reactions. Many instrumental outfits are on the market; one of the simplest is President E. C. Sanford’s vernier chronoscope (C. H. Stoelting Co.). When you have familiarised yourself with the experiment, try to plan an experimental study of selective and volitional actions. References W. James, Principles of Psychology, ii., 1890, ch. xxvi.; W.
