The approach to needs outlined in the paper enables the author to suggest two lines of psychological studies. One is devoted to processes of mental reflection of needs and comforts taking place in the shape of emotional-cognitive formations. In this context the problems of genesis of these formations, of their adequacy to man's actual needs and comforts, of man's capacity for reflection of not only his own needs but also of those of others, are set forth. Another line concerns the study of mental processes by means of which a man correlates his needs with resources available for their satisfaction. Here another group of questions arises: how do those processes depend on the amount of resources, how does the chance to use somebody else's activity for the satisfaction of one's own needs affect one's own activity, what are the psychological mechanisms of economical and efficient expenditure of individual and social resources?
