It is possible to present such relational problems by means of relatively simple reaction-mechanisms.

The procedure was as previously described in that the experimenter raised the entrance doors of a certain group of boxes, admitted the animal to the reaction-chamber, punished incorrect choices by confining the animal for thirty seconds, and rewarded correct choices by raising the exit door and thus permitting escape and the obtaining of food.

ALLPORT, FLOYD N. The A-S reaction study.

Another boat, the Albert, was built at Stettin, after the same type and at about the same epoch; and the question was considered of placing a reaction propeller upon the Great Eastern.

Thus, for example, with the entrance and exit doors of box 7 raised, the monkey was allowed to pass into the reaction-compartment E and thence through box 7 to the food cup.

The reaction potential of the ante-pituitary, that is its inherent, latent ability to supply a maximum of its endocrine for the nerve cells of the frontal lobes, is the best-known chemical determinant of intellectual genius.

HAMMETT, LOUIS P. Physical organic chemistry; reaction rates, equilibria & mechanisms.

MAN'S The kinds of personality described, as prototypes and variants and the fundamental facts supporting the view that they are the reaction types of the human beings we meet in everyday life, represent simply a beginning of the work to be done.

Grim's authority is always at its height on the outbound trail, for then everybody knows that success, and even safety, depends on his swift thinking; on the way home afterward reaction sets in sometimes, because Arabs are made light-headed by success, and it isn't a simple matter to discipline free men when you have no obvious hold over them.

The real tragedy of Russia is that neither the party of reform nor the party of reaction shares, or even understands, the outlook and ideals of the people.

They consist of a series of precisely similar reaction-devices, any one or all of which may be used in connection with a given observation.

He needs an excess of sleep, sleeps heavily, needs sleep during the day, when awakened in the morning still feels tired, and rather dull and restless, dresses slowly, has to be coaxed or forced to dress, gets to school late nearly every morning, does badly at the school, reaction time, learning time and remembering time being prolonged as compared with the average, and is lazy at home lessons.

The delayed reaction method of Hunter, the quadruple-choice method of Hamilton, and my multiple-choice method offer new and promising approaches to forms of activity which thus far have been only superficially observed.
