Working Memory for Visual and Haptic Targets: A Study Using the Interference Paradigm
We investigated the effect of different types of interference in visual and haptic working memory using a dual-task paradigm. At encoding, 16 young adults performed both, a haptic and a visual primary task followed by the performance of a secondary interference task during a retention interval. The interference task could be a haptic (spatial), visual (spatial), auditory, or control (visual-static) task. The idea was to study the influence of spatial and verbal interference on working memory for spatial targets encoded visually or haptically. The results indicated that the auditory interference task did not deteriorate performance compared to the control condition in which participants performed the visual-static task. The negative effects of spatial interference increased when both the primary and secondary tasks were performed using the same modality. Spatial interference selectively deteriorated both visual and haptic working memory but more strongly the later.
