An on-line laboratory in sensation and perception

Three components of a teaching laboratory in perception are described that (1) compare several psychophysical methods for measuring visual illusions, (2) simulate experiments on dark adaptation, and (3) allow participation in auditory demonstrations or experiments. Features of special interest include: interactive use of graphics, software for simulating experiments (such as EXPER SIM, University of Michigan), and use of A/D, D/A, and TTL ports to interface special peripherals.
