The influence of angle, approach, and sex of subject on the personal space distance needs of the elderly person was examined. Subjects were 20 females and 20 males, age 65 or older, living in the same retirement housing unit. The behavioral measurement technique showed acceptable test-retest reliability. A significant three-way interaction effect was identified. The main effects of angle and approach were significant; a main effect by sex of the subject was not supported. Elderly subjects allowed a stimulus-individual (identified as a nurse) to approach closer than they approached the same stimulus-individual, suggesting that personal space is a factor to be considered by those giving care to or working with the elderly. Personal space is a complex phenomenon needing further study, especially in relation to the elderly. (Author)
