Case studies of self-actualizing people according to the ideas of A. Maslow and the criteria of K. Dabrowski are presented. To find people meeting the criteria of Level 4 of the Dabrowski theory, a pool of 21 subjects was established by nomination. All subjects were given the Definition-Response Instrument to assess levels of emotional development. One man and three women were selected for study based on their levels of functioning. A life history was obtained from each subject. Interviews were the richest source of material. Three of the four subjects were found to be self-actualizing. They displayed a commonality possessed by self-actualizers, kindness and simplicity in responding to problems basic to humanity. It was possible to assess the degree of self-actualization with the interviews techniques developed. The interview guide, life history questions, and definitions of the dynamisms of self-actualization are included in appendices. (SLD)
