Easy to use, subject-friendly, powerful and reliable, Psykinematix runs standard psychophysical protocols, presents complex stimuli, collects subject's responses, and analyzes results on the fly. Psykinematix is also a great learning tool to introduce visual perception and to illustrate psychophysical concepts to students.
To learn more about the use of Psykinematix in clinical research, check our VSJ 2009 paper: "Psykinematix: A New Psychophysical Tool for Investigating Visual Impairment due to Neural Dysfunctions".
