Web-based research methodology has evolved since the development of the world wide web in the 1990s and has proliferated and diversified with layers upon layers of new major developments in internet technology and life generally (e.g., search engines, social media, smartphones, Open Science). This volume presents a selection of state-of-the-art contributions on web-based research in psychology. Expert authors explore research methodology, including new methods made possible through the web or research that cannot be done without the web. In addition, research ethics, which have special characteristics in the online research environment, are addressed to varying degrees, including deception and inclusivity. Further topics presented range from how web-based research can advance our knowledge on perception to the adoption of Open Science (including sharing data, materials, and preregistrations), as well as how behavior is observed in web-based research. This collection of contributions is a showcase of the creativity of researchers to find nifty new ways to harness the web to advance psychological research.
