Wayfinding requires monitoring movements in the environment, in addition to identifying stable landmarks. The current study investigated how moving entities impact wayfinding. Experiment 1 evaluated the effects of moving entities that were presented during the acquisition but not during retrieval. Experiment 2 examined the effect of presenting moving entities during retrieval that were not presented during initial learning. Experiments 3 and 4 examined whether movement per se or attention directed to movement accounted for the effects of moving entities. We found that moving entities disrupted wayfinding more if they were presented during the acquisition stage and removed during retrieval. No …

Objective: Learning and memory impairments are common in multiple sclerosis (MS) and may be related to difficulty acquiring (encoding or consolidating) new information. We evaluate the role of retroactive interference and investigate whether minimizing interference immediately following encoding (early during consolidation) will improve MS participants' ability to remember new verbal information. Additionally, we investigate processing speed differences between memory-impaired and unimpaired participants and present an exploratory analysis of how the dual-components of working memory (capacity vs. processing) relate to memory impairment. Method: MS memory-unimpaired (N = 12) and MS memory-impaired participants (N = 12) were compared to healthy controls (N …
