Spatial navigation is a complex skill that relies on many aspects of cognition. The followingstudies aimed to clarify the role of working memory in spatial navigation, and particularly, thepotentially differential contributions of verbal and visuospatial working memory. Study 1leveraged individual differences to understand how working memory differs among types ofnavigators and the predictiveness of verbal and visuospatial working memory. Participantscompleted multiple measures of verbal and visuospatial working memory and spatial navigation.Study 2 further evaluated the impact of a working memory load on spatial navigation performance.Using a dual-task paradigm, the decrement (or not) of performance on spatial navigation can becompared between control, verbal, and visuospatial conditions. Study 1 showed that individualdifferences in visuospatial working memory are more predictive than verbal working memory.However, Study 2 provides evidence for the necessary role for both verbal and visuospatialworking memory.
