The study of a case of voyeuristic perversion and of some previously published cases of simple scopophilia suggests that fear of object loss early in life may be an important factor predisposing one to a propensity for voyeurism. The increased need to maintain visual contact with the object and to incorporate it visually leads to a hypercathexis of the visual function which is at the base of voyeurism. This need later becomes sexualized, while still retaining its pregenital connotations. Although object loss was apparently significant in the case of the patient described in this paper, it is not necessarily a factor in all cases of perverse voyeurism and, when present, may be considered as only one element in its pathogenesis.
