Current experiments:

Does pet (dog or cat) in a family influence personality and health of the family members? This is a shorter (about 25 min) questionnaire about dogs, cats, health status and personality. We need the data not only from those with dogs or cats in family, but also from subjects without animals. You can start the test HERE

Influence of Rh blood group on human life – Does a blood group, especially the Rh factorc impact health, personality and performance? This is a complex test containing not only a health questionnaire, but also several computer tests measuring participants’ memory, reaction time, psychomotor performance, intuition and intelligence. At the end of the test the participants will be shown the result of some tests. For us, the most important data are those from people who know their Rh (Rhesus) blood group. Therefore, if you have this information written somewhere, please check it before you start the test. Any other curious people can also take part in the study, of course. Experiment takes about 30-40 minutes. You can start the test HERE

It is necessary to rate all 3 properties. Therefore the test could take 30-60 minutes! (Sorry about this).
