Abstract： Meta-analysis is a crucial tool for accumulating evidence in basic and applied research. In the open science era, meta-analysis becomes an important way for integrating open data from different sources. Meanwhile, because of the great researchers’ degree introduced by multiple-step and multiple-choices in each step of meta-analysis, the openness and transparency are crucial for reproducing results of meta-analysis. To (1) understand the transparency and openness of meta-analysis reports published in Chinese journals and (2) improve the transparency and openness of future meta-analysis by Chinese researchers, we developed a Chinese version of checklist for meta-analysis, which was based on the Preferred Reporting Items for Systematic Review and Meta-Analysis protocols (PRISMA) and the principle of openness and transparency, and then surveyed the methods and results of 68 meta-analysis papers in mainstream Chinese psychological journals in last five years. Our results revealed that openness and transparency of Chinese meta-analysis reports need to be improved, especially in the following aspects: the date/time and limitation of literature search, the details of screening and data collection, the flow chart of article screening, the details of effect size transformation, and the evaluation of individual research bias. The checklist we present, which lists almost all aspects that an open meta-analysis should include, can be used as a guide for future meta-analysis.

Abstract： Spatial navigation is an essential high-level cognitive function in daily life. However, the involved brain regions such as hippocampus and entorhinal cortex are vulnerable to aging and result in structural atrophy and functional alterations. Using the experimental paradigms like animal experiments, pencil-paper tests, and real-world navigation, early studies explored the behavioral performance of spatial navigation in older adults. By virtue of having similar scenes with realistic environment, compatible with magnetic resonance imaging scanning, and navigator could have interactions with scenes, virtual reality is increasingly applied in the age-related spatial navigation research, revealing the important role of medial temporal cortex such as hippocampus in age-related spatial navigation studies.
