Speaker Name(s): C. Douglas Creelman, PhD Description: The science that we do is advanced by the instruments that are available. In 1891 the University of Toronto Psychology Laboratory was established, the first in the British Empire. Happily many of the instruments and demonstration apparatus from those early times are still available for study. These elegant objects reflect the interests of psychological scientists in auditory and visual perception, response timing, and muscular control, among other areas of study. The talk will demonstrate some of these elegant historic instruments, describe their function, and argue that the science of the time was constrained as well as moved forward by the apparatus, and that this constraint on scientific advancement remains to this day.
