Psychophysiological responses to geranium visual stimuli were analyzed on female college students with low attentiveness. Alpha and fast-beta brain wave activities, electrodermal activities, and skin temperature were measured continuously during a 5-min baseline, a 10-min induced stressor, and a 5-min treatment. Each of 75 female college students viewed a film of a stressful human situation—an induced stressor, then was exposed to a randomly assigned treatment: red-flowering geraniums, nonflowering geraniums, or no plants. Based on responses to the induced stressor, students were placed into non-, mild-, and high-induced stress groups. Regression models of psychophysiological responses to each treatment were developed for over-all stress levels. Non-induced stress female students exposed to red-flowering geraniums in contrast to nonflowering geraniums and no-plants showed greater fast-beta brain wave activity. Greater fast-beta of non-induced stress female students exposed red-flowering geraniums was associated with increased positive attention and not because of increased stressful tension. This conclusion was supported by more positive emotional states self-reported using the Zuckerman Inventory of Personal Reactions. Conclusive findings from over-all stress levels suggest that benefits of viewing red-flowering geraniums occur to both nonstress and high stress female college students; red-flowering geraniums improve positive attention of female students with no stress (low attentiveness) and enhance stress recovery of female students with high stress (tension).
