Parallel Experiments: From The Human Participated to A Virtual-Real Hybrid Paradigm

Experiment is one of the necessary conditions for scientific progress. For cognitive science, neuroscience, biomedical science and other human-related disciplines, experiments involving human subjects can confirm or disprove scientific hypotheses in a controlled and systematic manner, while establishing causal relationships between studied variables. These experiments also provide both qualitative and quantitative analysis capable of statistically identifying significant patterns. Thus, solid experiments directly support testable and replicable scientific conclusions. However, limited by the budget as well as the available candidate group, current experiment design selects random subjective in an arbitrary scale, bringing a question that how they can stand for the whole studied population.
