| Popis: | This study examines the potential vulnerability of short-term memory processes to distraction by spatial changes within to-be-ignored bimodal, vibratory, and auditory stimuli. Participants were asked to recall sequences of serially presented dots or digits while being exposed to to-be-ignored stimuli. On unexpected occasions, the bimodal (Experiment 1), vibratory (Experiment 2), or auditory (Experiment 3) stimuli changed their spatial origin from one side of the body (e.g., ear and arm, arm only, ear only) to the other. It was expected that the bimodal stimuli would make the spatial change more salient compared to that of the uni-modal stimuli and that this, in turn, would yield an increase in distraction of serial short-term memory in both the verbal and spatial domains. Performance across three experiments support this assumption as a disruptive effect of the spatial deviant was only observed when presented within the bimodal to-be-ignored sequence (Experiment 1): Uni-modal to-be-ignored sequences, whether vibratory (Experiment 2) or auditory (Experiment 3), had no impact on either verbal or spatial short-term memory. Implications for models of attention capture, short-term memory, and the potential special role attention capturing role of bimodal stimuli is discussed. |
