Open practice is specific research action that is aimed to promote principles of open science. In psychology, there is a variety of such practices that are integral parts of a series of research activities, including preregistration, registered report, open review, and preprint upload, as well as those that are conducted after completion of the research, e.g., open access and open data. Each open practice is characterised by its specific goals and expected rules, and therefore, has been developed through its respective trajectory. It is desirable to combine a range of open practices within a coherent procedural package in order to advance transparency and accountability of scientific research.
