Perception in Motor
Development
What is Perception?
• A multistage process that takes place in the
BRAIN.
• It includes
– Selection
– Processing
– Organization
– Integration
of Information received from the SENSES
Senses
•
•
•
•
•
•
Sight - Visual
Hearing - Auditory
Smell - Olfactory
Taste
Touch - Tactile
Kinesthetic
Sensory or Sensation is…
• The neural activity
• Stimulus examples are…
triggered by some
– Light
stimulus that activates a
– Sound
sensory receptor and
– Smell
results in sensory nerve • Stimulus in Athletics
impulses traveling the
– Sprinter hears the gun
sensory nerve pathways
– Outfielder hears the bat
to the brain, back to
hit the ball, sees the ball
body and parts, body
flying
reacts & moves
– Golfer feels the ball hit
the sweet spot
Kinesthetic Perception
• Tactile Localization
• Multiple Tactile Points
• Perception of Objects
• Perception of the Body
– Body Awareness

Laterality
Lateral Dominance
Limb Movements
Spatial Orientation
• Perception of Direction
– Directionality
Proprioception
• Proprioception means "sense of self".
– In the limbs, the proprioceptors are sensors that
provide information about joint angle, muscle
length, and tension, which is integrated to give
information about the position of the limb in
space.

“Like a Cat”
• Vestibular Apparatus is crucial to sport &
especially sport activity that involves the body
moving in space (spinning, twisting, rotating,
etc.
• What are 3 specific sport examples whose
athletes have a keen a vestibular apparatus or
sense of body in space?
Visual Perception

Perception of Size Constancy
Perception of Figure-and-Ground
Perception of Whole Objects versus Parts
Depth Perception
Perception of Spatial Orientation
Perception of Movement
