| Abstract: | The properties of such phenomena as the appearance of humps at the ascending branch or double peaks in the light curve of
long-period pulsating stars are examined. The characteristics of humps and the average light curves are obtained for a group
of Mira-type stars and semiregular (SRa) variable stars. Correlations between the parameters of the light curves and the characteristics
of the humps for these stars are discussed. The results obtained here are compared with published theoretical models.
