This study examines when external auditive noise can enhance performance in a dichotic listening and a visuo-spatial working memory task. Noise is typically conceived of as being detrimental for cognitive performance; however, given the mechanism of stochastic resonance (SR), a certain amount of noise can benefit performance. In particular we predict that low performers will be aided by noise whereas high performers decline in performance during the same condition. Data from two experiments will be presented; participants were students at Stockholm University.
