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.     

What happened in kindergarten? Mother-child conversations about life story chapters

ABSTRACT

Research indicates that adults form life story chapters, representations of extended time periods that include people, places and activities. Life chapter memories are distinct from episodic memories and have implications for behaviour, self and mental health, yet little is known about their development during childhood. Two exploratory studies examined parent–child conversations about life chapters. In Study 1, mothers recorded naturalistic conversations with their 5–6 year old children about two chapters in the child’s life. In Study 2, mothers recorded conversations with their 6–7 year old children about a particular life chapter—the child’s kindergarten year—and also about a specific episode of their choice. The results indicated that young children are able to recall and discuss information about life chapters and that parents actively scaffold children’s discussion of general information in chapters as well as specific events. Mothers’ conversational style when discussing chapters (e.g., elaborativeness) predicted children’s memory contributions, and was also positively correlated with their style when discussing specific events. The results suggest new avenues for research on the ontogeny of life chapters, the factors that shape them, and their role in development.     

The detrimental effect of academic procrastination on subsequent grades: the mediating role of coping over and above past achievement and working memory capacity

Background: Academic procrastination is common among university students and its effect on their achievement is worrisome. Although procrastination is often depicted as self-regulation failure, research still needs to examine the self-regulatory mechanisms involved in the relationship between procrastination and achievement.

Objectives: In this prospective study, we sought to (a) unravel the unique effect of academic procrastination on university grades, (b) examine the mediating role of task-oriented and disengagement-oriented coping as a self-regulatory pathway toward achievement, (c) control for the potential confounding influence of past achievement and working memory capacity.

Methods: A sample of 258 university students completed self-report measures of academic procrastination and coping, and performed tests of working memory. Their semester grade point average was collected at the end of the semester.

Results: Results of structural equation modeling showed that academic procrastination negatively predicted subsequent academic achievement, even after controlling for high school achievement and working memory capacity. Furthermore, indirect effects revealed that task- and disengagement-oriented coping explained 70% of the total effect.

Conclusion: These findings outline that the effect of academic procrastination cannot be reduced to a history of academic difficulties or limited cognitive ability and that coping plays an important role in the procrastination – achievement relationship.
