Effects of Multi-sensory Stimulation on the Cognitive Characteristics of Nursery Facilities

In this study, EEG(electroencephalogram) and Vibra images were compared and analyzed in an environmental test room. The images were obtained by providing multi-sensory stimulation (four types of sound fluctuations, three sound volume levels, three color/temperature values, and three fragrances). The aim was to determine the optimal multi-sensory stimulation and to increase the cognitive characteristics of the nursery facilities. The environmental test room specifications were as follows: temperature, 25 °C; relative humidity, 50 RH%; air current speed, 0.02 m/s; and illumination, 1000 lux. At a sound fluctuation of a = 2.1968 (music) and color temperature of 2,700 K, for lavender scent, the relative Mβ and SMR/θ increased, and the Vibra images of tension and anxiety decreased. Therefore, multi-sensory stimulation of sound fluctuation a = 2.1968, sound volume 30 dB, color/temperature 2,700 K, and lavender scent led to an increase in the cognitive characteristics.
