Map learning and working memory: Multimodal learning strategies

Abstract

The current research investigated whether learning spatial information from a map involves different modalities, which are managed by discrete components in working memory. In four experiments, participants studied a map either while performing a simultaneous interference task (high cognitive load) or without interference (low cognitive load). The modality of interference varied between experiments. Experiment 1 used a tapping task (visuospatial), Experiment 2 a backward counting task (verbal), Experiment 3 an articulatory suppression task (verbal) and Experiment 4 an n-back task (central executive). Spatial recall was assessed in two tests: directional judgements and map drawing. Cognitive load was found to affect spatial recall detrimentally regardless of interference modality. The findings suggest that when learning maps, people use a multimodal learning strategy, utilising resources from all components of working memory.
