The study of navigation is informed by ethological data from many species, laboratory investigation at behavioural and neurobiological levels, and computational modelling. However, the data are often species-specific, making it challenging to develop general models of how biology supports behaviour. Wiener et al. outlined a framework for organizing the results across taxa, called the 'navigation toolbox' (Wiener et al. In Animal thinking: contemporary issues in comparative cognition (eds R Menzel, J Fischer), pp. 51–76). This framework proposes that spatial cognition is a hierarchical process in which sensory inputs at the lowest level are successively combined into ever-more complex representations, culminating in a metric or quasi-metric internal model of the world (cognitive map). Some animals, notably humans, also use symbolic representations to produce an external representation, such as a verbal description, signpost or map that allows communication of spatial information or instructions between individuals. Recently, new discoveries have extended our understanding of how spatial representations are constructed, highlighting that the hierarchical relationships are bidirectional, with higher levels feeding back to influence lower levels. In the light of these new developments, we revisit the navigation toolbox, elaborate it and incorporate new findings. The toolbox provides a common framework within which the results from different taxa can be described and compared, yielding a more detailed, mechanistic and generalized understanding of navigation.

As babies rapidly acquire motor skills that give them increasingly independent and wide-ranging access to the environment over the first two years of human life, they decrease their reliance on habit systems for spatial localization, switching to their emerging inertial navigation system and to allocentric frameworks. Initial place learning is evident towards the end of the period. From 3 to 10 years, children calibrate their ability to encode various sources of spatial information (inertial information, geometric cues, beacons, proximal landmarks and distal landmarks) and begin to combine cues, both within and across systems. Geometric cues are important, but do not constitute an innate and encapsulated module. In addition, from 3 to 10 years, children build the capacity to think about frames of reference different from their current one (i.e. to perform perspective taking). By around 12 years, we see adult-level performance and adult patterns of individual differences on cognitive mapping tasks requiring the integration of vista views of space into environmental space. These lines of development are continuous rather than stage-like. Spatial development builds on important beginnings in the neural systems of newborns, but changes in experience-expectant ways with motor development, action in the world and success-failure feedback. Human systems for integrating and manipulating spatial information also benefit from symbolic capacities and technological inventions. [ABSTRACT FROM AUTHOR]

Research on the existence of cognitive maps and on the cognitive processes that support effective navigation has often focused on functioning across individuals. However, there are pronounced individual differences in navigation proficiency, which need to be explained and which can illuminate our understanding of cognitive maps and effective navigation. Using a virtual environment involving 2 routes (Virtual Silcton, a desktop virtual environment; Weisberg, Schinazi, Newcombe, Shipley, & Epstein, 2014), we divided people into 3 groups based on their within-route and between-route pointing accuracy: integrators, non-integrators, and imprecise navigators. In Study 1, we found that imprecise navigators have lower spatial and verbal working memory, which may limit their ability to build accurate within-route representations. We also found that integrators maintain excellent memories of buildings as categorized by route membership, possibly supporting the idea of hierarchical representations of the environment. In Study 2, we assessed preferences regarding place and route learning using a virtual version of the rodent T-maze (Marchette, Bakker, & Shelton, 2011). Integrators found more goals overall, and although they did not have an overall preference for a place-based strategy, integrators who did choose a place-based strategy found more goals. The opposite was true for imprecise navigators. In Study 3, we added a monetary incentive for accuracy to evaluate whether increased motivation leads to fewer participants classified as imprecise, but found no significant change in the distribution of performance. These data have theoretical implications for the cognitive map hypothesis, and practical implications for improving navigational functioning. A one-size-fits-all approach may fit none.

• Individual differences in navigation stabilize at around 12 years of age. • Within-route judgements of direction stabilize before between-route judgements. • Before age 12, within-route judgements predict change in between-route judgments. • Perspective-taking and mental rotation do not predict children's navigation overtime. • Parent's small-scale spatial skills are not associated with children's navigation. Cross-sectional studies have suggested that the ability to form cognitive maps increases throughout childhood and reaches adult levels during early adolescence. However, adults show large individual differences in their ability to relate local routes to form a global map. Children also vary, but when does variation stabilize? We asked participants from a previously published cross-sectional study [ Journal of Experimental Child Psychology (2018), Vol. 170, pp. 86–106] to return for a second session of testing 3 years later to examine whether longitudinal stability is more evident at older ages. The subsample of 50 of the original 105 participants available for retesting did not differ from the original sample on male–female ratio or Session 1 task performance. We reassessed performance on the Virtual Silcton navigation paradigm, the Spatial Orientation Test (SOT), and the Mental Rotation Test (MRT) and added parents' scores on the SOT and MRT at Timepoint 2. Our initial analyses of normative development aligned with prior cross-sectional findings; overall navigation performance reached adult levels of proficiency around 12 years of age. In addition, variation in route integration abilities, as measured by between-route pointing, stabilized around 12 years of age; that is, longitudinal stability was higher in the older cohort than in the younger cohort. The same pattern appeared for the MRT. [ABSTRACT FROM AUTHOR]
