Lighting to Make You Feel Better: Improving the Mood of Elderly People with Affective Ambiences.

Kuijsters A, Redi J, de Ruyter B, Heynderickx I - PLoS ONE (2015)

Bottom Line: We hypothesized that ambiences with a clearly recognizable, positive affective meaning could be used to effectively mitigate negative mood in elderly.In line with our hypothesis we found that the activating ambience was physiologically more arousing than the neutral ambience.The cozy ambience was more effective in calming anxious elderly than the neutral ambience, as reflected by both the self-reported and physiological measurements.

ABSTRACT
Current lighting technologies extend the options for changing the appearance of rooms and closed spaces, as such creating ambiences with an affective meaning. Using intelligence, these ambiences may instantly be adapted to the needs of the room's occupant(s), possibly improving their well-being. We hypothesized that ambiences with a clearly recognizable, positive affective meaning could be used to effectively mitigate negative mood in elderly. After inducing a sad mood with a short movie one group of elderly was immersed in a positive high arousing (i.e., activating) ambience, and another group in a neutral ambience. Similarly, after inducing anxiety with a short movie one group of elderly was immersed in a pleasant low arousing (i.e., cozy) ambience, and another group in a neutral ambience. We monitored the evolution of the mood of the four groups of elderly over a period of ten minutes after the mood induction, with both self-reported mood measurements (every 2 minutes) and constant measurements of the skin conductance response (SCR) and electrocardiography (ECG). In line with our hypothesis we found that the activating ambience was physiologically more arousing than the neutral ambience. The cozy ambience was more effective in calming anxious elderly than the neutral ambience, as reflected by both the self-reported and physiological measurements.

Mentions: Fig 4 presents the subjective pleasure (left) and arousal (right) scores before and after the mood induction for both the sad and anxious movie. For the sad movie we found that the pleasure ratings were significantly reduced after the mood induction (F(1, 34) = 120.92, p < .001, η2 = .78) as intended. Also the effect of gender reached significance for pleasure (F(1, 34) = 6.33, p = .017, η2 = .16); further analyses revealed that males scored higher on pleasure at baseline (M = 7.11) and after the sad movie (M = 4.21) than females (at baseline M = 6.26, and after the sad movie M = 2.95). In contrast with our expectations the SAM arousal ratings were significantly increased by the mood induction (F(1, 34) = 37.27, p < .001, η2 = .52). We found also here a gender effect (F(1, 34) = 8.27, p = .007, η2 = .20). Further analysis revealed that females scored higher on arousal at baseline (M = 3.21) and after the sad movie (M = 5.53) than males (at baseline M = 2.11, and after the sad movie M = 4.32). For the physiological measures a significant effect of the sad mood induction on SCR and HR was found. In line with the SAM arousal ratings, also the SCR significantly increased during the mood induction (F(1, 32) = 4.44, p = .043, η2 = .12) from M = 4.09 at baseline to M = 4.34 during mood induction. Also the HR increased significantly (F(1, 31) = 4.89, p = .034, η2 = .14) from M = 66.58 at baseline to M = 67.40 during mood induction. Furthermore a gender x ambience group interaction effect was found on HR (F(1, 31) = 9.44, p = .004, η2 = .23); further analysis revealed that the females in the neutral ambience group had a higher HR (M = 74.1) than the male participants (M = 60.6), whereas a reversed effect was found for the activating ambience group (females M = 63.2, and males M = 70.9).
