Olfactory or auditory stimulation and their hedonic valúes differentially modulate visual working memory

Working memory (WM) designates the retention of objects or events in conscious awareness when these are not present in the environment. Many studies have focused on the interference properties of distracter stimuli in working memory, but these studies have mainly examined the influence of the intens...
