be stored into these different frames, they already seem to develop together in early stages of childhood and appear to be necessarily used in combination in order to solve everyday life tasks. A reference frame can also be used while navigating in space. Here, information is encoded in a way that it effects how we memorize it. This reference frame is used when the observer has to communicate with another person about the objects contained in that space. When navigating a space, an observer can take on either a route perspective or a survey perspective. A route perspective is when the observer navigates in relation to their own body and location, whereas a survey perspective is a bird-eye view of the environment, in order to navigate a space. The usage of a route perspective has no influence on the survey perspective in the activation of the brain, and vice versa. A perspective can be purely route or survey, but often it is a mix of the two that is used in navigation. People can switch between the two seamlessly, and often without noticing. Active navigation appears to have a bigger impact on the establishment of route knowledge, whereas the use of a map seemingly better supports survey knowledge about more large-scaled complex environments. Individual differences There are also individual differences when it comes to experiencing space and the spatial cognition that people have. When looking at individual differences, it appears that most people have a preference for one reference frame with a different use of strategies to represent space. Some people have an inclination towards a route view (also called route strategy), while others have a preference towards a survey view (also called survey or orientation strategy). The people that prefer a route perspective also tend to describe a space more in an egocentric frame of reference. People who have an inclination towards a survey perspective also tend to use an allocentric frame of reference more often. It has been observed that the latter perform better in navigational tasks when they have to learn a route from a map. These individual differences are self-reported with questionnaires. However, the perspective choice is also influenced by characteristics of the environment. When there is a single path in the environment, people usually choose to employ an route perspective. When the environment is open and filled with landmarks, however, people tend to choose a
