Southard wishes to try to map out these defects in the cerebral structures and thus reason backwards to the somatic inferiority. I confess he lifts me into ideal regions. Such stimuli are enjoyable and provocative of development. DR. TOM A. WILLIAMS, Washington, D. C: I conceive Dr. Southard's purpose somewhat differently from Dr.
Hilaire, and shows what a relatively plastic and sensitive creature the organism is to the surrounding world, the conditions of nutrition and other such influences. There is in this connection a particularly instructive chapter on the physiological and other variations brought about by external influences which act as “stimuli of the nervous system.” The whole theory of Lamarck and St.
The two statements "the hall is full of water" and "the hole is full of water" call for different responses, and a hearing which cannot distinguish between them is inaccurate or vague in this respect. Precision and vagueness in thought, as in perception, depend upon the degree of difference between responses to more or less similar stimuli.
The beautiful woman sees no need for intelligence nor for understanding because she has always been able to outstrip her less attractive competitors in making the best match and securing the rich husbands. And so her neurones rarely "connect," or react, except to stimuli pertaining to things that will enhance her charms and increase her selling price.
All these, and many more could be cited, are instances of the direct influence of environmental factors upon one or more of the endocrines, and so upon the organism as a whole. Indeed, stimuli may be considered to modify an organism only in so far as they modify the glands of internal secretion.
It may also be remarked here that while it is very difficult to believe that spurs were not due in evolution to the mechanical stimulation of striking with the legs in combat, and while specially enlarged feathers are erected in display, we cannot at present attribute the varied and brilliant colour of male birds to the direct influence of external stimuli.
VII. Cure of decreased Exertion. Where the exertion of the sensorial powers is much decreased, as in the cold fits of fever, a gradual accumulation of the spirit of animation takes place; as occurs in all cases where inactivity or torpor of a part of the system exists; this accumulation of sensorial power increases, till stimuli less than natural are sufficient to throw it into action, then the cold fit ceases; and from the action of the natural stimuli a hot one succeeds with increased activity of the whole system.
I went to work very cautiously, moving his limbs about, flicking his face and chest with the corner of a wet towel, tickling the soles of his feet, and otherwise applying stimuli that were strong without being violent.
By such a process we shall finally produce an educated, cultivated man or woman, the crowning glory of education. The measure of our success in this process of education will be the number of reactions we can induce to the right sort of stimuli. In this, we shall have occasion to make many substitutions. The boy who has been reacting to ugliness must be lured away by the substitution of beauty.
The discharge of energy is almost wholly independent of the will and is a self-protective action in the same sense as is the response to pain stimuli. The ear in man and in animals is acutely ticklish, the adequate stimulus being any foreign body, especially a buzzing, insect-like contact.
