Instead, they indicate differential effects on perception and cognition depending on a variety of factors such as task demands and timing of white noise presentation.. During working memory, acoustic white noise impaired accuracy when presented during the maintenance period (Experiments 1–3). Hypothesizing an involvement of the mesolimbic dopamine system and its functional interactions with cortical areas, the current study aimed to demonstrate a facilitation of dopamine-dependent attentional and mnemonic functions by externally applying white noise in five behavioral experiments including a total sample of 167 healthy human subjects..

Yet, diversity of conceptions and levels of observation render the underlying mechanisms difficult to grasp and demand cautious interpretation (;; ). In a modified Posner task (Experiment 5), the benefit due to white noise in attentional orienting correlated weakly with reward dependence, a personality trait that has been associated with the dopaminergic system.. During working memory, acoustic white noise impaired accuracy when presented during the maintenance period (Experiments 1-3).. Beneficial effects of noise have intensively been studied for sensory perception within the visual (;;; ), somatosensory (;;; ), and auditory domain (; ), across different modalities (;; ), as well as for sensorimotor processing (;;;; )..

Introduction There is a growing body of research dealing with the sources and impact of noise in neural systems.. In a modified Posner task (Experiment 5), the benefit due to white noise in attentional orienting correlated weakly with reward dependence, a personality trait that has been associated with the dopaminergic system.. Adding noise to a signal of interest can thus improve information processing – a mechanism that has been labeled stochastic resonance, or stochastic facilitation in a broader sense (;; ).. These results suggest that white noise has no general effect on cognitive functions.. Beneficial effects of noise on higher cognition have recently attracted attention.. EuroPlus REWARD English For more than three decades and in over 20 countries worldwide, the Thomson Reuters Lipper Fund Awards have honored funds and fund management firms that have excelled.. Noise is an inherent feature of neural processing that affects perception, decision making, and motor function () and is not necessarily detrimental but can also have constructive roles (), for instance by improving reliability of spike firing in single neurons or boosting synchrony across neural populations ().. These results suggest that white noise has no general effect on cognitive functions. e828bfe731
