Counselor-trainee response uncertainty and delayed supervisor feedback are two apparent difficulties when looking at the normal practicum procedures from a learning theory frame of reference. Twenty-four counselor-trainees were randomly assigned to three experimental groups and one control group, ie., immediate feedback, feedback and instructions, equipment present, and control. Available to the three experimental groups during treatment was an FM-radio system enabling supervisors to communicate to the counselor-trainees. Pre-and post-audio tapes were selected and rated on empathy. An analyses of variance on the pre- and post- differences in ratings were computed resulting in a significant "F" ratio (p less than .05). Subsequent multiple comparisons showed all experimental groups significant when compared to the control group (p less than .01). The results showed that all experimental conditions significantly increased counselor-trainees' empathic responses. (Author)
