Visual short-term memory have been shown to be selectively impaired in patients with Alzheimer’s disease; furthermore, it seems as there is something intrinsic about short-term memory deficits in Alzheimer’s disease since this impairment is not found in other forms of dementia or depression and have been shown to be sensitive for identifying who is going to develop the disease. Moreover, although overall memory performance for single feature visual stimuli and bound features is poorer in older adults compared to young adults, visual binding capacities are preserved in old age. Thus, deficits in short-term memory binding provides a specific measurement for detecting Alzheimer’s disease at an early stage. However, there has been no studies on this in relation to other sensory modalities, and therefore, the primary aim of the present study was to investigate whether visual and auditory short-term memory binding operates in the system. The results of the present study suggest that there is a cost in memory for binding features for auditory and visual stimuli, moreover, there is no shared function between auditory and visual short-term memory binding. The results also indicate that musical training influence auditory binding.
