Does active learning benefit spatial memory during navigation with restricted peripheral field?

Spatial learning of real-world environments is impaired with severely restricted peripheral field of view (FOV). In prior research, the effects of restricted FOV on spatial learning have been studied using passive learning paradigms – learners walk along pre-defined paths and are told the location of targets to be remembered. Our research has shown that mobility demands and environmental complexity may contribute to impaired spatial learning with restricted FOV through attentional mechanisms. Here, we examine the role of active navigation, both in locomotion and in target search. First, we compared effects of active versus passive locomotion (walking with a physical guide versus being pushed in a wheelchair) on a task of pointing to remembered targets in participants with simulated 10° FOV. We found similar performance between active and passive locomotion conditions in both simpler (Experiment 1) and more complex (Experiment 2) spatial learning tasks. Experiment 3 required active search for named targets to remember while navigating, using both a mild and a severe FOV restriction. We observed no difference in pointing accuracy between the two FOV restrictions but an increase in attentional demands with severely restricted FOV. Experiment 4 compared active and passive search with severe FOV restriction, within subjects. We found no difference in pointing accuracy, but observed an increase in cognitive load in active versus passive search. Taken together, in the context of navigating with restricted FOV, neither locomotion method nor level of active search affected spatial learning. However, the greater cognitive demands could have counteracted the potential advantage of the active learning conditions.

     

Children’s Understanding and Use of Four Dimensions of Social Status

ABSTRACT

Beginning early in life, children are exposed to people who differ in social status. In five studies, we investigate whether 3- to 6-year-old children recognize different dimensions of status (i.e., wealth, physical dominance, decision-making power, and prestige) and use these dimensions to inform their social judgments (preferences and resource allocation). Across studies, we found that by age 3, children identify high-status people as in-charge. Further, while 3-6-year-olds favor higher status individuals over lower status individuals on a preference measure, 5-6-year-olds allocate a resource to a lower status individual over a higher status individual and 3-4-year-olds are at chance in their allocation. We observed minimal differences across dimensions of status in these studies. Taken together, across five pre-registered studies, we demonstrated that children identify and use social status distinctions to inform their social judgments across a variety of different dimensions.
