Perception |
Process used to gather and interpret sensory info |
|
Sensation |
Stimulation of sensory receptors |
|
Interpretation is based on |
Past experiences |
|
After processing info |
Formulate a motor response |
|
Visual information |
Provides spatial/temporal information |
|
Kinesthetics |
Provides info about body’s movements without reference to auditory or visual cues |
|
Visual perception |
Dominant modality 80% of info via bison |
|
Eye size |
Doubles from birth to maturity |
|
Newborn eyes |
Thicker retina Poor spatial judgment Not clear images Year 1 now adult like |
|
Visual acuity |
Clearness of vision |
|
Static visual acuity |
Ability to detect detail in stationary object Matures before dynamic |
|
Dynamic acuity |
Ability to detect detail in moving object Improves with age stable in adulthood Men better in static and dynamic |
|
Snellen value |
20/20 eye chart 20/200 sees image 20 ft away as if it were 200 ft away |
|
Factors affecting acuity |
Development of fovea Myelinization # neural connect in visual cortex Strength of ciliary muscles |
|
Object permanence |
Peek a boo Prior to 8 months |
|
Perceptual constancy |
Constant size regardless of angle or distance Age 10-11 reaches maturity |
|
Spatial orientation |
8 years mastered |
|
Figure ground perception |
Identify object from background Improves 4-8 Greater improvement 13-18 |
|
Absolute distance |
Judge distance of object from oneself |
|
Relative distance |
Distance between one object and another |
|

Rapid eye movement |
|
Core of information processing model |
Attention |
|
2 types of attention |
Limited- one thing at a time Serial- attention performed serially. Hard to combine certain activities (chess) |
|
Short term memory |
Limited capacity 30 seconds |
|
Chunking |
5-9 items |
|
Continuous motor skills |
No recognizable beginning or end- riding a bike, running, swimming |
|
Discrete motor skills |
Recognizable beginning and end- throwing, kicking |
|
Hicks law |
Reaction time increases linearly as info load increases- need more time to process |
|
Fitt’s law |
Performing a task quickly often results in less accuracy |
|
Kinesthetic perception |
Awareness of body position in motion |
|
Cutaneous receptors |
Located near skin- touch, pressure, temp, and pain |
|
Proprioreceptor |
Muscle spindle receptors, joints, tendons |
|
Good predictor for overall gross motor skills |
Balance |
