In the tripartite model of working memory (WM) it is postulated that a unique part system—the visuo-spatial sketchpad (VSSP)—processes non-verbal content. Due to behavioral and neurophysiological findings, the VSSP was later subdivided into visual object and visual spatial processing, the former representing objects’ appearance and the latter spatial(More)
A series of experiments compared short-term memory for object locations in the auditory and visual modalities. The stimulus materials consisted of sounds and pictures presented at different locations in space. Items were presented in pure- or mixed-modality lists of increasing length. At test, participants responded to renewed presentation of the objects by(More)
We compared spatial short-term memory for visual and auditory stimuli in an event-related slow potentials study. Subjects encoded object locations of either four or six sequentially presented auditory or visual stimuli and maintained them during a retention period of 6 s. Slow potentials recorded during encoding were modulated by the modality of the(More)
If configurations of objects are presented in a S1-S2 matching task for the identity of objects a spatial mismatch effect occurs. Changing the (irrelevant) spatial layout lengthens response times. We investigated what causes this effect. We observed a reliable mismatch effect that was not influenced by a secondary task during maintenance. Neither(More)
Previous studies conducted in our lab provided evidence that object locations of sounds and pictures are maintained by a common mechanism. This suggests that working memory for spatial locations is not separated according to input modality. Additionally, it is known that in visual short-term memory, location and object information are maintained by(More)
