A laboratory tachistoscopic experiment is a kind of sociological survey recording the conduct rather than the opinion of the respondents. It allows to determine the subjects’ reaction to the presence/absence of visual similarity between two marks.


A participant of the experiment is shown an original image and asked to say if it is on one of the slides that he/she will be shown later. After that a special device is used to show several slides to the testee (usually, 10 series of 10 slides). The suspected copy is in one half of the series (“test series”) and is absent from the other half (“control series”). After each series, the subject is asked if he/she saw the original image. Then, based on the data obtained, the researchers measure the level of visual confusion.
Since the experiment measures the conduct (recognition) across multiple repetitions of one-type stimulus material, the number of participants may be small.

Here some of the most notorious cases where we conducted the experiment:

The data conclusively showed that there was a high risk of confusing similarity between the designations.


• higher data reliability (the subjects’ conduct is recorded);
• faster result (the data are ready 3 days after the order is made rather than 21 days as in the case of surveys);
• less expensive (50% less to pay than for a sociological survey).


• high reputation and accuracy of our surveys;
• flexibility and adaptability;
• personal contact and constant support;
• promptness and feedback;
• lower prices and sizable bonuses for permanent partners.
