(Demonstrations-Asthesiometer nach Wundt.)
Description: It is worth noting that none of the preceding
research esthesiometers have Wundt's name attached to them, only
this demonstration device, designed for lecture room use. This
device is large enough to make its point in a large lecture hall.
In this device, adjusting the screw on the left side allows a
stimulus weight to be lowered on the hand placed on the right
side of the apparatus, allowing the demonstration of an absolute
threshold for touch. (Expanded caption Copyright 1998, Edward J.
