This study takes note of several differences between child supervisors and adult supervisors. Eighteen supervisors of adult psychoanalytic cases, some of whom were also child supervisors, were evaluated by twenty-seven students in training at the Institute for Psychoanalysis in Chicago. The rather complicated methodology employed was called a "Q sort technique." As might be expected, there were differences between the personalities and styles of adult and child analytic supervisors and of female and male supervisors. Some of these differences surprised the investigators. Beiser observes that the women were more aware of the meaning of external relationships. It was also noted that child analysts could communicate their ideas more easily and had a greater interest in the teaching process than did the non-child analysts. An attempt was made to apply some of these findings to the assignment of supervisors to the students. The data were elaborated in seven complicated tables.
