Effect of Deprivation of Sight on Subjective Time Sense

¹ Psychiatric Liaison Service, The Johns Hopkins Hospital, Baltimore, Md

The subjective sense of time was studied in three groups of subjects by use of six tests of time estimation. The experimental groups differed in the extent of impairment of vision. The degree of disorientation was related to the extent of reduction of visual sensory input and to the nature of the specific task which was to be performed. Subjects manifested less disorientation on tests which provided cues for orientation and which required active participation in the estimation process. Greater disorientation was manifested on tests which required that the subject use socially determined concepts of time in his response. Disorientation, as defined in this study, was systematic rather than chaotic in character.
