it involves the ability to discriminate positions & movements of body parts based on information that derives the individuals internal environment
body awareness
involves an awareness of body parts by name & location, their relationship to each other, & their capabilities & limitations
ability to..

how much percent of all all sensory
information is derived via visual
system?
80%
what does visual information do?
- Formulate a motor program
- monitor movement activity
- provides feedback
what is the visual process?
- eyes receive light and generate messages
- visual pathways transmit those
messages to brain - visual centers interpret those messages
are all visual structures there at birth?
yes, but several are immature
what do the eyes do between birth & maturity?
they double in size
what age can babies see as well as adults?
12 months
Static visual acuity
- most common form of assessment
- ability to detect detail in STATIONARY object
dynamic visual acuity
- ability to perceive detail in a MOVING object
- ability increases between ages 5 & 12
what age is dynamic visual activity as good as an adult?
12 yrs old
what is object permanence?
realization that objects continue to exist
when they are no longer in view
what are the ages/trends for object permanence?
- under 4 months = none
- 4-8 months= some recognition if object is partly visible
- 8-12 months= signs of it, A-not-B error
- 18 months-2yrs= recognize object is still there
