KembaraXtra-Psychology - Artifacts (artefacts)
Artifacts are items deliberately made by humans, including practical objects such as tools as well as creative products such as artworks. In research, an artifact also means something recorded or noticed during an empirical study that does not occur naturally in the situation being studied, but instead appears as an unintended side-effect or by-product of the methods, instruments, or procedures used. The spelling artifact is especially common in US usage. The adjectives artefactual and artifactual refer to something that is an artifact in either sense. The term comes from Latin roots meaning “made by skill or art.”
