A computer-based experimental laboratory

Describes a computer-based laboratory, developed and applied in behavioral research over a 6-yr period. The laboratory design is described in terms of general capabilities, physical configuration, 2 computer systems (dedicated and time-sharing), and associated equipment. Descriptions are given of computer-managed experiments to illustrate computer advantages: (a) rapid preexperimental assessments of Ss; (b) presentation of instructions, and generation of stimuli and their controlled presentation; (c) improved methodology in executing experimental conditions; (d) recording of computer-mediated social interaction; and (e) control of social interaction (simulated Ss programed to incorporate complex contingencies). Novel methodological capabilities include: on-line interviewing during the experiment, in-process assistance for Ss, implementing complex communication networks (to alter communications, to randomize interaction of Ss, or to implement alterable hierarchical relationships), and real-time data analysis (providing E with in-process results and analyses as bases for possible on-line intervention). The problems of bringing this technology to a wider community of behavioral scientists are discussed, particularly that of getting the investigator into a context governed by unfamiliar procedures.
