FIELD: medicine.SUBSTANCE: presented group of inventions refers to the entertainment industry and can find application in welfare work and community activities aiming at rendering psychological service, as well as in medicine, namely in psychotherapy, prevention of non-infectious diseases, including for improving cardiovascular health, reinforcing the immune system and relieving diabetes mellitus. According to the first version, the psychophysiological laugh response to a clients changed image is induced. That is preceded by generating a signal containing the clients image, changing the signal and presenting the changed image to the client. The clients image is received, and the signal is generated by a photo and/or video device connected to a computer, whereas the clients image signal is changed by means of software installed on the computer. The image changed according to the algorithm of the database of the computer specified in compliance with a certain event and its result is presented. According to the second version, the psychophysiological laugh response to a clients changed speech is induced. That is preceded by generating a signal containing the clients speech, changing the signal and presenting the changed speech to the client. The clients speech is received and transformed, and the signal is generated by an electric acoustic device connected to a computer, whereas the clients speech signal is changed by means of software installed on the computer. The speech changed according to the algorithm of the database of the computer specified in compliance with a certain event and its result is presented.EFFECT: group of inventions ensures the higher effectiveness which is manifested by the increase in the number of psychophysiological laugh responses and the increase in their length over a certain period of time, and maintaining the effect of unexpectedness.21 cl, 3 tbl, 5 exПредлагаемая группа изобретений относится к развлекательной индустрии и может найти прим
