Lisäkokeita

Lisäkokeita is a Finnish term used in scientific writing to refer to supplementary or additional experiments conducted after an initial study to verify findings, extend the investigation, or test robustness under different conditions. The word combines lisä (additional) and kokeita (experiments).

The term is commonly used across fields such as medicine, psychology, biology, and physics, where researchers perform follow-up studies, replication attempts, or parameter sweeps. Lisäkokeita can aim to confirm results, test generalizability to other populations or settings, calibrate instruments, or examine sensitivity to methodological choices. They can be planned as a separate project or as part of a staged program of research.

Design and reporting practices for lisäkokeita align with broader research norms. They should be preregistered when possible, employ adequate sample sizes, and report methods and results transparently to reduce selective reporting. Ethical approval and data protection considerations apply, particularly in clinical or human-subject research. The term denotes distinct but related activity to replication, in that lisäkokeita may introduce new conditions or questions beyond those in the initial study.

Relation to broader concepts: in English-language literature, similar ideas are described as follow-up studies, replication studies, or robustness checks, depending on the purpose. In Finnish scholarly discourse, lisäkokeita are a recognized part of a research program and grant proposals, used to extend and validate initial findings.
