Sensory Physiology Kit
Very interesting experiments for the secondary level of education
This sensory physiology kit allows students to conduct various exper-
iments in the fields of hearing, seeing and feeling. All the contents
of the kit are supplied. The experiments and the underlying princi-
ples are of course described in detail in the supplied instruction
manual.
Experiment topics:
• Sense of touch (tactile sense)
• Perception of distances between tactile spots
• Heat and cold perception of the skin
• Blind spot
• Optical and haptic illusions colour vision
• Flicker colours and motion after-effect
• Inversion of the image in the brain using inverting
goggles
• Directional hearing
• Hearing own body noises
Scope of delivery:
Carrying case with foam inserts, instrument
for directional hearing, resonance tube, cali-
pers, tactile hair, cold/hot probe, 4 transpar-
ent plastic cards for geometrical-optical il-
lusions, “blind spot” test card, light-proof
goggles with 8 attachments, 2 inversion
prisms for the goggles, controllable
motor with wall plug transformer,
3 pattern discs, experiment instructions on
CD-ROM (pdf file) in German or English.

Inverting Spectacles
Complete with two fully rotating inverting prisms in a shielded spectacle
frame. The inverting prisms produce a lateral inversion of the rays – the
world thus turns “upside down”. Besides being a lucid demonstration of
the functioning of an inverting prism, experiments involving inverting spec-
tacles encourage a better understanding of the visual process and the func-
tioning of the brain. This also enables a better understanding of the visual
perception of babies. Even the apparently simplest things in life (holding
and picking up objects, drawing, orientating oneself in a room) become
inconceivably difficult.
