HISTORIES OF SEXUAL DEVELOPMENT.

    HISTORY I.—­The following narrative has been written by a
    university man trained in psychology:—­

So far as I have been able to learn, none of my ancestors for at least three generations have suffered from any nervous or mental disease; and of those more remote I can learn nothing at all.  It appears probable, then, that any peculiarities of my own sexual development must be explained by reference to the somewhat peculiar environment.

I was the first child and was, naturally, somewhat spoiled—­a process which tended to increase my natural tendency to sentimentality.  On the other hand, I was shy and undemonstrative with all except my nearest relatives, and with them as well after my seventh or eighth year.  And here it may be well to describe my “mental type,” as this is probably the most important factor in determining the direction of one’s mental development.  Of mental types the “visual” is, of course, by far the most common, but in my own case visual imagery was never strong or vivid, and has constantly grown weaker.  The dominant part has been played by tactual, muscular and organic sensations, placing me as one of the “tactual motor” type, with strong “verbal motor” and “organic” tendencies.  In reading a novel I seldom have a mental picture of the character or situation, but easily imagine the sensations (except the visual) and feel something of the emotions described.  When telling of any event I have a strong impulse to make the movements described and to gesticulate.  I remember events in terms of movements and the words to be used in giving an account of them; and in thinking of any subject I can feel the movements of the larynx and, in a less degree, of the lips and tongue that would be involved in putting my thoughts into words.  I am easily moved to emotion, even to sentimentality, but am seldom if ever deeply affected and am so averse to any display of my feelings that I have the reputation among my acquaintances of being cold, unfeeling and unemotional.  I am naturally quiet and bashful to a degree, which has rendered all forms of social intercourse painful through much of my life, and this in spite
