Hence it appears, that our perceptions themselves are copies, that is, imitations of some properties of external matter; and the propensity to imitation is thus interwoven with our existence, as it is produced by the stimuli of external bodies, and is afterwards repeated by our volitions and sensations, and thus constitutes all the operations of our minds.

Considered in themselves, apart from the traditions of formality, these are quite good play material or stimuli, and Froebel meant the time to come "when we shall speak of the doll and the hobby horse as the first plays of the awakening life of the girl and the boy," but he died before he had done so.

There is no occasion to describe the rows of ditches, dry and wet; the staked pitfalls; the cervi, pronged instruments like the branching horns of a stag; the stimuli, barbed spikes treacherously concealed to impale the unwary and hold him fast when caught, with which the ground was sown in irregular rows; the vallus and the lorica, and all the varied contrivances of Roman engineering genius.

Among these needs are not only such as we usually call necessities the stimuli of individual desire and volition but also those connected with individual views and convictions; or to use a term expressing less decision leanings of opinion, supposing the impulses of reflection, understanding, and reason, to have been awakened.

By increasing the pressure on the means of subsistence, a larger population again augments these results; seeing that each person is forced more and more to confine himself to that which he can do best, and by which he can gain most. Presently, under these same stimuli, new occupations arise.

If the child has no resources in solitude, can not think without the visual provocation, is losing subjective life, enthusiasm for public, social, ethical questions, is crippled for intellectual pursuits, cares only in a languid way for literary prose and poetry, responds only to sensuous stimuli and events at short range, and is indifferent to all wide relations and moral responsibility, cares only for commercial self-interest, the tactics of field sport, laboratory occupations and things which call be illustrated from a pedagogic museum, then the school is dwarfing, in dawning maturity, the higher powers that belong to this stage of development and is responsible for mental arrest.

Moreover, "the hesitation of stammerers on certain words or letters is due to disturbing complexes. The stammering does not cause the inhibition, it is the inhibition which is at the bottom of the stammering." "Two types of stimuli lead to stammering, either internal conflicts, or external instigators which throw these conflicts into activity. "Thus," says Dr.

They are acted upon by external stimuli, while their impulses in turn act on the neurons in the spinal cord. This, the intermediate division, may be composed of mon-axonic neurons, or it may consist of branches from the afferent neurons. From the central nervous system to the muscles. This, the efferent division, is made up of mon-axonic neurons.

While choice, when two competing stimuli awake competing mechanisms, may be non-cerebral in its nature, largely speaking it is a function of the cerebrum, of the intelligence. To choose is a constant work of the intelligence, just as to doubt is an unavailing effort to find a choice. Choice blocked is doubt, one of the unhappiest of mental states.

We may suppose that when all external stimuli are withdrawn, or the brain soothed by monotony of gentle repetition, and when the body is placed at rest, and the viscera are normal and give rise to no disturbing sensations, consciousness is then suspended, and natural sleep ensues.
