Test anxiety is a complex, multidimensional construct composed of cognitive, affective, and behavioral components that have been shown to negatively affect test performance. Furthermore, test anxiety is a pervasive problem in modern society largely related to the evaluative nature of educational programs, therefore meriting study of its nature, causes, effects, and treatment. Aromatherapy is the skilled use of essential oils for physical and emotional well-being and has been used to increase relaxation, attention and memory. This study examined the effects of peppermint and rosemary aromatherapy essential oils and a control scent (apple) on self-reported test anxiety, emotionality and worry subscales of test anxiety, and their effect on test scores of first and second year college science students. Although test anxiety decreased from pre-test to post-test conditions, and test scores increased, no statistically significant changes were noted. No significant association was found between aromatherapy, test anxiety, and test scores. [The dissertation citations contained here are published with the permission of ProQuest LLC.
