M. Perez (_op. cit._, p. 65) calls in the evolution hypothesis here, suggesting that the child, unlike the young animal, is so organised as to be more on the alert for dangers which are near at hand (auditory impressions) than for those at a distance (visual impressions). I confess, however, that I find this ingenious writer not quite convincing here. ----- At the outset it is well, as in the case of the ear-fears, to keep before us the distinction between a mere dislike to a sensation and a true reaction of fear. We shall find that children’s quasi-æsthetic dislikes to certain colours may readily simulate the appearance of fears. Among the earliest manifestations of fear excited by visual impressions we have those called forth by the presentation of something new and strange, especially when it involves a rupture of customary arrangements. Although children love and delight in what is new, their disposition to fear is apt to give to new and strange objects a disquieting, if not distinctly alarming character. This apprehension shows itself as soon as a child has begun to be used or accustomed to a particular state of things. Among the more disconcerting effects of a rude departure from the customary, we have that of change of place. At first the infant betrays no sign of disturbance on being carried into a new room. But when once it has grown accustomed to a certain room it will feel a new one to be strange, and eye its features with a perceptibly anxious look. This sense of strangeness in place sometimes appears very early. The little girl M., on being taken at the age of four months into a new nursery, “looked all round and then burst out crying”. This feeling of uneasiness may linger late. A boy retained up to the age of three years eight months the fear of being left alone in strange hotels or lodgings. Yet entrance on a new abode does not by any means always excite this reaction. A child may have his curiosity excited, or may be amused by the odd look of things. Thus one boy on being taken at the age of fifteen months to a fresh house and given a small plain room looked round and laughed at the odd carpet. Children even of the same age appear in such circumstances to vary greatly with respect to the relative strength of the impulses of fear and curiosity.
