Five Basic Senses

1
Five Basic Senses
?Senses separately sending info to the brain
Vision Hearing Taste Smell Touch
Is this realistic??probably not
2
Common experience suggests that
the senses interact with one another
Vision Hearing Taste Smell Touch
If you see and touch an object, only 1 object is
perceived
3

• somesthetic (body) senses
• KINESTHESIS
• register locomotion in joints
• CUTANEOUS TOUCH
• pressure on the skin

4

• Senses interact and influence each other.
• VISUAL KINESTHESIS
• register locomotion via vision
• Example travelling on a train

5
Example of visual kinesthesis, where you perceive
locomotion via vision
Youre on this train
STOP
Which train is moving?
Where does the interaction between kinesthesis
and vision occur in the eyes? in the brain? in
joints?
You can tell whether or not youre locomoting by
the sense of kinesthesis

Todays Lab Prism Goggles
Where your hand reallyis
Where you hand looks like it is

• How will this affect your felt position of hand?
• How will this affect your control of hand?
• ?Will there be an interaction of the senses?

Goggles visually shift the perceived location of
objects

• Experimental Design
• IV1 type of visual space
• normal vs distorted
• IV2 feedback
• allowed vs not allowed
• DV error
• distance from 0 point in inches

Discussion

• Cond 12 setting up baseline performance
• Cond 3
• error induced by goggles
• consistent shift to one side
• Cond 4 starts at the side, learns to approach
  zero
• Cond 5
• overcompensation (shifts back over other side of
  zero)
• no difference between hands (global adaptation)
