Cardiovascular effects of traffic noise: the role of negative self-statements
Published online by Cambridge University Press: 09 July 2009
Synopsis
This study assesses cardiovascular and subjective effects of traffic noise and the mediator role that negative self-statements play. Eighty-four female students underwent a Physiological Reaction Test to two 15 min presentations of high intensity traffic noise (85–95 db) under two noise conditions, with and without negative self-statements. Half of the subjects were given specific instructions to increase the credibility of the self-statements. Dependent variables were heart rate (HR), blood volume pulse amplitude from both temporal arteries and subjective tension. Traffic noise provoked subjective tension and cardiovascular responses that did not habituate either within or between noise presentations. Negative self-statements had the greatest effect on HR. In fact, this response habituated to a second noise presented only when this condition was without negative self-statements. Instructions increased the effect of the self-statements only on the left temporal artery and also increased subjective tension. The implications of this physiological reactivity in psychosomatic problems and the importance of negative self-statements are discussed.
