kasvotesti

Kasvotesti, literally "face test" in Finnish, is a term used to describe tests and assessments that involve human faces. The expression is a compound of kasvot (face) and testi (test). It is not a single standardized measurement, but a generic label for various tasks used in psychology, neuroscience, and security to study face processing, recognition, or verification.

In psychological research, kasvotesti may refer to experiments assessing face recognition memory, facial identity matching, or interpretation of facial expressions. Common elements include showing photographs or digital avatars, asking participants to identify, categorize, or judge emotions, and recording accuracy and reaction times.

In technology and security, kasvotesti can describe biometric tests of face recognition systems or liveness detection, where the system must distinguish a real person from a photo or video. In educational or clinical settings, it may be used to assess social cognition, including the ability to infer emotions or intentions from facial cues.

Limitations of kasvotesti as a concept include variability in stimuli, cultural and demographic influences on facial recognition and expression interpretation, and privacy concerns regarding the collection of facial data. When used in research or industry, tests should be designed to minimize bias and protect participant consent.
