A common goal of human-subject experiments in virtual reality (VR) research is evaluating VR hardware and software for use by the general public. A core principle of human-subject research is that the sample included in a given study should be representative of the target population; otherwise, the conclusions drawn from the findings may be biased and may not generalize to the population of interest. In order to assess whether characteristics of participants in VR research are representative of the general public, we investigated participant demographic characteristics from human-subject experiments in the Proceedings of the IEEE Virtual Reality Conferences from 2015-2019.
Recent meta-analyses reveal age-related declines in short-term memory (STM), working memory, associative memory, prospective memory, face memory, recognition, and recall. The present meta-analyses extend this work beyond predominantly laboratory-based tasks to a naturalistic phenomenon.
