title: Relationship between spatial density and sensory overload, personal space, and systolic and diastolic blood pressure.
abstract: Selected effects of high spatial density were investigated with 26 boys, serving as their own controls and undergoing alternate confinements in high and relatively low spatial density. Measured effects were changes in minimal aversion threshold values of white sound, projective measures of desire to alter room size, and systolic and diastolic blood pressure. High spatial density increased systolic and diastolic blood pressure and projective measures of desire to alter room size but did not affect minimal aversion threshold values. Semi-projective measures of personal space requirements were obtained prior to experimental trials. Analysis showed a significant interaction of minimal aversion threshold values with requirements for personal space; the minimal aversion threshold values of subjects requiring large personal space tended to decrease following confinement under high spatial density. The interaction of personal space with projected measures of desire to alter room size was not significant. High spatial density may, then, exert adverse effects on blood pressure and may induce sensory overload conditions in individuals requiring large personal space.
