An Evaluation of a Human Development Laboratory: a Study of the Outcome and Process of a Laboratory Learning Experience.

Abstract : This study examined the effects of a Human Development laboratory (HDL) on successful life insurance agents. In order to examine the outcome of the laboratory training fourteen participants of the HDL, and 13 comparison subjects who attended a business seminar, completed two self-report measures before, immediately after, and 8 weeks following their respective schools. In addition, both laboratory and comparison subjects were rated by designated back- home observers on their interpersonel behavior once before, and again 8 weeks following the educational experience. In comparison with the business seminar participants, the laboratory trainees reported greater gains in interpersonal effectiveness immediately after training. However, at the 8-week follow-up, the gains had faded to the extent that the laboratory and comparison groups were approximately at the same level of self-reported interpersonal effectiveness. In addition, the ratings made by the back-home observers failed to demonstrate a difference between the two groups of subjects after training.
