The problem of the interrelation between duration and lengths perception was studied. The experiment where subjects correlated time intervals (duration) with space intervals (lengths) in a certain linear proportionality was carried out by the special constructed psychological installation called "Length-Duration Relation" (LDR) - Installation. In the experiment reported here, the first stimulus (duration), whether of tone or light or both, was presented, and the observer was asked to choose among different rod-lengths the one that seemed to represent the signal duration. Stimulus lengths and durations were developed in proportionality way. The proportionalities were not known by the observers. The "duration-length" correlations given by the experimenter are recognized by the majority of subjects. Preliminary knowledge of the limits pair as a rule leads to the increase of the recognizability of given correlations. In all the series of experiments, in the first subset of signal presentations the latency of "right" responses is considerably shorter than the latency of wrong" ones. The observed phenomenon that differs from the described the tau and kappa effects and synesthesia as well can be considered as a special LDR (Length - Duration Relation)-phenomenon. The obtained experimental data related to the perception of relationships between length and duration and the theoretical analysis of these data can be applied to develop the theory of the human perception of space-time changes that is necessary for the space- time optimization vehicles operating and controlling by men, for working out new type automatic moving devices as well, for diagnostic of mental capability in different ways, robot construction etc.
