Successful navigation: the influence of task goals and working memory

There is still a need to analyze the factors that enhance navigation accuracy. This study aims to examine how success in environment learning relates to task goals and WM. A total of 90 undergraduates (46 females) learned a route from a virtual navigation experience after being given a goal that involved tracing the route (a route-based goal) or finding a shortcut (a survey-based goal). The two groups thus formed were each divided into three subgroups according to the dual-task paradigm: one only navigated (control condition); the other two did so while simultaneously performing a visuo-spatial or verbal secondary task. Afterwards, participants traced the previously seen route and found a shortcut. Several visuo-spatial and verbal WM tasks were also administered. The results showed that participants given a route-based goal performed better in the route-tracing task; and those given a survey-based goal were better at finding shortcuts. An influence of WM was also shown: higher WM (visuo-spatial and verbal) ability significantly reduced the number of route-tracing errors made while performing a secondary visuo-spatial task, regardless of the goal, whereas no such effects emerged for shortcut finding. These results offer new insight on how task goals and WM support successful navigation.

Automated summary

This study explores the relationship between successful navigation, task goals, and working memory. Results indicated that participants with route-based goals performed better in route-tracing tasks, while those with survey-based goals were better at finding shortcuts. Higher working memory ability (both visuo-spatial and verbal) helped reduce errors in route-tracing tasks during secondary visuo-spatial tasks.
