RELEASE FROM PI: Comparison of traditional and computer modules in an experimental psychology laboratory

RELEASE FROM PI is a computer-controlled participatory module designed for use by students in laboratory sections of an experimental psychology course. It allows the student subjects to trace their recall performance across sets of four lists when the fourth list changes in physical characteristics or semantic category. The performance of students participating in this computer module was compared with that of students receiving a traditional procedure with a human experimenter. All other aspects of the laboratory session were equated as much as possible. The recall data showed that the traditional procedure produced better recall and greater release with a semantic shift. However, both methods resulted in roughly equivalent learning (as measured by multiple-choice questions) and student evaluation ratings. Implications for the use of computers in instruction and research are examined.
